With fiber deployments accelerating around the world and with operators seemingly on a daily basis announcing additional fiber expansion projects, there is no question that the competition for broadband subscribers and revenue is intensifying faster than some operators would prefer. Because of that intensification and because of the time and cost required for fiber network deployments, operators are increasingly using a range of technologies for their fiber networks. System vendors have made this easier by adopting combo optics and combo cards that can support a range of technologies, from 2.5G GPON to 25G PON, and potentially beyond. Equipment vendors have heard the call from their operator customers that they need to have every tool available to them to succeed in a highly-competitive environment.

Although operators are, for the most part, still in the early stages of deploying gigabit and multi-gigabit services using XGS-PON, their fiber expansions are opening up additional opportunities for applications and new addressable customers that already require speeds beyond what XGS-PON can provide. For example, large enterprises and campus environments, which have typically been served by point-to-point Ethernet connections, are increasingly being passed by PON ODNs, especially those enterprises that are adjacent to residential neighborhoods.

Though the ITU (International Telecommunication Union) has determined that single channel 50G PON as defined in its G.hsp.50pmd specification is the next generation technology it will move forward with, the increasing use cases for PON combined with those use cases requirements for additional speeds beyond what XGS-PON can provide have opened the door for 25G PON as an important tool in operators’ toolboxes. The current strength in fiber buildouts and the need to address new use cases today has resulted in a list of operators who simply can’t wait for 50G PON to be fully standardized, tested, and productized.

In today’s hypercompetitive broadband market, timing and the availability of the right technology tools are everything. Although 50G PON provides a tremendous theoretical boost in speeds, the timeline for its availability is still an open question. China Mobile is on the record saying that it will begin limited deployments of 50G PON beginning in 2023. However, the CAICT (China Academy of Information and Communications Technology) has stated that it believes mass-market deployments of 50G PON won’t occur until the second half of this decade. With XG-PON deployments just hitting their stride as of last year and a typical deployment cycle of around 5-7 years for each new technology, the CAICT’s estimate seems to be more realistic. Even if we split the difference, the market is still looking at 2025 as the earliest point at which 50G PON sees meaningful deployments for residential applications.

One of the biggest challenges to overcome for all 50G PON component suppliers and equipment vendors is the increased optical power budget required. Additionally, the proposed integration of DSPs (Digital Signal Processors) is a significant change, as they have not been required in PON technologies before. Incorporating DSPs theoretically allows for the use of lower-cost 25G optics, which are widely available and mature. DSPs allow for the support of both OOK (On-Off keying) and OFDMA (Orthogonal Frequency Division Multiple Access). This support is critical for operators as it allows them to re-use their existing ODN (Optical Distribution Network) and not have to make significant and costly changes that could impact thousands of subscribers.

DSP-enhanced PON technologies are already being put through their paces, with China Mobile having demonstrated transmission rates of 41G downstream and 16G upstream in a hybrid environment using a 50G PON ONT as well as a 10G PON ONT. Meanwhile, Nokia has demonstrated 100G PON in conjunction with Vodafone at a lab in Germany. Both trials occurred in 2021 and more proof-of-concept work is expected throughout this year.

This brings us back to 25G PON. Although the traditional method of developing a technology for wide-scale deployment is to work through one of the primary standards bodies (ITU and IEEE), that avenue was closed to Nokia and other component suppliers and service providers who were interested in seeing both 25G PON and 50G PON standardized through the ITU, as well as accelerating the availability of 25G PON technologies to bridge the gap between today’s 10G technologies and tomorrow’s 50G and 100G options. So, the collection of vendors and operators organized the 25GS-PON MSA (Multi-Source Agreement) to develop standards, define interoperability, and generally help to evolve the technology outside the traditional standards organizations. The group’s members include AT&T, Chorus, Chunghwa Telecom, Cox Communications, NBN, Opticomm, and Proximus—service providers with the collective buying power to make the R&D effort worthwhile for the growing list of component and equipment vendors who are also members.

