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.

Yesterday, Ericsson and Juniper announced plans to partner to tackle 5G transport challenges together.  Additionally, Ericsson announced a partnership with optical transport company, ECI.  The companies said that Ericsson's Router 6000 product family will focus on fronthaul and backhaul and edge compute and will be complemented by Juniper MX, PTX and SRX Series portfolios providing edge, core and security capabilities.  Additionally, in today's presentation to analysts, Ericsson showed that the overall transport capability from Ericsson will also include Optical Transport from both ECI Telecom and Ciena.  The Ericsson Network Manager will be capable of managing not only Ericsson products, but also the three families of products from Juniper.

ECI will be used for Metro, and will be completely integrated with the Ericsson OSS platform.  The company conceded that it is de-emphasizing its in-house metro optical product line and focusing on ECI.  Ciena will be used for long-haul transport predominantly, mainly the Ciena 6500 product.  Ericsson concedes that both ECI and Ciena products can move to other domains.

To enable automation for 5G, Ericsson can only guarantee that networks working with Ericsson and its partners can successfully be automated.  This automation / partnership topic illustrates just how complex it will be to make 5G networks work properly.

Recall that Ericsson and Juniper had a close partnership that goes back many years.  In fact, the Juniper router predecessor to the MX was used as the underlying hardware for Ericsson's very important GGSN/SGSN and later EPC capabilities. Ericsson eventually replaced the Juniper product for EPC with its own Router 6000.  Subsequently, Ericsson announced a partnership with Cisco, which was more general in nature.  That relationship did not result in much tangible progress, from what we have learned; and the relationship was done under previous management teams for both Cisco and Ericsson.  Ericsson explained today in its analyst briefing that Cisco and Ericsson compete in several areas.  So, this new Juniper relationship is important in that it re-kindles an old relationship and plays to both companies' strengths.

​The main theme of the the Huawei HAS 2018 meeting keynotes was Artificial Intelligence and, secondarily, nearly ubiquitous networks connections across the world.  Huawei expects 86% of enterprises to have experimented with AI by 2025 (<5% in 2018).  It is leveraging AI across nearly all its products and will offer a full stack AI solution to all Huawei partners at its @Huawei Connect 2018 conference (Oct 10, 2018).

More specifcially, Huawei is using AI to elevate products & solutions to new levels: cloud, networks, devices, EI, SoftCOM AI, and Intelligent phones.  The company's strategy has changed over time and is now AI-focused:

2006-2011: Single strategy: All IP
2012-2017: SoftCOM: All Cloud
2017+:     All Intelligence: SoftCom AI (autonomous networks / services 2.0) - this reduces operating and maintence costs

The company expects that networks will be 10x more efficient in the operation of equipment as a result of AI.  

By 2025, Huawei expects 440M AR/VR users, 40% of cars to be 'connected," 80% of users with access to mobile broadband, usage of 1 Gbps / user / day (versus .03 in 2018) and 20B connected devices worldwide.


Connected Devices Forecast (Huawei) by 2025: 40B sensors and 100B connections.  This thinking is based on data including that there are: 

• 4B livestock in the world
• 300m streetlights
• 1.8B utility meters
• numerous bike programs in major cities
• numerous greenhouses

The company's product lines are very diverse; to wit, the company introduced a helmet for the blind, which will be available soon.  

Huawei expects NB-IoT (LTE-based IoT capability) to reach almost full coverage in China in 2018.  Additionally, the company expects NB-IoT to reach 100 networks by the end of 2018 (versus 39 in 2017) and to be available on 1.2M base stations (from 0.5M in 2017) and to be connected to 150M connections (versus 10M in 2017).  

The company boasted about several developments:

1. Chipsets for cloud data center systems.  The company highlighted its internally developed Atlas (intelligent cloud hardware).
2. The company expects its cloud services will become one of major 5 clouds.  Uses smart NICs for CPU optimization and is 'open.'
3. The cloud service from Huawei will be low cost because Huawei makes all the equipment necessary to build this cloud
4. Internet of Vehicles system was was built for Group PSA (French auto company known for the Peugot brand)
5. 5-An example of the company's "Intent-Driven Network" was its AI-based premium home broadband for a better user experience on Chinese based PON systems in use today.  Real time data collections allows 40% reduction on door-to-door service and fault prediction of 85% of Wi-Fi faults and 30% of all network faults.
6. AI-enabled, software-defined cameras are now available that perform low-light feature extraction (e.g. facial detection/comparison) over 85% of the time.  And, using the Huawei AI chip, it can outperform CPUs by 25X and GPUs by over 6x.
7. VR/AR will create a $2.7 trillion ecosystem in the future.  The company reminds the audience that it demonstrated teh first CloudVR Proof of Concept at the March 2018 MWC conference.

