Our prepared remarks will be followed by a Q&A session. I'd now like to turn the call over to Atul.

Thank you, Peter. Cambium had recovery in our second quarter results with revenues of $69.3 million, increasing 12% sequentially, slightly ahead of our midpoint of between $65 million to $73 million announced during the Q1 '22 quarter call. Profitability improved significantly, with EPS of $0.18, ahead of our outlook of between $0.01 to $0.11, as we regained some scale, had higher gross margin, and spending was lower than anticipated due to our tight cost controls. Our technology roadmap and strategy continued to strengthen. Cambium is at the start of a new growth S-curve. During evolutionary change, performance starts from a slow initial phase, goes into an accelerated deployment phase, before stabilizing and maturing. This is about a five-year cycle for Cambium and the last time we entered this cycle was 2016. We are now at the cusp of entering the accelerated phase of growth for high-performance broadband networks. We anticipate continued recovery in revenues during the third quarter 2022, given our record backlog, pricing actions announced late last year are now fully in place, and we expect further improvements in the supply chain and distribution of components and finished products during the second half of 2022. We exited the second quarter 2022 with backlog up 5% quarter-over-quarter and higher by 29% year-over-year. We saw strong demand for our enterprise solutions, which grew 55% sequentially and increased 31% year-over-year, including record Wi-Fi 6 revenues. We now expect our enterprise business to grow over 45% for calendar year 2022. While the supply situation remains tight and challenging, we exited Q2 '22 with another record quarter of backlog for enterprise products. Cambium's attractive total cost of ownership and cloud-managed wireless fabric of solutions integrate multiple communication standards and emerging broadband technologies, which we are now calling Cambium 1 Network. Our solutions are a…

Thanks, Atul. Cambium had revenues of $69.3 million for Q2 '22. Revenues increased by 12% quarter-over-quarter and decreased 25% year-over-year. While revenue and global supply constraints are beginning to ease, we still had impact to shipments of our products during the first two months of the quarter as a result of the China COVID shutdown, although we continue to have significant pent-up demand, especially in our enterprise products. Our backlog and end demand remained strong, with backlog increasing by 5% quarter-over-quarter and 29% year-over-year. On a sequential basis for Q2 '22, revenues were higher by $7.4 million. The higher revenues were primarily the result of increased enterprise and PTP solutions, while PMP revenues were lower due to softer demand for legacy PMP 450 partly offset by improved supply benefitting ePMP shipments. Moving to our gross margin. Our non-GAAP gross margin of 48.9% was significantly better than anticipated, although decreasing by 110 basis points compared to Q2 '21. The year-over-year decline in our non-GAAP gross margin was the result of lower revenues, increased component costs, as well as higher freight and distribution costs due to expedited shipping. On a positive note, on a sequential basis, our non-GAAP gross margin improved by 110 basis points compared to Q1 '22. The higher quarter-over-quarter non-GAAP gross margin was the result of a higher mix of enterprise products, tight cost controls, and the benefit from the previously announced price increases that we instituted approximately three quarters ago. The higher gross margin is notable considering we had expedited shipping from the Shenzhen factory to distribution hubs in North America and EMEA in order to balance freight congestion and fuel surcharges as Shanghai unlocked from COVID. We believe we will continue to see sequential improvements to our gross margin during 2022 from both the benefits of the…

Cambium's growth strategy and drivers remain solid. We are now benefitting from increasing chip supplies, which will drive our growth during the second half of this year. Our investments in multigigabit wireless products such as enterprise Wi-Fi 6 and 6E, wireless savvy switching products, 60 gigahertz cnWave, 28 gigahertz millimeter wave solutions for fixed 5G, and the upcoming launch of 6 gigahertz fixed wireless solutions arriving later in 2022, will drive future revenue growth. Our federal business is at the start of significant growth, and we are now benefiting from our software-as-a-service solutions. The integrated wireless fabric, which we are now calling Cambium 1 Network, brings together ease of deployment, scalability of networks, and lower total cost of ownership as the world deploys next-generation high-performance wireless broadband. We remain focused on judiciously managing our costs, continuing to invest in innovative products to maintain our technology edge, and expect increased scale, and all of this will benefit our future operating results. I'd like to show my appreciation for our employees, partners, and customers during these unprecedented times. This concludes our prepared remarks. So, with that, I would like to turn the call over to Jason and begin the Q&A session.