CableLabs, which focuses on developing standards and technologies on behalf of its cable operator members, is also a member of the MSA. Just like their telco counterparts, cable operators are trying to determine their bandwidth requirements in residential networks over the next few years, so having a choice among technology options is important. But unlike telcos, cable operators also have to determine whether they will satisfy these future bandwidth requirements with DOCSIS 4.0 and their existing coax plant or whether they will do so with fiber. In both cases, 25G PON is being examined as both a residential technology beyond current 10G DPoE (DOCSIS Provisioning over EPON) options and also as a potential aggregation technology for both remote PHY and remote MACPHY nodes.

CableLabs is also working on its own initiatives, including single wavelength 100G Coherent PON, which is seen as an ideal long-term option for cable operators who have wide ranges of fiber span lengths (up to 80km) and need spit ratio sizes that are more akin to today’s service group sizes of 200-500 homes passed per node. Nevertheless, the timeline for 100G Coherent PON, like 50G PON, is still being determined.

Expanding use cases for PON driving the need for 25G

Beyond the uncertain timing of 50G PON, as well as the desire for technology choice, one of the primary reasons for the short-term demand for 25G PON is simply the desire to use PON in applications that go well beyond traditional residential broadband access. It is actually in these applications where 25G PON will see the most deployments, particularly within the next 2-3 years.

Enterprise services have typically been point-to-point Ethernet connections. But as operators expand their PON ODNs to support residential and small-medium business applications, 25G PON can be implemented to deliver symmetric 10G connections, comparable or better than what enterprises are accustomed to. Because 25G PON has been designed to co-exist with both GPON and XGS-PON, service providers can have the flexibility of using the same OLT to deliver both high- and low-SLA traffic or they can split that traffic and customer base across multiple OLTs. Either way, the existing ODN remains intact.

Additionally, service providers are also interested in 25G PON their 5G transport networks, particularly in the case of small cell transport. Though LTE networks never resulted in the type of volume deployments of PON equipment to support backhaul, there is more consensus that the PON technology options available now provide the bandwidth (symmetric 10G) along with the latency requirements necessary to support 5G services and corresponding SLAs.

Clear Upgrade Path

Though standards bodies have traditionally defined which technologies get adopted and when there are certainly cases where operators have placed their thumbs on the scales in favor of a preferred option. These choices don’t generally go against what the standards bodies recommend or are working towards. Instead, they satisfy a more immediate internal requirement that doesn’t mesh with the proposed standardization, certification, and product availability timeline defined by the standards bodies and participating equipment suppliers.

Larger operators, including AT&T, BT Openreach, Comcast, and Deutsche Telekom, have also become far more comfortable over the last few years defining standards and pushing them through other industry organizations, such as ONF and the Broadband Forum. These operators know they have the scale and market potential to drive standards and thereby influence the product roadmaps of their incumbent equipment suppliers. There are always others waiting in the wings or the threat of moving to completely virtualized, white box solutions that would reduce the revenue opportunity for said vendors.

And that’s what appears to be happening with 25G PON. Service providers that are part of the MSA are certainly voting with their pocketbooks. Nokia, for its part, has made things quite simple for these operators: Use GPON and XGS-PON today for the bulk of your residential FTTH deployments, and then add in 25G PON using the same equipment and ODN where it makes strategic sense. Nokia does indeed seem to be seeding the market, has reported a cumulative total of 200k 25G-Ready PON OLT ports through 3Q21, with a bigger jump expected in the fourth quarter.

Nokia realizes it must make hay now while the timeline around 50G PON remains in flux and demonstrations of its performance in labs remain limited.

But the PON market has always been one offering different technology options to suit each operator’s unique use case requirements and competitive dynamics. That flexibility is proving to be particularly beneficial in today’s hypercompetitive broadband environment, in which each operator might have a different starting point when it comes to fiber deployments, but likely has similar goals when it comes to subscriber acquisition and revenue generation. In this environment, many operators have clearly said that they simply can’t wait on a promising technology when they need to establish their market presence today. And so, the vendor ecosystem has responded again with options that can steer them down a path to success.

Data centers are the backbone of our digital lives, enabling the real-time processing of and aggregation of data and transactions, as well as the seamless delivery of applications to both enterprises and their end customers. Data centers have been able to grow to support ever-increasing volumes of data and transaction processing thanks in large part to software-based automation and virtualization, allowing enterprises and hyperscalers alike to adapt quickly to changing workload volumes as well as physical infrastructure limitations.

