Federated Wireless announced that it will offer a managed service that will be offered to enterprises that plan to operate private cellular networks (both 4G and 5G). For companies to use Citizens Broadband Radio Service (CBRS) spectrum (3.5 GHz) in the US market, a service provider called a SAS is required; Federated is a pioneer in this SAS market. What the company announced today, though, is that not only is it going to offer SAS services to customers, but it will now offer discovery, planning, design, building, operations and support services that will allow enterprise to get the benefit of cellular coverage in their facilities.
Another very interesting facet to the Federated Wireless entry to managed services is that it has also announced selling partnerships with Amazon Web Services and Microsoft Azure. In summary, customers can visit each AWS or Azure sites, click some buttons and then Federated will show up and build and operate the cellular network to allow services such as critical communications (like employee-to-employee communications), mobility services (such as trucks moving onsite), Wi-Fi backhaul (without the need for installing new conduit and wires), IoT sensor deployment, and many other uses.
Federated will be an enabler to companies who don't want to work with traditional mobile network operators in order to expand cellular coverage to their corporate locations. What this means is in the US market, companies may contact AT&T, Verizon or T-Mobile to get licensed cellular, but now they can contact Federated Wireless to get their own shared-spectrum, in this case CBRS, network that carries only their traffic.
We expect that Wi-Fi 6E products to hit the market as soon as 3Q20 in the US and by 4Q20 in Europe. The appeal of these new 802.11ax products is that they operate not just in 2.4 GHz and 5 GHz, as 802.11ac products have, but now add 6 GHz spectrum support. The US products will likely support 1.2 GHz of spectrum, while European products may support about 0.5 GHz of spectrum.
We expect that throughput of higher-end Wi-Fi 6E access points may exceed 5 Gbps under some operating conditions, which may drive the discussion towards 10 Gbps switching. The higher throughput "backhaul" may mean that MultiGig Ethernet (that operates at 2.5 Gbps and/or 5 Gbps and takes advantage of older copper cabling installed primarily for 1 Gbps switches) could get another use-case compared to a scenario where 6 Ghz support never came to market. There is also another potential that the market moves faster to 10 Gbps and/or fiber.
We will be publishing our forecasts for Wi-Fi 6 (802.11ax), MultiGig Ethernet and 10 Gbps Ethernet in a few weeks. These forecasts will incorporate final 2019 numbers from vendors, as well as our updated views on 2020 macroeconomic scenarios, and the potential coronavirus impact (corvid-19).
Today, Amazon kicked off AWS Re:Invent with the Andy Jassy keynote. We were impressed to see David M. Solomon, CEO of Goldman Sachs, on stage, talking about how the Apple credit card was built on top of AWS. The claim that it could not launch a card like that without the Cloud was interested.
On to chips…
Graviton 2 was announced today. 64 cores, 7nm with 25 Gbps networking is impressive for a 2nd generation CPU. Graviton 2 being on 7nm already is also very impressive, showing how far and fast Anapurna has gone since being acquired by Amazon. Amazon claimed a 40% better price-performance than x86.
New Inf1 instances for AI. Built on Anapurna chip development. Again, quoting a 40% lower cost than the lasts NVIDIA chips for inference.
Some other highlights of today included:
40% of new AWS customers start with Fargate for containers
SSD speed is outpacing the CPU and networking, potentially causing a bottle neck
The largest amount of PoPs, backbone, and direct connect of any IaaS provider
Last week, at Nokia's analyst meeting in Helsinki, it discussed its achievements and its challenges. The company’s successes include its traction and product introductions on the enterprise market, its market traction in selling Nokia’s end-to-end portfolio, and its 5G market momentum. Management reiterated that Nokia has signed 50 5G deals and its products are involved in 16 live 5G network. The company addresses some of its challenges, as well, including its delays in Systems on Chip (SoC) development progress, its diminished operating margins, competitive challenges in China, and an acknowledgement of increased price competition in the 5G era. We focus our writeup on two main topics: Enterprise and semiconductors.