Thank you. We will now begin the question-and-answer session. Our first question comes from Simon Leopold from Raymond James. Please go ahead.

Thanks for taking the question. I wanted to start off first, trying to get a better understanding of what you think is going to happen in your mix for the balance of the year. You walked us with the comment that you expected the Wi-Fi business to be up by 45% for the year, which is nice uptick. But you tend to have kind of lumpy quarters. And in particular, I'm looking at the PMP products being down sequentially two quarters in a row. Trying to figure out where that stabilizes. So ultimately, I'm looking for some sense of what you're thinking about for mix in the next couple of quarters and then I've got a follow-up.

Sure, yes, thanks for the question. So in terms of mix, we expect the enterprise business to continue to be strong and to continue as a percentage of our overall business to grow. In terms of PMP, we think that that will begin to stabilize late third quarter, early fourth quarter. We do think that there will be a continued downtick because of the product cycle that we're in. And the fourth quarter, keep in mind is when we're going to begin to see revenues from the new product introductions, and that should drive positive quarter-over-quarter results in the fourth quarter.

Yes, maybe one more point, Simon, I want to add is, we have entered the S-curve on enterprise probably about two quarters back or so. And we are now entering the acceleration phase. And if the supply continues, you'll see that. I think the S-curve on the fixed wireless broadband, we will start -- we're at the cusp of it. We'll start probably Q4 because Q4 is when we will introduce 6 gigahertz products. It's in beta test right now. And 28 gigahertz funnel is now also beginning to mature into deals. As we announced, we closed our first multimillion-dollar deal. So I think you will see -- and the PTP business actually is also beginning to accelerate well because of defense. And the PTP 700 is our bedrock for the defense business and there we're introducing new products like smart antenna in Q4. So, in general, you will see I think the fixed wireless broadband, which is a bedrock of Cambium with a lot of differentiation with significant installed base is ready to move to the new technologies and ready to ride the new S-curve. So we feel pretty good as we head towards '23 as you will see. And the way I always describe is Cambium has two wheels of a motorcycle. Both wheels -- sometimes one wheel might operate a little more efficiently, little more faster, but both wheels are going to be pretty important for our future.

Yes, and specifically, PTP in the third quarter, we're expecting a pretty good uptick because of the government business. And I think you'll see that come through in Q3.

Great, and then, as my follow-up, I'd like to get both the near-term as well as longer-term take on government stimulus programs RDOF, BEAD, how you see them contributing to the business, and I'd like to hear that both from sort of a current year view as well as the longer-term? Thank you.

Simon, let me take that question. I'll give you a good rundown on both RDOF and BEAD. Let me first touch upon RDOF. RDOF overall was, remember, $20 billion over the next 10 years or so. Out of $20 billion, $9 billion was promised, and then out of $9 billion, $4.5 billion was committed, mostly to fiber. You will see wireless awards coming through either late this year or early next year. That's our expectations that the wireless part of the funding -- and some of our customers are very much participating in that. I think Cambium will see first half '23 is my best guess right now. And when you look at the BEAD, which is a federal program, that's about $142 billion large fund. They are going through a mapping phase by FCC. It's called Broad Data Collection, BDC, project. Until all that mapping is done for the different communities and all that, there will be no funding release. So my guess is the BEAD, the federal side of things, probably end '23 or late '23, early '24 if I were to guess. And that gives you timing on both of them where we see things.

Great, thank you.

Thanks, Simon.

The next question comes from Samik Chatterjee from JPMorgan. Please go ahead.

Great, thanks for taking my question. The first one, I just wanted to see if you can comment on the linearity of revenues during the June quarter. I know a couple of months were impacted by the China COVID situation and things got better as you exited the quarter. But just trying to sort of see where the exit rate was in terms of shipment or revenue in the last month of the quarter and how it was heading into sort of 3Q time period? And I have a follow-up. Thank you.

