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. Demand and backlog remains strong due to the continued need for expansion of broadband wireless communications networks and a strong rebound in enterprise Wi-Fi shipments. We experienced an incremental improvement with supply chain challenges and are winning more sizable enterprise deals while taking market share during Q4 '21. For calendar year 2021, our enterprise business grew 67% well ahead of our original forecasts of 40% to 60% growth announced during our Q4 '20 financial results conference call last February. We achieved our overall results without the full benefits of the price increases and surcharges, which continue to layer into our financial results over the next few quarters. We are still facing supply chain challenges within our industry, although things seem to have bottomed and are expected to improve incrementally over the next few quarters as we have adjusted to the new normal which includes expedite fees, extended lead times as well as increased freight expenses. Demand remains strong. We exited the fourth quarter 2021 with backlog of 7% quarter-over-quarter and 16% year-over-year. We are at the forefront of the next wave of high performance wireless broadband technology with our millimeter wave solutions. Our new 28 GHz 5G multi-gigabit fixed wireless products are expected to be released during the first quarter. We presently have eight POCs for our 28 GHz cnWave wave going on in four continents. Our 60 GHz cnWave products are changing the way, fixed wireless is viewed by customers and expands our serviceable available market, bringing a standard based multi-gigabit fixed wireless solution using licensed and unlicensed spectrum to network operators serving residential, urban and enterprise markets. Cambium’s Enterprise Solutions bring sophisticated cost effective multi-gigabit Wi-Fi, wireless savvy switching, premium software solutions and subscription services to our customers, and the results have been outstanding during 2021. We had a breakthrough quarter for the Wi-Fi business with record revenues of $25.8 million, which grew 140% sequentially, and 136% year-over-year during Q4 '21. To put this in perspective, Wi-Fi represented a third of company revenues during the fourth quarter 2021, the previous record was 20% of revenues during the second quarter 2021. We are winning as a result of Cambium's attractive cost of ownership, which makes our fixed wireless solutions a compelling choice for wireless infrastructure projects around the world. With increased government spending on infrastructure projects, accelerating over the next few years, and our commitment to deliver cost effective and scalable multi-gigabit solutions to local communities and distributed enterprises around the globe, Cambium will be a winner over the next several years with its cloud managed wireless fabric solutions, extending from few meters to over 100 kilometers all done wirelessly. Turning to the results of the fourth quarter 2021, revenue of $78.7 million came in above the outlook of $73.5 million to $77.5 million announced during the Q3 '21 earnings call. The supply constrained environment mainly affected shipments of fixed wireless products and limited further upside to our fourth quarter results. The enterprise market had a strong rebound in Q4 '21, as supply constraints begin to ease. We were able to opportunistically purchase chips on the secondary market at higher prices. Non-GAAP fully diluted EPS of $0.16 was within the outlook announced during the Q3 '21 earnings call of between $0.11 and $0.17 per diluted share. Looking at revenues across our different product lines, our Point-to-Multi-Point (PMP) business revenues decreased 26% sequentially and 31% year-over-year due to global supply constraints negatively impacting shipment of products. We continued to see strong momentum in network traffic, increased demand for CBRS solutions and broadening interest in our new product introductions. We expect the component shortages to continue to improve also gradually during the first half of calendar year 2020. The Point-to-Point (NYSE:PTP) business improved by 10% sequentially during Q4 '21 with component shortages limiting shipments of certain products. Although we had higher shipments for Federal products, while year-over-year revenues decreased 9% due to lower shipments for backhaul products compared to a very strong prior year period. Our enterprise Wi-Fi business had a breakthrough quarter with record revenues of $25.8 million. Our previous record for Wi-Fi was $18.3 million during Q2 '21. We were fortunate to have improved supply conditions and pent up demand, with Wi-Fi increasing 140% sequentially and higher by 136% year-over-year during Q4 '21, although supply constraints remain. This is an indication of the strong potential of the Wi-Fi business for Cambium Networks. Demand remains very healthy for our enterprise Wi-Fi and wireless savvy switching solutions, and we continue to win larger and more diverse customers in this end market all over the world as customers adopt our next generation leading edge Wi-Fi 6 and 6E solutions. For the full year 2021 revenues up $335.9 million increased 21% from 2020. The 2021 growth was primarily driven by our Point-to-Multi-Point and enterprise Wi-Fi solutions, which both grew double-digit percentages over the previous year. For the full year 2021, our PMP products grew 19% and enterprise Wi-Fi grew 67%, while the Point-to-Point products increased 1% compared to calendar year 2020. Looking at some notable customer wins and new product developments. In North America, we had several competitive wins aided by government funding. A service provider in Texas ripped and replaced a competitive gear with Cambium's PMP 450m technology. A second service provider with a new focus on fixed wireless in rural Western New York State replaced Huawei equipment with Cambium’s PMP 450 with the aid of government funding. Within our industrial customer base, a North American railroad operator selected our PTP820 for its range, throughput performance, small footprint and superior reliability. Also in the transportation space, Buckeye Mountain, a leading system integrator of communication solutions to the railroad and intermodal industries has integrated Cambium Network’s fixed wireless and outdoor Wi-Fi technology into the rapid deploy family of connectivity solutions. As ports and rail yards deal with unprecedented supply chain issues, communications reliability is vitally important. We also see 60 GHz cnWave as an emerging application at railyards and railways for communications across rail tracks to avoid trenching fiber to cross railroad tracks. We had one of our first Wi-Fi 6E wins with a university in Texas. Not only did the select over 1000 Cambium access points to cover the indoor