Enterprise. The company leads with private LTE in selling to mostly outdoor environments where mobility needs are key. Nokia calls these networks “private wireless.” Generally, the target companies are those that are asset-intensive businesses, and Nokia has no current plans to go down-market. Nokia has sold to 120 enterprise customers as of September 2019, up from 80 as of June 2019.
Semiconductors. The company discussed semiconductors at great length at the meeting. Here is a summary of the main chips that were discussed.
Big themes at the show were WiFi-6, 6 GHz, and 802.11ah. We share some comments about the following organizations: WiFi Alliance, Commscope, Newracomm, Celeno, Cambium, Juniper Networks, On Semiconductor, Extreme Networks, Webb Search, Facebook, UK's Ofcom, Huawei, and 650 Group.
The WiFi Alliance and a handful of other speakers commented that WiFi-6 has lower latency than 5G, but the Alliance conceded that cellular had better mobility. We think the WiFi community is not doing enough to promote WiFi-6’s low latency capabilities
Commscope expects 6 GHz 802.11ax products to be shown at the CES show in January 2020 and that FEM and filters are not available today but will be by year-end or early 2020.
Newracomm is an 802.11ah (900 MHz WiFi) chip company that had won an award at the show. It claims to be an early leader in the market and based on comments made during presentations, we expect by 2H20, we will see systems and IoT services based on these types of chips.
Celeno, a stand-alone WiFi chip company, demonstrated radar on WiFi chip capability - the company won multiple award at the show. The company expects that a year from now, its Doppler on WiFi will emerge in products from SPs such as BT, Orange, and Comcast. The Doppler service only consumes about 3-5% of throughput capability when using Doppler and enables some very interesting capabilities such as fall detection, proximity detection, people counting and arm gestures.
ON Semiconductor's Quantenna group won an award at the show.
Cambium, in a presentation, explained that it is looking at an expansion to CBRS, 5G FWA backhaul, and 60 GHz.
Juniper Networks has been hiring in Europe as it expands its enterprise sales capabilities. It’s recently hired team made a positive impression on the audience. We tweeted about how great and fun the presentation by recent hire Jussi Nivikiemi’s presentation.
Extreme Networks presented its view that Artificial Intelligence won’t replace IT workers - it will just make them better.
A spectrum consultant - Webb Search - said that DFS is not working in the UK in 5 GHz and wastes a lot of bandwidth - most WiFi products don’t bother trying to operate one the spectrum covered by DFS. He advocated for using a database in the sky approach similar to what is being proposed for 6 GHz.
UK's Ofcom representative, Christina Data, explained that it is researching both 5 GHz and 6 GHz as a comprehensive solution. Ms. Data acknowledged that DFS may have some challenges and was diplomatic in response to questions about how 6 GHz will emerge.
Huawei advocated for an unpopular viewpoint (at a WiFi show) that 6 GHz device makers should register for IMT designation. In a panel that included German WiFi equipment vendor Lancom and Commscope, the other two vendors made counterpoints, including that this move to IMT will delay the rollout of 6 GHz by at least four years.
Facebook is advocating a non-AFC approach to low power 6 GHz in the US market. We have learned through multiple sources that it has recently a demonstrated a prototype of an AFC, however.
650 Group. The Chris DePuy presentation hit on three topics: unlicensed and shared spectrum impact on WiFi, WiFi and WiFi-6 shipments, and WiFi semiconductors.
We attended the Mavenir analyst meeting last week. The company has made progress in developing its radio products, while at the same time it has grown revenues approximately 15% this year and bookings are estimated to reach $510M this year. The company expects to achieve a 28% EBITDA margin this year, greater than last year’s profitability rate. The company has 3,100 full time employees, up significantly from last year. We met executives hired recently with impressive pedigrees. The company is positioning itself as a US based end-to-end mobile network operator supplier.
In 2019, most of the company’s revenues are from the telecom core products. Generally, the company is taking a software-only approach to the mobile network market, which in many ways is what operators want from its suppliers. By taking a software-only approach, the company leaves some of its destiny in the hands of others, especially when it comes to hardware acceleration and radio units.
The company has achieved success in VoLTE and RCS. It is using the growing brand it has developed in these telecom core services areas to get access to RAN projects. The company describes its RAN activities and its partner’s radio capabilities as being able to handle radio connection densities on the order of 200 users per radio.
