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. We faced supply chain challenges within our industry, which impacted our first quarter results because of two unexpected events. First, a Chinese government COVID lockdown in Shenzhen impacted manufacturing during the middle of March. Second, during the last two weeks of the quarter, a lockdown in Shanghai closed our distribution and warehousing facility. Although our contract manufacturers have a global footprint, certain products and components are manufactured in China and cannot rapidly be relocated to facilities in different geos. Despite this setback, we are confident that once the supply chain recovers, we expect improved financial performance. We anticipate some recovery in revenues during the second quarter 2022, given our strong backlog and increased pricing actions now fully in place. We exited the first quarter 2022 with backlog up 7% quarter-over-quarter and higher by 10% year-over-year. Cambium's cost-effective multi-gigabit Wi-Fi and ePMP product lines were most affected by the lockdowns in China. Despite the lockdowns, we saw strong demand for our enterprise solutions and exited Q1 2022 with record backlog for Wi-Fi. During late Q1 2022, we began taking orders for our new quality of experience, QoE, subscription service, which provides visibility and network traffic optimization in real time to mitigate congestion and control network traffic. One customer, an Italian service provider, noticed immediate improvements, including a clear reduction in support center calls and actual reports of improved broadband performance. We are at the forefront of the next wave of high-performance wireless broadband technology, including our millimeter wave solutions. Our new 28 GHz, 5G multi-gigabit fixed wireless products shipped for revenue in limited quantities during the first quarter. We presently have 8 POCs for our 28 GHz cnWave going on in four continents, with three additional customers planning POCs pending receipt of equipment shipped in March. As we previously mentioned during our last earnings call, we expect larger deal sizes with 28 GHz cnWave. Cambium's attractive cost of ownership and cloud-managed wireless fabric solutions make our fixed wireless solutions a compelling choice for wireless infrastructure projects around the world. Turning to the results of first quarter 2022. Revenues of $61.9 million came in below the outlook of $77.5 million-$81.5 million announced during Q4 2021 earnings call. The supply-constrained environment affected shipments of both fixed wireless and Wi-Fi products during Q1 2022. The Wi-Fi market and ePMP product lines were most affected by Chinese government lockdowns in Shenzhen and Shanghai. Although demand remains very strong for our Wi-Fi, wireless-aware switching, and ePMP products. Looking at revenues across our different product lines. Our point-to-multipoint PMP business revenues decreased 16% sequentially and decreased 46% year-over-year due to global supply and distribution constraints negatively impacting shipments of ePMP products and slower demand from North American service providers. We are seeing the component shortages continue to improve, although gradually, and expect the lockdowns in China to loosen during Q2 2022. The point-to-point PTP business decreased 4% sequentially during Q1 2022, with component shortages limiting shipments of certain products. While year-over-year revenues decreased 16% due to lower shipments for backhaul products compared to a very strong prior year period. Our enterprise Wi-Fi business had revenues of $15.5 million, with revenues decreasing 40% sequentially due to supply and distribution disruptions, although higher by 28% year-over-year during Q1 2022. Demand remains very healthy for our enterprise Wi-Fi and wireless-aware switching solutions, and we continue to win larger and more diverse customers in this end market across the world as customers adopt our next generation leading edge Wi-Fi 6 and 6E solutions. Looking at some notable customer wins and new product developments. In North America, in Scottsdale, Arizona, a leading broadband service provider, Desert iNET, is extending fiber networks with Cambium 60 GHz cnWave fixed wireless broadband solution to deliver multi-gigabit access to residential subscribers with faster time to service than trenching fiber at a very attractive cost of ownership. Cambium's wireless fabric makes it easy to plan, deploy, and manage affordable gigabit speeds to the home and enterprise. An assisted living facility in New Jersey selected Cambium's Wi-Fi 6 access points, cnMatrix wireless-aware switches, and cnMaestro X cloud management to enable further efficiencies from digital transformation initiatives while minimizing total cost of ownership for the assisted living facility. Residents wanted the ability to connect with friends and family, and assisted living care operations managers needed reliable Wi-Fi at reasonable cost. In our defense business, we landed the first portion of a five-year contract from the U.S. federal government for Cambium's PTP 700 technology to upgrade global military-based security with high-capacity fixed wireless broadband communications infrastructure. The first phase of this program is mid-single-digit millions for Cambium, with the potential to be tens of millions of dollars. In the Europe, Middle East, and Africa region, EMEA, we continue to have healthy demand for our enterprise business and continue to win more and larger projects, although