The Party-Crashers of MWC21

6/30/2021

0 Comments

 
This week's MWC Barcelona 2021 had several themes; the most important was that several outsiders to the telecom industry were ever-present.  The new entrants – the party-crashers - included Starlink, Microsoft Azure, Amazon Web Services, Google Compute, and NVidia.  These new players are forcing change either through economics, new technology, or new regulatory frameworks, or combinations thereof.  We’ll touch on the importance of these crashers and then circle back to a few other ongoing themes that continue to remain relevant in this article.

Satellite broadband, while not exactly a mobile technology, will catalyze significant changes to the mobile industry.  Low Earth Orbit (LEO) satellite services, evangelized today by SpaceX-owned Starlink, announced plans to spend as much as $30B in building out its constellation over its lifespan. Yet, it will reach users across the globe.  Elon Musk said Starlink is in beta in 12 countries, and it plans to have ½-million users in the next 12 months.  The billionaire highlighted that Starlink’s ability to reach rural populations is unlike that of terrestrial players.  We think the rural reach of LEO broadband is precisely why Starlink will be so important.  Musk’s pitch to the mobile industry was that of a partnership – he said that Starlink is partnering with 5G MNOs to offer satellite backhaul and rural broadband services.  We view satellite broadband, and later 3GPP satellite, as critical components in the telecommunications industry, and therefore we chose to write about satellite first in this article.

All three hyperscalers, Azure, AWS, and GCP, made a splash at MWC21.  As a group, these infrastructure providers have already changed the way telcos operate.  In fact, the hyperscalers’ architectures were the inspiration behind the decade-old telco push for Network Functions Virtualization (NFV).  But, these days, hyperscalers’ operations are more than an inspiration to the telcos.  MNOs are now moving some of their workloads to hyperscaler infrastructures.  The evolution of these workload migrations to hyperscalers is moving in three phases, phase 1, the back-office, then phase 2, telecom core, and last, phase 3, the access layer. In the weeks leading up to MWC21, we’ve seen progress on all three workload migrations, including that on Mobile RAN.  Incoming AWS CEO Adam Selipsky said at MWC that AWS is talking to “virtually every telecom operator.” 

​Some examples of announcements made surrounding the MWC show include:
  • Phase 1: AWS / Verizon various relationships, AWS / Netcracker (NEC) relationship
  • Phase 2: AT&T is moving 5G/4G core to Azure (inside of AT&T facilities)
  • Phase 3: GCP / Ericsson relationship

With Open RAN capabilities come the possibility that MNOs can source various RAN components from multiple vendors.  Rakuten has already technically demonstrated multi-vendor sourcing (Altiostar baseband and Nokia and NEC radios).  In addition to system-level multi-vendor interoperability, in previous years, multiple semiconductor companies had been bolstering their RAN offerings (Marvell, Qualcomm, EdgeQ).  Marvell had previously crashed MWC (MWC19 and MWC20) and is now a RAN supplier to Samsung and Nokia.  For MWC21, we saw yet another entrant to the RAN chip market, NVidia.  NVidia has received pubic endorsements from Ericsson, Fujitsu, Mavenir, and Radisys.  NVidia’s current chip offering is called “AI-on-5G,” and the company’s offering starts in 2021 as an “on a server.” NVidia’s next offering is expected in the 2022-2023 era and will be an “on a card” offering.  Then, after 2024, NVidia will offer its “on a chip” offering.

