Amy
Thank you, Peter. Cambium continued growth in our fourth quarter with revenues of $84.5 million, increasing 4% sequentially ahead of the high end of our outlook of between 80 to $84 million announced during the Q3 22 quarter call. Profitability remains strong with a gross margin of 49.6% near the high end of the outlook and EPS of 36 cents exceeding the high end of the outlook. We had a strong finish to the year in North America with growth in all major product categories and sequential growth for our point-to-multipoint PMP solutions. After record-breaking results during Q3 2022 that included an incremental $5 million in switching revenues, as expected, our enterprise business returned to a normalized run rate in Q4 2022. For the full year 2022, our enterprise business grew 64% to $109.8 million, exceeding the high end of our original forecast. This is after growth of 67% during full year 2021. For 2023, enterprise growth will be from a much higher base, with our initial forecast of growth for the enterprise business of 20% to 30% as we continue to innovate with new Wi-Fi, switching, and cloud-based software solutions. and we continue to gain market share globally. We have grown from approximately 1,500 cumulative Wi-Fi customers at the time of our IPO in mid-2019 to about 18,500 at Q422. We are now at the start of the next wave of high-performance fixed wireless broadband deployments for our PMP business with a ramp of new gigabit solutions including 28 GHz CN-Wave 5G fixed products, an acceleration in the growth of our 60 GHz CN-Wave products, and the introduction of disruptive 6 GHz PMP products during Q4 2022, which delivers industry-leading price performance. Final FCC approval for outdoor use of the 6 GHz spectrum is expected around mid-year 2023. The FCC has already started approving special temporary authority licensing, STA, for proof-of-concept networks. Turning to the results of the fourth quarter 2022. Looking at revenues across our product lines, our PMP business revenues increased 14% sequentially and decreased 20% year-over-year, as service providers are beginning to move from our legacy PMP450 products to the new gigabit technologies. We did see an acceleration of growth for our multi-gig 60 gigahertz CN wave solutions as service providers are gaining an understanding of how to deploy the technology at scale to take advantage of the benefits of multi-gigabit bandwidth, low latency, and efficiency with hybrid fiber and cable networks. The PTB business revenues increased a healthy 38% sequentially, while improving 39% year over year. during Q4-22 due to higher shipments for our federal defense business in North America, as well as growth in EMEA and CALA using Cambium's PTP 700 mission-critical technology for fixed wireless broadband communications. Cambium has been selected to supply our PTP defense products to over 10 key programs of record, POR, for the Department of Defense. We expect continued strong defense shipments during 2023. As expected, our enterprise business declined sequentially, decreasing by $6.3 million, or 17%, after record revenues of $38.3 million during Q3 2022, which included the previously mentioned catch-up shipments for switching, while higher by $6.2 million, or 24%, year-over-year. The year-over-year growth was driven by increased demand for our Wi-Fi 6 and 6E solutions, switching revenues, and growth in our SaaS solutions. For the full year 2022, revenues of $296.9 million decreased 12% from 2021. The 2022 decline was driven by our PMP products, which declined 44% from the prior year, partially offset by the growth of our enterprise business, which had a record year, increasing 64% for the full year 2022, breaking the $100 million threshold for the first time in Cambium's history, while our PTP business grew 10% compared to 2021 revenues due to the strength of our federal defense business. It is notable that our enterprise business represented 37% of the company revenues during calendar year 2022, compared to 20% of revenues for 2021. In the long term, we anticipate our enterprise and PMP businesses will each represent approximately 40% of our total revenues as we ride the new growth S curves, while PTP will represent the remaining 20%. We do foresee the return to modest growth for the PMP business, driven by new product momentum in 6 GHz upon the FCC's approval, as expected to drive revenue growth during the second half of the year, as well as the continued ramp of 28 GHz and 60 GHz millimeter wave solutions, the new 5 GHz and 6 GHz products for both the ePMP and PMP450 product lines. Both 60 GHz and 28 GHz CN wave solutions have recently brought in several multi-million dollar deals, looking at some notable customer wins and new product developments. In North America, Salt Lake City placed an order for 60 gigahertz CN Wave connectivity as part of a smart city deployment. Cambium was selected for our portfolio breadth and ability to deliver backhaul and access with a single management platform. A division of the third largest cable television provider in the United States, serving 3.5 million internet subscribers, introduced a new business service for customers through our system integration partner, FutureTech. The service utilizes Cambium's 60 gigahertz CN-Wave solution to fit between fiber and CBRS assets as part of the new private network offering for multi-gigabit connectivity. We had a large order for 60 gigahertz solutions from a Canadian operator in Alberta, MCSNet, for a 60 gigahertz network build-out. They were attracted to our 60 gigahertz products as it offers gigabit speeds at a much lower total cost of ownership than fiber. They have already deployed in 12 communities so far with a goal of 44 connected communities during 2023. This is an example of where we are seeing a resurgence in our 60 gigahertz business after an initial period of gestation. In the Europe, Middle East, and Africa region, EMEA, we continue to have healthy demand for our enterprise business and are winning larger projects. Cambium had a customer win with a fiber network operator in South Africa, Isisway, for our outdoor Wi-Fi with the goal of connecting households up to 100 megabit per second and a disruptive cost model for the consumer. It this way aims to increase its number of homes connected from 4,500 in December 2022 to 22,000 in 2023. In the Asia Pacific APAC region, we landed our first network as a service NAS win to enable rural connectivity in Sumatra, Indonesia. This first NAS order in the region is for 500 homes and includes our Wi-Fi and CN Maestro X cloud software. This is in addition to our EPMP3000 for fixed wireless broadband access. Upon successful deployment of this first order, we expect a larger multi-year volume agreement. And in Caribbean and Latin America, Cala region, in Brazil, we partnered with Qualcomm in collaboration with the National Telecommunications Agency, Anatel, and Telium to demonstrate the first use of the six gigahertz band in an outdoor area in Campo Velo neighborhood of Sao Paulo. The connection featured Cambium's outdoor Wi-Fi 6 and 6C access points, 6 gigahertz EPM P4600 for fixed wireless infrastructure, CN Matrix wireless savvy switches, and CN Maestro X cloud management software. The demo became available for two months starting on December 3rd for visitors in the surrounding area. The demo included the use of automated frequency coordination, AFC, spectrum sharing platform to ensure that there was no interference with fixed point-to-point systems existing in that region, and to demonstrate its overall speed, performance, and reliability. Turning to upcoming product introductions since our previous quarterly update. While the industry is excited about the future availability of new six gigahertz spectrum to enable the delivery of gigabit data rates to the edge of the network and awaits FCC approval. Cambium also continues to push the envelope with affordable new 5 gigahertz solutions with our EPMP4500 featuring 8x8 MU-MIMO and over 3 gigabits of capacity with up to 80 megahertz channels and enables non-line of sight to select subscribers. The EPMP4500 is a powerful and transformative product which we expect will penetrate the market due to its high performance and affordability compared to other alternatives in the market, especially to take market share from our competition in the service provider space ahead of the FCC's approval of 6 GHz spectrum. Looking at our CN Maestro Cloud software, our end-to-end cloud-powered connectivity solution to manage the network from a single pane of glass. The CN Maestro cloud software continued to experience strong user growth. Total devices under cloud management in Q4 22 was over 898,000, an increase of 4% from Q3 22 and up 21% year over year. Turning to our channel. In Q4 22, we expanded our channel presence by adding over 425 net new channel partners sequentially, and over 1,300 net new channel partners year-over-year, which represents an increase of over 3% sequentially and 11% year-over-year. We continue to expand our reach into new customers around the world. I will now turn the call over to Andrew for a review of our Q4 22 and full year 22 financial results and Q1 23 and full year 23 outlook.