revenues were down due to COVID supply constraints from China. Recent strategic wins since our last call include in Northern Italy, we displaced a tier one enterprise networking supplier to deploy over 1,000 Wi-Fi 6 access points, wireless-aware switching, and cnMaestro X cloud management across 20 schools in the region. We won because of our wireless fabric end-to-end solution and Cambium's superior customer support. In South Africa, we had a fixed wireless win with Ikeja Wireless for our ePMP 3000 for residential broadband access across the country. We won as a result of strong performance versus the incumbent supplier. In APAC region, we received orders from two different service providers on both sides of the Australian continent for our first generation 28 GHz cnWave. In Korea, we had a Wi-Fi 6E win with our newly released high-density four-radio access point, the XV3-4 for Sangji University. In Caribbean and Latin America, CALA region, we had a win with a government service provider in Brazil, Prodepa, in the state of Pará. They selected our PMP-450 to provide internet access and communications to government buildings and schools. Cambium was selected for our superior performance and lower total cost of ownership for the customer. Turning to the new product introductions since our previous quarterly update. Before our next earnings call, we expect to announce the next expansion of our Wi-Fi 6 portfolio, including models specifically designed for the hospitality market and value-conscious buyers with availability during the second half of calendar 2022. At the higher end of the market, Cambium's new five-radio high-density Wi-Fi 6E access point announced in January will begin shipping this quarter. This solution targets high-density indoor applications such as auditoriums, meeting rooms, classrooms, libraries, and public venues. Cambium has the industry's first five-radio Wi-Fi 6E solution, which is much more efficient and cost-effective for high-density use cases. Our expertise and history with high-density Wi-Fi enable us to deliver a highly differentiated Wi-Fi 6E solution at a lower total cost of ownership than the competition. Cambium continues to build a strong foundation for our software and subscription services business, which delivers customer stickiness, recurring revenue, and accretive margin. Cambium has begun trialing in North America a new Network as a Service, NaaS solution. We are offering a package of cnMaestro X and Cambium Care combined with our Wi-Fi hardware made available as a subscription service. These subscription packages are billed monthly and are available in three- and five-year terms. Our initial POCs are performing well, and we are seeing strong interest in our commercial offering in Q2 2022. Looking at our cnMaestro Cloud software, our end-to-end cloud-powered connectivity solution to manage the network from a single pane of glass. The cnMaestro Cloud software continued to experience strong user growth. Total devices under cloud management in Q1 2022 were over 791,000, an increase of 6% from Q4 2021 and up 37% year-over-year. Turning to the channel. In Q1 2022, we expanded our channel presence by adding 70 net new channel partners sequentially and approximately 1,670 net new channel partners year- over- year, which represents an increase of approximately 1% sequentially and 17% year- over- year. During the first quarter, Cambium showcased our wireless fabric at the WISPAMERICA trade show in New Orleans. We received excellent customer feedback on our 60 GHz cnWave, 28 GHz cnWave, enterprise Wi-Fi 6 portfolio, and wireless-aware switching. Our upcoming 6 GHz EPMP solution is also generating lots of excitement for gigabit connectivity, particularly with North American service providers. Our technology and platforms, including the new software capabilities like QoE and cnHeat, were also well received by customers. I will now turn the call over to Andrew for a review of our Q1 2022 financial results and Q2 2022 outlook. Thanks, Atul, and hello, everyone. Cambium had revenues of $61.9 million for Q1 2022. Revenues decreased by 21% quarter-over-quarter and by 30% year-over-year. The global supply constraints, combined with the Chinese lockdowns, impacted shipments of our products, which continue to have significant pent-up demand. Our backlog and end demand remain strong, with backlog increasing by 7% quarter-over-quarter and 10% year-over-year. On a sequential basis for Q1 2022, revenues were lower by $16.8 million. The weaker revenues were primarily the result of the lower enterprise Wi-Fi solutions and point-to-multipoint revenues due to global supply constraints negatively impacting the manufacture and shipments of our products. Moving to our gross margin. non-GAAP gross margin of 47.8% decreased by 230 basis points compared to Q1 2021. The year-over-year decline in our non-GAAP gross margin was the result of lower revenues and increased component costs, as well as higher freight and distribution costs caused by expedited shipping. On a positive note, on a sequential basis, our non-GAAP gross margin improved by 360 basis points compared to Q4 2021. The higher quarter-over-quarter non-GAAP gross margin was the result of previously announced price increases and mix as we shipped a higher proportion of Wi-Fi and switching relative to fixed wireless products. We believe we will continue to see sequential improvements to gross margin during 2022 from both the benefits of the actions we've already taken and