Ericsson Forecast: 1 Billion Global 5G Subscriptions in 2023

Global 5G subscriptions will reach 1 billion by the end of 2023, with 5G covering more than 20% of the global population, Ericsson has predicted.

Ericsson’s latest Mobility Report predicts that the first 5G new radio deployments will go live in 2019, with major deployments from 2020. Early 5G deployments are expects in markets including South Korea, Japan, China and the US.

LTE will meanwhile become the dominant mobile access technology by the end of this year. But after reaching a peak in 2021, subscriptions are expected to drop off slightly as they are supplanted by 5G.

Global LTE subscribers are tipped to reach an estimated 5.5 billion subscriptions by the end of 2023, with a global LTE population coverage of 85%.

VoLTE subscriptions are also expected to reach 5.5 billion by end-2023, accounting for more than 80% of combined LTE and 5G subscriptions.

The report also projects that global mobile data traffic will pass 100 exabytes per month in 2023, the equivalent of 5.5 million years of HD video streaming.

Mobile-subscriptions-by-technology

  • 5G will cover more than 20 percent of the global population six years from now, according to the latest Ericsson Mobility Report
  • Mobile data traffic continues to grow, primarily fueled by increased viewing of video content
  • LTE will be the dominant access technology by end of this year, driven by demand for improved user experience and faster networks

“The latest report highlights trends in mobile subscription and data traffic growth, as well as the industry’s effort to tackle the increasing demands on mobile networks globally,” Ericsson chief strategy officer and head of technology and emerging business Niklas Heuveldop said.

“In addition, the report examines the emergence of new use cases as network capabilities evolve – smartwatches, IoT alarms, and augmented reality-assisted maintenance and repair, to name a few. As we prepare for 5G, these trends will continue to set the agenda for the mobile industry going forward.”

LG U+ & Huawei complete 5G network test in Seoul, South Korea

South Korea telco LG U+ and its wireless network equipment partner Huawei confirmed that they have completed what they say is the world’s first large-scale 5G network test in a pre-commercial environment. The test network was situated in the Gangnam District of Seoul, South Korea and consisted of both 3.5GHz and 28GHz base stations (the two most popular frequency bands for 5G globally so far).

The partners said the test also helped to successfully verify the technologies of UHD (4K) IPTV video and other commercial 5G services in a typical dense, urban environment. High-speed mobility, dual connectivity, and inter-cell handovers under continuous networking conditions were also validated.

LG U+ reported that the test results for the end-to-end network trial returned average data rates of 1Gbit/s over the 3.5GHz frequency band and more than 5Gbit/s for dual connectivity over both high and low bands.

During the trial in a typical dense urban area, the companies achieved average data rates of 1Gbps over the low band and more than 5Gbps for dual connectivity under both low and high bands.  A peak data rate of 20Gbps was attained through this dual connectivity.

“The world’s first large-scale joint 5G pre-commercial test indicated a significant breakthrough in 5G,” said Kim Dae Hee, VP of the 5G Strategy Unit at LG U+. “We believe that Huawei is set to help LG U+ implement the world’s first Commercial 5G network over 3.5GHz”

LG U+ took to the road with its 5G Tour Bus to showcase 4K IPTV (picture below). It also demonstrated a VR drone designed by Huawei’s Wireless X Labs and kitted out with what the vendor says is the world’s first 5G customer premise equipment (CPE) operating in the 3.5GHz band. The demonstration reportedly showed throughput speeds of up to 1.5Gbit/s whilst the drone was flying at an altitude of over 100m.

“In the Gangnam District of Korea, we have successfully validated the 5G pre-commercial network and released the world’s first 3.5GHz CPE.,” said Zhou Yuefeng, CMO of Huawei’s Wireless Product Line.

“This demonstrates that Huawei will maintain its capability to provide competitive E2E 5G network products in 2018. LG U+ and Huawei will continue to conduct further research into 5G technologies and build a robust E2E industry ecosystem to achieve business success in the upcoming 5G era.”