Peter
Thanks, Arjun. Cambium reported revenues of $84.5 million for Q4 22. Revenues increased by 4% quarter over quarter and increased by 7% year over year. On a sequential basis for Q4 22, revenues were higher by $3.3 million. The higher revenues were primarily the result of increased PTP revenues for defense products. and an increase in PMP products as a result of our 60 gigahertz CN wave and EPMP products. While enterprise solutions decreased after a record Q3 22, which included the $5 million catch up in switching revenues due to supply chain shortages in previous quarters. For the full year 2022, revenues of $296.9 million decreased by 39 million or 12% compared to the full year 2021. The decrease is a result of lower PMP revenues, which declined by 89.8 million or 44% compared to 2021 due to product transitions to the next generation fixed gigahertz and 28 gigahertz CN Wave 5G fixed solutions. We had record enterprise revenues of $109.8 million during 2022, which grew by 42.9 million, where 64% compared to 2021. And our PTP revenues increased by $6.3 million to $67.1 million, or an improvement of 10% compared to the full year of 2021, due to strong demand for our defense products. Moving on to our gross margin, our non-GAAP gross margin of 49.6% was better than anticipated, increasing by 540 basis points compared to Q4 21. The year-over-year increase in our non-GAAP gross margin was the result of higher volumes and a greater mix of higher margin enterprise and PTP products and lower freight costs. On a sequential basis, non-GAAP gross margin was lower by 170 basis points compared to Q3-22. The lower quarter-over-quarter non-GAAP gross margin in Q4-22 was the result of a higher mix of lower margin PMP products and as expected, a decline in enterprise switching revenues, offset in part by higher PTP revenues and higher component inventory costs. In Q4-22, our non-GAAP gross profit dollars of $41.9 million increased by $7.1 million compared to the prior year due to higher volumes and improved mix of PTP and enterprise products and lower shipping costs. and increased by $276,000 sequentially, mostly as a result of higher revenues offset in part by the higher component costs due to inflation. For the full year 2022, non-GAAP gross margin improved by 130 basis points to 49.5% compared to 48.2% for 2021 due to an improved mix of our higher margin enterprise and PTP product lines. Our longer term goal remains a consistent non-GAAP gross margin target of 51% to 52% on an annual basis. Non-GAAP operating expenses, including amortization, in Q4 22 decreased by $348,000 when compared to Q4 21 and stood at $28.7 million or 34% of revenues. The decrease in operating expenses compared to the prior year period was primarily due to lower variable compensation and tight controls around headcount, offset by higher sales and marketing costs related to travel and trade shows, and higher wages, while R&D remained flat. When compared to Q3 22, non-GAAP operating expenses increased by approximately $850,000. Quarter over quarter sales and marketing expenses increased primarily because of higher wages and sales accelerators related to our enterprise business. and increased trade show and travel expenditures, while R&D increased as a result of higher staffing costs related to development work on new products, and G&A decreased due to tight cost controls. For the full year 2022, non-GAAP operating expenses decreased by $1.6 million and stood at $112.7 million, compared to $114.3 million for 2021. The lower non-GAAP operating expenses during 2022 reflect less variable compensation offset by higher wages due to inflation. We will continue to maintain our strong cost controls. Non-GAAP operating margin for Q4 22 was 15.6% up from 7.3% during Q4 21 and down from 17% of revenues in Q3 22. For the full year 2022, our non-GAAP operating margin was 11.6% compared to 14.1% in 2021, primarily reflecting lower revenues and less scale resulting in fewer gross profit dollars, despite an improved mix of revenues. Non-GAAP net income for Q4 22 was 10.3 million or 36 cents per diluted share above our previous outlook of between 23 to 27 cents per diluted share. and compared to $4.4 million or $0.16 per diluted share for Q4-21, and non-GAAP net income of $11.3 million or $0.40 per diluted share during Q3-22. The higher non-GAAP net income compared to the prior year period was primarily due to higher gross profit dollars, while lower net income compared to the prior quarter's results was primarily a result of higher sales and marketing costs. For the full year 2022, non-GAAP net income was $26.9 million or $0.94 per diluted share compared to $35.6 million or $1.26 per diluted share in 2021. Adjusted EBITDA for Q4-22 was $14.3 million or 16.9% of revenues compared to $6.7 million or 8.6% of revenues for Q4-21 and compared to $14.7 million or 18.2% of revenues for Q3-22. The full year 2022 adjusted EBITDA was 38.8 million or 13.1% of revenues compared to 51.2 million or 15.3% of revenues for the full year 2021. Our operating model remains solid. We remain committed to consistently driving our adjusted EBITDA to our long-term target of 18 to 19% of revenues. Now moving on to cash flow. Cash provided by operating activities was $4 million for Q422 and compares to $5.6 million for Q421 and $2.2 million for Q322. Our cash flow was negatively impacted as we increased inventories and materials to support new products and to take advantage of supply chain opportunities for the anticipated growth of our business. And we increased accounts receivable as a result of higher revenues. Now turning to the balance sheet, our cash totaled $48.2 million as of December 31-22, an increase of $3.3 million from Q3-22. The sequential increase in cash primarily reflects collections on higher revenues and changes in working capital. Our net inventories of $57.1 million in Q4-22 increased by approximately $23.3 million year over year, while increasing $6.4 million from Q3-22. Inventories were higher sequentially because of an increase in inventories as we continue to grow our business and take advantage of supply chain opportunities. The increased level of inventories reflects anticipated higher demand for federal products, enterprise solutions, and the ramp of new PMP products during the second half of calendar year 23. In summary, the fourth quarter played out better than anticipated. As predicted, our PMP business grew sequentially. Our gross margin remains strong. We continue to see improvement in our supply chain environment. Our backlog remains solid, and we are at the start of new product cycles. During 2023, we expect to gain scale, improve operational efficiency, and make significant progress towards achieving our long-term target operating model. As expected, while the supply chain continues to improve, there are still areas of component shortages in certain products and longer lead times as compared to pre-COVID levels. Moving to the first quarter and full year 2023 financial outlook. Cambium Network's financial outlook does not include the potential impact of any possible future financial transactions, acquisitions, pending legal matters, or other transactions. Considering our current visibility as of today, our Q123 financial outlook is expected to be as follows. Revenues between $74 and $80 million representing growth of approximately 20% to 29% year-over-year, and a decrease of between 5% and 12% sequentially due in part to seasonality in our P&P business and slowing world economies, while our defense business and PTP remain strong. Non-GAAP gross margin of between 49.2% and 50.8%. non-GAAP operating expenses between $30.6 million to $31.6 million, and non-GAAP operating income of between $5.8 and $9 million, interest expense net of approximately $600,000, and non-GAAP net income of between $4.1 and $6.8 million, or net income for diluted share of between 14 cents and 23 cents. Adjusted EBITDA between $6.8 to $10 million and adjusted EBITDA margins between 9.2 and 12.5%, a non-GAAP effective income tax rate of approximately 17 to 21%, and approximately 28.9 million weighted average diluted shares outstanding. Cash requirements are expected as follows. Pay down of debt of $700,000, cash interest of approximately $400,000, and capex of between $3 and $4 million. Full year 2023 financial outlook is expected to be as follows. We expect revenues of between $327 million and $345 million, representing approximately 10% to 16% revenue growth. Non-GAAP gross margin of approximately 50%. Non-GAAP net income of between $33.9 and $36.4 million, or net income per diluted share of between $1.17 to $1.25. Adjusted EBITDA margins of between 14.5 to 15%. And for the year, we expect CapEx to be approximately $14 to $18 million, mainly driven by an expansion in our R&D labs and equipment, along with software costs in connection with new products. I will now turn the call back to Atul for some closing remarks.
Amy
We delivered a solid quarter of results with increased revenues, excellent profitability, and a strong balance sheet, significant new product introductions, and a return to growth for our PMP business driven by 60 gigahertz CNWave, 28 gigahertz CNWave 5G fixed, and the launch of affordable 6 gigahertz fixed wireless PMP solutions. Our enterprise business remains strong, led by Wi-Fi 6 and 6E, wireless-savvy switching products, and an increased offering of our software-as-a-service solutions and excellent onboarding of new large managed service providers. We expect the enterprise business to grow between 20% and 30% during calendar year 23. The Cambium One network integrated wireless fabric has become a reality. providing customers ease of deployment, scalability of networks, and lower total cost of ownership as the world deploys next-generation high-performance wireless broadband networks. During 2022, we diversified and made our business more resilient. We remain focused on judiciously managing our costs, improving our operations, continuing to invest in innovative products to maintain our technology edge and expect increased scale will benefit our future operating results. As we look to 2023, our six gigahertz, 28 gigahertz CN wave 5G fixed technology, millimeter wave products, and upcoming fiber products will expand our markets and continue to propel Cambium in a fixed wireless broadband market. Our defense business is expected to continue growing as national security has become a global issue. And our reach into managed service providers and multi-dwelling units will broaden and strengthen our enterprise business and position us for continued strong growth. We'll expand our software and services offerings and add even more features, security, and functionality into our flagship CN Maestro platform. Our focus will be on solutions that our customers want, keeping a keen eye on how our products mesh with customer applications and network automation. Cambium has now graduated from building just radios to delivering an exceptional customer experience through our extensive broadband solutions that brings delight and confidence. Given the humanitarian crisis unfolding in Turkey last week, Cambium is contributing wireless broadband solutions in the country for connectivity to loved ones to support the citizens and relief workers in the hardest hit areas. I would like to show my appreciation for employees, partners, and customers for their resilience as we return to growth during the second half of calendar 2022. This concludes our prepared remarks. So with that, I would like to turn the call over to Amy and begin the Q&A session.
Operator
We will now open the call for your questions. As a reminder, to ask a question, please press star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press star 11 again. Please limit yourself to one question and one follow-up question. Please stand by while we compile the Q&A roster. And our first question comes from Simon Leopold with Raymond James. Your line is open.
Simon Leopold
Thanks for taking the question. First, I just wanted to knock out a quick clarification. In the prepared remarks, Atul, I think you talked about the mix being roughly 40% PMP, 40% Wi-Fi or enterprise, and 20% P2P. But I wasn't sure what timeframe you were thinking about those targets, whether that was your 2023 view or something longer term. And then I've got a follow-up.
Amy
Yeah. Thanks, Simon. That's a long-term model. Generally, long-term model for us is, you know, two to three-year timeframe. And especially PMP is a very key foundation of Cambium with the resurgence of new products, innovations we are doing with gigabit connectivity, millimeter wave, 5G. So that just tells you the confidence we have that in a long-term model, you will see PMP and enterprise probably equal and PTP about 20%.
Simon Leopold
Thanks. And then a little bit more of, I guess, a trending question is around, I have the impression there's some controversy around the BEAD or Government Broadband Equity Access Deployment Program funding that, if I'm understanding it correctly, they looked at areas where WISPs are providing service and considered them unserved or underserved. And I guess the thought process is that there'd be some risk that the government funds would pay to build out competition to your WISP customers. And I guess I'm just trying to get a better understanding. I think the WISP Association is lobbying the NTIA. If you could maybe tell us a little bit about what's going on and where we are in terms of solving this problem.
Amy
Sure. So Simon, let me address on both RDOF as well as BEAD. The RDOF, which is Rural Development Opportunity Fund, actually just approved two of our customers for a total of about $700 million. And they plan to deploy six gigahertz for that gigabit connectivity. So in the RDOF world, The six gigahertz, CBRS, all that stuff is giving mission-critical connectivity. In the bead world, as we said, this is the Federal Infrastructure Initiative, as we said, it'll be probably early 24 when the dissemination will happen. And I think the results of our, all the interactions we are having with different folks, it is very clear that wireless will provide a very affordable mission-critical infrastructure the way it has provided. in CAF 1 and CAF 2, the Connect America Fund 1 and Connect America Fund 2. So we are pretty confident that economics and the results of art of success will prevail in all the government installations. And also, many of the fiber customers of Cambium are actually using it very successfully in tough terrains and some localities where fiber cannot be So for many practical reasons, I think you will see BEAD also adopted, but RDOC is taking the initiative probably a little earlier.
Simon Leopold
Thank you for that.