increased scale in our business as we progress through the full year. The full impact of the price increases will be realized during the second half of 2022. In Q1 2022, our non-GAAP gross profit dollars of $29.6 million decreased by $14.7 million compared to the prior year and were lower by $5.3 million sequentially, both due to lower volumes. Our longer-term goal remains an annual non-GAAP gross margin target of 51%-52%. Non-GAAP operating expenses comprised of research and development, sales and marketing, general and administrative, and depreciation and amortization in Q1 2022 decreased by approximately $200,000 when compared to Q1 2021 and stood at $28.6 million or 46.2% of revenues. Given the lower revenues, non-GAAP operating expenses were relatively flat compared to the prior year period. When compared to Q4 2021, our non-GAAP operating expenses decreased by approximately $500,000 during Q1 2022. Quarter-over-quarter sales and marketing decreased primarily because of lower variable compensation for salespeople due to the lower revenues, while R&D and G&A had modest increases due to higher wages and professional services. non-GAAP operating margin for Q1 2022 was 1.6%, down from 17.5% during Q1 2021 and 7.3% of revenues in Q4 2021. non-GAAP net income for Q1 2022 was $300,000 or $0.01 per diluted share, compared to $11.7 million or $0.41 per diluted share for Q1 2021, and non-GAAP net income of $4.4 million or $0.16 per diluted share for Q4 2021. The lower non-GAAP net income compared to both the prior year period and prior quarter's results was primarily due to the lower revenues impacting our gross profit dollars. Adjusted EBITDA for Q1 2022 was $1.9 million or 3.1% of revenues, compared to $16.5 million or 18.6% of revenues for Q1 2022, and compared to $6.7 million or 8.6% of revenues for Q4 2021. With the current supply constraints combined with the China lockdowns impacting shipments, we temporarily lost some of our operating leverage in our business, although we remain committed to driving our adjusted EBITDA to our target model of 18%-19% of revenues. Now moving to cash flow. Cash used in operating activities was $19.2 million for Q1 2022. The cash used in operating activities included a $12.1 million decrease in accounts payable, principally due to the timing of inventory payments and annual variable compensation of about $10.2 million related to incentive compensation earned during calendar 2021 and distributed in the first quarter of 2022. Q1 2022 cash used in operations compares to $7.6 million of net cash used in operating activities for the first quarter of 2021, and $5.6 million of net cash provided by operating activities for Q4 of 2021. Now turning to our balance sheet. Our cash totaled $38.4 million as of the end of Q1 2022, a decrease of $20.9 million from Q4 2021. As previously mentioned, the sequential decrease in cash primarily reflects a $12.1 million decrease in accounts payable, principally due to the timing of inventory payments and a payment for annual variable compensation of the $10.2 million that was just recently mentioned. Net inventories of $40.2 million in Q1 2022 increased by approximately $8.8 million year- over- year, while increasing by $6.4 million from Q4 2021. Inventories were higher sequentially because of an increase in finished goods due to the inability to ship products from the Shanghai warehouse and distribution center during the last two weeks of Q1 2022. While the supply chain remains an ongoing challenge, we are working to selectively increase our inventory positions during 2022. As of right now, the manufacturing facilities in Shenzhen are open and operating. Factories are now open for 95% of our products. Components are in decent supply, and we expect improvement during the balance of the year. We are moving some products from our manufacturing and distribution centers in China to our other distribution centers in North America and Europe until Shanghai is fully operational. In terms of logistics, we are shipping by air freight as much as we have to compensate for the Shanghai COVID lockdown. Once Shanghai is fully operational, we expect it could take an additional one to two weeks to completely normalize our distribution activities. In summary, the quarter did not play out as expected given the COVID lockdowns in China on top of an already challenging supply chain environment. We strive to become more predictable. Our price increases are now layering in with the benefit that we expect to happen in full by the second half of 2022. Our backlog remains strong, and we are at the start of new product cycles. Once the supply issues are resolved, we expect to regain scale, improve operational efficiency, and make significant progress towards achieving our long-term target operating model. Now moving to the second quarter and full year 2022 financial outlook. Considering our current visibility as of today, our Q2 2022 financial outlook is expected to be as follows. We expect revenues to be between $65 million and $73 million, non-GAAP gross margin between 47.5% and 48.5%, non-GAAP operating expenses of between $29.7 million and $30.7 million, and non-GAAP operating income between $1.2 million and $4.7 million. Interest expense net of approximately $700,000, and non-GAAP net income to be between $400,000 and $3.2 million, yielding net income per share of $0.01- $0.11 per fully diluted share. Adjusted EBITDA we expect to be between $2.2 million and $5.8 million, and adjusted EBITDA margin between 