Q&A after keynote:
Mr. Eric Xu, Rotating Deputy Chairman of Huawei dodged several important questions relating to trade tariffs, cloud business unit revenue targets, growth rates of each major business units, specifics about AI full-stack claims made during the keynote, and instead focused generally on the AI theme.  Xu did, however, however, answer a handful of questions that were quite interesting:  Huawei won't acquire DRAM, Flash companies; and that 5G is not so revolutionary - it is just an evolution following LTE. Additionally, Xu mentioned that in 2H18, Huawei will launch end to end 5G solutions  and by 3Q19, it will launch 5G capable phones.  Xu said Huawei will continue to work with Intel on x86 for the foreseeable future.

More Q&A specifics:
Trade Tariffs and ZTE.  (In a moment of levity, however, Eric Xu smiled when the words ZTE were mentioned - recall that a day earlier, ZTE was penalized by the US).  We will focus on our customers and will ultimately survive. 

Cloud 1.5B by 2020, will you hit the target?  Will offer cloud services to telco service providers.  Huawei smartphones will leverage the Huawei cloud.  Enterprise customers will consume cloud services such as video, computing.  In future, trend will be enterprises will move to hybrid cloud and public cloud will take a major share.  Huawei cloud provides compute/storage/networking to enterprises and government.  200K x86 servers in Huawei cloud.  Revenue with external customers - won't share it with you - maybe .  

AI chipset question:  We don't position chipset as a standalone business - won't sell to external customers.  Will be used to differentiate Huawei products.  Smartphone - we use multi-vendor strategy always; in other worlds; have multiple Qualcomm, NTK and others.  Remain committed to multi-vendor strategy.  Don't want vendor lock-in, however.  If we only have one vendor, what might happen to our smartphone business, Xu asked.  

Enteprise business growth? Declined to comment on specifics, but said he encourages each to grow rapidly.  

How do customers get to 86% AI usage (the question was asked by an audience member by incorrectly referring to the statistic that was made during the keynote - specifically, Huawei said AI experimentation will be 86%, not AI usage)?  Will give clearer answer at Huawei Connect 2018.  For now, can share that we will use AI on ourselves first, then help customers on various functions such as finance, human resources, networks, etc.  

Supply chain - will you acqire your suppliers?  We do joint innovation with suppliers to meet Huawei's needs; push multi-source strategy, however.  Will not invest in DRAM, display, flash.

5G wasn't mentioned much in the presentation, why?  We don't have as high expectations as some others; 5G is just one of many products we offer and is just a natural evolution from 4G.  You don't have a fundamental difference between 4G and 5G - consumers just see faster speed and lower latency.  LTE already support autonomous driving.  Past couple years, governments have regarded 5G as too important.  June 2018, will only address eMBB - faster speeds.  2019 - will have fully 5G compliant system that does low latency.  4G is pretty robust; we don't see 5G as a national coverage network - it'll just focus on city centers.  However, once one carrier announces 5G, then all others must.  50% of Chinese have wireless connection capable of 4K but there are still no 4K stations.

2H18, end to end 5G solutions available.  3Q19, will launch 5G capable phones.

Share trends for Huawei at operators.  Revenue growth of telecom services is a challenging topic.  This revenue growth topic is why titan operators express concern about moving to 5G; instead, Huawei thinks moving to improved intelligence will assist operators.  Video will become more and more important as telcos become media companies too.  

Will AI become a privacy concern?  Any technology has double-sided effects.  With AI, some believe it can be dangerous.  Xu believes in the wisdom of man.  Look back to history of mankind, and our humanity can do same for mankind.

Will Huawei find alternate suppliers for data center products?  (Xu also smiled about this question before answering).  Today, Intel is dominant player.  Our point of view, we look forward to more diversified landscape; but we work with Intel mainly now.

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.