Mavenir plans to bring User Plane Forwarding capabilities for packet core to market next year with hardware acceleration; chip suppliers that were mentioned include Intel and Mellanox (now Nvidia). The company is investigating various acceleration techniques such as GPU, ARM and FPGA, which presumably will allow the company to provide a denser baseband system than is currently possible.
The company is targeting mobile operators that are making initial deployments of O-RAN based radio systems. Mavenir explained that European RFIs are allocating a certain number of RAN sites to O-RAN. The company claims to have recently been awarded some O-RAN contracts that have limited deployment scenarios. Vodafone CEO made public statements in support of working with Mavenir recently.
ORAN and CBRS were the main themes at Mobile World Congress Americas, held in Los Angeles. I have to say, though, that unlicensed was the third most important theme, though it will emerge to the main stage in future years.
ORAN encompasses several topics woven together. ORAN is a set of common interfaces that describe how various devices in mobile RAN work together. ORAN may also represent a new way of building radio networks. Recently, new vendors are being invited to bid on major mobile network projects, including Mavenir, Altiostar, Parallel and others. And, the major market share players in mobile RAN, which include Ericsson, Nokia, Huawei, Samsung, and ZTE are being asked by operators to support ORAN. The incumbent vendors are responding in various ways: Samsung, a challenger in the market, has whole-heartedly embraced ORAN, while Huawei has only recently acknowledged the existence of ORAN. Ericsson and Nokia have embraced ORAN with the view to embrace and extend - in the sense that Microsoft used this term in the 1990s. Based on presentations made by Ericsson, Nokia, and Samsung, we expect that the incumbents, Ericsson and Nokia,will embrace ORAN but will establish a path to continue serving customers with the same vertically integrated business models of today. We are eager to see the results of mobile network operator bidding to observe how many startups win projects for wide scale deployment.
CBRS. Today, CBRS is available in the US market and has been so for about a month. We had an interesting opportunity to moderate three panels on the stage at MWCa and found some very interesting indoor/campus uses for CBRS, including WiFi backhaul, secure/critical communications, surveillance, IoT/sensor monitoring. Since CBRS indoor spectrum generally allows for more output power than for WiFi, the range is better. We see this as a key advantage for CBRS users, though enterprises who take advantage of the so-called OnGo service must pay various monthly fees such as those for the SAS and potentially other ongoing services. We expect that CBRS will be successful in certain verticals.
Unlicensed. We believe the existence of CBRS could uncork the value of unlicensed spectrum at 900 MHz, 5 GHz, 2.4 GHz, and 6 GHz. We are conducting significant research into each of these and other spectrums.
Aruba, a Hewlett Packard Enterprise company’s new CX 6300/6400 switch launch was significant for the industry. The launch ushered in next-generation enterprise switches at the second-largest vendor in the world using its custom, 7th generation ASICs, along with updates to the operating system. HPE Aruba’s products are high-end, clearly targeting large enterprises. By offering one end-to-end portfolio, HPE Aruba will be able to target additional parts of the campus market, increasing its addressable market and simplify the product offerings.
High-speed multigig ports and uplinks and robust stacking allow for the support of WiFi 6 and beyond along with a nimble approach to many new IoT use cases connecting to campus switches. For example, the switches can be rebooted without the devices connected to the PoE port losing power (always-on POE), a perfect feature for industrial use cases like lighting and IoT sensors.
As we look at the future of networking on the campus, the ability to automate (eventually with full AI-control) is necessary to allow the human to scale with the number of and diversity of devices entering the campus. Campus switching is moving more into an infrastructure and supportive role with a diversity of connections beyond just IP Phones and desktop PCs.
In North America, as large enterprise campus network spends starts to plateau, and mid-market continues to grow, this will cause the vendor landscape to shift fairly significantly compared to what the market has historically seen. With HPE Aruba’s new products shipping later this year, we expect 2020 to be an exciting year of change in the campus.