and outdoor areas of the classrooms and dorms, but they selected our ultra high density radios for the auditorium and public areas. They also chose our 60 GHz cnWave to backhaul the Wi-Fi for their stadium areas. Cambium first mover status for the FCC's 3.5 GHz CBRS spectrum continues to benefit our PMP 450 products and our CBRS SaaS service in both the U.S. and its territories. As of today's call, we now have over 129,000 devices managed by our CBRS SaaS service, an increase of over 12% since we reported last quarter, and an increase of approximately 93% year-over-year. In the Europe, Middle East and Africa region EMEA, recent strategic wins since our last call include: In France, one of the largest restaurant chains in the country, servicing 600 various quick service restaurants selected Cambium's Wi-Fi 6 and switching. The deal is a sizable one and we beat our several larger competitors. Our Wi-Fi performance superiority is propelling us forward in competitive wins. We have several wins in the enterprise hospitality vertical in Germany and Italy. These resorts in the northern hemisphere are upgrading their Wi-Fi for their guestrooms and convention areas during the off peak season. Cambium’s quality, affordability, support and relationships with partners are some of the reasons why we are winning over these customers. In the APAC region we had record revenues, Wi-Fi bookings were also very robust. We received a major enterprise order for over 7000 access points from Worldlink Nepal for outdoor Wi-Fi. We had our first win with a large telco managed service provider (NYSE:MSP) in Japan for our Wi-Fi business. The project involves connectivity for schools and hospitals and featured our Wi-Fi 6 product. This opens the door for future opportunities as the Japanese market is dominated by larger telecom MSPs, and we won this project over a larger competitor. And in Malaysia, one of the largest oil and gas companies in the region selected Cambium’s intelligent positioners with our PTP 450i for connectivity between oil rigs and oil tankers. In Caribbean and Latin America (NASDAQ:CALA) region, Cambium had a solid quarter with record bookings. We had a strong enterprise quarter with an education win in Brazil for 1600 schools in the State of Sao Paulo. Cambium's outdoor access points were selected versus several larger competitors due to our superior performance and total cost of ownership for the customer. Brazil represents a large opportunity to expand our enterprise business, and we are making tremendous progress in the country. We had a win with our 60 GHz and Wi-Fi combo for a major port in the CALA region to provide coverage across a facility in days. The maritime port authority found that mobile cellular service did not perform adequately in an environment where metal containers were moved and stacked on a continual basis. After deploying Cambium fixed wireless and Wi-Fi technology, the port experience consistent connectivity and higher data throughput. Our partners expanding their deployments to cover four additional force and equip two containerships. Turning to new product introductions since our previous quarterly update. We officially launched our first Wi-Fi 6E products, the XE-series, which triples the available spectrum for Wi-Fi usage including utilization up to 1.2 GHz of new clean spectrum in the 6 GHz band. The Wi-Fi 6E solution is a compatible solution with existing Wi-Fi 6 networks, and enables customers to upgrade to 6 GHz when they are ready without a price premium. We continue with extensive field trials and proof-of-concept deployments for our new 28 GHz cnWave 5G NR fixed wireless product with a formal launch during Q1 '22 and revenues beginning to ramp during calendar '22. Interest and demand from service providers is very high for this long sought after product, which uses millimeter wave for fixed wireless access in areas where it's not possible to use either fiber or traditional mobile technology like 4G or 5G. Our 28 gigahertz cnWave solution will include a mandatory software attach with cnMaestro X, our cloud based network management platform to support service delivery and Cambium Care for software maintenance and upgrades. One of our key goals for 2022 is to build a strong foundation for our software and subscription service business, which delivers customer stickiness, recurring revenue and accretive margin. We are building a sustainable subscription business through three principal initiatives. First, cnMaestro Essentials provides important core services valued by all of our enterprise and fixed wireless customers; and cnMaestro X provides enhanced services functionality and ecosystem integration for a fee basis. We continue to invest in cnMaestro X for enterprise and fixed wireless broadband network administration through organic development and ecosystem integration, including mandatory attach rates on certain products. Second, through the development and introduction of new products that are subscription first by design. During Q1 ‘22 we expect to launch our new quality of experience (QoE) service. QoE provides visibility and network traffic optimization and real time to mitigate congestion and control network traffic. This feature will be increasingly important to high bandwidth multi gigabit networks across wired and wireless platforms. Network operators subscribing to Cambium's QoE can optimize the average revenue per user ARPU and improve customer satisfaction. QoE allows network administrators to confidently offer higher service level agreements (SLAs) at targeted higher ARPU subscribers. Additional products are anticipated in the second half of 2022 to accelerate annual recurring revenue. Third, we are aligning, training and incentivizing our internal go-to-market teams, and more importantly our more than 10,000 global partners to effectively position and sell our subscription services. Having conducted business in approximately 170 countries in 2021, it is critical that we harness the knowledge, skill and presence of our channel partners to advance our subscription services business. 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 growth. The total devices under cloud management in Q4 '21 were over 744,300, an increase of 4% from Q3 '21 and up 42% year-over-year. The expansion and growth of our subscription services will be a multiyear journey for Cambium. In the coming quarters, we will provide investors metrics to measure our progress. Looking at the channel. In Q4 '21, we expanded our channel presence by adding over 530 net new channel partners sequentially and over 2,160 net new channel partners year-over-year, which represents an increase of approximately 5% sequentially and 24% year-over-year. I will now turn the call over to Stephen for a review of our Q4 '21 financial results and Q1 '22 and full year '22 outlook.