Operator
Thank you. One moment for our next question. And our next question comes from Samic Chatterjee with JPMorgan. Your line is open.
Angela
Hi, good afternoon. This is Angela Danon for Samic Chatterjee. I just wanted to ask one question on the customer verticals. So in the service provider vertical, are you seeing any sort of pause in spend from sort of mid-tier providers? And then on the enterprise side, while Cambium doesn't really serve that many traditional enterprise players, you know, are you seeing the macro impacting, you know, hospitality, education, healthcare verticals, and their budgets heading into 2023? And then I have one follow-up.
Amy
Sure. Thanks, Angela. Let me address the service provider first. So in this service provider, they are moving to next-gen architecture. Actually, Cambium has used the pandemic timeframe to completely create the new architectures for gigabit. That's what we did last two years. So what we're finding is that if someone is selling last-generation architecture with slow speeds, you are absolutely right. They are not going to adopt that. But if you have gigabit connectivity, you have 60 gigahertz 5G standards, We are seeing significant activity in our funnel, and the number of customers, number of POCs in E122 increased quite a bit. So the key message, you have to have the next generation architecture, and that's the platforms of the future for Cambium. And we are seeing good growth there. In enterprise, we focus on hospitality, education, and our channel is to manage service providers, and they value ease of deployment. They value economics. And those are the two key differentiation Cambium has. And that's why we are posting 60% plus year-over-year type of growth. So we are not seeing any slowdown there. But even there, Angela, you have to have very high-performance Wi-Fi 6 and 6E products. Again, next-gen architecture. And that has been our key message. New growth S-curves are what's driving the growth right now. Get a follow-up?
Angela
Got it, yes. So I guess moving to my follow-up. So given the ramp in 5G investments and build-outs that are going on in India, could you maybe just walk through what is your exposure to India and your thoughts on potential growth in that region?
Amy
So, Angela, India's 5G, we are very engaged. I think it will take still a year to year and a half for the dust to settle down because their frequency is, I think, 26 gigahertz or so. And we have very good understanding of what will it take. In general, 5G fixed addressable market between 21 to 26 is going to go from 890 million to 1.6 billion. It's a 100% increase in those five, six years. So we think that 28 gigahertz will be a key market, including India, but gestation might take a good solid year to 18 months, but very engaged in that market.
Operator
All right, thank you.
Amy
Thanks, Angela.
Operator
Thank you. One moment for our next question. And our next question comes from Scott Searle with Roth. Your line is open.
Scott Searle
Hey, good afternoon. Thanks for taking the questions. Atul, a lot of new products starting to go out the door. I'm not sure if I heard a number, but I was wondering if you could give us some idea of the magnitude of the contribution of 28 gig and 6 gig. I know it's early days in the just completed fourth quarter. And 60 gig as well, I know, is starting to ramp up. I'm wondering what sort of bundled opportunities you're seeing with the other newer products. And then I had a follow-up.
Amy
Sure. Thanks, Scott. Let me go one by one. So 60 gigahertz, we have now, as we mentioned, we have a couple of million dollars. You know, in every new technology, I look for three tiers. When do you cross 100,000 in revenue? When do you cross half a million? And when do you cross millions? So we are now beginning to see many customers in 60 gigahertz crossing million. What that basically means is they are deploying north of 1,000 subscribers. And as Cambium history shows, every new platform we bring, first we cross the 1,000 barrier, then we cross 10,000 subscriber barriers, then we cross 100,000 subscriber barriers. And it's a four-year cycle. So the key message in 60, I think we are now scaling. Our customers are scaling. The gestation for many of the POCs we talked about last three, four quarters has happened. And this cycle will continue. And where we see acceleration is wireless internet service providers with municipalities, which are using it for public Wi-Fi, video surveillance, and enterprises, particularly logistics, outdoor Wi-Fi, campus connectivity. These are the segments where 6T is expanding. So feel pretty good about that. As we exit at Q4, we felt now our customers are beginning to scale. So that's 60. 28 gigahertz will not have as many customers, but the deal sizes of 28 gigahertz will be probably, in many cases, 5 to 10 times because it's a licensed frequency, and it is very much adopted by Tier 1s and Tier 2s. So what you'll see between 28 and 60 is 60 will be lots of deals, lots of customers, thousands of them, Whereas 28 will be probably hundreds, but the deal sizes on 28 will be much larger. We have over 20 POCs, 20 POCs worldwide, and eight are in production right now. And that tells you how fast Cambium is moving. And just if you look at 2021, we only had two or three. So in last 12 months, our POCs have increased, production customers have increased, and as I mentioned many times in the last few quarters, deal sizes is much, much larger, and they're Duration is also, you know, three to four years, not just one or two years. And let me touch very briefly on six gigahertz. We shipped Q4, our six gigahertz products, and that will support, you know, 10 to 20 POCs. Many of the POCs are turning into non-production, though FCC has not yet approved the final, they have not given the final green signal. But many customers believe that The cost of deployment on towers is very expensive. So they are deploying six gigahertz and some of them are also using the five gigahertz version, which is EPMT 4500, as we mentioned. So all these areas are growing. That's why we are saying 2023 for PMP will be expansion, more second half, because many of these, by the time they enter production and scale and all that, you will see that result. And when we fast forward two, three years, We believe PMP 40%, enterprise 40%, PDP 20% is probably the right steady state distribution.
Scott Searle
Got you. Very helpful. And if I could, for a follow-up, on the 6 gigahertz front, you know, we're waiting for certification and approval from the SEC for the ASC before I guess we start to go into more commercial production. With that in mind, I'm wondering how you're thinking about the ramp up into the second half of this year and what's going to constitute success kind of exiting 2023. And as we think about 2024, how big of an opportunity is that, the 6 gigahertz product line? What would be success? And if I could just briefly kind of dissect between the U.S. international markets, there's been a lot of focus, you know, near term on the U.S. opportunity, but this is certainly a global market. in terms of what's going on with 6 GHz and regulatory approval and the allocation of frequencies. So I'm wondering how you're seeing that shape up on that front and how we should be thinking about that over the next couple of years. Thanks.
Amy
Excellent question, Scott. So first of all, 6 GHz, United States is leading. I think every other country is observing. Brazil is one of the first ones to come on the bandwagon. And in our prepared remarks, we did say, In Sao Paulo, we work with Brazilian authorities like Anatel, and we showed that capability. I think you will see many progressive countries adopt 6 gigahertz, and there's a reason for that. 5 gigahertz is a very well-established frequency, but it's getting noisy. So when government gives you about 1,200 megahertz of very clean spectrum, that's a big deal, like in two decades. There's nothing like this have ever happened, so it's a big deal. So our belief is that U.S. will lead, and many 5 gigahertz WISPs particularly are waiting to expand, and the cost advantage and the performance advantage from 5 gigahertz to 6 gigahertz continues. Remember, when you go to the 60 gigahertz, 28 gigahertz, there's a technological change, and that's why the gestation is needed. That's why the experience is needed before you scale. But when it comes to 6 gigahertz, It's a, it's a edges and see, they know how to do it. So I think the six gigahertz volume is starting to second half. 23 is still early. It'll ratchet up in 24 and 25. And this has been our experience when we introduced Medusa in 2016. With our five gigahertz architecture and three gigahertz architecture, it ran for next four or five years. And that's, I always emphasize that. So I think 23 still for six and second half is a start. but it has a long legs after that. And we are feeling very excited because our customers are getting excited because they can see the price performance is of a different magnitude. That's why I always call it S-curve. It's a new S-curve.
Scott
Great. Thank you. I'll get back in the queue.
Amy
Thanks, Scott.
Scott
Thank you. One moment for our next question.
Operator
And our next question comes from Eric Seppeker. With JMP Securities, your line is open.
Eric Seppeker
Yeah, thanks for taking the question and just following up a little bit more on some of the product segments. How much of your shipments on the enterprise side are Wi-Fi 6 or Wi-Fi 6E at this point? And then secondly, any comments in terms of timing around your fiber products when you think those will start hitting the market and if they would be meaningful contributor in 23?
Amy
Yeah, thanks, Eric. First of all, Wi-Fi 6 transition in Cambium portfolios happened very successfully. I would say majority of our shipments as of today are Wi-Fi 6 and 6E. So that gives you a pretty good indication, majority. And this was a bet we made almost 18 months to two years back and has slid very well. In terms of fiber timing, we are in beta. We will ship volume Q2 timeframe. And our customers are pulling us, actually, because one of the things Cambium is known for is ease of deployment, single pin of glass for management. And they are saying since the government dollars are going to be coming on that side as well, Cambium wants to provide us a nice solution. So our plan is where wireless stops, fiber can take over. Where fiber stops, wireless can take over. single pane of glass to manage and focus on ease of deployment.
Eric Seppeker
Just real quick on the Wi-Fi 6, are you shipping much Wi-Fi 6E at this point?
Amy
Some, yeah, some. But I think Wi-Fi 6E has just so much horsepower in the outdoor arena and indoor arena that I think as of now, some, but I would say most of it is Wi-Fi 6E. But that will change in probably 23 second lab and 24.
spk03
Very good. Thank you. Thanks, Eric.
Operator
Thank you. One moment for our next question. And our next question comes from Paul Essie with William K. Woodruff. Your line is open.
Paul Essie
Yes. Thank you for taking my question. A lot of my questions have been answered, but I've got a couple of quick ones. In the software area, what percent of the software revenues are now within a SAS model? And what is the average? Is it a one-year, two-year, three-year contract that you sign with them?
Peter
Yeah, hi. Thanks for the question. So as a percentage of our total revenue, if you look at SAS-type revenue that's recurring in nature, both software and support services together is about 5% to 6% of our total revenue. And most of those deals, they do vary one year, two year, three, even some five, but I would say on average they're three year deals.
Paul Essie
Okay. Okay. Because I noticed your deferred revenues are starting to build and I just wanted to get an idea. Okay. Okay. And second question, real briefly, have you seen any waiver issues some of the other companies have expressed concern that a year or two out there might be some difficulty getting this product out and meeting some of the specs that the government's putting into the grants they're providing.