The test results returned average data rates of 1 Gbps over the low band and more than 5 Gbps for dual connectivity over high and low bands. A peak data rate of 20 Gbps and an average data rate of more than 5 Gbps were achieved through dual connectivity over 3.5 GHz and 28 GHz. During the test, a 5G tour bus delivered 5G-based IPTV 4K, and a VR drone was demonstrated in the ‘5G for All’ experience room at the LG U+ headquarters, which required data rates ranging from 20 Mbps to 100 Mbps.

Editor’s Notes:

  1. South Korea’s mobile network operators are expected to roll out trial 5G services in time for the 2018 Winter Olympics. SK Telecom (SKT) completed a successful test of five-band carrier aggregation (5C). SK Telecom, KT and LG U+‘ launched the world’s first commercial interconnected VoLTE service.
  2. South Korea’s mobile market has slow growth over the last few years due to a highly mature market. Organic growth by the three main mobile operators, together with the multitude of niche MVNOs will result in further growth to 2018 however growth rates will taper off further over the next few years as the market further matures. Market penetration reached 117% in 2016 and is predicted to reach between 119% and 122% by 2021 driven by the uptake of both 4G and 5G services. The split in mobile operator market share has remained relatively constant over the last two decades. LG U+ (formerly known as LG Telecom) has made a marginal increase in market share over that time.

New ITU-T Standards for IMT 2020 (5G) + 3GPP Core Network Systems Architecture

New ITU-T standards related to “5G”:

ITU-T has reached first-stage approval (‘consent’ level) of three new international standards defining the requirements for IMT-2020 (“5G”) network systems as they relate to network operation, softwarization and fixed-mobile convergence.

The standards were developed by ITU-T’s standardization expert group for future networks, ITU-T Study Group 13.

Note: The first-stage approvals come in parallel with ITU-T Study Group 13’s establishment of a new ITU Focus Group to study machine learning in 5G systems.

End-to-end flexibility will be one of the defining features of 5G networks. This flexibility will result in large part from the introduction of network softwarization, the ability to create highly specialized network slices using advanced Software-Defined Networking (SDN), Network Function Virtualization (NFV) and cloud computing capabilities.

The three new ITU-T standards are the following:

  • ITU Y.3101 “Requirements of the IMT-2020 network” describes the features of 5G networks necessary to ensure efficient 5G deployment and high network flexibility.
  • ITU Y.3150 “High-level technical characteristics of network softwarization for IMT-2020” describes the value of slicing in both horizontal and vertical, application-specific environments.
  • ITU Y.3130 “Requirements of IMT-2020 fixed-mobile convergence” calls for unified user identity, unified charging, service continuity, guaranteed support for high quality of service, control plane convergence and smart management of user data.

ITU’s work on “International Mobile Telecommunications for 2020 and beyond (IMT-2020)” defines the framework and overall objectives of the 5G standardization process as well as the roadmap to guide this process to its conclusion by 2020.

ITU’s Radiocommunication Sector (ITU-R) is coordinating the international standardization and identification of spectrum for 5G mobile development. ITU’s Telecommunications Standardization Sector (ITU-T) is playing a similar convening role for the technologies and architectures of the wireline elements of 5G systems.

ITU standardization work on the wireline elements of 5G systems continues to accelerate.

ITU-T Study Group 15 (Transport, access and home networks) is developing a technical report on 5G requirements associated with backbone optical transport networks. ITU-T Study Group 11 (Protocols and test specifications) is studying the 5G control plane, relevant protocols and related testing methodologies. ITU-T Study Group 5 (Environment and circular economy) has assigned priority to its emerging study of the environmental requirements of 5G systems.

ITU-T Study Group 13 (Future networks), ITU’s lead group for 5G wireline studies, continues to support the shift to software-driven network management and orchestration. The group is progressing draft 5G standards addressing subjects including network architectures, network capability exposure, network slicing, network orchestration, network management-control, and frameworks to ensure high quality of service.