Thanks Atul. Cambium had revenues of $78.7 million for Q4 '21. Revenues increased by 4% quarter-over-quarter and decreased by 5% year-over-year. The global supply constraints continue to impact shipments of our Point-to-Multipoint and Point-to-Point products, while we had better than anticipated supply of Wi-Fi chips, enabling a record breaking quarter for our enterprise Wi-Fi business which had significant pent up demand and we opportunistically managed to obtain supply in the secondary market, increasing revenues by 140% sequentially and 136% year-over-year. Our backlog and end demand remains strong, with backlog increasing by 7% quarter-over-quarter and 16% year-over-year. On a sequential basis for Q4 '21, revenues were higher by $2.8 million. The higher revenues were primarily the result of record demand for enterprise Wi-Fi solutions and higher Point-to-Point revenues driven by our Federal business, an increased demand for backhaul products offset by lower Point-to-Multipoint revenues due to global supply constraints negatively impacting shipments of products. Moving to our gross margin, non-GAAP gross margin of 44.2% decreased by 700 basis points compared to Q4 '20. The year-over-year decrease on non-GAAP gross margin was a result of lower revenues and increased component costs as well as higher freight and distribution costs caused by expedited shipping. On a sequential basis non-GAAP gross margin was 360 basis points lower than Q3 '21. The lower quarter-over-quarter non-GAAP gross margin was also the result of high component costs and increased freight and distribution costs offset by a richer mix of Wi-Fi business. Our previously announced price increases began to help offset some of the gross margins degradation during the latter part of Q4 '21. We believe we will continue to see sequential improvements to gross margins during calendar 2022 from both the benefits of the actions we have already taken and increased scale in our business as we progress through the year. The full impact of both the price increases will be realized during the second half of 2022. In Q4 '21, our non-GAAP gross profit dollars of $34.8 million decreased by $7.6 million compared to the prior year due to lower volumes and were lower by $1.5 million sequentially. For the full year 2021, non-GAAP gross margin declined by 210 basis points to 48.2% compared to 50.3% for 2020 due to higher component costs and increased freight and distribution costs. Our longer term goal remains an annual non-GAAP gross margin target of 51% to 52%. Non-GAAP operating expenses, research and development, sales and marketing general administrative depreciation and amortization in Q4 '21 decreased by approximately $100,000 when compared to Q4 '20, and stood at $29.1 million or 36.9% of revenues. Year-over-year, we had increased sales and marketing expenses due to higher headcount and the returns to in-person tradeshows and customer meetings offset by lower R&D spending, while G&A remains flat. When compared to Q3 '21, non-GAAP operating expenses increased by $1.4 million during Q4 '21. Quarter-over-quarter sales and marketing increased as a result of higher headcount and return to in-person events, including WISPAPALOO