Despite their phenomenal growth and innovation, the principles of which are being integrated into service provider networks, data centers of all sizes are about to undergo a significant expansion as they are tasked with processing blockchain, bitcoin, IoT, gigabit broadband, and 5G workloads. In our latest forecast, published earlier this month, we expect worldwide data center capex to reach $350 B by 2026, representing a five-year projected growth rate of 10%. We also forecast hyperscale cloud providers to double their data center spending over the next five years.

Additionally, enterprises are all becoming smarter about how to balance and incorporate their private clouds, public clouds, and on-premises clouds for the most optimal and efficient processing of workloads and application requests. Similar to highly-resilient service provider networks, enterprises are realizing that the distribution of workload processing allows them to scale faster with more redundancy. Despite the general trend towards migrating to the cloud, enterprises will continue to invest in on-premises infrastructure to handle workloads that involve sensitive data, as well as those applications that are very latency-sensitive.

As application requests, change orders, equipment configuration changes, and other general troubleshooting and maintenance requests continue to increase, anticipating and managing the necessary changes in multi-cloud environments becomes exceedingly difficult. Throw in the need to quickly identify and troubleshoot network faults at the physical layer and you have a recipe for a maintenance nightmare and, more importantly, substantial revenue loss due to the cascading impact of fragmented networks that are only peripherally integrated.

Although automation and machine learning tools have been available for some time, they are often designed to automate application delivery within one of the multiple cloud environments, not across multiple clouds and multiple network layers. Automating IT processes across both physical and virtual environments and across the underlying network infrastructure, compute and storage resources have been a challenge for some time. Each layer has its own distinct set of issues and requirements.

New network rollouts or service changes resulting in network configuration changes are typically very labor-intensive and frequently yield faults in the early stages of deployment that require significant man-hours of labor.

Similarly, configuration changes sometimes result in redundant or mismatched operations due to the manual entry of these changes. Without a holistic approach to automation, there is no way to verify or prevent the introduction of conflicting network configurations.

Finally—and this is just as true of service provider networks as it is of large enterprises and hyperscale cloud providers—detecting network faults is often a time-consuming process, principally because network faults are often handled passively until they are located and resolved manually. Traditional alarm reporting followed by manual troubleshooting must give way to proactive and automatic network monitoring that quickly detects network faults and uses machine learning to rectify them without any manual intervention whatsoever.

Automating a Data Center’s Full Life Cycle

As the size and complexity of data centers continue to increase and as workload and application changes increase, the impact on the underlying network infrastructure can be difficult to predict. Various organizations both within and outside the enterprise have different requirements that all must somehow be funneled into a common platform to prevent conflicting changes to the application delivery layer all the way to the network infrastructure. These organizations can also have drastically different timeframes for the expected completion of changes largely due to siloed management of different portions of the data center, as well as different diagnostic and troubleshooting tools in use by the network operations team and the IT infrastructure teams.

In addition to pushing on their equipment vendor and systems integrator partners to deliver platforms that solve these challenges, large enterprises also want platforms that give them the ability to automate the entire lifecycle of their networks. These platforms use AI and machine learning to build a thorough and evolving view of underlying network infrastructure to allow enterprises to:

- Support automatic network planning and capacity upgrades by modeling how the addition of workloads will impact current and future server requirements as well as the need to add switching and routing capacity to support application delivery.
- Implement network changes automatically, reducing the need for manual intervention and thereby reducing the possibility of errors.
- Constantly provide detailed network monitoring at all layers and provide proactive fault location, detection, and resolution while limiting manual intervention.
- Simplify the service and application provisioning process by providing a common interface that then translates requests into desired network changes.

Ultimately, one of the key goals of these platforms is to create a closed-loop between network management, control, and analysis capabilities so that changes in the upper-layer services and applications can drive defined changes in the underlying network infrastructure automatically. In order for this to become a reality in increasingly complex data center network environments, these platforms must provide some critical functions, including:

- Providing a unified data model and data lakes across multiple cloud environments and multi-vendor ecosystems
  - This function has been a long-standing goal of large enterprises and telecommunications service providers for years. Ending the swivel-chair approach to network management and delivering error-free network changes with minimal manual intervention are key functions of any data center automation platform.
- Service orchestration across multiple, complex service flows
  - This function has also been highly sought-after by large enterprises and service providers alike. For service providers, SDN overlays were intended to add in these functions and capabilities into their networks. Deployments have yielded mixed, but generally favorable results. Nevertheless, the principles of SDN continue to proliferate into other areas of the network, largely due to the desire to streamline and automate the service provisioning process. The same can be said for large enterprises and data center providers.