Amy
Paul, I didn't understand waiver issue. Could you be more specific?
Paul Essie
Well, labor issues with rolling out the installations. No, we have not heard that.
Amy
No, no, we have not heard that. We had those issues, I would say, in 2020 first half. And then 2022 have a little bit, 2021 people figured out how to work, 2022, no. I would not say we have heard labor issues on, at least for our products.
spk05
Okay. Well, thank you very much. That's all I had.
Amy
Thanks, Paul.
Paul
Thank you. One moment for our next question.
Operator
And our next question comes from Tim Savojo with Northland Capital Markets. Your line is open.
Tim Savojo
Hey, good afternoon and nice quarter. So I wanted to contrast a lot of these positives that you've been discussing in terms of PMP, six gigahertz, new products, 28 gig. I would imagine the fiber product would go in that bucket. some funding for customers from the government. So, you know, there's a lot of positives there. You appear to be guiding to very, very modest growth in PMP in 23, like, you know, low single digits maybe. And I know there's kind of some recovery maybe from a seasonal decline in Q1. But, you know, I guess how do we contrast, you know, are we seeing kind of a fall off, quicker than expected fall off of legacy products On the one hand, that's kind of short term. And then longer term, to get to your target, even if you assume Wi-Fi is slowing, I mean, in the next few years past 23, your growth rates kind of need to be, in PMP, sort of need to be where your enterprise growth rate is now, 25%, 30%, something like that. Is that something you have confidence in or a line of sight to?
Amy
Yeah, Tim, thank you for the question, an excellent question. Let me give you more insight into this. As I said earlier, I look for million-dollar deals because then I know the technologies are scaling. I think that's happening on 60 gigahertz. And even as we speak, some of the networks we are conceiving, even with 60 gigahertz, the numbers are now beginning to be 5,000 to 10,000 subscribers. So that gives us the confidence that these new platforms are now scaling, customers are deploying, and they're getting the confidence that they can truly provide fiber-like speed wirelessly. That's 60. 28 is driven by 5G standards, and I mentioned earlier, in 2026, the TAM of that market for fixed wireless is about 1.6 billion. And we have just started the 5G route. I think the contrast you will see between 60 and 28, 28, we are now, as I said, we have 20 POCs, eight in production, and customers are beginning to scale. The difference will be the deal size on 28 will be far larger. As I said earlier, over a three, four year period, five to 10 times the revenue total deal size because this is a license frequency. Somebody has paid money, they really want to deploy. But for fixed wireless broadband, life cycle is about four to five years. from the start to finish. So I think what we are describing is probably the first 20, 25th percentile in 23 and probably half of 24. And then these networks, this is what we have experienced the last 10 years. So we are sharing with you based on how we are seeing these technologies gestate. They have a really long life in that sense. So I think that gives us the confidence that As the gestation happens over the next three years, that 40-40-20, you know, PMP, enterprise, and PTP is very, very realistic. Because we know the market sizes. We know where our strengths are. We know where our sales teams and channels are. We have excellent channels, especially for PMP markets. And this is what we did last two years, you know, post-COVID, just focused on these next generation platforms. And now we are beginning to get the confidence they're scaling. That's the key word. They're scaling and they're being deployed. Fiber, while we are excited, fiber will go through the same thing. You know, our enterprise quarters used to be 2 million, 3 million, 4 million for first few years. It took us time to kind of learn, scale, deploy. And now we are cranking north of $25 million quarters. So that's what we do. Work with customers, closely with them, learn, and then scale.
Peter
And just to give you a little bit more color as well, that you're right, that there will be some level of seasonality in the first quarter with PMP and the revenues in PMP in the first half of the year when you look at it on a year-over-year basis will decline. But in the second half of the year, and this is how we define, getting back to how we define success, is that we'll be exiting the year with double-digit year-over-year and sequential quarter increases as a result of the new products coming into market in PMP. And that will continue, we believe, to accelerate into 2024. Thanks very much.
Tim Savojo
Sorry. Thanks very much. That was great, Collin.
Operator
Thank you. One moment for our next question. And our next question comes from George Nodder with Jefferies. Your line is open.
George Nodder
Hi, guys. Thanks very much. In the past, you guys have talked a little bit about what channel inventory looks like, whether it was kind of above or below average or average. Could you give us any comments on where you think that is right now?
Peter
Yeah, so when you break it down, I think that the channel inventory on the enterprise side is a little bit higher than what it's been running at um over the over the course of the past 12 months or so some of that is because of of improvements in supply chain and lead times getting a little bit shorter as well and the ability to deliver product into into the distributors so you know i think that's that's what we're seeing on enterprise slightly higher on the pmp side In terms of our inventory out at distributors, it's actually going the other direction. And that's a sign of the distributors getting ready for some of our new products as well. So I think it's somewhat balanced out in that fashion.
George Nodder
Got it. And then I guess I was also just going to ask you about supply chain. I think you kind of answered it there. I mean, are you still seeing any big holdups on supply chain golden screw type issues or Do you think, you know, products are flowing pretty freely now from a manufacturing perspective?
Amy
So, George, first of all, all manufacturing subcontractors and the sites are open and operating. As I said, supply chain is improving, but I don't think it's, you know, it's not yet normalcy. I think it'll be probably mid-23 when it'll reach kind of, for us at least, you know, mid-23, pre-COVID normalcy. There are still shortages on certain parts, but by and large, things have improved. And I think even after Chinese New Year, which is always something we watch carefully, this year, no hiccups. No hiccups. Factories are fully open. Logistics and freight are continually improving. So, so far, so good.
George Nodder
Great. Super. Thank you very much.
Amy
Thanks, George.
Operator
Thank you. And we have a follow-up question for Scott Cyril with Roth Capital Partners. Your line is open.
Scott Searle
Hey, just a quick follow-up on the 6 gig front. I know you're looking at rolling a dual-mode 6 gigahertz solution product. I thought it was in the second quarter around CBRS, right? So it helps you circumvent some issues as it relates to reliability and bead funding. Just wanted to check on the progress of that and make sure that that's still tracking for the second quarter and kind of what the interest level is that you're seeing at least early on in dialogues with wireless ISPs and other carriers on that front. Thanks.
Amy
Yeah, so Scott, the combo product of 5 and 6 will very much be driven by the chip's availability. In the beginning, the 5 gigahertz and 6 gigahertz are two different products. And CBRS1 is a 3 gigahertz separate frequency, completely different product. So I think this year you will see us very much gain the experience and then focus on the combo side based on our experience with the customers and also based on availability of chips and all that. So I don't think the combo part will come right away because I think most of our customers right now are either deploying five or six. And CBRS is a completely different product.
Scott
Great. Thank you.
Amy
Thanks, Scott.
Operator
Thank you. And our next question comes from Timothy Horan with Oppenheimer. Your line is open.
Timothy Horan
Thanks, guys. So you have kind of five, six, I guess almost seven new major products kind of coming out here now. Can you talk a little bit about last time you had this many new services or certain new products coming out and what the impact was? And I mean, should we be kind of expecting a material step up in growth in 24, 25 based on, you know, all the commentary that you're, that you have here? Thanks.
Amy
Thanks, Tim. Yeah. So while there are new products, if you look at when did we introduce them? A lot of it is about gestation. 60 gigahertz actually was introduced by us almost 18 months back. It's just that the gestation is now reaching a point where customers understand how to deploy. They are scaling. 28 gigahertz we introduced about a year back or so, something like that. And that is also beginning to now enter a point where they're going to scale. So I think when we say new products, while these are new platforms, some of them were introduced a year, a year and a half back. The completely new stuff, which is coming now, is the 6 gigahertz, which we just introduced in Q4 last year, about three months back or so. These are different waves. I think the way to think about this is as customers are scaling the networks, they will not deploy all of them at the same time. They will deploy, depending on the region terrain, they'll deploy different frequency and these will overlap over time. And that's what gives us resiliency because we, now we have different frequencies for different countries and regions. We have different performances and different cost structures. Like 28 is a license frequency. Only Tier 1s and Tier 2s can afford that, so we are now working with them. What the 6 is, a lot of WISPs will use 6 gigahertz. It's an extension of 5 gigahertz. And 60 gigahertz is going both in enterprise, as I explained, as well as municipalities and WISPs. So what you're seeing from Cambium is a broad wireless fabric serving some very key segments, and each one of them takes a little different time to gestate.
Timothy Horan
I understand, but they're all kind of hitting the S-curve or the adoption cycle in the next 6 to 12 months. They're all hitting almost at the same time. And the same thing with the Wi-Fi products. It feels like, I know they've all been introduced at different times, but for a whole bunch of reasons, it does feel like we should really see a real acceleration in 2024 and 2025. And I'm not trying to put words in your mouth, but it does seem like they're all really hitting for 2024.
Amy
Yeah, Tim, I agree with you. I think starting in the second half, you will see some of the acceleration as We mentioned 6 gigahertz, for example. But 24, 25, we will benefit from all these investments we have done in the last almost 18 months. That's an accurate statement.
Peter
Thank you. There are product cycles for the older products as well that just in terms of its life cycle will go the other direction as well. So just keep that in mind.
Timothy Horan
Do you have any – I know it's early to give guidance, but, I mean, all things being equal, it should be up from this year's growth rate. Is that pretty fair?
Peter
We really haven't gone through that level of guidance or analysis for 24 yet. But we are, like we said, we are excited about the new S-curves, especially when you look out over the next 12 months and you look at the 6 gigahertz product and the level of volume that that could mean in starting a new S-curve in the PMP side of the business.
Timothy Horan
And do we have any sense of the TAM of the 6 gigahertz product?
Amy
Yeah, I think the way, Tim, you want to think about this is 6 gigahertz is an extension of 5. And the 5 gigahertz point-to-multipoint was about a billion-dollar temp. The way you want to think about this is that billion-dollar will churn and extend into the 6 gigahertz. That's probably the easiest way to think about it. Thank you.