Qualcomm MWC20 announcements include Updates on 5G, Wi-Fi 6E and mmWave

2/25/2020

Qualcomm made many wireless-related announcements today from its San Diego, CA headquarters, in place of making a presentation at #MWC20 in Barcelona.  Top announcements included its FSM100xx 5G small cell chips customer announcements, RF-chip availability, Wi-Fi 6E demonstrations, and 5G smartphone customer announcements.
​
FSM100xx 5G RAN endorsements.  Qualcomm announced its FSM 5G RAN platform in May 2018, targeting small cells and remote radio heads and enabling bothmmWave and sub-6 GHz spectrum using 10 nm process geometry.  The company listed multiple vendors and operators in its press announcement relating to FMS100xx chips.  Each of the vendors shared some interesting statistics, the most important of which we share here:
  • Airspan is using FSM products in developing its small cell products and base stations.  The company’s CEO said, “we are on track to deliver tens of thousands of 5G base stations in [the] field in 2020.”
  • Altiostar, an Open vRAN software maker well-known for its win at Japan’s competitive mobile operator, Rakuten, announced a year-ago at #MWC19, said that the performance of its vRAN and Qualcomm’s 5G RAN platform will allow operators to build carrier-grade high performance RAN. 
  • Baicells plans to use Qualcomm’s 5G RAN platform chips to serve “vertical industries” using small and easily deployable infrastructure.
  • Corning has a working relationship with Qualcomm on 5G mmWave RAN and plans bring “open platforms” to indoor spaces.
  • Radisys, Rakuten, Small Cell Forum endorsed Qualcomm, as well, without too many specifics.
  • Samsung has expanded its 5G product set, using Qualcomm 5G RAN platform, to “in-building and outdoor hotspots.”
  • Sercomm plans to use Qualcomm 5G RAN platforms in its products to serve mobile network operators with 5G small cells.
  • T&W has used the FSM90xx and FSM99x to deliver “over 100,000” 4G RAN small cells for leading operators.  Using FSM10xxx, T&W expects to provide Tier 1 operators with its 5G small cells on both sub-6 GHz and mmWave bands.
  • Verizon endorsed the use of Qualcomm based small cells, as well as the “incorporation of virtualization and open interfaces.”

​Qualcomm ultraSAW Filter.  Expect availability in 2H20.  Hit parity in performance in 2019 and now claims that its ultraSAW Filter will exceed performance of competitors, especially in high-bands.

​Wi-Fi 6E.  Qualcomm demonstrated 6 GHz operation between its Networking Pro Series (Wi-Fi 6 chips for Wi-Fi infrastructure like access points and routers).  Qualcomm was not specific about the timetable for delivery of 6 GHz systems, but the company hinted that the 6 GHz demonstration “underscores Qualcomm’s readiness to extend its successful Wi-Fi 6 portfolio into the 6 GHz band for a transformative Wi-Fi 6E performance, pending regulatory approval.”  The company expects that mobile devices using its Snapdragon 865 Mobile chips (intended for user devices like smartphones) can operate more than 3 Gbps when using the new 6 GHz spectrum, or 1.8 Gbps when using existing 2.4 GHz and 5 GHz available today.  Qualcomm said its Networking Pro Series (Wi-Fi 6 chips) have been “deployed in more than 200 designs shipping or in development.”

Qualcomm Snapdragon 865 Mobile Platform.  The company announced that its chip system for mobile phones that features its second-generation 5G Modem-RF system, the Snapdragon X55, has been “announced or are in development” in over 70 designs, including those from top vendors such as OPPO, Samsung, Xiaomi and ZTE.

​Additionally, the company made VR devices and Personal Computer (PC) announcements including partners such as Facebook (VR) and Microsoft (PC).

Mobile World Congress Americas Themes: ORAN, CBRS and Unlicsned

11/4/2019

0 Comments

 
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.

5G Americas conference: unlicensed spectrum highlight

9/30/2019

0 Comments

 
​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.

CBRS Alliance event marks the launch of OnGo and Initial Commercial Deployment

9/18/2019

0 Comments

 
​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.