3.4% and 7.9%. We expect a non-GAAP effective income tax rate of approximately 18%-20% and 28.7 million weighted average diluted shares outstanding. Our cash requirements are expected to be as follows. We expect to pay down debt of $1.3 million, cash flow interest expense of approximately $300,000. We expect CapEx to be between $1.4 million and $1.6 million. Next, turning to the full year 2022 financial outlook. We expect revenues to be between $280 million and $300 million, decreasing approximately 10.7%-16.6%. We expect non-GAAP net income to be $8.1 million-$20.1 million, or $0.28-$0.70 per diluted share, and adjusted EBITDA margin of 6%-10.8%. I will now turn the call back to Atul for some closing remarks. Cambium's growth drivers remain intact. As we said on the last quarter's earnings call, we reiterate increasing chip supply during the second half of this year, and our growth strategy remains solid. We expect to see above-market returns from our investments in multi-gigabit wireless products, such as enterprise Wi-Fi 6 and 6E, wireless-aware switching products, 60 GHz cnWave, our new 28 GHz millimeter wave solutions for fixed 5G, the new 6 GHz fixed wireless solutions arriving later in 2022, a reinvigorated federal business, as well as our software as a service solutions. The integrated wireless fabric from Cambium 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 should benefit our future operating results. I would like to show my appreciation for our employees, partners, and customers during these unprecedented times. This concludes our prepared remarks. With that, I would like to turn the call over to Delphin for beginning the Q&A session. Thank you. Once again, that's our CEO and President, Mr. Atul Bhatnagar. We will now open the call for your questions, and I would like to remind everyone, please limit yourself to one question and one follow-up question. Our first question is with Simon Leopold of Raymond James. Thanks for taking the question. I guess I was a little bit surprised that the gross margin was actually better than I expected. You know, several hundred basis points better and sequential improvement. So I'm just trying to make sure I get a grounding in terms of how to think about modeling. So I'm looking for maybe a little bit color in terms of if you could rank order your segments in terms of kind of the gross margin contributions and the supply chain impact, just to help us understand what the trends are in gross margin. Then I've got a follow-up. Yeah. Hi, this is Andrew. When you look at the gross margin versus last quarter, as you mentioned, it was up, which was great news. There's really two major factors that are causing that increase. One is the product mix. As Atul mentioned, our Wi-Fi products, despite the issues that we had with the China lockdowns, we're still up year-over-year and also very healthy, just given that situation on a quarter-to-quarter basis. In terms of the percentage mix versus the other products, the Wi-Fi was a higher portion of that mix. The second reason is the price increases that we had that we've mentioned before, where we had price increases last year that's working its way through the system. We expect that to see the full benefit of that in the second half of the year, but it started to impact our numbers in the first quarter favorably. Thank you for that. I wanted to follow up on the particularly the 28 GHz product. You did mention a large award in Italy, and I'm guessing and presuming that this product is playing into that award. Ultimately, what I'm trying to get a sense of is how to think about the size of that product's contribution as it ramps over time and the materiality or opportunity for 28 GHz platforms. Thank you. Thanks, Simon. This is Atul. I'll take that one. Let me give you a little more color around 28 because I'm very excited about the potential of 28 for probably next four to five years with what we are releasing right now. The way 28 GHz solutions are different, they are addressing larger service providers in Europe, South America, North America, and Asia, in that sequence, in that priority order. It's a licensed frequency. The service providers are going after many square miles of area and fortifying the territory with that licensed broadband solution. What we see is if you had X amount of total dollars spent by a service provider for, say, sub-5 GHz solution, traditional solution for a WISP or a medium-sized service provider, 28 GHz solution is probably 2x-3x the deal size. I think in next 12 months, you're gonna see us announce many larger Tier 2 and Tier 1 service providers with substantial business. It is changing our own dynamics. In return, Cambium is scaling the support structure because when you engage these type of service providers, you really have to have 24/7 across the globe, support teams, and that's what we'll be offering. Pretty excited. Just to give you an idea, I think we did mention the earnings call script, about 10 POCs, eight of them I think going and a two or three coming through. These are all pretty sizable customers. Very positive, very exciting, and this opens the runway to Cambium Networks towards 5G fixed. This is when we say next generation architecture, 28 is a very key plank of the next generation architecture. Maybe just to put some quantification around that opportunity, if we think about 2023 when we're past supply chain constraints, hopefully, could you see these products being on the order of 20%, say, of PMP? Is that just too