Sure. So you're right. In terms of linearity, as a result of the COVID shutdown, things were pretty slow to gradually open up, especially when you look at the shipping situation and the freight shipping out of China and the backup that they had as a result of coming out of COVID. And that didn't really begin to recover until late May, early June. But despite that, we were still doing some shipping or some shipping by air, as I mentioned during my prepared remarks. And as a result, we were still able to get product out to customers during the first two months of the quarter. But certainly, I would say that linearity in terms of this quarter versus prior quarters was even a little bit more heavily weighted to that last month of the quarter. And we ended the quarter, as Atul mentioned and I mentioned as well, with a very, very strong backlog.

Okay. And if I can just clarify on that. Are you assuming any further supply disruptions in the third quarter?

I wouldn't say we're assuming any supply disruptions, but supply chain in general is still challenging, especially in our enterprise business where despite the fact that we're growing by more than 45% year-over-year is our expectation, we're still supply constrained. So we are still seeing pockets of areas within our supply chain that is still quite challenging. The freight situation is getting better, certainly, but there's just lumpiness. There's still lumpiness in where there's issues and where there's product availability.

And maybe one point I want to add is when we say this year we'll see 45% plus growth enterprise business, we have taken into account what we have. We have taken into account the commitments we have and all that. And if supply situation improves, that tells you that we could do better.

And Atul, just a question for you, which is more broader is, obviously, everyone is concerned about the macro here and you have the two legs that you talked about. How you're thinking about resilience of the top line in the event of sort of reasonable level of economic slowdown, particularly on the enterprise business side, where you're seeing strong growth right now?

From our vantage point, Samik, we see that the need for bandwidth, the need for connectivity, especially in enterprise, we are going over mid-enterprises, hospitality, education, managed service providers who are really providing very affordable Wi-Fi -- smart city Wi-Fi across the world. That is an unabated need. That need cannot be slowed down. And since we are going after mid-market enterprises, we don't anticipate a macro to really slow that down massively, at least on the enterprise side. Now on the fixed wireless broadband side, anyone who is depending on lot of government money, they could slow down. But lot of our customers are buying Cambium in the fixed wireless broadband side because of economics, solutions are economical, solutions are performant. So far, I'm not concerned about that.

Yes and keep in mind that we're gaining market share. So I think that's a very important element, especially on the enterprise side.

Yes, and like for example, on enterprise, we are at a very early cusp and customers are liking the economics, the ease of deployment in the mid-market segment. So we have a significant opportunity to emerge as a leader in that segment.

Got it, thank you. Thanks for taking my questions.

Thank you.

The next question comes from Rod Hall from Goldman Sachs. Please go ahead.

Hey guys, thanks for taking my question. This is Bala on for Rod. I guess I feel want to start off with the performance in the quarter. Clearly, Wi-Fi performance was better than you had expected three months back, and we see that in the margins also. Gross margins were better. On the contrary, PMP performance at $28 million revenues in the quarter is the lowest that I could see in the last five years for you. Clearly, demand is weak there. And I see your commentary like customers are taking a pause ahead of the new 28-gig product, et cetera. But maybe could you expand a bit more and kind of explain more why do you feel confident or maybe talk more in terms of visibility that you have? I see the number of POCs that you got. But still more tangibly do you have any backlog there? Or what generally gives you more confidence for that particular segment? And I got a follow-up.