Huawei's Chip Projects Front and Center at Analyst Summit (HAS2019)

4/22/2019

0 Comments

 
Huawei hosted 700 analysts and media participants in Shenzhen China last week to attend its annual analyst summit, nick-named HAS2019.  The company's high-level message was simple - the company is an innovator and is moving down the stack into semiconductors and is partnering with and funding university projects to develop basic research.  This year’s message was different from than the prior-year meeting, but several transformative events have occurred between this meeting and the prior year's, most notably the 2Q18 shipment ban on ZTE, the US / China trade dispute and US efforts to thwart Huawei’s participation in the 5G infrastructure of its allies.  Interestingly, during HAS2019, the Apple and Qualcomm announced their chip-supply and patent settlement, Samsung announced its foldable phone (which has been met with criticism), and Ericsson & Swisscom announced that the operator went live with its 5G network.  All three of non-Huawei events highlighted the importance of Huawei’s chips and innovation announcements.

The company made announcements in its main keynote presentations on day one about seven different chip projects delivered recently or planned shortly.  Chip-level is unusual for what are typically high-level presentations from a keynote-level presentation.  These chips (seen in accompanying pictures) are:
  • Ascend 310/910.  Artificial Intelligence (AI) chip for cloud (leads to its Data Center Ethernet Switch iLossLess cloud service)
  • OptiXtreme H6 oDSP.  Optical transmission Digital Signal Processor (DSP).
  • Hi 1822.  FC/IP chip used for products including Solid State Drives (SSDs)
  • Atlas 200 AI acceleration for AI computing intended for September 2019 announcements at Huawei Connect
  • Tiangang 5G Basestation chipset
  • Balong chip series intended for 5G smartphones and other Customer Premises Equipment (CPE)
  • Kungpeng ARM chips for computing
The company shared more details about other chips in breakout sessions on the second and third days of the conference, as well.  The point we are making, though, is that upper-level management provided significant detail about semiconductor developments at Huawei.

Huawei 5G baseband, 5G Core and antenna product line at HAS2019
The company shared more details about other chips in breakout sessions on the second and third days of the conference, as well.  The point we are making, though, is that upper-level management provided significant detail about semiconductor developments at Huawei.  Another relevant semiconductor-related point to make is that the company is de-emphasizing its reliance on Intel-based architecture and instead is focusing on devices such as ARM-based processors, as well as GPU, FPGA and NPU semiconductors.
We would be remiss if we did not mention some of the system-level announcements and observations related to 5G that were made at the HAS2019 conference, which include:
  • MU-MIMO.  Of Huawei’s 70,000 shipments of 5G base stations as of the show, 97% were MU-MIMO based.  The company expects MU-MIMO to be deployed not only in urban areas but also in rural areas.
  • SingleRAN Pro.  The company is taking an architectural approach that is different from what some service providers in the world want; it is delivering an integrated product approach where multiple frequencies and base stations are integrated into the same enclosures.  This converged approach is different from the architectural approach being promoted by some smaller vendors like Altiostar, Mavenir and Parallel Wireless, which uses the O-RAN standard and features a disaggregation between various components like antenna and base band processing.  Huawei’s rationale is that it is less expensive on capital spending and operational spending to use the integrated approach.
  • Converged Mobile Packet Core.  The company plans to have 1H19 commercial availability of its 2G/3G/4G/5G NSA/5G SA packet core system.  In slides depicting this product, it prominently features chip systems such as GPU, FPGA, NPU, and ARM but specifically excludes x86 references. 
  • Huawei expects to deliver its first 5G phone in November 2019

