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.

​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.

We attended the Aruba Atmosphere 2019 user conference in Las Vegas.  What we learned was that Aruba had made solid progress since last year’s Atmosphere conference.  It has delivered on 802.11ax, SD-Branch (and SD-WAN), AI/ML, and Zigbee/Bluetooth 5.0, and elements of the IoT market.  The company also introduced a new access point that was not hinted at last year, an 802.11ad outdoor access point.  If we were to sum up the company’s main message for the show, it’s all about SD-Branch.  The company took great efforts to emphasize that its portfolio has greater breadth than ever and is among the few vendors that can deliver all the networking a company may desire.

802.11ax.  At last year’s event, the company told customers to expect 802.11ax products by Nov/Dec of 2018.  Our market share tables show the company shipped 802.11ax for revenue in 4Q18.  At the show, the company also announced some new, full-featured 802.11ax Access Points, the 530 and 550 series.  These new Access Points support Bluetooth 5 and Zigbee, to allow support of IoT devices.  These new 802.11ax Access Points will be available this month, April 2019.​

802.11ad.  The company also introduced a point to point outdoor access point.  The new AP387 allows 1 Gbps at 400 meters using 802.11ad and has a backup of 5 GHz 802.11ac in case of inclement weather.  This device has been shipping for a “couple months” according to the stage presentation (personnel at the show booth said since January 2019).

Machine Learning.  Using Machine Learning for Client Steering and for managing Transient clients. At last year’s Atmosphere event, the company was just rolling out AI/ML to customers to improve networking capabilities for wireless users. 

SD-Branch.  The company disclosed that it has 25,000 SD-Branch “wins,” which means that it has many contracts to sell “at some point in the future” SD-WAN and other branch equipment systems such as WLAN and switching.  At last year’s event, the company had not sold any SD-WAN, so this is a big accomplishment and signifies Aruba’s progress in delivering what it calls a Single Pane of Glass approach that includes four parts:  SD-WAN orchestration, Dynamic Path Steering, Secure Connectivity, and Dynamic Segmentation.

Clearpass Device Insight.  The company introduced its device recognition system, intended to simplify the discovery of IoT devices on the network.  Clearpass Device Insight is available in April 2019.  This cloud service uses a fingerprint database, as well as AI/ML, to find devices on the network, and then presents them by category on a single screen.

During the day-2 presentations, the company had some fun and CTO, Partha Narasimhan, showed a picture of him pretending to be an IT executive of a fictitious university.

Today I attended the Extreme Analyst day at the NASDAQ in New York. 

Extreme’s 4Q18 switch revenue grew over 10% and in our preliminary view of 4Q18, it took  share.  The company highlighted over 30,000 customers and over 6,000 partners in a one-Extreme approach that has integrated the acquisitions of Avaya and Brocade.

The company also highlighted that in 4Q18 it saw nearly 20 deals over $1M which is indicative of a rebound in its' business from large enterprises.  We believe  the company is  maintaining a good portion of its' Extreme and Avaya installed based.

Extreme  emphasized software as a driver for higher margin sales. We agree, software is the general direction of where campus switching is going with vendors looking to get incremental revenue from software instead of hardware.  We have maintained for over two years now that campus switching would be a positive growth market led by software to help manage a more converged (Unified Access) market.  We also see IoT and the inclusion of securing and monitoring IoT traffic as an additional growth drive for the campus market.
 

Arris held its annual investor day late last week on March 28, 2018.  It was interesting: the company said "Everything is going wireless," which is an interesting admission for a company that, until about a year ago, was essentially a pureplay on wired broadband.  To be sure, the company has diversified into wireless with its acquisition of Ruckus and has benefitted from the inclusion of Wi-Fi capabilities to its broadband CPE.  The company sees this wireless future - and is pivoting towards it.

Arris management highlighted that it expect its future to include the following growth avenues:

• Cloud Wi-Fi
• DELL OEM
• CBRS 3.5 GHz LTE Small Cell
• IoT (Residential and Industrial)
• FTTx (10Gb EPON / NGPON-2)
• Consumer Mesh Wi-Fi
• Campus Ethernet Switching

Additionally, the company discussed its expectations for each division, which using its 2017 mix and various projections, calculates to a 4.7% CAGR from '17 to '21.

Enterprise Networking (Ruckus).  Overall, the company's Enterprise Networking division, also known as Ruckus Networking, includes its Enterprise WLAN business (formerly Ruckus Wireless), the Brocade ICX Ethernet Switch product line (referred to by the company as Campus Switching), and other revenue streams such as CBRS 3.5 Ghz LTE Small Cells, as well as IoT radio modules that plug into the Ruckus Access Points like Bluetooth, LoRa and Zigbee.  The company is targeting 20%+ growth for the Ruckus Networking group, which is far above the industry growth rates we expect for Enterprise plus Outdoor WLAN and Campus switching. This aggressive growth rate either implies share-taking, or growth in other products such as CBRS, Bluetooth, LoRa and Zigbee, or the the non-WLAN parts of what used to be Ruckus Wireless, such as Cloud-managed Wireless LAN services (that, for instance compete with Cisco's Meraki, Aerohive services and Mojo Networks).  The company cited an expected Enterprise WLAN revenue growth projection slightly above our projection for the period '17 to '21, even if cloud-managed WiFi services were included.