So, Bala, couple of key points for explaining why we feel good. In the PMP business, the last time we entered the S-curve was with Medusa in 2016 timeframe or so. And the customer expectations at that time was maybe 25, 50-megabit per second type of throughputs. And we had a fantastic performing product, very economical, and we saw a lot of growth. I think that S-curve is over. The new S-curve is you need to deliver 100 to maybe in some markets, 200, 300 megabit per second. That needs band and frequencies, which are wider, less noisy, where you can really deliver that kind of performance. And hence, the 28 gigahertz 5G fixed product. We conceived that two years back. We knew that new S-curve will need that performance, and we are feeling very good about the funnel and the deal we are -- one of the deals we just closed is a sizable deal. And we have significant deals in the funnel, and you will see Cambium announce through press releases over the next probably three quarters fantastic deals in 28 gigahertz sizable. And the size of these deals in our last 10-year history we have not seen because these are Tier 1, large Tier 2 customers globally. So that gives us confidence that we have the next-generation product -- next-generation S-curve growth product. Secondly, the 6 gigahertz band, which we will start to release the products for full volume Q4, we are already beta-testing that with 10 customers. That gives that wider channel, honest-to-good gigabit performance. So overall, when we say new S-curve of growth, this is now five years are done. This is the next five years. And the last point I want to make is that the government money has not flown in, at least for wireless part. I think the first half '23, you'll start to see the PMP money come in, access for RDOF side, and I think late '23, early '24, you will see the BEAD money coming in. And Cambium's formula is very simple. We focus on affordability. We don't go after very high performance, very high end, and very expensive networks. We go after that strong, mid-tier, 80 percentile, and those are the products we have now. So we feel good where we are, where we are going, and you see both parts of our business accelerating the new S-curve.

I would just add one thing to that, too, in terms of PMP is that the channel inventory is down about 5% or so from what we can see, which is -- our comment about demand and working through the channel backlog is beginning to get more favorable as well.

And Bala, one more point. NTIA and the BEAD part of the program, they announced that CBRS 3.5 gigahertz will be treated as license frequency. This just came in last few weeks. So that basically means that the government funding will allow the CBRS 3 gigahertz to be treated at par with fiber. So you will see Cambium -- these are all changes happening as we speak. So I think we feel good about where we are, the kind of products we are, and the kind of innovations we have done, which gets us ready for this acceleration as the next growth curve comes in.

Got you. Very helpful. Thanks so much, Atul. And I got a follow-up. Full-year guidance, it's still pretty -- if I look at the guidance range for revenues, margins, et cetera, it is still pretty wide with only two quarters left. And it could be because, like you say, you do have pipeline in the near-term, but the transition to new products would probably cause some sort of turbulence in terms of customer adoption in the near term. Is that the reason why you are still maintaining a wider guidance because of that uncertainty for Q4?

Yes, I mean I would say that's part of it. I think when you look at the whole macroenvironment of supply chain overall and the tightness that I mentioned within the enterprise market, the availability of those specific chips that we need for our products, there's limited room from where we sit here right now for expansion. Now there may be some inventory that frees up in the secondary market. That's always possible. But we're forecasting based on what we know today, and we're forecasting based on what our commitments are to get those chips into our numbers, into our products that will result in sales and get into our numbers. So I think that while the range for the full-year is basically where we were last quarter, and we're one quarter later, I think it's appropriate given the overall macroenvironment.

Yes, that's fair. And finally, on backlog, you talked about significant backlog, but could you maybe quantify it for us? I assume most of it is probably in that enterprise Wi-Fi business. But could you just quantify it for us?

Yes, we're not going to quantify it exactly, but it is higher than what we had said where we were last quarter, as I mentioned by about 5%, even though last quarter, if you remember, we were in the midst of a China complete shutdown. So even with China lifting -- coming out of COVID and reopening, we're still higher than where we were last quarter. And you're right, a significant amount of that is in the enterprise portion of the market, but the PTP segment is also quite strong. Government segment is quite strong. And that's where we see there being benefit this quarter -- this third quarter as well as the fourth quarter. And keep in mind that when you look at the margins in the government business as well as Wi-Fi and enterprise, those tend to be stronger margins, and that further gives us confidence over our margin projections as well.

Got it, very helpful. Thanks so much.

Thanks, Bala.

The next question comes from Scott Searle from ROTH Capital. Please go ahead.