Cambium remains very well positioned for 2022 with multiple growth drivers, including our multi gigabit wireless products such as enterprise Wi-Fi 6 and 6E, Wireless semi switching products, 60 GHz cnWave and our 28 GHz millimeter wave solutions for fixed 5G. New 6 GHz fixed wireless solutions arriving later in 2022, a reinvigorated federal business as well as our software-as-a-service solutions. We expect increased scale should benefit our future operating results and we remain focused on judiciously managing our costs, while continuing to invest in innovative products to maintain our technology age. Finally, Cambium was named as one of the best places to work as a large company in Chicago area. The evaluation recognizes employers who have created a diverse, equitable and inclusive culture that support employees, no matter if they are in the office or at home. We also got named by Forbes as number 22 on their list of the best top 100 small cap companies for 2022. I would like to show my appreciation for our employees, partners and customers for their resolve during these unprecedented times. This concludes our prepared remarks. So with that, I would like to turn the call over to Carmen and begin the Q&A session.

Thank you. So first question comes from Scott Searle with ROTH Capital.

Steve, so I'm not sure, if I missed it. But did you provide a number in terms of what was left on the table due to supply constraints in the fourth quarter. And then looking to the first quarter guidance, I'm wondering if you could directionally give us an idea by product line, how that looks? Wi-Fi had an absolutely huge fourth quarter. Does that continue into the first quarter? How much recovery expecting are we on the MultiPoint front, given a lot of products, given the supply chain issues? I was wondering if you can talk about that? And then I have a follow-up.

Yes. I'll take. This is a Stephen and Atul can come in at the end if he has anything else to add. But it's tough to accurately quantify that in terms of what was left on the table. I think the best way to answer it is if you look at our peak revenues in 2021 prior to these major supply chain disruptions, they were approximately about $93 million. So I think it's fair to say given the increased backlog and momentum that we're seeing on our product lines at the moment, especially enterprises you commented on, you could expect that we would have been beyond that peak had we not been supply constrained. Certainly, our order book and the bookings activity and the backlog indicates that we can do much more than $93 million. You saw from those results, we benefited from some of the supply chain upsides in particular in enterprise in Q4. As you saw, we're hitting an annualized $100 million run rate for that business. So there's strong momentum in the business. Certainly, as I said, to sort of recap, higher than the what our previous peaks were was a fair way to assess it. With regards to growth rates by product line for Q1, again, we're living in a very dynamic environment with regards to the supply chain. But this is how we see it panning at the moment. So the PMP side of the business for Q1, we're seeing that in I would say, the upper 20s sequential growth rate. But PTP coming off a very strong Q4, I would say flattish, and Wi-Fi often exceptional record Q4, we're going to be down roughly about 40%. And then there's a little bit in other. But that should give you some flavor of the breakdown.

And lastly if I could, then looking to your guidance for fiscal '22 which is I think well above where the consensus is, it certainly implies an inflection as we get past the first quarter. So I'm wondering, in terms of your visibility, your comfort both on the supply and the demand side, does that start to happen in the second quarter or is that second half? And then as part of that, gross margin as well, right. Your targets being 51% plus, is it an exit rate in 2022? Is that possible? I know there's some price increases going through, but supply chain coming together? A lot of different elements there. To get to the numbers though, it certainly implies, right, that we start to see a pickup either in second quarter second half with improved gross margin Outlook. So I was wondering if you could provide some more color around that. Thanks.