Amy
Thank you, Peter. Cambium continued growth in our fourth quarter with revenues of $84.5 million increasing 4% sequentially ahead of the high end of our outlook of between 80 to 84 million dollars announced during the Q3 22 quarter call. Profitability remains strong with a gross margin of 49.6% near the high end of the outlook and EPS of 36 cents exceeding the high end of the outlook. We had a strong finish to the year in North America with growth in all major product categories and sequential growth for our point-to-multipoint PMP solutions. After record-breaking results during Q3 2022 that included an incremental $5 million in switching revenues, as expected, our enterprise business returned to a normalized run rate in Q4 2022. For the full year 2022, our enterprise business grew 64% to $109.8 million, exceeding the high end of our original forecast. This is after growth of 67% during full year 2021. For 2023, enterprise growth will be from a much higher base, with our initial forecast of growth for the enterprise business of 20 to 30%, as we continue to innovate with new Wi-Fi, switching, and cloud-based software solutions. and we continue to gain market share globally. We have grown from approximately 1,500 cumulative Wi-Fi customers at the time of our IPO in mid-2019 to about 18,500 at Q422. We are now at the start of the next wave of high-performance fixed wireless broadband deployments for our PMP business with a ramp of new gigabit solutions including 28 GHz CN-Wave 5G fixed products, an acceleration in the growth of our 60 GHz CN-Wave products, and the introduction of disruptive 6 GHz PMP products during Q4 2022, which delivers industry-leading price performance. Final FCC approval for outdoor use of the 6 GHz spectrum is expected around mid-year 2023. The FCC has already started approving special temporary authority licensing, STA, for proof-of-concept networks. Turning to the results of the fourth quarter 2022. Looking at revenues across our product lines, our PMP business revenues increased 14% sequentially and decreased 20% year-over-year, as service providers are beginning to move from our legacy PMP450 products to the new gigabit technologies. We did see an acceleration of growth for our multi-gig 60 gigahertz CN wave solutions, as service providers are gaining an understanding of how to deploy the technology at scale to take advantage of the benefits of multi-gigabit bandwidth, low latency, and efficiency with hybrid fiber and cable networks. The PTP business revenues increased a healthy 38% sequentially, while improving 39% year over year. during Q4-22 due to higher shipments for our federal defense business in North America, as well as growth in EMEA and CALA using Cambium's PTP 700 mission-critical technology for fixed wireless broadband communications. Cambium has been selected to supply our PTP defense products to over 10 key programs of record, POR, for the Department of Defense. We expect continued strong defense shipments during 2023. As expected, our enterprise business declined sequentially, decreasing by $6.3 million, or 17%, after record revenues of $38.3 million during Q3 2022, which included the previously mentioned catch-up shipments for switching, while higher by $6.2 million, or 24%, year-over-year. The year-over-year growth was driven by increased demand for our Wi-Fi 6 and 6E solutions, switching revenues, and growth in our SaaS solutions. For the full year 2022, revenues of $296.9 million decreased 12% from 2021. The 2022 decline was driven by our PMP products, which declined 44% from the prior year, partially offset by the growth of our enterprise business, which had a record year, increasing 64% for the full year 2022, breaking the $100 million threshold for the first time in Cambium's history, while our PTP business grew 10% compared to 2021 revenues due to the strength of our federal defense business. It is notable that our enterprise business represented 37% of the company revenues during calendar year 2022, compared to 20% of revenues for 2021. In the long term, we anticipate our enterprise and PMP businesses will each represent approximately 40% of our total revenues as we ride the new growth S curves, while PTP will represent the remaining 20%. We do foresee the return to modest growth for the PMP business, driven by new product momentum in 6 GHz upon the FCC's approval, as expected to drive revenue growth during the second half of the year, as well as the continued ramp of 28 GHz and 60 GHz millimeter wave solutions, the new 5 GHz and 6 GHz products for both the ePMP and PMP450 product lines. Both 60 GHz and 28 GHz CN wave solutions have recently brought in several multi-million dollar deals, looking at some notable customer wins and new product developments. In North America, Salt Lake City placed an order for 60 gigahertz CN Wave connectivity as part of a smart city deployment. Cambium was selected for our portfolio breadth and ability to deliver backhaul and access with a single management platform. A division of the third largest cable television provider in the United States, serving 3.5 million internet subscribers, introduced a new business service for customers through our system integration partner, FutureTech. The service utilizes Cambium's 60 gigahertz CN-Wave solution to fit between fiber and CBRS assets as part of the new private network offering for multi-gigabit connectivity. We had a large order for 60 gigahertz solutions from a Canadian operator in Alberta, MCSNet, for a 60 gigahertz network build-out. They were attracted to our 60 gigahertz products as it offers gigabit speeds at a much lower total cost of ownership than fiber. They have already deployed in 12 communities so far with a goal of 44 connected communities during 2023. This is an example of where we are seeing a resurgence in our 60 gigahertz business after an initial period of gestation. In the Europe, Middle East, and Africa region, EMEA, we continue to have healthy demand for our enterprise business and are winning larger projects. Cambium had a customer win with a fiber network operator in South Africa, Isisway, for our outdoor Wi-Fi with a goal of connecting households up to 100 megabit per second and a disruptive cost model for the consumer. This way aims to increase its number of homes connected from 4,500 in December 2022 to 22,000 in 2023. In the Asia Pacific APAC region, we landed our first network as a service NAS win to enable rural connectivity in Sumatra, Indonesia. This first NAS order in the region is for 500 homes and includes our Wi-Fi and CN Maestro X cloud software. This is in addition to our EPMP3000 for fixed wireless broadband access. Upon successful deployment of this first order, we expect a larger multi-year volume agreement. And in Caribbean and Latin America, Cala region, in Brazil, we partnered with Qualcomm in collaboration with the National Telecommunications Agency, Anatel, and Telium to demonstrate the first use of the six gigahertz band in an outdoor area in Campo Velo neighborhood of Sao Paulo. The connection featured Cambium's outdoor Wi-Fi 6 and 6C access points, 6 gigahertz EPM P4600 for fixed wireless infrastructure, CN Matrix wireless savvy switches, and CN Maestro X cloud management software. The demo became available for two months starting on December 3rd for visitors in the surrounding area. The demo included the use of automated frequency coordination, AFC, spectrum sharing platform to ensure that there was no interference with fixed point-to-point systems existing in that region, and to demonstrate its overall speed, performance, and reliability. Turning to upcoming product introductions since our previous quarterly update. While the industry is excited about the future availability of new six gigahertz spectrum to enable the delivery of gigabit data rates to the edge of the network and awaits FCC approval. Cambium also continues to push the envelope with affordable new 5 gigahertz solutions with our EPMP 4500 featuring 8x8 MU MIMO and over 3 gigabits of capacity with up to 80 megahertz channels and enables non-line-of-sight to select subscribers. The EPMP4500 is a powerful and transformative product which we expect will penetrate the market due to its high performance and affordability compared to other alternatives in the market, especially to take market share from our competition in the service provider space ahead of the FCC's approval of 6 GHz spectrum. Looking at our CN Maestro Cloud software, our end-to-end cloud-powered connectivity solution to manage the network from a single pane of glass. The CN Maestro cloud software continued to experience strong user growth. Total devices under cloud management in Q4 22 was over 898,000, an increase of 4% from Q3 22 and up 21% year over year. Turning to our channel. In Q4 22, we expanded our channel presence by adding over 425 net new channel partners sequentially. and over 1,300 net new channel partners year-over-year, which represents an increase of over 3% sequentially and 11% year-over-year. We continue to expand our reach into new customers around the world. I will now turn the call over to Andrew for a review of our Q4 22 and full year 22 financial results and Q1 23 and full year 23 outlook.