Hey, good afternoon. Thanks for taking my questions. And nice to see Wi-Fi is bouncing back towards record levels. Maybe if I could, digging in on the last question. The guidance for the year of $280 million to $300 million, given what you're guiding to for the third quarter, implies at the higher end for the fourth quarter, you could be looking at $90-plus million. I guess you've referred to this a couple of different ways in terms of strength of Wi-Fi, point-to-point and federal government coming back. But I'm wondering if you can go through what's your confidence level starting to look like going into the fourth quarter that you've left that guidance out there? Because it certainly implies that there's some good demand. I know you've got some new products. But how are you thinking about that? And as part of that, I'm not sure I heard a number in terms of the revenue that was left on the table due to supply constraints in the second quarter.

Yes, so, Scott, number one, supply chain is improving, and we are anticipating that Q4, it will give us even more leeway than Q3. So more optimism in terms of supply chain, chip positive will ease, and we are working very closely with our suppliers on a weekly basis, so we know what they're committing. But it's still work in progress. When people ask me, when do you expect some normalcy, I will always say '23 -- mid-23 some semblance of normalcy because the markets we are in, and you might see some availability in some chips, but the markets we are in, they are hot markets, with 5G or Wi-Fi 6, all these products. And when you look at calendar '22, the areas where -- especially as we're going towards Q4, we get lot of good feeling, good confidence is the new products. The 6 gigahertz comes in Q4. And as I said, lot of excitement around that within our WISP community as well as some of the verticals where they are waiting for this gigabit connectivity. So we feel good, new products -- 28 gigahertz is accelerating very well. And as I said, size of the deals are superior, Europe, CALA, Asia are leading the charge. We feel good. We have not seen this size deals in our history. PTP defense, the world has actually -- because of the Ukrainian war, many defense establishments are now converging because they want fast interoperability. That is driving our PTP 700 business. So there are many things converging and supply chain improving, that gives us a good feel for Q4. But net-net, the reason we still have the wider range is supply chain continues to be still an improving thing and work in progress.

Okay. Very helpful. I appreciate the color. And if I could, as a follow-up, on the 6 gigahertz front, huge opportunity there, both domestically and growing internationally given the amount of spectrum, given that you leverage existing Wi-Fi 6E infrastructure. So I'm wondering -- couple things. If you could kind of take us through the milestones, product will be available in the fourth quarter. How quickly does that ramp? What is the level of interest? And how quickly do we see this become a meaningful portion of the revenue stream? And I don't know if you have any early thoughts on that front in terms of how you're thinking about 2023? Thanks.

Okay. Good questions, Scott. The way we approach our point-to-multi-point, especially the ePMP line, is we very much focus on affordability. And the fact that the Wi-Fi 6 has gone to 6E, that gives us a very affordable cost-effective chipset to use where we do a lot of innovation in software and antennas. So it gives us a truly gigabit solution with fantastic affordability. And many service -- and this is for global markets. Many service providers will have no government dollars in many countries. So we are making sure that government dollars or no government dollars, Cambium subscription remains very affordable and very performant. That's kind of point #1. Point #2, these solutions will complement fiber. Many of our customers are going to be fiber customers because when it comes to terrains and the last mile, last two miles, they have ARPU challenges. Service providers have significant average revenue per user challenges in many geographies. So they want this type of solution for 60 gigahertz. We are in Q4, going to use the experimental license, which our customers will acquire. This is called STA, Special Temporary Authority, STA licenses. So under STA licenses, you will see Q4, Q1, Q2, lots of POCs across North America. And many countries are now watching what we do in North America and copy that. And FCC is evaluating, right now they're testing the AFC. So my anticipation is that the AFC approvals and all that will be done in first half '23, somewhere there, and the STA license will be used in Q4 to start the proof of concepts going. And this is basically a coordinated spectrum strategy and very innovative. So we feel good. We will be one of the first companies to produce volume quality product. And my anticipation is, as usual, two to three quarters will be lots of POCs, and then the ramp start probably second half of '23.

Perfect. Thanks so much. Appreciate the color and looking forward to the ramp.

Thank you.

The next question comes from Erik Suppiger from JMP Securities. Please go ahead.

Yes, thanks. Thanks for taking the question and great job on the enterprise. We haven't heard too much in terms of the macroeconomy slowing on your WISP customers or your end customers. What are you seeing in light of kind of an uncertain economy right now?