Yeah, I mean, I think you're right, we still see -- and nobody's got a crystal ball at the moment, but we still see the first half of the year being more challenging from a supply chain perspective, and then that starts to ease in the second half. So you're going to start -- the two things is going to be happening in Q2 specifically. One is, hopefully we're going to see a slight easing of some of these supply constraints, obviously, it's not going to spring back to full supply, but we're going to start to see that ease. Coupled with again, you'll start to see layering in some of the price increases that will help revenue and gross margin. And then with regard to gross margin, I think we're going to see continual progression. You've already seen that in our guidance for Q1, were up almost 100 basis points in Q1 as some of these prices come in. And then you see a little bit more in Q2, and you'll see it improving in the second half of the year. It's hard for me to comment, whether we're going to get back into the 50s, because that's just too far out for us to predict at this point in time. But certainly, we've got a path to see continual progression and we're working towards that.

So I'll just add one comment. The new products we have introduced, very gratifying to see the adoption of 60 GHz worldwide and the 28 GHz funnel, very, very strong funnel, and the average deal size on 28 GHz 5G is much larger. We are seeing that dynamic. And the last point I' want to make is that, the government and defense will also accelerate I think in the second half. But overall from products point of view, we feel very good how we are positioned.

Next question comes from Samik Chatterjee with JPMorgan.

Hi, this is Joe Cardoso on for Samik. My first question is just on the revenue guide for 1Q, it sounds like this quarter you were up 4% quarter-over-quarter ahead of your guide. And I would assume that you'd see some sequential growth at that level or better heading into the first quarter, just given what you're talking about in terms of an improving or better demand backdrop. In terms of both our including seems robust backlog. And then on top of that, you're seeing improving supply from what seems to be your suppliers as well as some of the actions that you guys take -- took, but you only got in for kind of like a low-single-digit sequential improvement. I guess, what am I not understanding there, like, why aren't we seeing a stronger sequential increase going into the first quarter? It seems like all the -- you seems like you're benefiting from both the demand and supply easing already going into the first quarter of this year?

I'll take and then I’ll Atul comment at the end. But I think the bottom-line is, we're still in a very -- we and the rest of the industry are in a very challenging supply constrained environment. And so, every day provides a new set of challenges. And you're absolutely right, we've got ahead of this, we take some actions, we've moved on pricing, we've done some redesigns. And maybe you could say that our guide is a little bit conservative at this point in time. But I think we're seeing, modest progression where we're actually growing sequentially, and certainly hope we can beat that number. But I think that's sort of reflective of this environment that we see at this point in time. I think we think things have stabilized. We were particularly pleased on what happened in Q4 on some additional supply for enterprise. But likewise, we were curtailed in our PFP business on supply. So it's a bit of a moving target. So we've been a little bit conservative for our Q1 guide, and hopefully we can beat it.

I think Joe, just one point I want to add is. First half, you will see gradual improvements, that's why we're being conservative. I think the second half where we see accelerated improvements in supply chain. We work very closely with our partners, all the key chip features partners. So I think you're just seeing a level of conservatism, because I think we want to see couple of quarters of continued strong supply, which will then give us confidence and now it's on the accelerated path.

And then my follow-up questions a little bit much simpler. I know, apologies if I missed this in your prepared remarks, but it sounded like you gave us an update in terms of pricing. And when you're expecting to see the full benefits of that. Can I just get an update in terms of where you guys are at with the product redesigns that you talked about last quarter?

Let me take that one. We have done the first phase of our product redesign very well. And actually, that helped us with some of the acceleration in Q4. And yet, for in the first half, I think there will be some parts which will still be positive. So we keep looking at where we could readredesign. But I think the major redesign part is over, and pretty much built into our products.

Your next question comes from Rod Hall with Goldman Sachs.