ambitious a goal? No, I think you are not too far off. Great. That is, to be very frank, for me, the pleasant surprise is, as I gave you indication, if we did X amount of revenue for traditional products, I think we might be looking at 2x-3x because these service providers are going after larger area, and they have larger subscriber base to cater to. Thanks for answering that. Appreciate it. Thanks, Simon. Thank you. Our next question is with Rod Hall from Goldman Sachs. Hi, thanks for taking my question. This is Bala on for Rod. Looking at full year guidance, I'm just wondering what is being baked in into the full year guidance with respect to your operations in Shenzhen and also in Shanghai. It looks like Shenzhen is more or less fully operational now, but maybe just double-click on what you're expecting. How do you see the ramp as we go through the year? Then I got a follow-up. Yeah, thanks for the question. This is Andrew. You know, in terms of looking at the $280 million-$300 million that we mentioned for the outlook for the year, we were being prudent in terms of looking at what's happened in China and what the current status and the current situation is. We do believe that revenues will continue to increase as we go throughout the year, and we think that the second quarter revenues will be higher than the first quarter as well. We still just given the manufacturing distribution facilities that we have in China, we wanna be very careful in terms of looking at the outlook going forward and the impact of COVID, which obviously is very hard to predict. We're trying to really have a very balanced view and to be prudent in terms of what we believe the full year to be. As you saw in the numbers, and we discussed our strong backlog as well. The total backlog that we have today is as high as it's been in the recent past, or even higher than it's been in the recent past. Especially as we look at the Wi-Fi product line, that continues to be very favorable. That's what gives us that confidence that we'll get into that range, despite the situation over in China and the supply chain constraints. Right. If you look at the second half of the year, the new guidance compared to the previous guidance indicates maybe about a 15%-20% cut in the new guidance for the second half of the year. I assume this, as Andrew prudently assumes that, whatever, you know, lockdown-related supply issues that you are seeing would extend well beyond Q2 and then possibly throughout the year. Is that the right thinking there? Well, I think the first half of the year is really what's taking the largest hit. When you think about Q1 and Q2, those two quarters are quite a bit below what we had originally anticipated for the year. We do believe that Q3 and Q4 will continue to ramp up. We're getting better visibility now in terms of supply chain and chips, which is very good news, and that's consistent with what we had predicted back. Well, I wasn't here yet, when the company spoke back in February. That, in fact, is coming true. The setback that we had given the China lockdowns is what's really hurt in the first half, the first quarter, and we expect the second quarter of the year. We certainly do hope that Shanghai does reopen soon. There's some glimmer of hope that we've received as recently as today that could happen in the next couple of weeks, if not sooner. As I said, we wanna be prudent in terms of how we're thinking about it and have a balanced approach. I do think by the second half of the year, especially in the fourth quarter, we will see things beginning to return to somewhat of a normal situation and we will continue to have acceleration in certain areas of the business, such as Wi-Fi, as we mentioned. Yeah, Bala, if I can just add one comment. I think we have taken very proactive steps for the second half of 2022, working very closely with our chip partners, supply chain partners, and I think as we said in last quarter's earnings call, we expect second half to be increasingly better. Whether it's chip availability, whether it's supply chain partners, that's kinda what we see right now. We are baking that in. I think my sense is that, you know, cautiously very optimistic as we go into second half. Yeah. One other thing I would add to that is that even as we sit here today, you know, we're not waiting for Shanghai to reopen. We have a plan that we've started to enact. As I mentioned during my opening comments of shipping products out of the Shanghai region or directly out of the manufacturing areas in Shenzhen and elsewhere to other distribution facilities in Europe and in North America. That may cause some additional shipping costs that we will incur as a result of that. Even despite that, we think that with the favorable mix with Wi-Fi becoming a bigger part of the business, that will help offset those incremental costs and hitting the margin. Great. Thank you. Sure. Thank you. Our next question is with Samik Chatterjee of JP Morgan. Hi. Thanks for taking my questions. I have a couple, and for the first one, I actually wanted to follow up on Bala's question there with ask you in terms of what you think the exit revenue run rate for Q4 looks like, because I'm trying to compare it to June 2021 quarter, where you did about $93 million of revenue. From everything sort of you've talked about today, it doesn't look like you're suggesting demand is a problem, it's more either logistics or supply. I'm wondering with sort of the supply situation that's now recovering with pent-up