We attended the operator and vendor consortium of 5G Americas. The themes of the show were: 5G, spectrum, cell siting, Asia-Pacific operator progress. For the second time in the past couple weeks, we saw FCC Commissioner Michael O'Reilly present, and his key messages were similar both times, focusing on CBRS, C-Band and 6 GHz. In attendance from the North American service provider side were AT&T, T-Mobile US, Shaw, and Sprint (we focused on NA operators mainly in this write-up). Notable vendors included Cisco, Commscope, Ericsson, Intel, Kathrein, Mavenir, Nokia, Qualcomm, and Samsung. We would say the most important theme from the show is the surge in interest in unlicensed spectrum, both for the use of mobile operators, as well as competing carriers, as well as by enterprises both for indoor and outdoor applications. For this write-up, we are focusing primarily on comments made by some of the leading operators who attended the conference.
AT&T discussed mmWave, future 3GPP releases, 5G phones, Mobile Edge Computing and indoor cellular, mid-band spectrum strategies, 5 GHz spectrum usage, Mobile Edge Computing (MEC), StandAlone (SA), among other topics. AT&T views mmWave as just a tool in the toolkit, so to speak, and not the only spectrum that is useful in 5G. It considers mmWave to be most helpful in urban and potentially indoor settings. Representatives said that future 5G-oriented Releases 16 & 17 are expected to be software upgrades to existing hardware and won't require new equipment to incorporate these new capabilities which will include network slicing. AT&T is making a big deal about its Mobile Edge Computing (MEC) initiative. At the conference, it emphasized MEC as having two main parts: a) expansion to about 100 edge sites (mostly Central Offices) from about 20 central locations in the LTE era and initially supporting packet core, and b) Microsoft Azure services managed end-to-end by AT&t. The company also emphasized that it plans to pursue some indoor cellular opportunities, some that currently leverage 5 GHz using LAA technology, some that will leverage CBRS and some that will leverage mmWave. We get the impression from AT&T that it is open in how it pursues future mid-band spectrum strategies. Its strategy could change based on: a) the timing of the CBRS PAL licenses (currently slated for June 25, 2020), b) the potential for C-Band private auctions (potentially in the mid 2020 timeframe), c) the potential for some or all of the 6 GHz spectrum availability (where Wi-Fi 6 would co-occupy), as well as other factors. We learned that, at least in certain regions, the company is making very ample use of 5 GHz spectrum using LAA techniques. AT&T seeing its picocells (small cells) get around 100 Mbps from LAA out of a total 130 Mbps inclusive of around three other licensed spectrums. We were surprised the company makes such ample use of unlicensed spectrum where Wi-Fi currently exists. The 5 GHz experience of AT&T leads us to think that 6 GHz, which promises to offer far more spectrum that the 5 GHz swath presently available, could be very beneficial to mobile operators and their consumers, as well as the Wi-Fi industry, and its consumers. AT&T expects that by this time next year, it will be "pushing" 5G to all its customers, part as a result of handsets adopting 5G capabilities, part the result of its network seeing nationwide coverage. Of the services that AT&T operates, it is installing mainly Packet Core in its MEC systems. AT&T is also planning to run Microsoft Azure services in its MEC locations. It expects that both Packet Core and Azure will see a 10-20 ms latency reduction by being located in MEC locations. AT&T says that StandAlone (SA) is "just new software," and downplayed the significance of the upgrade from EPC/NonStandAlone (NSA) to SA.
Sprint "is all-in on 2.5 GHz mid-band deployments for 5G services." Given the company's potential merger with T-Mobile USA, we view its network-build-out choices as being somewhat limited. It has limited options because it increases its near-term value to its acquirer, T-Mobile, if it deploys 5G in 2.5 GHz. Likewise, it is doesn't implement in mmWave, this reduces overlap with T-Mobile, who is deploying there. The company reiterated that it had launched 5G in 9 markets. It is seeing its peak speeds on 5G (aided by the fact that it has simultaneously upgraded hardware to Massive MIMO) be about 3-5 times that of its 8T8R LTE systems. It currently covers 11M POPs and 2,100 square miles with 5G. Sprint also shared that it sees RFPs from customers to replace Wi-Fi with 5G, though it didn't share more about this topic. The company's experience is that in upgrading its macro base stations to Massive MIMO 64T64R capabilities, it is getting 3-4x faster throughput than its 8T8R systems, though in the field these measurements vary widely. Additionally, Sprint said that its Massive MIMO systems relative to earlier systems show "generally the same coverage," with 1-2 dB better sometimes. Sprint is exploring ORAN and vRAN but "not adopting near term."