Although these platforms are intended to serve as a common interface across multiple business units and network layers, their design, and deployment can be modular and gradual. If a large enterprise wants to migrate to a more automated model, it can do so at a pace that is suited to the organization’s needs. The introduction of automation can be done first at the network infrastructure layer and then introduced to the application layer. Over time, with AI and machine learning tools aggregating performance data across both network layers, correlations between application delivery changes and their impact on network infrastructure can be determined more quickly. Ultimately, service and network lifecycle management can be simplified and expanded to cover hybrid cloud or multi-vendor environments.

We believe that these holistic platforms that bridge the worlds of telecommunications service providers and large enterprise data centers will play a key role in helping automate data center application delivery by providing a common window into the application delivery network as well as the underlying network infrastructure. The result will be the more efficient use of network resources, a reduction in the time required to make manual configuration changes to the network, a reduction in the programming load for IT departments, and strict compliance with SLA guarantee to key end customers and application provider partners.

Broadband Focus Will be Squarely on Fiber and Increased Competition in 2022

The emphasis on and investments in advanced broadband access networks around the world over the last two years shows no signs of abating in 2022. Despite the headwinds of component and labor shortages, inflation, and logistics snafus, broadband network buildouts and upgrades, coupled with net subscriber additions are projected to result in over $15.5 B in equipment spending in 2021. With the sustained influx of new capital from both governments and private equity, 2022 spending should be equally strong.

The 2021 results were somewhat of a surprise to some, as there were expectations that students returning to in-person instruction and workers partially or fully returning to their offices would result in a reduction in home broadband subscriptions that had been added in 2020 at the height of the pandemic. But, net subscriber additions didn’t decline and in fact accelerated throughout 2021. For those of us who have monitored the broadband market for some time, this wasn’t a surprise, as broadband remains one of the stickiest services a provider can offer. Though there is churn, as there is with many services, once broadband is in the home, it more than likely will remain and be integrated into the household budget.

As a result, investments in broadband infrastructure—specifically fiber networks—have skyrocketed, with private equity fueling a growing number of buildouts in North America and Europe. Investing in network infrastructure—which hasn’t been cool since the late 90’s—is suddenly all the rage. As such, the valuations of fiber networks have increased significantly, driven by increased demand for residential broadband, ongoing 5G network buildouts, and an expectation that fiber networks still need hundreds of billions in new investments to keep pace with expected bandwidth demand.

Of course, national Government plans including the RDOF (Rural Digital Opportunity Fund) and Build Back Better programs, as well as tax incentives in the UK and other European countries, intend to cover some of that necessary investment. But that hasn’t pushed private investment to the sidelines. All of this means that 2022—even 2023—should be very strong years for broadband equipment manufacturers.

Changes in the Competitive Landscape Will Force Cable Operators to Move Faster

Before discussing the expected impacts on specific broadband technologies and products, it’s critical to look at how sustained investments in fiber and even fixed wireless networks will dramatically alter the competitive landscape in broadband. The biggest change to the overall market that these investments provide is not only availability where it didn’t exist before, especially in the case of rural and underserved markets, but also the introduction of choice where that didn’t really exist before. In North America and a number of Western European countries, realistic consumer choice among multiple broadband service providers has only recently begun to increase. In most areas, the choice has been between cable and DSL, with cable operators able to offer speeds that satisfy increased subscriber requirements, while DSL languishes at sub-50 Mbps speeds. The net result—especially in the US market—was broadband market dominance to the tune of over 65%.

That dominance has certainly benefited cable operators and kept their subscriber base and margins growing in the face of sustained pay-TV service cancellations. But in some cases, it has also not prepared them adequately for the significant changes that are headed their way in the form of new fiber-based competitors. Some cable operator executives have been downright dismissive of the looming threats—especially those coming from fixed wireless.