On the WISP side, there is no question that they all want to participate in these new government-funded projects, whether it's RDOF, whether it's BEAD money, but they also know that this could take time. As I said, RDOF for wireless is first half '23 because the dollars have gone to fiber right now so far, $4.5 billion, but there's a lot more money still to be allocated. So that's our anticipation. And also the very small WISP definitely are CapEx constrained. So there could be acquisitions there. There could be more consolidation happening there. But this is not the story everywhere. When you go to different countries, there's different dynamics. So my sense is that as government dollars come in, you'll see WISP adopt these next-generation technologies, 6 gigahertz, for example, and then other countries, 28 gigahertz is basically the key acceleration that is happening in many WISPs. In fact, there's a press release you will see by one of our customers called Pentanet in Australia in the City of Perth. And they're using 60 gigahertz to really deploy gigabit connectivity in Australia. So I think the new S-curve is starting, and that's what I said, 2016 we entered last time. I think 2022, late Q4, and then it's a five-year cycle. Probably a good solid one year in the early phase of S-curve, solid mid two years in acceleration, and then it enters maturity. So that's what we see a new S-curve starting probably late this year.

Okay. And then the number of the telcos, Verizon, T-Mobile, in particular have been really embracing fixed wireless access. How is that changing the competitive dynamics for you?

Actually, that's a good thing. Remember, fixed wireless broadband used to be afterthought. It was not mainstream. I think what 5G has done -- 5G and 28 gigahertz has legitimized fixed part of the broadband. But I'm very glad that Verizon and AT&Ts of the world are pushing it because their solutions might be very large-scale solutions or urban solutions. Our solutions are suburban, rural, in many cases, and economical. So overall, if the awareness of fixed wireless broadband increases, that benefits Cambium because we don't have those marketing dollars what they have. So I think net-net -- you will see another dynamic. Another dynamic is that many areas these large service providers may win a deal or they may get -- they may have a license or the government-funded project they might win, but they will subcontract or they will bring other service providers, which are smaller and for them that's a good enough business. And that's how these larger companies will participate. And these second-tier service providers will engage Cambium. So no matter how you see, when the water trickles down, Cambium will be a beneficiary in anything in fixed wireless broadband where affordability and quality is required.

Very good, thank you.

The next question comes from George Notter from Jefferies. Please go ahead.

Hey, thanks for taking our questions. This is Blake on for George. You mentioned that price increases have begun to work into the model. But you still have not felt the full impact from those, correct? And is there any specific segment where you've been able to pass along more price increases through?

So the price increases that we enacted last year are in our numbers -- pretty much fully in the numbers for Q3 at this point. If you remember, we didn't impact our backlog, and we worked through that backlog, at this point. So when you look at the Q3 -- if you look at the Q2 results and then what we're expecting in Q3, those include the price increases, and there still may be some that are going to trickle in, but it's really immaterial. So I think that's what you're seeing there. We certainly have experienced price increases on the cost side that has also offset the price increases that we've had and increases in components, in chips, in freight costs and all the things that we've spoken about. So net-net, that's the impact of the price increases from last year. And overall, what's really driving the increase in our gross margins is more mix, with the mix being more heavily weighted towards our enterprise products, which carry a higher gross profit margin by nature and by market. And that's really what's driving the increase much more so than price increases that were offset by cost increases.

Got it. That's helpful. And then I think you mentioned channel inventory was down 5%. Was that sequentially or year-on-year? And then do you expect channel inventory to kind of stabilize around these current levels or still work lower or...?

Yes, that's sequentially, and that was specifically in the PMP product line. And I think they'll probably continue to work down a bit as they're waiting for the new product introduction and waiting for that to happen. And I think that will happen in terms of stabilization in late Q3, early Q4.

Awesome, thank you very much.

Yes, thanks Blake.

The next question comes from Tim Savageaux from Northland Capital Markets. Please go ahead.