Shaw (Canada) presented its mobile LTE and 5G efforts and plans. Shaws plans are interesting because the company has significant cable services deployed in Canada. The company said nearly all the mobile technology it has installed in the past three years are "5G-ready." It will use 5G first in 600 MHz, then in mid-band (probably in 3.5 GHz) and the last in mmWave. Shaw expects that low-band 5G handsets will be available in 2020, and, similar to what AT&T said, it expects that is when 5G mobile will start in earnest in Canada. Shaw admitted that it is behind where the US operators are in deploying 5G, but offered no apologies, as it felt it is where it needs to be from a competitive standpoint in Canada. Almost laughing, Shaw explained that it would never consider deploying mmWave along highways, and that only high-density locations would get mmWave coverage. Shaw's view that mmWave is for high-density locations was shared universally by other operators in attendance, including AT&T, Sprint and T-Mobile US.
T-Mobile US spokespersons explained that mmWave has seen some challenges, relative to initial expectations and that while it does get mmWave to operate beyond near-line-of-sight, the view of T-Mobile is that mmWave is "just part of 5G." T-Mobile expects 3GPP Release 16 to be completed in 2020, but that it will be 2021 before it deploys Release 16, which won't require "a massive hardware refresh" and which will incorporate industrial and connected vehicles features. T-Mobile views 5G as being appropriate for indoor installations because while mmWave has challenges penetrating glass and concrete, but when 5G operates in low and mid-band spectrums, the "issue goes away." By 2020, T-Mobile expects StandAlone packet core to be ready, but since its current EPC/NonStandAlone (NSA) systems are already virtualized, the upgrade to SA is "not a forklift" upgrade. T-Mobile says virtual RAN (vRAN) "will take time," and that it will "need accelerators," which we take to mean FPGA-based Network Interface Cards (NICs) or the like to allow servers to operate faster than just x86 processors will allow.
We attended the CBRS Alliance event in Washington DC today, and by our rough estimate, about 350-400 people were in attendance representing groups such as regulators, legislators, lawyers, technology vendors, property owners, service providers, investors, media and analysts. We were impressed with the widespread interest in the new shared spectrum technology and services running in the 3.5 GHz band that is now called “OnGo.” We have researched CBRS for many years and found several acronyms and CBRS-specific terminology to be blossoming. We found several themes at the CBRS Alliance event and a follow-on event at Federated Wireless, a SAS service provider, of special note: a) the OnGo experience will serve as a mold for regulators, operators and other interested parties not just in the US, but also the rest of the world, b) Tier 1 operators and WISPs appear focused on Fixed Wireless Access (FWA) deployments in CBRS spectrum, at least initially, c) many presenters focused on the “OnGo backhaul to gateways” use-case, at least as an initial opportunity, d) interested parties have a concern that PAL licenses may become very expensive when the auctions occur, and e) there were a very large number of devices supporting OnGo at this event.
Acronym soup. The CBRS Alliance did its best to explain the various acronyms and how the various players work together. It would take at least six pages to cover just the top-level details. The idea here is that the 150 MHz of spectrum in the 3.5 GHz range was previously used exclusively by the US Department of Defense and is now going to be shared using a three-tier process, where the military (the incumbent) will have use of it when it needs, then private license holders will get next dibs (PAL), followed by general users (GAA). Starting today, GAA users will begin use of the spectrum in the Initial Commercial Deployment (ICD) that was announced today, starting at 9 AM Eastern. A group of service providers called Spectrum Access System (SAS) providers have been authorized to install radios on the US coastline that sense when the military is using the spectrum and send channel-use information to equipment that is operating in the CBRS spectrum. These SAS providers will, therefore, coordinate the frequencies between incumbent, PAL, and GAA users.