Tom Rutledge, CEO of Charter Communications, said back in September 2021 that, “We actually look forward to a higher churn environment…We do well with prospects looking to change their services.” In a world where Charter was competing only with DSL providers, the company clearly did well and has continued to excel in pulling away dissatisfied DSL subscribers who required more speed but couldn’t get it, especially during the pandemic.

But going up against fiber providers with consistent gigabit (and even multi-gigabit speeds) is an entirely different story altogether, one in which the MSOs could find themselves in a similar position to previous DSL providers. We have already seen a slowdown in net new broadband subscribers among some of the largest US cable operators. That slowdown has been attributed to (among other things) an expected decline in subscriber churn from DSL providers largely because there are so few left to poach.

But with AT&T, Verizon, Frontier, Ting, Sonic, and other providers posting increasing fiber subscriber additions, at least some of the subscriber slowdown at Charter and others has to be attributed to these subscriber gains being made at the cable operators’ expense. So much for being successful in high-churn environments.

In this new battle, cable operators are also saddled with the consumer perception that they are not providing value even if they are providing the fastest speeds available in a particular area. Part of this perception is due to the longstanding residue of consumers consistently ranking their cable providers at the bottom of the list for value and customer service. It’s one reason why people have dropped (and continue to drop) their pay-TV subscriptions so quickly. Again, so much for being successful in high-churn environments.

So, what does this mean for cable operators, from the perspective of infrastructure investments and technology rollouts? There are a couple of implications:

There will be a growing percentage of tier 1 cable operators who increase their investments in fiber infrastructure. We have already seen a decent number of tier 2 and tier 3 operators in North America opt for the complete replacement of their HFC networks with full fiber. While we certainly don’t expect to see a wholesale cutover among any tier 1 cable operators, we believe this year will see an increase in fiber overbuilding in some of the more competitive markets in order to maintain the perception of parity with fiber competitors.
Tier 1 operators will push very hard to accelerate the DOCSIS 4.0 product availability timeline. We are already seeing hints of this with system vendors pursuing silicon partnerships outside of Broadcom in order to expedite the availability of products, particularly remote-MACPHY devices. We are also already seeing announcements of successful lab trials using both full-duplex DOCSIS and extended-spectrum DOCSIS to deliver multi-gigabit speeds.

In the short term, we fully expect cable operators to continue their current mid- and high-split upgrade projects to increase upstream bandwidth for their DOCSIS 3.1 networks. This will result in sustained DOCSIS channel license purchases through at least the first half of the year and perhaps throughout the year, with a growing percentage of those licenses being supported on vCCAP platforms in support of R-PHY deployments, as well as on R-MACPHY devices.

Speaking of R-MACPHY, the availability of products that adhere to the Flexible MAC Architecture (FMA) specification will accelerate this year, with MAC Manager products moving from the lab to field trials later this year. The availability of these products, while not an absolute requirement for DOCSIS 4.0, are important stepping stones in continuing the further disaggregation of the I-CCAP and vCCAP platforms, which is viewed as an important precursor for many cable operators as they begin their journey to DOCSIS 4.0, either in the form of Extended Spectrum DOCSIS or Full-Duplex DOCSIS. Additionally, some MSOs view FMA as a way to open the door to more fiber deployments, as remote OLTs and ONTs can be managed similarly to cable modems.

Within the home, cable operators are going to move quickly to expand the availability of high-end residential gateways that include both Wi-Fi 6 and, in the US Wi-Fi 6e. Comcast recently announced a new Wi-Fi 6e gateway manufactured by Technicolor that will be reserved initially for those customers taking its gigabit service offering. Comcast’s positioning with the gateway is that it offers the fastest speeds to and within the home. Fiber doesn’t make any difference if the W-iFi gateway in the home is anything less than Wi-Fi 6 or Wi-Fi 6e.

Fiber Expansion Will Accelerate

The switch from copper to fiber among the world’s largest telcos really became clear in 2020 and 2021. That trend will accelerate in 2022, in particular, because of the investments made this year in new optical line terminal (OLT) ports. Operators throughout North America, EMEA, and CALA switched more of their capex towards expanding their fiber networks than sustaining their DSL networks. This was clear at Telmex, BT OpenReach, and others. Major projects at Deutsche Telekom, Orange, Proximus, and elsewhere will drive not only more fiber expansion but 10 Gbps deployments using XGS-PON.