I want to come back to the Wi-Fi. And obviously a huge number there, it feels like I think you've kind of commented on in the remarks that you had a lot of supply release there. But I'm just kind of curious, whether you might have changed your sourcing strategy a little bit here, I know that a tool, it's kind of a -- it's a footprint kind of model. So if you get that footprint over time that's worth something to you. So maybe it makes sense to overpay for chips, shorter term or pay more for them. So that you can supply it, I'm just curious kind of how you're thinking about that supply strategy now in the context of this market?

Sure. Let me take this. In terms of the particularly Wi-Fi chip supply, we have a very strategic partner, long range partner, we work very closely with them. And whatever price increases they announced publicly, that's all we are paying. But since we are driving a lot of innovation with their chips, we get good attention. And we do see improving situation in 2022, especially in second half. As I said, gradual improvements in first half, but I think pretty solid improvements -- that's the indication we get on the Wi-Fi that's fixed wireless broadband uses diverse set of chips. They are not just chipset, there we have to buy distinct chips from multiple vendors. So fixed wireless broadband is a little more sophisticated that way. That's why in general, fixed wireless broadband will kind of lag the Wi-Fi side because Wi-Fi side is a complete chipset to the partner we do. So hopefully that gives you a little more color.

Yeah, that's great, Atul. And just on the Wi-Fi again, could you just clarify the -- I mean, you're saying down 40% in Q1, and you know, this huge, almost doubling of revenues in Q4. Is that a -- was that a single deal or can you maybe dive into a little bit more about what drove that? It's such a gigantic fluctuation in numbers from one quarter to the next, so just like to make sure that I understand the detail on that?

Yeah, let me take this and if Stephen has any suggestion, he can add. I think some of the supplies for the chips came in late in Q3. So we could not turn that into Q3. Whereas we were able to use those chips which came very late in Q3 into Q4, and then the Q4 chip supplies are decent. So that's why use the pent up demand a little bit there. But this does tell you there is a strong demand, and as Wi-Fi situation keeps improving, you will see continuous improvement in our enterprise numbers, especially in the second half.

Yeah. And just to add to that, Rod, you know, I think that the guidance for Q1 on Wi-Fi, this is all supply related. We have a record -- not just a record number in Q4, but we got record bookings for enterprise. We enter the year with record backlog for enterprise. So this is us really navigating the supply constraints. And as Atul mentioned, we had a little bit pull in from Q3 and remember that, we had a disappointing Q3 on enterprise, again, all supply related. So that helped us out in Q4. And so we're navigating now Q1 with the continuous supply constraints.

And right to answer your specific question, no, there was no large deal, any such thing. We have lots of midsize, a large number of customers. But our average deal size is increasing in enterprise Wi-Fi. We are closing in more strategic accounts, but this doesn't include any large one time bluebird. It does not.

I got it. So it sounds like what we should do is just kind of smooth those numbers through Q3 and Q4, and we'd have a better picture of what the underlying kind of demand look like?

I think it’s the way of looking at it.

Your next question comes from George Notter with Jefferies.

I guess I also wanted to ask about the supply chain environment. You guys are talking about a substantial improvement in the second half of the year. And you're just going through earnings season, it certainly feels like that's a bit of a non-consensus view. I think many out there expecting to remain pretty tough through all of this year. But is there any more detail you can give us on exactly why you think the supply chain is going to ease for you in the second half? Is there -- is it specific conversations, specific fabs that are coming online, like what kind of detail can you give us there?

Let me take this. When you look at the Wi-Fi part, as I said, Wi-Fi part or chipsets, and they seems to be recovering faster, number 1. Number 2, in the Wi-Fi, about maybe nine months back or so we sensed that things are changing on Wi-Fi 4 and 5 versus Wi-Fi 6. So we shifted the design, we redesigned the product, we shifted the design to Wi-Fi 6. And we will benefit in 2022 and onwards with good strong leadership in Wi-Fi 6, because Wi-Fi 6 supply is I think improving faster because Wi-Fi 4 and 5 use older fabs. They are kind of lagging behind, there's definitely possibly a supply, so that's kind of Wi-Fi. The fixed wireless broadband, they use analog chips, they use variety of chips, DSPs, FPGAs. So I think what you will see, George, different dynamic for different companies. It depends upon what all chips you use, because not all chip vendors are improving at the same rate. They all use different fabs, some of 20, 28 nanometer or above some 20-nanometer or below. So in general, our read is for Cambium business, we will see a good improvement in Wi-Fi enterprise supply in second half. In the fixed wireless broadband, it might be a little behind compared to the enterprise, because of the reasons I mentioned complexity, different chips and all that. And we will keep you guys posted. We work very closely with our partners every week. We do meetings with them, all of them. And as a result, I think we believe we have a good handle on where things are.