Our view on why OnGo and “Shared spectrum” matters. We expect that by sharing spectrum amongst various parties, more traffic can move across a smaller range of frequency than by using the more common method of auctioning off frequency bands to be used exclusively by one entity. We estimate that shared frequency will carry ten-times more traffic than frequency bands licensed for the exclusive use of single entities. Thus, it is for the greater good that this OnGo / CBRS experience go the distance and allow a public demonstration of whether multi-tiered shared spectrum can succeed or not. Already, we have the experience of shared spectrum in the 2.4 GHz and 5 GHz bands used by WiFi – there is no doubt this has been successful; in fact, most public estimates show about 80% of smartphone traffic is carried by WiFi rather than cellular systems, all of which as of yesterday was carried on licensed spectrum. At the CBRS Alliance event, guest speaker, US FCC Commissioner Michael P. O’Reilly said that based on the success of OnGo, he expects similar models could be applied to additional spectrum (and he implied this might the sequential order of launch): C-band (3.7-4.2 GHz), 3.45-3.55 GHz, 3.1-3.45 GHz and 7 GHz (which we understand is meant to be the same thing as what is being discussed at 6 GHz by the WiFi community).
FWA opportunity is front and center. Charter and AT&T focused their comments on their plans to deploy fixed broadband systems. AT&T shared some impressive statistics about the performance of recent trials using Massive MIMO cell sites using distributed RAN over CBRS spectrum, which is connected to indoor baseband over fiber optics to the radio sites and then connects wirelessly to customer premises equipment mounted at the roofline: it said it achieved 140x12 Mbps at slightly over one mile over line of sight using 20 Mhz channels. Charter discussed it had deployed its first commercial FWA in Davidson City, NC to rural locations. It also discussed how it uses dual SIM systems to allow customer coverage to Verizon’s cellular network. Charter also discussed private LTE, neutral host, and Industrial IoT use cases. The Wireless Internet Service Provider’s Association (WISPA) President spoke about its members’ enthusiasm for OnGo and explained that 100’s of WISPs used the 3.65 GHz spectrum and expects more will use the 3.5 GHz / CBRS spectrum. Currently, WISPA says WISPS in the US have 6 million customers.
OnGo as a backhaul. We detected a theme that seems durable: CBRS spectrum can be used by enterprises with far-flung operations to save costs by reducing the installation of wired / optical cables and associated infrastructure. There was an impressive list of vendors who had equipment at the show, a number of which were gateway devices that made connections between CBRS and other well-known protocols such as Ethernet and WiFi, to name a couple. While OnGo/CBRS support is not as widespread on devices today, IoT devices supporting other wired and wireless systems certainly are, the list of which includes WiFi, Zigbee, Bluetooth, Ethernet and more. We were taken by how compelling some presenters made a case for using CBRS simply assuming a reduction in new cabling to enable new systems such as kiosks, surveillance, digital signage, farming, and so on. Many of these examples would increase the deployment of existing protocols like WiFi, Zigbee, Bluetooth, and Ethernet, instead of reducing their demand. The idea that OnGo/CBRS competes with existing systems may be incorrect.
PAL auctions. Commissioner O’Reilly said PAL auctions are scheduled for June 25, 2020. In our formal and informal interviews, we understand there is a growing concern that CBRS spectrum auctions could be aggressively pursued not only by existing Tier 1 mobile operators but also by other players, not least of which could include MSOs and maybe even “Big Tech” companies. Since the 3.5 GHz spectrum is where many countries besides the US have begun deploying 5G services, making equipment in these frequency bands commonplace, there is ample reason to want to use this spectrum in the US. Bidders may raise the price high enough that enterprises will choose not to compete, and won’t view the CBRS spectrum as attractive as they had hoped. In this case, PAL would look quite a bit more like a typical licensed spectrum, similar to other auctions.
OnGo devices abound. At the show, the following vendors had devices on show (see pictures): Sercomm, MultiTech, Sierra WIreless, Zyxel, Encore, Cradlepoint, AMIT Wireless, Commscope / Ruckus, Accelleran, Bai Cells, Cambium, Samsung, Google, LG Electronics, Sequans, Telit, JMA Wireless, Motorola Solutions, Cisco, BEC Technologies, Ericsson, ip access, BLINQ, Comba Telecom, and Westell.