Fiber access networks have reached a major tipping point, driven by the simultaneous catalysts of the shift to next-generation fiber technology and the shift to openness, disaggregation, and automation. The world’s largest broadband providers are quickly realizing that the need for increased throughput is matched by the need for a highly-scalable network that can respond quickly to the changing requirements of the service provider, their subscribers, and their vendor and application partners. The need to provision and deliver new services in a matter of hours, as opposed to weeks or months, holds just as much priority as the ability to deliver up to 10 Gbps of PON capacity. Although service providers might have completely different business drivers for the move to open, programmable networks, there is no question that the combination of data center architectural principles and 10G PON technology is fueling a forthcoming wave of next-generation fiber networks upgrades.

The service providers that adopt the combination of 10 Gbps PON and openness will be best prepared to accomplish three major goals:

Deliver the advanced, 10 Gbps capacity, and multi-gigabit services subscribers will expect and require using a cloud-native infrastructure that treats bandwidth and the delivered applications as workflows.
Anticipate and whether rapid increases in traffic demand with a highly-targeted and elastic infrastructure that can be activated without a forklift upgrade.
Develop an access network infrastructure that can process multiple workloads beyond broadband access, including hosted services that can be offered on a wholesale basis, as well as fixed-mobile convergence applications.

According to many operators around the world with cable, DSL, and fibre broadband networks, upstream peak traffic growth throughout 2020 increased more than 50 percent, while downstream peak traffic growth increased 30 percent… Although the world is gradually returning to normal, with teleworkers moving slowly back into their offices, there is simply no turning back now for broadband subscribers who either upgraded or switched to an FTTH service.

The global demand for broadband service has resulted in an acceleration of interest among fixed and mobile operators alike to either expand their existing LTE or point-to-multipoint fixed wireless offerings or roll out early 5G services to a growing base of current and potential subscribers. In both mature and emerging markets, there has been a tremendous increase in the number of RFPs for equipment and software to support large-scale 5G fixed wireless service deployments. Clearly, service providers are looking to strike while the iron is hot, securing subscribers who need broadband now, while also taking advantage of growing government subsidization of broadband service rollouts.

The vendor ecosystem supporting 5G fixed wireless has naturally increased, particularly in the area of dedicated CPE. According to the GSA (Global mobile Suppliers Association), there are currently over 130 FWA CPE devices (both indoor and outdoor) that have been announced by a growing list of vendors, which now numbers above 50. Over 50 of these dedicated CPE are now commercially available, which is up from 15 commercially-available units just one year ago. By the end of 2021, we expect that the number of commercially-available devices will exceed 100 and will double in 2022. The number of vendors producing or planning to produce 5G FWA CPE already exceeds the number of suppliers of 4G FWA CPE.

The increase in available units, which corresponds with the perceived addressable market of 5G network deployments and subscriber uptake, combined with the rapid uptake of 5G-capable smartphones will help to push the cost of both indoor and outdoor 5G FWA units down to levels that satisfy the business case requirements of operators globally. In particular, operators in emerging markets where ARPU levels are typically low, cost-reduced CPE are an absolutely critical requirement to ensuring a faster ROI.

The larger the addressable market, the more willing component suppliers will be to forward-price to capture a larger share of that growing market. The resulting price reductions in components begets wider availability of finished CPE. It becomes an iterative cycle that benefits the entire supply chain and the network operators as end purchasers.

Quick Ramp of 5G FWA Devices Expected

At the end of 2020, we estimate that there are nearly 60M fixed wireless subscribers globally. A large percentage of these subscribers use 4G LTE networks, though there are also subscribers using 3G networks, proprietary point-to-multipoint services, as well as some using early 5G technologies, including sub-6Ghz and millimeter wave. We estimate that the 5G subscribers are around 1 million currently. However, we expect that those subscriber numbers are set to double in 2021, as operators such as T-Mobile (USA), AT&T, Verizon, Bell Canada, Saudi Telecom, Rain (South Africa), Swisscom, Deutsche Telekom, Optus, and others introduce or expand 5G FWA services this year.