Mobile World Congress Americas (MWCa) And AT&T Spark - All About 5G

9/14/2018

0 Comments

 
We attended Mobile World Congress Americas (MWCa) in Los Angeles, CA this week, as well as the AT&T Spark event in San Francisco.  Since 5G is launching first the US, these two events became the public events where significant 5G-related announcements happened.
  • Verizon.  Will launch 5G Fixed Wireless Access (FWA) on October 1 in four markets: Houston, Indianapolis, Los Angeles and Sacramento.
  • AT&T.  The company reiterated its own 5G plans (mobile 5G by year-end 2018 in cities such as Atlanta, Charlotte, Dallas, Indianapolis, Oklahoma City, Raleigh, Waco, Houston, Jacksonville, Lousville, New Orleans and San Antonia), plus it made some announcements like that it is beginning 5G-ready CBRS equipment testing (using Samsung CBRS equipment and CommScope as SAS provider).  Also, at the Spark event on Monday, the company announced three strategic telecom equipment suppliers, Ericsson, Nokia and Samsung. 
  • T-Mobile.  Announced that it had completed a Cisco vEPC system (upgradeable to 5G Core) carrying traffic for 70M users that was from Cisco.  It also announced that it signed a $3.5B 5G agreement with Ericsson.  This is in addition to the July 30 announcement made earlier with Nokia for $3.5B, as well.  Generally, the company has set expectations as recently as September 10 that it will provide nationwide 5G by the year 2020.
  • Sprint.  Announced that it had demonstrated a 5G NR connection of Massive MIMO with Nokia equipment.

Additionally, discussions about spectrum in the US market were very active discussions.  Some points we picked up on:
  • No new mid-band auctions will occur in the US market for another 2-3 years, so this means that new capacity is going to come from LAA (just announced on the iPhone Xs this week, as well) and from CBRS (discussed above).
  • The "who has the fastest 5G throughput" battle will be won at the millimeter wave.  In other words, using millimeter was, speeds as high as 10 Gbps are possible, but with mid-band (1-6 Ghz), where LTE is currently deployed, cannot go much over 2 Gbps.  So, to beat the Ookla Speed Test, the mobile operators who deploy mmWave early will get a leg up.  However, in order to deploy mmWave, these have to be small-cells that are within 100 meters of users.  Since it is so difficult to get real-estate rights and backhaul for small cells, this is going to be a big challenge.  Nevertheless, this is how the battle will be won.
  • T-Mobile's 600 Mhz rollout is now in 1,250 cities.  The company will eventually enable 600 Mhz 5G.  600 Mhz should dramatically improve T-Mobile coverage because it is low-band spectrum.

OCP Summit 2018 - Disaggregation Theme Dominates

3/21/2018

0 Comments

 
The OCP Summit 2018 hit record attendance and we can can summarize the theme as that of continued disaggregation of network/server functions.  Examples of demonstrations, presentations and proposals associated with disaggregation are as follows:
  • Flash/SSD.  Project Denali was presented by Microsoft.  The idea is it separates SSD controller functions from the flash memory itself, allowing the controller to be modified for different work-loads.  This means, essentially, controller semiconductor companies such as Broadcom and Marvell may need to be selling directly to hyperscalers such as Microsoft, as well as to their historical customers - the SSD vendors - such as Western Digital and Samsung, for instance.  We believe other hyperscalers have implemented flash unbundling already.
  • Unbundling of Networking.  Facebook showed off its FBOSS, a network operating system.  Big Switch demostrated its FRR Open Source BGP, a routing protocol and Google showed off its Controller-based P4 system.  There was some levity in this presentation as the hardware upon which the Google system ran was "(not disclosed)" - see accompanying slide.
  • P4 network layer abstraction and programming environment.  Google showed what we believe to be a live, in-production system using P4 to perform route injection and many other functions.
  • Taking the OCP concept a bit further from the traditional server, storage and switch market, Mojo Networks demonstrated an Edgecore-supplied "OCP Accepted" Wireless LAN Access Point that was running the Mojo AP software and working with the Mojo Networks cloud-managed services offering.  This wasn't just a desk unit, the company had 21 live-working Access Points using the OCP concept that powered WiFi to the trade-show floor.
One clear message away from disaggregation was presented and proposed separately both by Facebook and Arista was that for co-packaged optics.  Both companies explained that this integration will consume lower power; Arista went so far as to say it would consume 30% lower power on a system-wide basis.  There was no clear consensus at the show whether co-packaged optics was going to be a hit; however the power-hungry hyperscalers must certainly be entertaining it.