Just to add to that, we mentioned on our last call about some of the redesigns that we were doing in fixed wireless to more widely available parts. So we do expect – and its all coming in the . We do expect some of those initiatives to work their way through the system, and help us out in the second half. I think from a sort of quantifying really what we're hearing from suppliers overall, certainly we're hearing from our vendors and our suppliers that things are improving. And they seem a little bit more committal to us for the second half of the year. But it's sort of wait and see mode at this point in time.

A few minutes ago, you kind of mentioned the bookings and backlog strength on the enterprise side of the business. Is that -- can you give us any comment on what you're seeing on fixed wireless access? Is that also strong in terms of bookings backlog and so on?

Bookings, backlogs, I would say strength is across pretty much all of our product lines. We entered the quarter with a higher backlog position. We are well over 100% of our guide for Q1. So I would say strength both for bookings and backlog goes across pretty much all of our front line.

And then the last one I was going to ask on was channel inventory levels. Any comments on where the channel stands right now in terms of inventory?

So as expected, we were more back end loaded with our shipments into the channel. And so there was a lot of product that was shipped towards right at the end of the year. So for the distributors to turn around and POS that was unlikely from a reporting perspective. So we did see a slightly higher level of channel inventory, which we expected, given as I say the linearity of shipments happening right at the end of the quarter. POS for the beginning of the year is strong, so we're expecting that to sell pretty nicely.

Our next question comes from Simon Leopold with Raymond James.

Hi guys, this is Victor Chiu for Simon. I just wanted to follow-up really quickly on the guidance. It seems like the 1Q adjusted EBITDA margin was for 6.7% to 8.8% 1Q, but for full year you’re guiding for 14% to 16%. So understanding that your expected improvement gradually throughout the year, but can you just help us bridge the gap a little on that trajectory that looks like there. Because that implies 3Q, 4Q EBITDA margins to kind of be well above the 16%, to kind of pin up to your guidance for the rest of the year? So can you just kind of help us flush that out a little bit first?

Yeah, I think Victor, the way you should be thinking about it, and we may have said it on previous calls, but 2022 is shaping out to be an inverse of 2021. And so if you think of '21, we had a phenomenal first half of the year, I think we peaked at EBITDA margins of almost 20%. So, our expectation is that supply chain constraints ease that will be a tremendous operating leverage in our model. So we'll see some nice leverage in the second half of the year because first half is going to be squeezed.

Okay. And I guess just could you speak some about the demand pipeline for the 28 GHz product by geographic region, I'm assuming most of demand for 20 GHz is driven primarily by international customers, mostly occupied by Tier 1 carriers in the U.S.?

Victor, let me take this one. So 20 GHz, as I said we are doing over eight POCs. And right now, I would say Cambium Networks has a clear line of sight to maybe over 50 service providers in our funnel. And what is very gratifying to see is so many countries are adopting 28 GHz 5G, number one. Number two, it gives the performance, as we are doing POC testing, it gives a performance of truly a gigabit type connectivity. So overall, very pleased to see. And one comment I made on my comments earlier, the average deal size on 28 GHz is much larger, because we are dealing with now larger tier 2s, and internationally some tier 1s as well, particularly in EMEA. So every quarter will give you a lot more flavor, but very excited about the 28 gigahertz 5G fixed. And Cambium product will be one of the leadership products in this segment.

Our next question comes from Tim Savageaux with Northland Capital.

You mentioned a couple of kind of, I guess government funding aided wins, I think more in the rip and replace category, which I think you're referring to a different kind of specific bucket of funds there relative to RDOF or anything else we see coming out us. And my question is to what extent was that a -- any type of that activity under whichever bucket you like, a contributor in '21? And as you look at your guidance and growth outlook for '22, what proportion of that growth would you say is accounted for by either the beginning ramps in RDOF or we're starting to hear about some acceleration here, or other government programs?