Hi, good afternoon. And I'm on little late, so forgive me if I repeat something here. But just want to focus on PMP from a couple of different perspectives. One, and I'm not sure what sort of guidance you gave about what's driving sequential growth next quarter. But should we be looking at Q2 as the trough for PMP revenues, I guess is the first question?

No, so we expect that there will be a further decline in PMP in Q3. And then we expect that it will begin to stabilize late Q3, early Q4. And then you'll see an uptick in Q4.

Okay, great. So Q3 is the trough or at least, I guess, we hope. In terms of the 28 gigahertz deals that were mentioned, I think you mentioned that was in the context of Q4, but they seem like they should be drivers for calendar '23. And you'd mentioned these deal sizes are pretty big relative to what you've seen in the past. I don't know if that's a PMP-specific comment. And you've booked some pretty big deals on the PTP side, on the federal side, including recently. I think you'd characterize those in maybe tens of millions type thing. Should we be thinking about these 28 gigahertz deals in a similar order of magnitude?

Let me give Tim a quick rundown on that. So 28 gigahertz, as I said, deal sizes are larger. And the reason for that is that these are larger service providers who have the money to buy licenses for 28 gigahertz. They have larger scale networks. So right off the gate, they want to monetize faster. And we have 10 POCs going in four continents. So we have closed one of them. One contract is done, and we are working now to close other deals. My sense is the needle will start to move probably '23 because this is still the early phase of that 28 gigahertz acceleration. But we will announce as we close these deals, from time to time, you will see through press releases. So I'm pretty pleased when we look at the size of the deal, and as I said earlier, these are pretty sizable deals. And the differentiation we are building in our product, 4x4 MU-MIMO, 400 megabit per second throughputs at scale, we're building some very good differentiations for these service providers. And we are also taking the service providers towards 5G. Remember, this is a 5G network. And we conceived these products two years back, and now they are coming out. So in terms of acceleration, I would say more '23. But in terms of contracts closing deals, we might announce as we close. And the fact that we are beginning to close contracts, that gives me confidence we have the right product, and this is really start of a new S-curve.

Well, just one more on that. So do you want to take a shot at quantifying the aggregate opportunity of those 10 POCs should they go to full deployment?

I wouldn't give a specific number, but you're not far off in terms of -- these deals are generally, Tim, four or five year long-range deals. They are rarely one-year contract. These are five-year contracts, four-year contracts. Almost all of them are long range. And those contracts will be -- you're not too far off when you say tens of millions of dollars.

All right. Sounds good. Last question on 6 gigahertz. And I guess my question is, does more need to happen from an operator, regulator, licensing standpoint, or from a Cambium-specific product standpoint to enable that ramp?

Excellent question, Tim. Very insightful question. From product point of view, we feel very good. As I said, we have approximately, I would say, close to 10 beta customers as we speak. So this is not something we are going to do. We are doing that right now. And in Q4, we will have ability to ship volume. This will be like production units and production software. And as I said, FCC's Special Temporary Authority, STA license is what will be used to get the POCs going. I think the more -- what is needed more probably over the next six months is for FCC to finish the evaluation and testing of the AFC algorithm, 6 gigahertz is a coordinated spectrum. And FCC has got a good experience from CBRS. CBRS is a tremendous success story for 3.5 gigahertz band. So I think what you're going to see is that when FCC testing is done, sometime in, I'm guessing, end of Q1, early Q2, somewhere there, this will all be allowed and operators want to see it operational because then they can start to make money for those high-performance networks. So I think a little more needs to be done by the service providers and the FCC working together to enable multigigabit networks, which are very affordable. And Cambium is ready. Cambium will be ready with AFC algorithm, Cambium will be ready with cloud management, Cambium will be ready with products. So from our side, we are ready in Q4. And we will be doing everything possible in our power to be educating FCC and pushing that launching. And they did a great job with CBRS and 3.5 gigahertz. So we're very confident. And AFC is not as sophisticated as CBRS algorithms were. So if they did a great job with CBRS on 3.5 gigahertz, I think they could do this in first half. So we feel pretty good.

Okay, thanks very much.

Thanks, Tim.