demand, like, what's holding back the Q4 exit revenue run rate to be higher than the sort of June number that you had, particularly your guidance for the full year. To me, it implies you're sort of thinking more mid-$80s million versus the $90+ million run rate that you've exhibited in the past. I have a follow-up as well. Thank you. Yeah. I think that's about right. We do expect around the mid-$80s million in terms of the fourth quarter, as you mentioned. Again, you know, we're being prudent in terms of how we're looking at where we think we're gonna be for the balance of the year. That, even at the mid-$80s million, is an acceleration from where we are today, certainly, and where we expect to be in Q3, which is, you know, in the likely mid-$70s million range or so. There's still a sizable increase in Q4, but we didn't really wanna get overly aggressive in terms of that outlook of Q4 given the situation with China and how they're treating COVID and the lockdowns for, you know, any sorts of cases of COVID that come up in the country and what's happening in China with their vaccine, etc. We wanna be prudent and estimate, when we look out over the next few quarters the best that we can. That's where we ended up. Also, Samik, Atul here. While things are improving, the normalcy will, I think, only come in 2023. So the needs of the Cambium emerging product lines, high-growth product lines, I think, you know, it'll be improving, but what we really need to go like a rocket, I think that's 2023. So that's what you see built in here based on our experience realistically where it go. As I said, we have taken a lot of proactive steps. We have given 20-month forecast to our chip suppliers. We are making sure test capacity in our manufacturing lines are ready for higher volumes. So, you know, these are also the times when companies need to do proper planning for expansion, and that's what we are focusing on right now. For my follow-up, Atul, I mean, I don't have the exact absolute number in terms of backlog that you guys are reporting, but just directionally looking at the quarter-over-quarter growth numbers here, you said a 7% quarter-over-quarter increase in backlog. It's very similar to what you had in 4Q as well. Given that you had the issues around shipping in 1Q, I would have expected a bigger increase in the backlog, unless I'm thinking about it wrong. Maybe just directionally set me right there in terms of why doesn't backlog have a bigger sort of number on it despite not being able to ship a lot in 1Q. Yeah. The backlog actually has continued to increase throughout this quarter that we're in. As I mentioned, we have the highest backlog today than we've had in the near recent past here. When you look at where our strength is in the business right now, in the Wi-Fi product especially, and the margins associated with that, we think that is gonna continue to grow and we've seen good acceleration of that this quarter. In terms of looking at the outlook both for Q2 as well as Q3 and Q4, that all takes into consideration where we ended up at the end of the first quarter and what the mix was and what the total backlog was at that time. As Atul mentioned, we have products that we're introducing into the marketplace that we believe will be very beneficial to our revenue outlook, especially go towards the last half of this year and going into next year. That's where I think, given as long as we see normalcy returning to the supply chain, we'll see continued acceleration of both backlog as well as revenues that you'll see showing up in the financials. Samik, Atul here. Two or three points I wanna make. Number one, I think as we go into the second half, the supply chain situation is getting better. And we said that last quarter as well, and I'm reiterating that. Secondly, the enterprise segment of Cambium is fully transitioning to Wi-Fi 6. Remember, these are S-curves of growth. We are on a new S-curve with our enterprise full portfolio, fully mature, full roadmap, very well- received. Next point is fixed wireless broadband is also going through a technology transition, and this is an important point, and we anticipated that with 60 GHz and 28 GHz. Both of those product lines are in early gestation. As we come through Q3, Q4, and then Q1 next year, you will see us talk a lot more about the wins, the deal sizes, because we see that new S-curve for gigabit networks and wireless coming and really augmenting fiber. The transition of fixed wireless broadband is probably about six months behind Wi-Fi. Wi-Fi transition happened faster but it's also simpler, and right behind the fixed wireless broadband transition, and I'm very excited. Cambium will beta test 6 GHz band for multi-gigabit connectivity on PMP line and ship volume in Q4. This is new, very advanced technology, and this will usher the new S-curve of fixed wireless broadband. Thank you. Thank you both. Thanks, Samik. Thank you. Our next question is with Mr. George of Jefferies. Please go ahead. Hi, guys. Thanks very much. In the past, you guys have given us some commentary on channel inventory levels. I guess I was just curious if you have some comments about where channel inventories, you know, stood at the end of Q1. George, good to hear from you. Let me take that question. In fixed wireless broadband, there's definitely assimilation going on of accelerated buying in, say, second half 2020 and then 2021, and we see that. The point of sale is. We monitor that pretty closely. I think in some products, there