Peter
Thanks, Arjun. Cambium reported revenues of $84.5 million for Q4 22. Revenues increased by 4% quarter over quarter and increased by 7% year over year. On a sequential basis for Q4 22, revenues were higher by $3.3 million. The higher revenues were primarily the result of increased PTP revenues for defense products and an increase in PMP products as a result of our 60 gigahertz CN wave and EPMP products. While enterprise solutions decreased after a record Q3 22, which included the $5 million catch up in switching revenues due to supply chain shortages in previous quarters. For the full year 2022, revenues of $296.9 million decreased by 39 million or 12% compared to the full year 2021. The decrease is a result of lower PMP revenues, which declined by 89.8 million or 44% compared to 2021 due to product transitions to the next generation, six gigahertz and 28 gigahertz CNWave 5G fixed solutions. We had record enterprise revenues of $109.8 million during 2022, which grew by 42.9 million or 64% compared to 2021. and our PTP revenues increased by $6.3 million to $67.1 million, or an improvement of 10% compared to the full year of 2021, due to strong demand for our defense products. Moving on to our gross margin, our non-GAAP gross margin of 49.6% was better than anticipated, increasing by 540 basis points compared to Q4 21. The year-over-year increase in our non-GAAP gross margin was the result of higher volumes and a greater mix of higher margin enterprise and PTP products and lower freight costs. On a sequential basis, non-GAAP gross margin was lower by 170 basis points compared to Q3-22. The lower quarter-over-quarter non-GAAP gross margin in Q4-22 was the result of a higher mix of lower margin PMP products and as expected, a decline in enterprise switching revenues, offset in part by higher PTP revenues and higher component inventory costs. In Q4-22, our non-GAAP gross profit dollars of $41.9 million increased by $7.1 million compared to the prior year due to higher volumes and improved mix of PTP and enterprise products and lower shipping costs. and increased by $276,000 sequentially, mostly as a result of higher revenues offset in part by the higher component costs due to inflation. For the full year 2022, non-GAAP gross margin improved by 130 basis points to 49.5% compared to 48.2% for 2021 due to an improved mix of our higher margin enterprise and PTP product lines. Our longer term goal remains a consistent non-GAAP gross margin target of 51 to 52% on an annual basis. Non-GAAP operating expenses, including amortization in Q4 22 decreased by 348,000 when compared to Q4 21 and stood at 28.7 million or 34% of revenues. The decrease in operating expenses compared to the prior year period was primarily due to lower variable compensation and tight controls around headcount, offset by higher sales and marketing costs related to travel and trade shows, and higher wages, while R&D remained flat. When compared to Q3 22, non-GAAP operating expenses increased by approximately $850,000. Quarter over quarter sales and marketing expenses increased primarily because of higher wages and sales accelerators related to our enterprise business. and increased trade show and travel expenditures, while R&D increased as a result of higher staffing costs related to development work on new products, and G&A decreased due to tight cost controls. For the full year 2022, non-GAAP operating expenses decreased by $1.6 million and stood at $112.7 million, compared to $114.3 million for 2021. The lower non-GAAP operating expenses during 2022 reflect less variable compensation offset by higher wages due to inflation. We will continue to maintain our strong cost controls. Non-GAAP operating margin for Q4 22 was 15.6% up from 7.3% during Q4 21 and down from 17% of revenues in Q3 22. For the full year 2022, our non-GAAP operating margin was 11.6% compared to 14.1% in 2021, primarily reflecting lower revenues and less scale resulting in fewer gross profit dollars, despite an improved mix of revenues. Non-GAAP net income for Q4 22 was 10.3 million or 36 cents per diluted share above our previous outlook of between 23 to 27 cents per diluted share. and compared to $4.4 million or $0.16 per diluted share for Q4-21, and non-GAAP net income of $11.3 million or $0.40 per diluted share during Q3-22. The higher non-GAAP net income compared to the prior year period was primarily due to higher gross profit dollars, while lower net income compared to the prior quarter's results was primarily a result of higher sales and marketing costs. For the full year 2022, non-GAAP net income was $26.9 million or $0.94 per diluted share compared to $35.6 million or $1.26 per diluted share in 2021. Adjusted EBITDA for Q4-22 was $14.3 million or 16.9% of revenues compared to $6.7 million or 8.6% of revenues for Q4-21 and compared to $14.7 million or 18.2% of revenues for Q3-22. The full year 2022 adjusted EBITDA was 38.8 million or 13.1% of revenues compared to 51.2 million or 15.3% of revenues for the full year 2021. Our operating model remains solid. We remain committed to consistently driving our adjusted EBITDA to our long-term target of 18 to 19% of revenues. Now moving on to cash flow. Cash provided by operating activities was $4 million for Q422 and compares to $5.6 million for Q421 and $2.2 million for Q322. Our cash flow was negatively impacted as we increased inventories and materials to support new products and to take advantage of supply chain opportunities for the anticipated growth of our business. And we increased accounts receivable as a result of higher revenues. Now turning to the balance sheet, our cash totaled $48.2 million as of December 31-22, an increase of $3.3 million from Q3-22. The sequential increase in cash primarily reflects collections on higher revenues and changes in working capital. Our net inventories of $57.1 million in Q4-22 increased by approximately $23.3 million year-over-year, while increasing $6.4 million from Q3-22. Inventories were higher sequentially because of an increase in inventories as we continued to grow our business and take advantage of supply chain opportunities. The increased level of inventories reflects anticipated higher demand for federal products, enterprise solutions, and the ramp of new PMP products during the second half of calendar year 23. In summary, the fourth quarter played out better than anticipated. As predicted, our PMP business grew sequentially. Our gross margin remains strong. We continue to see improvement in our supply chain environment. Our backlog remains solid, and we are at the start of new product cycles. During 2023, we expect to gain scale, improve operational efficiency, and make significant progress towards achieving our long-term target operating model. As expected, while the supply chain continues to improve, there are still areas of component shortages in certain products and longer lead times as compared to pre-COVID levels. Moving to the first quarter and full year 2023 financial outlook. Cambium Network's financial outlook does not include the potential impact of any possible future financial transactions, acquisitions, pending legal matters, or other transactions. Considering our current visibility as of today, our Q1 2023 financial outlook is expected to be as follows. Revenues between $74 and $80 million representing growth of approximately 20% to 29% year-over-year, and a decrease of between 5% and 12% sequentially due in part to seasonality in our P&P business and slowing world economies, while our defense business and PTP remain strong. Non-GAAP gross margin of between 49.2% and 50.8%. non-GAAP operating expenses between $30.6 million to $31.6 million, and non-GAAP operating income of between $5.8 and $9 million, interest expense net of approximately $600,000, and non-GAAP net income of between $4.1 and $6.8 million, or net income for diluted share of between 14 cents and 23 cents. Adjusted EBITDA between $6.8 to $10 million and adjusted EBITDA margins between 9.2 and 12.5%, a non-GAAP effective income tax rate of approximately 17 to 21%, and approximately 28.9 million weighted average diluted shares outstanding. Cash requirements are expected as follows. Pay down of debt of $700,000, cash interest of approximately $400,000, and CapEx of between $3 and $4 million. Full year 2023 financial outlook is expected to be as follows. We expect revenues of between $327 million and $345 million, representing approximately 10% to 16% revenue growth. Non-GAAP gross margin of approximately 50%. Non-GAAP net income of between $33.9 and $36.4 million, or net income per diluted share of between $1.17 to $1.25. Adjusted EBITDA margins of between 14.5 to 15%. And for the year, we expect CapEx to be approximately $14 to $18 million, mainly driven by an expansion in our R&D labs and equipment, along with software costs in connection with new products. I will now turn the call back to Atul for some closing remarks.
Amy
We delivered a solid quarter of results with increased revenues, excellent profitability, and a strong balance sheet, significant new product introductions, and a return to growth for our PMP business driven by 60 gigahertz CNWave, 28 gigahertz CNWave 5G fixed, and the launch of affordable 6 gigahertz fixed wireless PMP solutions. Our enterprise business remains strong, led by Wi-Fi 6 and 6E, wireless-savvy switching products, and an increased offering of our software-as-a-service solutions, an excellent onboarding of new large managed service providers. We expect the enterprise business to grow between 20% and 30% during calendar year 23. The Cambium One network integrated wireless fabric has become a reality. providing customers ease of deployment, scalability of networks, and lower total cost of ownership as the world deploys next-generation high-performance wireless broadband networks. During 2022, we diversified and made our business more resilient. We remain focused on judiciously managing our costs, improving our operations, continuing to invest in innovative products to maintain our technology edge and expect increased scale will benefit our future operating results. As we look to 2023, our six gigahertz, 28 gigahertz CN wave 5G fixed technology, millimeter wave products, and upcoming fiber products will expand our markets and continue to propel Cambium in a fixed wireless broadband market. Our defense business is expected to continue growing as national security has become a global issue. And our reach into managed service providers and multi-dwelling units will broaden and strengthen our enterprise business and position us for continued strong growth. We'll expand our software and services offerings and add even more features, security, and functionality into our flagship CN Maestro platform. Our focus will be on solutions that our customers want, keeping a keen eye on how our products mesh with customer applications and network automation. Cambium has now graduated from building just radios to delivering an exceptional customer experience through our extensive broadband solutions. That brings delight and confidence. Given the humanitarian crisis unfolding in Turkey last week, Cambium is contributing wireless broadband solutions in the country for connectivity to loved ones to support the citizens and relief workers in the hardest hit areas. I would like to show my appreciation for employees, partners, and customers for their resilience as we return to growth during the second half of calendar 2022. This concludes our prepared remarks. So with that, I would like to turn the call over to Amy and begin the Q&A session.
Operator
We will now open the call for your questions. As a reminder, to ask a question, please press star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press star 11 again. Please limit yourself to one question and one follow-up question. Please stand by while we compile the Q&A roster. And our first question comes from Simon Leopold with Raymond James. Your line is open.
Simon Leopold
Thanks for taking the question. First, I just wanted to knock out a quick clarification. In the prepared remarks, Atul, I think you talked about the mix being roughly 40% PMP, 40% Wi-Fi or enterprise, and 20% P2P. But I wasn't sure what timeframe you were thinking about those targets, whether that was your 2023 view or something longer term. And then I've got a follow-up.
Amy
Yeah. Thanks, Simon. That's a long-term model. Generally, long-term model for us is, you know, two to three-year timeframe. And especially PMP is a very key foundation of Cambium with the resurgence of new products, innovations we are doing with gigabit connectivity, millimeter wave, 5G. So that just tells you the confidence we have that in a long-term model, you will see PMP and enterprise probably equal and PTP about 20%.
Simon Leopold
Thanks. And then a little bit more of, I guess, a trending question is around, I have the impression there's some controversy around the BEAD or Government Broadband Equity Access Deployment Program funding that, if I'm understanding it correctly, they looked at areas where WISPs are providing service and considered them unserved or underserved. And I guess the thought process is that there'd be some risk that the government funds would pay to build out competition to your WISP customers. And I guess I'm just trying to get a better understanding. I think the WISP Association is lobbying the NTIA. If you could maybe tell us a little bit about what's going on and where we are in terms of solving this problem.
Amy
Sure. So Simon, let me address on both RDOF as well as BEAD. The RDOF, which is Rural Development Opportunity Fund, actually just approved two of our customers for a total of about $700 million. And they plan to deploy six gigahertz for that gigabit connectivity. So in the RDOF world, The six gigahertz, CBRS, all that stuff is giving mission-critical connectivity. In the bead world, as we said, this is the Federal Infrastructure Initiative, as we said, it'll be probably early 24 when the dissemination will happen. And I think the results of our, all the interactions we are having with different folks, it is very clear that wireless will provide a very affordable mission-critical infrastructure the way it has provided. in CAF 1 and CAF 2, the Connect America Fund 1 and Connect America Fund 2. So we are pretty confident that economics and the results of art of success will prevail in all the government installations. And also, many of the fiber customers of Cambium are actually using it very successfully in tough terrains and some localities where fiber cannot be So for many practical reasons, I think you will see BEAD also adopted, but RDOC is taking the initiative probably a little earlier. Thank you for that.