Nokia was bullish on its technology developments and cautious on telco capex.  CEO Rajeev Suri described the telecom market as having tough market conditions and expects telco equipment market revenues down in 2018.  He said the Swedish competitor pricing aggressively and that it will be difficult to keep share in China with 5G ramp.  He said Nokia is executing on plan to grow non telco verticals – and it will take 3+ years before it is sizable enough to potentially offset telco challenges.  He emphasized a key strength is its focus on cost reductions.  He highlighted success in cable MSO market and that its FP4-based router will ship in a few days.  Suri thinks 5G could roll out in China first, maybe tied with US.  Nokia CEO's comments were quite similar about 5G rollout timing expectations compared to comments made at Huawei’s recent conference (2019 initial deployments; chipsets 2019; broadening deployments in 2020).

Some more details from Rajeev Suri's presentation:
Ericsson.  We were surprised that the CEO of Nokia took the opportunity to take some digs at Ericsson.  He said that Ericsson is pricing aggressively; it also shared some quantitative statistics about competitive take-outs of Ericsson installed base. He argued that it has broadest portfolio in industry (fixed, software are examples).  

China.  Two interesting comments about China – a) will be difficult to maintain share in China as 5G rolls out, b) China might be first to deploy 5G.  
Emphasized that Amazon Web Services is making a presentation at this conference.  Said its new FP4-based routers are more efficient than any competitor and will be so for at least the next year.

Other presenters made comments about 5G mainly.  Here are some interesting comments:
Artificial Intelligence.  The company has a lot of network automation technology that is it working on but would not share details about this technology.  We guess Nokia is more open with its customers and that it'll make announcements at MWC '18 in Barcelona.
5G Radio.  Beamforming is a key technology that will be highlighted in 5G.  Also, the company's separation of Stage 1 and Stage 2 MIMO processing makes the bandwidth needs from baseband to array be much less than competitors.  Additionally, the company explains that its expected systems will have dramatically higher efficiency than competitors - again, the company kept its secrets here under wraps.  Late 2018 will see first 5G deployments, going into 2019.
IP/Optical.  Basil Alwan, President IP/Optical division said the first FP4-based product went to production end of the last week.  Major customers will take shipment before the end of this quarter.  The company will ship its 57 Terabit router during 1Q18.  SD-WAN will replace MPLS VPNs over time, perhaps at a rapid pace.  

Service Provider presentations:
Amazon Web Services IoT.  Satyam Yadav, GM of AWS IoT made a presentation at this meeting.  The presentation focused on how Amazon's IoT software and its services would be used in a partnership with Nokia to deliver Amazon IoT services.  
Sprint.  Ron Marquardt, CTO.  He is not sure how much customers might pay for lower-latency connections available from 5G.  Now that the uncertainty of the T-Mobile US acquisition is beyond us, Sprint says it is rapidly focusing on spending to upgrade its network.  Sprint also said it plans to deal with fewer vendors in the future.
Elisa. The Finnish operator presented data about its extraordinary data traffic growth and its per-subscriber data usage being far above competitors as well as other service providers in the world. 
​

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.

We attended the Nokia analyst meeting for its Fixed Access business, where the company explained its priorities for the upcoming year.  these include: (a) an expansion to its In-Home WiFi focus, (b) an aggressive push to move all but physical layer functions into the Cloud, and (c) the launch of fixed broadband wireless.  Last year's priorities included a push into the Cable broadband market (through the acquisition of Gainspeed) and Internet of Things (IoT).  The business leaders seem to be focused on what we'd consider to be the current trends in broadband, and Nokia is taking advantage of the competitive environment as the broadband market is consolidating around a shrinking number of players.

In-Home WiFi.  While some of the the company's Passive Optical Network (PON) Optical Network Terminals (ONTs) are currently shipping with Wi-Fi capabilities, it represents a growing trend among operators to offer a full function gateway.  The company plans to enhance its In-Home WiFi capabilities to entice its Service Provider customers to purchase these slightly more expensive devices.  The company ships something on the order of 3 million ONTs each quarter, generally on par with the number of in-home WiFi devices sold by one of the leaders of in-home WiFi, Netgear.  There has been a long-running trend whereby cable modems and DSL modems have incorporated WiFi, which has reduced the market opportunity for stand-alone WiFi routers, mainly in North America and European markets (where cable and DSL are popular).  However, where PON is popular, like in Asian countries (China included), PON modems have generally not incorporated WiFi until recently and WiFi capable ONTs represent a small fraction of all ONTs that ship.  Nokia plans to introduce a solution that extends and enhances WiFi beyond the gateway at some point - we've seen WiFi Extenders and now WiFi mesh experience significant growth in recent years.  What Nokia may be able to bring to the table, though, is WiFi extending products with deeper integration to the Service Provider operations.  This is a capability that will likely be embraced by operators in order to reduce the number of customer service calls to the operators themselves.  We have seen vendors like Arris make similar pronouncements of enhancing their WiFi strategies to include devices such as Extenders (but mainly for cable and DSL), so Nokia is not alone in being a broadband modem vendor recognizing the 'whole home' trend.  From a consumer WiFi perspective, Nokia's move to enhance its WiFi capabilities will put most pressure on standalone WiFi vendors that sell to Asian countries - these include D-Link, TP-Link, Buffalo, and Zyxel.