With those operator commitments already in place, we estimate that the total number of 5G FWA devices shipping to operators this year will easily exceed 3 million units and could push 4 million units. The vast majority of these units will be to support sub-6Ghz service offerings, though we also expect to see millimeter wave units, as some operators use a combination of those technologies to provide both extensive coverage and fiber-like speeds in areas where the competition from fixed broadband providers is more intense. Overall, however, we expect volumes first from sub-6GHz units this year and into next year, followed by increasing volumes of millimeter wave units beginning in the latter part of 2022 and into 2023.

We also anticipate that the vast majority of 5G FWA deployments will rely on indoor gateways that combine a 5G modem with a WiFi 6 access point for signal distribution within the home. Many of these gateways will also be mesh-capable and will be paired with satellite units to blanket homes with WiFi coverage and to eliminate dead spots within the home.

There will be situations where outdoor units will be required, particularly in the case of millimeter wave deployments which require line of sight because of the high-frequency ranges being used. But even in the case of sub-6Ghz 5G FWA deployments, outdoor units will be required when homes or apartments have very thick-paned windows or are located in LEED (Leadership in Energy and Environmental Design) buildings.

With this growing clarity around deployment models and device types, we expect that the costs of 5G FWA CPE will decline throughout this year and next, providing a catalyst for much larger, global deployments of the service through 2022 and beyond. We believe that the average cost for an indoor 5G FWA CPE supporting sub-6GHz frequency bands will decline from around $350 in 2020 to around $100 by the end of 2023 (Figure 2).

5G chipsets will see the biggest price declines, helped in large part by increasing volumes of 5G smartphones, but also by a growing ecosystem of 5G modems, gateways, tablets, cars, and other products reliant on 5G networks for WAN connectivity. Currently, 5G SoCs are roughly 4x the cost of 4G SoCs. But we have seen this played out before in the early stages of 4G network and device rollouts when the cost of chips dropped quickly as device volumes increased.

Similarly, the cost of WiFi 6 chips remains about 15-20% higher than WiFi 5 units. While WiFi 6 will be the primary technology for mature, highly competitive markets, WiFi 5 will remain an important option for very price-sensitive markets, particularly those in developing countries and in rural markets where competition comes from lower-cost services. But as enterprise and higher-end residential gateways are built with WiFi 6 technology, the cost of those chips will decline significantly over the next couple of years.

Beyond these two major components, manufacturing costs will also decline as equipment and contract manufacturers increase volumes based on initial board and hardware designs. FWA gateway designs, like higher-end residential WiFi access point designs, are well-understood at this point. However, with any new product spin, there is a learning curve for the manufacturers. Though the cost of producing the first few thousand units is high, the costs quickly decrease as the manufacturing process becomes clearly defined and as new iterations of the devices incorporate lower-cost components.

There are two critical components for the steady reduction in cost for 5G FWA CPE: Increased orders and volumes from service providers, along with the cooperation among providers of 4G CPE devices and 5G units to understand how to bring down the costs as quickly as possible. This cooperation will be necessary to stimulate interest among service providers, who can then drive the volumes necessary to improve the overall economics of delivering 5G fixed wireless services.

5G FWA Will Build on 4G Deployments

Though the deployment of FWA services using 4G LTE networks has been moderately successful around the world, 5G will dramatically boost the addressable market of subscribers, as well as the service’s ability to reasonably compete with most fixed broadband technologies. 5G can comfortably deliver downstream speeds that compare favorably with VDSL and DOCSIS 3.0 services while easily beating previous generations of both fixed technologies. More importantly, C-band and millimeter wave technologies promise to be comparable with DOCSIS 3.1 and fiber services, thereby expanding the addressable market of subscribers even further.

Mobile operators around the world who have previously been unable to compete with fixed broadband providers, as well as fixed broadband providers looking to expand the reach of their services more quickly, are all enthusiastic about the opportunity in front of them with FWA. Their growing commitment to the service, as well as a rapidly expanding vendor ecosystem for customer devices, will help to quickly reduce the cost of those devices, thereby ensuring a faster ROI for service providers and a willingness to expand their reach even further.