Operator
Thank you. One moment for our next question. And our next question comes from Samic Chatterjee with JPMorgan. Your line is open.
Angela
Hi, good afternoon. This is Angela Danon for Samic Chatterjee. I just wanted to ask one question on the customer verticals. So in the service provider vertical, are you seeing any sort of pause in spend from sort of mid-tier providers? And then on the enterprise side, while Cambium doesn't really serve that many traditional enterprise players, you know, are you seeing the macro impacting, you know, hospitality, education, healthcare verticals and their budgets heading into 2023? And then I have one follow-up.
Amy
Sure. Thanks, Angela. Let me address the service provider first. So in this service provider, they are moving to next-gen architecture. Actually, Cambium has used the pandemic timeframe to completely create the new architectures for gigabit. That's what we did last two years. So what we're finding is that if someone is selling last-generation architecture with slow speeds, you are absolutely right. They are not going to adopt that. But if you have gigabit connectivity, you have 60 gigahertz 5G standards, We are seeing significant activity in our funnel, and the number of customers, number of POCs in E122 increased quite a bit. So the key message, you have to have the next generation architecture, and that's the platforms of the future for Cambium. And we are seeing good growth there. In enterprise, we focus on hospitality, education, and our channel is to manage service providers, and they value ease of deployment. They value economics. And those are the two key differentiation Cambium has. And that's why we are posting 60% plus year-over-year type of growth. So we are not seeing any slowdown there. But even there, Angela, you have to have very high-performance Wi-Fi 6 and 6E products. Again, next-gen architecture. And that has been our key message. New growth S-curves are what's driving the growth right now. Get a follow-up?
Angela
Got it, yes. So I guess moving to my follow-up. So given the ramp in 5G investments and build-outs that are going on in India, could you maybe just walk through what is your exposure to India and your thoughts on potential growth in that region?
Amy
So, Angela, India's 5G, we are very engaged. I think it will take still a year to year and a half for the dust to settle down because their frequency is, I think, 26 gigahertz or so. And we have very good understanding of what will it take. In general, 5G fixed addressable market between 21 to 26 is going to go from 890 million to 1.6 billion. It's a 100% increase in those five, six years. So we think that 28 gigahertz will be a key market, including India, but gestation might take a good solid year to 18 months, but very engaged in that market.
Operator
Thank you.
Amy
Thanks, Angela.
Operator
Thank you. One moment for our next question. And our next question comes from Scott Searle with Roth. Your line is open.
Scott Searle
Hey, good afternoon. Thanks for taking the questions. A lot of new products starting to go out the door. I'm not sure if I heard a number, but I was wondering if you could give us some idea of the magnitude of the contribution of 28 gig and 6 gig. I know it's early days in the just completed fourth quarter. And 60 gig as well, I know, is starting to ramp up. I'm wondering what sort of bundled opportunities you're seeing with the other newer products. And then I had a follow-up.
Amy
Sure. Thanks, Scott. Let me go one by one. So 60 gigahertz, we have now, as we mentioned, we have a couple of million dollars. You know, in every new technology, I look for three tiers. When do you cross 100,000 in revenue? When do you cross half a million? And when do you cross millions? So we are now beginning to see many customers in 60 gigahertz crossing million. What that basically means is they are deploying north of 1,000 subscribers. And as Cambium history shows, every new platform we bring, first we cross 1,000 barriers, then we cross 10,000 subscriber barriers, then we cross 100,000 subscriber barriers. And it's a four-year cycle. So the key message on 60, I think we are now scaling. Our customers are scaling. The gestation for many of the POCs we talked about last three, four quarters has happened. And this cycle will continue. And where we see acceleration is wireless internet service providers with municipalities, which are using it for public Wi-Fi, video surveillance, and enterprises, particularly logistics, outdoor Wi-Fi, campus connectivity. These are the segments where 60 is expanding. So feel pretty good about that. As we exit at Q4, we felt now our customers are beginning to scale. So that's 60. 28 gigahertz will not have as many customers, but the deal sizes of 28 gigahertz will be probably, in many cases, 5 to 10 times because it's a licensed frequency, and it is very much adopted by Tier 1s and Tier 2s. So what you'll see between 28 and 60 is 60 will be lots of deals, lots of customers, thousands of them, Whereas 28 will be probably hundreds, but the deal sizes on 28 will be much larger. We have over 20 POCs, 20 POCs worldwide, and eight are in production right now. And that tells you how fast Cambium is moving. And just if you look at 2021, we only had two or three. So in last 12 months, our POCs have increased, production customers have increased, and as I mentioned many times in the last few quarters, deal sizes is much, much larger, and they're duration is also you know three to four years not just one or two years and let me touch very briefly on six gigahertz we shipped uh q4 uh our six gigahertz products and that will support you know 10 to 20 uh pocs many of the pocs are turning into now production though fcc has not yet approved the final they have not given the final green signal but many customers believe that The cost of deployment on towers is very expensive. So they are deploying six gigahertz and some of them are also using the five gigahertz version, which is EPMP 4500, as we mentioned. So all these areas are growing. That's why we are saying 2023 for PMP will be expansion, more second half, because many of these, by the time they enter production and scale and all that, you will see that result. And when we fast forward two, three years, We believe PMP 40%, enterprise 40%, PTP 20% is probably the right steady state distribution.
Scott Searle
Got you. Very helpful. And if I could, for a follow-up, on the 6 gigahertz front, you know, we're waiting for certification and approval from the SEC for the ASC before I guess we start to go into more commercial production. With that in mind, I'm wondering how you're thinking about the ramp up into the second half of this year and what's going to constitute success kind of exiting 2023. And as we think about 2024, how big of an opportunity is that, the 6 gigahertz product line? What would be success? And if I could just briefly kind of dissect between the U.S. international markets, there's been a lot of focus, you know, near term on the U.S. opportunity, but this is certainly a global market. in terms of what's going on with 6 GHz and regulatory approval and the allocation of frequencies. So I'm wondering how you're seeing that shape up on that front and how we should be thinking about that over the next couple of years. Thanks.
Amy
Excellent question, Scott. So first of all, 6 GHz, United States is leading. I think every other country is observing. Brazil is one of the first ones to come on the bandwagon. And in our prepared remarks, we did say, In Sao Paulo, we work with Brazilian authorities like Anatel, and we showed that capability. I think you will see many progressive countries adopt six gigahertz, and there's a reason for that. Five gigahertz is a very well-established frequency, but it is getting noisy. So when government gives you about 1,200 megahertz of very clean spectrum, that's a big deal, like in two decades. There's nothing like this have ever happened, so it's a big deal. So our belief is that U.S. will lead, and many 5 gigahertz WISPs particularly are waiting to expand, and the cost advantage and the performance advantage from 5 gigahertz to 6 gigahertz continues. Remember, when you go to the 60 gigahertz, 28 gigahertz, there's a technological change, and that's why the gestation is needed. That's why the experience is needed before you scale. But when it comes to 6 gigahertz, It's a adjacency. They know how to do it. So I think the six gigahertz volume is starting the second half, 23, is still early. It'll ratchet up in 24 and 25. And this has been our experience. When we introduced Medusa in 2016 with our five gigahertz architecture and three gigahertz architecture, it ran for next four, five years. And that's, I always emphasize that. So I think 23 still for sixth and second half is a start. but it has a long legs after that. And we are feeling very excited because our customers are getting excited because they can see the price performance is of a different magnitude. That's why I always call it S-curve. It's a new S-curve.
Scott
Great. Thank you. I'll get back in the queue.
Amy
Thanks, Scott.
Scott
Thank you. One moment for our next question.
Operator
And our next question comes from Eric Seppeker. With JIP Securities, your line is open.
Eric Seppeker
Yeah, thanks for taking the question and just following up a little bit more on some of the product segments. One, how much of your shipments on the enterprise side are Wi-Fi 6 or Wi-Fi 6E at this point? And then secondly, any comments in terms of timing around your fiber products when you think those will start hitting the market and if they would be meaningful contributor in 23?
Amy
Yeah, thanks, Eric. First of all, Wi-Fi 6 transition in Cambium portfolios happened very successfully. I would say majority of our shipments as of today are Wi-Fi 6 and 6E. So that gives you a pretty good indication, majority. And this was a bet we made almost 18 months to two years back and has slid very well. In terms of fiber timing, we are in beta. We will ship volume Q2 timeframe. And our customers are pulling us, actually, because one of the things Cambium is known for is ease of deployment, single pin of glass for management. And they are saying since the government dollars are going to be coming on that side as well, Cambium wants to provide us a nice solution. So our plan is where wireless stops, fiber can take over. Where fiber stops, wireless can take over. single pane of glass to manage and focus on ease of deployment.
Eric Seppeker
Just real quick on the Wi-Fi 6, are you shipping much Wi-Fi 6E at this point?
Amy
Some, yeah, some. But I think Wi-Fi 6E has just so much horsepower in the outdoor arena and indoor arena that I think as of now, some, but I would say most of it is Wi-Fi 6E. But that will change in probably 23 second lab and 24.
spk03
Very good. Thank you. Thanks, Eric.
Operator
Thank you. One moment for our next question. And our next question comes from Paul Essie with William K. Woodruff. Your line is open.
Paul Essie
Yes. Thank you for taking my question. A lot of my questions have been answered, but I've got a couple of quick ones. In the software area, what percent of the software revenues are now within a SAS model? And what is the average? Is it a one-year, two-year, three-year contract that you sign with them?
Peter
Yeah, hi. Thanks for the question. So as a percentage of our total revenue, if you look at SAS-type revenue that's recurring in nature, both software and support services together is about 5% to 6% of our total revenue. And most of those deals, they do vary one year, two year, three, even some five, but I would say on average they're three year deals.
Paul Essie
Okay. Okay. Because I noticed your deferred revenues are starting to build and I just wanted to get an idea. Okay. Okay. And second question, real briefly, have you seen any waiver issues some of the other companies have expressed concern that a year or two out there might be some difficulty getting this product out and meeting some of the specs that the government's putting into the grants they're providing.