might be inventories because customers are kinda digesting, assimilating. Also, customers are beginning to think about what is the next generation fixed wireless broadband architecture. I think those are the two key drivers we see in terms of the inventory. When it comes to the enterprise products, they can, whatever we can give them, you know, they're grabbing right now. Thank you. I think over the next few quarters we will know a steady state wise where things land. In general, there is still, I would say, overall a good balance of where the inventory, inventories are, what the demand is, and in certain products, they are kinda still being assimilated in the field. Anything, Andrew, you want to add? No, I think you covered it well. Okay. Got it. I guess I'm inferring then that there's some products where channel inventories came out higher at the end of the quarter. I presume we're talking about fixed wireless access products, point-to-multipoint products. Yeah, it's possible. Maybe other products which are lower, so Wi-Fi. Yeah, it's possible. I think, George, in our industry, what ends up happening is as customers are conceiving the next set of frequencies. Remember, if you are a service provider and you're conceiving on 60 GHz, you might have some frequencies which are sub-six, and as you're shifting to 60 GHz or you're shifting to 28 GHz, and all of that gets taken care of, you know, over two to three quarters. net-net, at this point, we are still for a lot of our key product lines, we are still building our inventory. Like for example, ePMP product lines, we are very constrained in inventory right now. If we had more chips right now, we'll be cranking more products. A little bit of balancing act goes in, but net-net, customers are able to handle that over a quarter or two period. Gotcha. I also wanna ask about pricing. It sounds like you took pricing increases in Q4. I'm just curious, could you remind us how much those pricing increases were and then you know, how much of that might have been assimilated into the model in Q1? Approximately, and Andrew can please add based on anything I miss. Approximately, I would say 10%-15% price increase cumulatively across product lines based on some of the increases of prices we faced from our suppliers. Overall, we did have inventory and existing contracts. I would say Q2 is probably the first quarter where you'll see pretty whole impact. Mm-hmm. In second half, clean, because we would have eaten into those inventories and contracts and all that. It'll be all new pricing. Got it. Yeah. Okay. Great. Thank you very much. Thanks, George. Thank you. Ladies and gentlemen, once again, to ask a question, you will need to press star one on your telephone keypad. Again, simply press star one. Please limit yourself to one question and one follow-up question. Our next question is with Scott Searle from Roth Capital Partners. Hey, good afternoon. Thanks for taking my questions. Hey, Atul, I apologize for going back to the supply chain again, but it looks like you've been doing things in terms of best job that you can, struggling where everyone else has from a supply chain perspective, redesigning products. I was wondering if you could talk a little bit about more manufacturing, diversity of that manufacturing from a geographic standpoint, how you could be more resilient, you know, to not have any single points of failure going forward. Over the last three quarters, we've had some problems on that front caused by China. What can you do to design around that so you're a little more flexible, you know, if there's a third wave? Yeah. Scott, good to hear from you, and an excellent question. There are two areas we are working very proactively. One is linearity. In fact, you didn't ask that, but I'm gonna address that. We are working very proactively on linearity because we also realize that I think when you are more back-loaded, you also get hit harder with these type of events. Andrew, one of the reasons we brought Andrew into the company is Andrew brings excellent background with some of the manufacturing companies he worked for and linearity in those areas. That's one project we have started. Secondly, with respect to China and dependency on China, about, I would say maybe half of our manufacturing or so happens in Guadalajara with Flex. We are already, you know, we have a very strong relationship with them, and many of our fixed wireless broadband products are done there. In addition, we are very proactively diversifying from our ODMs in Taiwan into Southeast Asia, proactively, areas like Penang. You will see Cambium continue to diversify opportunistically and strategically. Having said that, there are a lot of components, power supplies, mechanicals, they come out of China. It's not just manufacturing. We have to look at it pretty holistically, in a 360-degree way, and we are going through all that. A lot of attention being paid because we totally realize that the more diversified, but in a meaningful manner we are, the better it is. Both projects getting a lot of good attention inside. You know, over the next few quarters, as we make those decisions, as we diversify, just to give you an idea, our new products we are designing, we are increasingly moving them towards Southeast Asia. Okay. Very helpful. If I could then follow up on the gross margin front, sounds like the price increases, you see more of an impact in the second quarter. You benefited from the Wi-Fi mix in the first quarter. If I kinda work through