Broadband to the Cloud.  The Network Functions Virtualization (NFV) trend has now hit full steam, with nearly all mobile operator RFPs requiring vendors to offer software-based functions such as EPC, routing, IMS and other functions that can be run in so-called "Telco Clouds."  The broadband group at Nokia is expected over time to deliver on a portfolio that, where possible, will be running on these server-based environments.  We, similar to Nokia's expectation, expect that most fixed broadband "NFV" systems will be run in separate "clouds" from the mobile "clouds" for the next few years.  

Fixed Wireless.  We've all heard a lot about fixed wireless broadband trials at telcos in recent months.  Yesterday, for instance, AT&T announced an expansion of its trials.  Nokia will deliver on Fixed Wireless through its Fixed Broadband business group, an organizational acknowledgment that this is quite different from mobile wireless and will more likely be used to augment wired broadband strategies in difficult-to-reach locations.  Generally, Nokia's view is that fixed wireless is relatively more expensive than many wired broadband systems - we share this view.  It is hard not to be somewhat skeptical about fixed broadband wireless given the failed attempts to bring it to market going back as far as the early 1990's (AT&T's Project Angel), and then MMDS and LMDS efforts in the early 2000's, and of course WiMAX (more recently).  Nonetheless, Nokia is smartly positioning its plans to support fixed wireless as a way to augment wired broadband.  And, we know that fixed wireless works - Ubiquiti Networks has shipped tens of millions of fixed broadband wireless links to its customer base of Wireless Internet Service Providers (WISPs).

At the Ericsson Media and Analyst Briefing today, Ericsson's new CEO Borje Ekholm made his first MWC presentation, and then ceded the stage to well-known T-Mobile USA (TMUS) Chief Technology Officer, Neville Ray.  We learned several things that were interesting: T-Mobile's plans for 5G rollout and 2G/3G shutdown, and Ericsson's high-level view on its strengths as 5G rolls out.

Neville Ray's comments conveyed a pragmatic and agile service provider's views:

• 2/3rds of all voice minutes are now on Voice over LTE (VoLTE).  Ray challenged anyone in the audience to find another telecom service provider with a greater percentage of minutes on VoLTE.
• 93% of all wireless data is transmitted on LTE
• Plans to shut down 2G and/or 3G when 5G rolls out, elaborating that the company has decomissioned the 'lion's share' of 2G spectrum utilization.  However, Ray says it has found significant customer interest in its 2G (GSM) network for connecting to Internet of Things (IoT) devices fitted with GSM modules.  In fact, there is a debate at TMUS as to whether to shut down the 3G network before the 2G network.  TMUS claims it has taken share from AT&T because its competitor shut down its 2G network and IoT customers in the US market have signed up with TMUS.
• The company echoed views it has shared with the media in recent months - that it isn't so committed to virtualizing its network at this point.  The CTO explained that it has a sufficiently modern network core that it isn't necessary to upgrade to a Network Functions Virtualization (NFV) infrastructure - at least until it rolls out 5G - and he put the conversion-to-NFV timeframe at 3 to 4 years.
• TMUS is not thrilled with the prospects for 5G fixed wireless, the kind that replaces wired broadband.  He said that if this is all 5G does for the industry, we may as well all go home.
• The company has deployed only 1,000 small cells to date.  It plans as many as 5,000 to 6,000 by the end of 2017.  Part of this rollout is using unlicensed spectrum, and it will roll out LTE-U and LAA.

Ericsson CEO Borje Ekholm positioned Ericsson's view on 5G:

• 5G will be based on the cloud, and potentially we could see entire 5G networks running entirely on the cloud
• Ericsson is well positioned in 5G due to its exposure to virtualization, security and its strong position in OSS/BSS.