​Network and Cloud Segment.  The company said this market is growing 5% annually, and described the market generally as the Cable Modem Infrastructure, optical nodes and cable video networks market.  The company generally expects to take share, compared to this market viewpoint, projecting a 4-7% long-term annual growth expectation for this business segment.  It was interesting that the company said that the "mobile device explosion [is] driving offload demand," because it has been several years since "Wi-Fi offload" was a growth driver, but dissecting the comment a bit more, the company is pointing to cable operators as being "well positioned to handle [the] offload."  We think Arris' strong supplier position with the major Cable MSOs in the US, especially, may indicate that there should be a strong build up of WiFi and cable infrastructure coming in the future.  And, this corroborates with our own research and statements from MSOs such as Comcast.  In fact, the company showed a "future" network diagram that indicates it expects its MSO customers will be delivering 5G radio, Remote OLTs (PON) and Fixed Wireless Access instead the of cable modem (DOCSIS) equipment that was indicated in the "now" chart.  This implied shift from DOCSIS to PON/5G/FWA would be a dramatic shift in the company's product portfolio.  Very interesting, indeed.

Customer Premises Equipment (CPE) Segment.  The company claims a #1 Set Top Box (STB) market share, and #2 Broadband CPE market share, with a mix of 60% video CPE and 40% broadband revenues in 2017.  The company expects to grow broadband CPE to a mix of 50%+ by the year 2021, consistent with the market growth rates it cites - 4% CAGR for broadband and -.8% for video.  Generally, the company is projecting long term sales trend of -5% to +1%, indicating that it lacks the direct to market exposure that would get it to a growth expectation in this segment.  The company confirmed it is using NBASE-T (Multi-Gigabit Ethernet) interfaces on its home networking devices and it is planning to release 802.11ax capabilities on its portfolio, as well.  Arris CPE will also include Extenders / Adapters to, at least partially, address the growth now occurring in the Consumer Mesh market.

This week, we attended the Global Mobile Broadband Forum, held in London, and found several interesting points we thought we would share.  Much of the focus of the conference was about 5G wireless networks, and since the show was in London, many of the service providers who we met with and listened to were European.  The sponsor of this event was Huawei.

• 5G is expected to deliver 10 times the bits per second for each dollar spent compared to LTE.  This is according to Johan Wibergh, CTO of Vodafone. 
• 2 year payback on microcells (small cells).  Telus EVP Eros Spadotto explained that the Canadian operator installed small cells in locations where 10% of traffic was occurring, and shortly after they were installed, these began carrying 30% of traffic.  Telus believes it met untapped demand.  The company views its strategy going forward to be installing more small cells and no more macro sites.
• The 5G timeline appears to be for end of 2018 Fixed Wireless deployments, 2019 mobile trials and 2020 commercial deployment.  We consider the following in assessing this timeline: 
  • According to Huawei, the Chinese government is pressuring China Mobile to be first to deploy 5G Mobile.  Additionally, Huawei's work with radio chip companies leads it to believe that the 5G capable chips that enable smartphones will not be available in early 2018, and its assessment it will take a year to make 5G smartphones once the chips are available, so 2019 is the earliest smarphones can be available.  Huawei says it expects to deliver its own 5G CPE hardware for fixed mobile by later 2018.
  • BT Group CEO Gavin Patterson expects to have 5G commerical in 2020 
  • Deutsche Telecom CTO Dr. Bruno Jacobfeurborn expect 5G in 2020
  • Orange SVP Radio Arnaud Vamparys expects 5G commerical launch in mid 2020
  • Telefonica CTO, CIO Enrique Blanco expects 5G not before 2020
  • Softbank VP Mobil Networks Makoto Noda expects 5G in 2020 before the Olympic Games
  • NTT DoCoMo CTO Hiroshi Nakomura expects 5G to be commerically ready in early 2020.
• Huawei said millimeter wave 5G won't be used for outdoor mobile, only potentially indoor and fixed wireless.  28 Ghz and similar frequencies are not suited for weather and obstacles, according to the company.
• Huawei, like others large vendors, expects cellular baseband processing for the lower layers (PHY and MAC) will remain a specialized hardware function.  However, higher layer functions such as cell selection may end up in virtualized systems running CPUs.  We heard similar viewpoints from baseband processor company, Caviuum, at the MWC Americas show a couple months earlier.
• Tower sharing is a major trend for the future.  All things being equal, as tower infrastructure gets shared by multiple operators, this reduces capital spending.  We expect tower sharing to be a major trend, which will put pressure on capex for many years to come.
• There are two camps in 5G, largely surrounding spectrum and major vendors.  The first camp are Western vendors (Nokia and Ericsson) and the US operators, who seem to be embracing relatively low frequencies for 5G as well as millimeter wave, and then there is the 3.5 Ghz frequency camp, which has suporters in China, Europe and major vendor, Huawei.  We realize this may be an oversimplification of the industry dynamics, but there's a case to be made that China + Europe may end up with a supply chain somewhat unique from the US-centric chain.
• IoT is a major trend, and from what we heard from most operators is it'll be running on LTE for a long time, despite how 5G is expected to be a big IoT capable network.  
• 5G business case still not there yet.  Most European operators are saying they haven't seen a compelling business case to deploy 5G yet (BT, DT, Orange) and Telefonic said it'll deploy 5G when it needs to competitively.
• Fiber good.  Microwave not mentioned.  Every European carrier that we met or who spoke with (plus Telus in Canada) expects to deploy fiber to cell sites and made no mention of microwave.