some of the numbers in the annual guidance, it either implies that OpEx is ramping up a lot more, or gross margins are kinda plateauing, if not sort of rolling over. I'm wondering, is there something else going on in the second half of the year as you think about the gross margin profile? Does it stagnate? Does it not continue to increase? Is it just level of conservatism in terms of how you're guiding? We're again being prudent on taking a look at where we are with OpEx as well as gross margin as we go throughout the year. The way that we're looking at it is that OpEx will increase a bit as we move ahead throughout the year because of inflationary pressures and increased salaries, for example, and costs relating to some of the R&D materials that we need in terms of the next-gen products that we are very much focused on. In terms of the gross margin, you know, we still believe very strongly in our overall operating model goal to work up towards that 51%-52% goal over time. We don't necessarily see that happening in the very short term, because of all of the issues around the tightening of the supply chain, as well as pricing of components and chips. I think once things begin to stabilize further and there's more supply of chips in the marketplace, that should happen towards the end of this year and certainly next year. I think that you'll see the gross margin increase further. Hopefully that answers your question. No, very helpful. By the way, congratulations. Welcome aboard. Andrew, if I could follow up on that front, is that 51%-52% a realistic goal for 2023? I think we could hit that goal, especially in the last half of 2023, driven by our new products, along with a normalization of the supply chain. Okay. Yeah. Maybe, Scott, one more point I wanna add is we have a very strong federal defense funnel right now. Mm-hmm. Never has been this strong, and the geopolitical events actually are driving that even stronger. I think you can expect that in second half of this year and in 2023, the federal defense will also play a key part. Generally, that gives us a good uplift for the gross margin. Okay. Yeah. I will say that as we look to diversify as well out of China, that there will be a cost of doing that, and that's why we're being, you know, really prudent in how we're looking at gross margins going forward. Yeah. I'd be looking at that towards the end of next year. Okay. Lastly, if I could just throw out three quick questions on the product front. Atul, you're talking about the excitement related to 5G at 28 G, the 60 GHz products. You've got multiple POCs for the 28 G. Could you help us understand, you talk about them being larger opportunities, could you put a number or framework around it, either what you would expect revenue to be exiting this year, or maybe, you know, what the revenue opportunity for them is in 2023? Also, on the ePMP front, I know that there's some new products coming that offer some higher, possibly multi-gigabit speeds, I think around more of the 5G architecture. I was wondering if you could talk about that. Sure. Lastly, I just wanna confirm the availability of the Wi-Fi 6E outdoor solutions, when we'll see them getting certification and then roll into market? Thanks. Okay. Thanks, Scott. One of the power or strength of Cambium is that we have a wireless fabric, and I'm gonna go a little deeper into that just to position that. Each region has a different frequency plan. Each region has a different dynamic. For example, in Europe and CALA, South America, they have 28 GHz licensed frequency with so many different service providers. We are seeing acceleration in 28 GHz there, very well- received. As I said, deal sizes are larger, and these deal sizes are, you know, multi-million dollar each type of a deal. I won't go deeper than that, but it can start to give you a flavor. When it comes to North America, the 6 GHz band is the excitement. This is clean frequency. This is 1.2 GHz, 1.3 GHz of band, which is being released for the first time in two decades. You're gonna see a significant solutions for multi-gigabit based on that frequency band. Cambium will be one of the first in the world to offer beta in Q3 and volume shipment. This is what I call new S-curve in fixed wireless broadband we're gonna ride. Our strategy is based on two keywords, affordability and quality. That's how we build this company. Always maintain the affordability, but yet have fantastic quality. You'll see us offer that in the fixed wireless broadband in North America. Overall, the fabric integrates the different frequencies and different architectures, manages from single pane of glass, and then tell the customers that, "Mr. C ustomer, the last edge, 0.5 km or so, you have indoor-outdoor Wi-Fi, which is Wi-Fi 6." That's why in many of these calls I say the combination of technologies like 60 GHz and Wi-Fi 6 is a hand and a glove. We are seeing that in municipalities, we are seeing that in educational institutions, we are seeing that in so many different situations where they use fixed wireless broadband, now they're using Wi-Fi. In some, they went with Wi-Fi and now they're saying, "Can you do metrics with 60 GHz?" Interplay of this multi-gigabit technology is very powerful, and you'll see that, I think, definitely in second half as well as in 2023. Great. Thanks so much. Thanks, Scott. Thank you. There are no more questions on the queue. With that, I would like to turn the call over to Mr. Peter Schuman for the closing statement. Thank you, Delfin.