Amy
Paul, I didn't understand waiver issue. Could you be more specific?
Paul Essie
Well, labor issues with rolling out the installations. No, we have not heard that.
Amy
No, no, we have not heard that. We had those issues, I would say, in 2020 first half. And then 2022 have a little bit, 2021 people figured out how to work, 2022, no. I would not say we have heard labor issues at least for our products.
spk05
Okay. Well, thank you very much. That's all I had.
Amy
Thanks, Paul.
Paul
Thank you. One moment for our next question.
Operator
And our next question comes from Tim Savojo with Northland Capital Markets. Your line is open.
Tim Savojo
Hey, good afternoon and nice quarter. So I wanted to contrast a lot of these positives that you've been discussing in terms of PMP, six gigahertz, new products, 28 gig. I would imagine the fiber product would go in that bucket. some funding for customers from the government. So, you know, there's a lot of positives there. You appear to be guiding to very, very modest growth in PMP in 23, like, you know, low single digits maybe. And I know there's kind of some recovery maybe from a seasonal decline in Q1. But, you know, I guess how do we contrast, you know, are we seeing kind of a fall off, quicker than expected fall off of legacy products On the one hand, that's kind of short term. And then longer term, to get to your target, even if you assume Wi-Fi is slowing, I mean, in the next few years past 23, your growth rates kind of need to be, in PMPs, sort of need to be where your enterprise growth rate is now, 25%, 30%, something like that. Is that something you have confidence in or a line of sight to?
Amy
Yes. Tim, thank you for the question, an excellent question. Let me give you more insight into this. As I said earlier, I look for million-dollar deals because then I know the technologies are scaling. I think that's happening on 60 gigahertz. And even as we speak, some of the networks we are conceiving, even with 60 gigahertz, the numbers are now beginning to be 5,000 to 10,000 subscribers. So that gives us the confidence that these new platforms are now scaling, customers are deploying, and they're getting the confidence that they can truly provide fiber-like speed wirelessly. That's 60. 28 is driven by 5G standards, and I mentioned earlier, in 2026, the TAM of that market for fixed wireless is about 1.6 billion. And we have just started the 5G route. I think the contrast you will see between 60 and 28, 28, we are now, as I said, we have 20 POCs, eight in production, and customers are beginning to scale. The difference will be the deal size on 28 will be far larger. As I said earlier, over a three, four year period, five to 10 times the revenue total deal size because this is a license frequency. Somebody has paid money, they really want to deploy. But for fixed wireless broadband, life cycle is about four to five years. from the start to finish. So I think what we are describing is probably the first 20, 25th percentile in 23 and probably half of 24. And then these networks, this is what we have experienced the last 10 years. So we are sharing with you based on how we are seeing these technologies gestate. They have a really long life in that sense. So I think that gives us the confidence that As the gestation happens over the next three years, that 40-40-20, you know, PMP, enterprise, and PTP is very, very realistic. Because we know the market sizes. We know where our strengths are. We know where our sales teams and channels are. We have excellent channels, especially for PMP markets. And this is what we did last two years, you know, post-COVID, just focused on these next generation platforms. And now we are beginning to get the confidence they're scaling. That's the key word. They're scaling and they're being deployed. Fiber, while we are excited, fiber will go through the same thing. You know, our enterprise quarters used to be 2 million, 3 million, 4 million for first few years. It took us time to kind of learn, scale, deploy. And now we are cranking north of $25 million quarters. So that's what we do. Work with customers, closely with them, learn, and then scale.
Peter
And just to give you a little bit more color as well, that you're right, that there will be some level of seasonality in the first quarter with PMP and the revenues in PMP in the first half of the year when you look at it on a year-over-year basis will decline. But in the second half of the year, and this is how we define, getting back to how we define success, is that we'll be exiting the year with double-digit year-over-year and sequential quarter increases as a result of the new products coming into market in PMP. And that will continue, we believe, to accelerate into 2024. Thanks very much.
Tim Savojo
Sorry. Thanks very much. That was great, Colin.
Operator
Thank you. One moment for our next question. And our next question comes from George Nodder with Jefferies. Your line is open.
George Nodder
Hi, guys. Thanks very much. In the past, you guys have talked a little bit about what channel inventory looks like, whether it was kind of above or below average or average. Could you give us any comments on where you think that is right now?
Peter
Yeah, so when you break it down, I think that the channel inventory on the enterprise side is a little bit higher than what it's been running at over the course of the past 12 months or so. Some of that is because of improvements in supply chain and lead times getting a little bit shorter as well, and the ability to deliver product into the distributors. So I think that's what we're seeing on enterprise, slightly higher. On the PMP side, In terms of our inventory out at distributors, it's actually going the other direction. And that's a sign of the distributors getting ready for some of our new products as well. So, you know, I think it's somewhat balanced out in that fashion.
George Nodder
Got it. And then I guess I was also just going to ask you about supply chain. I think you kind of answered it there. I mean, are you still seeing any big holdups on supply chain golden screw type issues or Do you think, you know, products are flowing pretty freely now from a manufacturing perspective?
Amy
So, George, first of all, all manufacturing subcontractors and the sites are open and operating. As I said, supply chain is improving, but I don't think it's, you know, it's not yet normalcy. I think it'll be probably mid-23 when it'll reach kind of, for us at least, you know, mid-23, pre-COVID normalcy. There are still shortages on certain parts, but by and large, things have improved. And I think even after Chinese New Year, which is always something we watch carefully, this year, no hiccups. No hiccups. Factories are fully open. Logistics and freight are continually improving. So, so far, so good.
George Nodder
Great. Super. Thank you very much.
Amy
Thanks, George.
Operator
Thank you. And we have a follow-up question for Scott Searle with Roth Capital Partners. Your line is open.
Scott Searle
Hey, just a quick follow-up on the 6 gig front. I know you're looking at rolling a dual-mode 6 gigahertz solution product. I thought it was in the second quarter around CBRS, right? So it helps you circumvent some issues as it relates to reliability and bead funding. Just wanted to check on the progress of that and make sure that that's still tracking for the second quarter and kind of what the interest level is that you're seeing at least early on in dialogues with wireless ISPs and other carriers on that front. Thanks.
Amy
Yeah, so Scott, the combo product of 5 and 6 will very much be driven by the chip's availability. In the beginning, the 5 gigahertz and 6 gigahertz are two different products. And CBRS1 is a 3 gigahertz separate frequency, completely different product. So I think this year you will see us very much gain the experience and then focus on the combo side based on our experience with the customers and also based on availability of chips and all that. So I don't think the combo part will come right away because I think most of our customers right now are either deploying five or six. And CBRS is a completely different product.
Scott
Great. Thank you.
Amy
Thanks, Scott.
Operator
Thank you. And our next question comes from Timothy Horan with Oppenheimer. Your line is open.
Timothy Horan
Thanks, guys. So you have kind of five, six, I guess almost seven new major products kind of coming out here now. Can you talk a little bit about last time you had this many new services or certain new products coming out and what the impact was? And I mean, should we be kind of expecting material step up in growth in 24, 25, based on all the commentary that you have here? Thanks.
Amy
Thanks, Tim. Yeah, so while there are new products, if you look at when did we introduce them, a lot of it is about gestation. 60 gigahertz actually was introduced by us almost 18 months back. It's just that the gestation is now reaching a point where customers understand how to deploy. They are scaling. 28 gigahertz we introduced about a year back or so, something like that. And that is also beginning to now enter a point where they're going to scale. So I think when we say new products, while these are new platforms, some of them were introduced a year and a half back. The completely new stuff, which is coming now, is the 6 gigahertz, which we just introduced in Q4 last year, about three months back or so. These are different waves. I think the way to think about this is as customers are scaling the networks, they will not deploy all of them at the same time. They will deploy depending on the region, terrain, they'll deploy different frequency, and these will overlap over time. And that's what gives us resiliency. Because now we have different frequencies for different countries and regions. We have different performances and different cost structures. Like 28 is a license frequency. Only Tier 1s and Tier 2s can afford that, so we are now working with them. What the sixth is, a lot of WISPs will use 6 gigahertz. It's an extension of 5 gigahertz. And 60 gigahertz is going both in enterprise, as I explained, as well as municipalities and WISPs. So what you're seeing from Cambium is a broad wireless fabric serving some very key segments, and each one of them takes a little different time to gestate.
Timothy Horan
You know, I understand, but I mean, they're all kind of hitting the S curve of the adoption cycle, you know, in the next six to eight and the next six to 12 months. I mean, they're all hitting almost at the same time. And the same thing with the Wi-Fi products. It feels like, I know they've all been introduced at different times, but for a whole bunch of reasons, it does feel like we should really see a real acceleration in 24 and 25. And I'm not trying to put words in your mouth, but it does seem like they're all, you know, really hitting for 24.
Amy
Yeah, Tim, I agree with you. I think starting in the second half, you will see some of the acceleration as We mentioned 6 gigahertz, for example, but 24, 25, we will benefit from all these investments we have done in the last almost 18 months. That's an accurate statement.
Peter
Thank you. There are product cycles for the older products as well that just in terms of its life cycle will go the other direction as well. So just keep that in mind.
Timothy Horan
Do you have any – I know it's early to give guidance, but, I mean, all things being equal, it should be up from this year's growth rate. Is that pretty fair?
Peter
We really haven't gone through that level of guidance or analysis for 24 yet. But we are, like we said, we are excited about the new S-curves, especially when you look out over the next 12 months and you look at the 6 gigahertz product and the level of volume that that could mean in starting a new S-curve in the PMP side of the business.
Timothy Horan
And do we have any sense of the TAM of the 6 gigahertz product?
Amy
Yeah, I think the way, Tim, you want to think about this is 6 gigahertz is an extension of 5. And the 5 gigahertz point-to-multipoint was about a billion-dollar time. The way you want to think about this is that billion-dollar will churn and extend into the 6 gigahertz. That's probably the easiest way to think about it. Thank you.