I'll take this one excellent question. I think there are multiple sources of government funding. There is definitely RDOF, which everyone has been tracking, which is focused on the rural side. Then there is infrastructure bill, which is focused on dissemination of that money through the local – through the states and local governments. But there's a third bucket, which is the CAF2. CAF2 is Connect America Fund 2, it was about $8 billion fund, I think 2 billion has been spent, but still has five years of life still before the funding has completely dissipated. So many of the projects which we participate are actually CAF2 and the CARES Act type of projects. When we look at the different domain funding, RDOF will probably start I would guess late this year, second half of this year, because we are into access. And there are still questions which need to be answered before the RDOF money really gets released completely. Some people have seen the benefit, but Cambium probably will see the benefit I would say maybe late this year. By an initiative we anticipate late this year or next year. So for us really at this point, some RDOF later this year, but really some of it is for us CAF2 and CARES Act funding, which we are participating right now.

So it sounds like not much?

No, I will say late this year maybe RDOF, but not much. CAF2 is the one where we are very active right now.

And this follow-up, again, focusing in on kind of the guidance for growth in '22. To what extent do you think price increases will contribute to that meaningfully? I know you talked about initiating one last quarter? Seems like you may have done that again in Q4, but -- and pretty significant in magnitude potentially. So this pricing play a significant role in which you're looking at for growth next year? Or sorry, this year?

I think you can assume the pricing is not terribly meaningful in the first half of the year. But once we work through the backlog, you're going to see the impact of that happen in the second half of the year. We've actually done two price increases one in Q3 and one in Q4, but obviously had a sizeable amount of backlog. So we're working through that. And once we do, you're going to start to see that more meaningfully materialize in the second half of the year.

And our last question comes from Chris Howe with Barrington Research.

Just asking a follow-up on some of these questions that you've already received here. First off with the cnMaestro product, you talked about the success that you're seeing there, still a several year timeline as we look at the maturation of software as a percent of overall business. Can you talk about the different puts and takes there as we navigate this timeline towards the positive, or perhaps getting beyond that initial double-digit percentage of revenue?

Let me take this. On cnMaestro, we have basically had two prong strategy. Strategy one, let you get adopted by the customers and now that we have hundreds of thousands of customers using cnMaestro we know it can scale it has a cloud architecture, it is reliable. Where we are going now with cnMaestro X is to offer enhanced services, which are highly differentiated. So let me give an example. So we offer for example, for MSPs, Managed Service Providers, very advanced dashboards. So they can manage hundreds of customers, and also brand properly for those customers. So that's a unique dashboard, we charge for that. Second, we're offering restful advanced API's. So some of these verticals, hospitality, education can integrate very specific applications, we charge for that. And then lastly, increase storage for not just a month, but maybe you want to see analytics over one year period, we charge for that. So very specifically, we are offering differentiated services and we charge for that. The basic management which is very necessary for the radios, that's part of the base product. Hopefully, that gives you a flavor, how we are layering the monetization.

And just following up on the question about government programs, you still have many that are in the pipeline, like RDOF and the Infrastructure Bill that will happen later this year and into next year. As we take next year -- and kind of from an overall perspective obviously, and look at the thematics compared to this calendar year, how should we think about that in terms of the sustainability of demand, especially when you consider some of these newer products, 28 and 60, will be much further down the line?

Right, I think – lets go one by one. RDOF, as I said for us, by the time we start to see money flowing for our solutions will be probably late this year, early next year is my sense. And RDOF is going to be going for more in a gigabit access, things like that. So the products we are coming out with especially in 6 GHz band that will be very well suited for that market. Biden Initiative is about a year away for us. So I think ‘23 onwards -- and I think one thing to keep in mind is all of these things are multiyear plans, they won't just get disseminated in one year, it'll take probably 3, 4, 5 years to keep building the infrastructure, to keep providing connectivity to unconnected. So overall, my sense is ‘23 is probably when we start to see meaningful acceleration for Cambium and then it’s a multiyear prong from that point onwards. And the new products we are doing, many of them are providing the foundation, which will give us not just a gigabit connectivity but also 500 megabit connectivity, 200 megabit connectivity for scalable networks at very different price points. So that's one thing Cambium will offer. Different price points, different scalability and a very good economic equation.

And now I would like to turn the call back to our Senior Director of Inventor and Industry Analyst Relations, Peter Schuman, for his closing statement.