“5G” Core Network functions & Services Based Architecture:

The primary focus of  ITU-R WP5D IMT 2020 standardization efforts are on the radio aspects (as per its charter).  That includes the Radio Access Network (RAN)/Radio Interface Technology (RIT), spectral efficiency, latency, frequencies, etc.

To actually deliver services over a 5G RAN, a system architecture and core network are required. The core network provides functions such as authentication, session management, mobility management, forwarding of user data, and (possibly) virtualization of network functions.

3GPP Technical Specification (TS) 23.501 — “System Architecture for the 5G System” — is more commonly referred to as the Service-Based Architecture (SBA) for the 5G Core network.  It uses service-based interfaces between control-plane functions, while user-plane functions connect over point-to-point links. This is shown in the figure below. The service-based interfaces will use HTTP 2.0 over TCP in the initial release, with QUIC transport being considered for later 3GPP releases.

………………………………………………………………………………………….
Various aspects of this new core network design are described in a new Heavy Reading white paper — Service-Based Architecture for 5G Core Networks.

There are many aspects to this, but the white paper highlights:

  • How the idea of “network function services” (3GPP terminology) aligns with the micro-services based view of network service composition
  • How operators may take advantage of decoupled control- and user-plane to scale performance
  • How the design might enable operators to deploy 5GC functions at edge locations, such as central offices, stadiums or enterprise campuses

The first 5G core standards (really specifications because 3GPP is not a formal standards body) are scheduled to be included in 3GPP Release 15, which “freezes” in June next year and will be formally approved three months later. This will be a critical release for the industry that will set the development path of the 5G system architecture for years to come.

Editor’s Note:

From http://www.3gpp.org/specifications:

“The 3GPP Technical Specifications and Technical Reports have, in themselves, no legal standing. They only become “official” (standards) when transposed into corresponding publications of the Partner Organizations (or the national / regional standards body acting as publisher for the Partner).”

AT&T Deploys LTE Licensed Assisted Access (LTE-LAA) Technology; Plans 5G Evolution

AT&T has introduced a high speed “4G” service in the form of LTE-Licensed Assisted Access (LAA) in Indianapolis, IN.  LTE-LAA uses unlicensed spectrum. According to AT&T it will provide theoretical gigabit speeds to some areas of the city.  LTE-LAA has reached a peak of 979 Mbps in a San Francisco, CA trial.

“Demand continues to grow at a rapid pace on our network,” the Bill Soards, President AT&T Indiana in a press release. That’s why offering customers the latest technologies and increased wireless capacity by combining licensed and unlicensed spectrum is an important milestone.”

The U.S. mega telco recently announced plans to roll out its 5G Evolution program in Minneapolis.  That initiative – which aims to provide networks with the capability to support 5G when it is ready – already is in use in parts of Indianapolis and in Austin, TX. It features LTE Advanced features such as 256 QAM, 4×4 MIMO and 3-way Carrier Aggregation.

AT&T says that it invested $350 million in its wired and wireless network infrastructure in Indianapolis between 2014 and 2016.

Highlights of 2017 Telecom Infrastructure Project (TIP) Summit

Executive Summary:

The Telecom Infra Project (TIP) is gaining a lot of awareness and market traction, judging by last week’s very well attended TIP Summit at the Santa Clara Convention Center.  The number of telecom network operators presented was very impressive, especially considering that none were from the U.S. with the exception of AT&T, which presented on behalf of the Open Compute Project (OCP) Networking Group.   It was announced at the summit that the OCP Networking group had formed an alliance with TIP.

The network operators that presented or were panelists included representatives from:  Deutsche Telekom AG, Telefonica, BT, MTN Group (Africa),  Bharti Airtel LTD (India), Reliance Jio (India), Vodafone, Turkcell (Turkey), Orange, SK Telecom, TIM Brasil, etc.  Telecom Italia, NTT, and others were present too.   Cable Labs – the R&D arm of the MSOs/cablecos – was represented in a panel where they announced a new TIP Community Lab (details below).

Facebook co-founded TIP along with Intel, Nokia, Deutsche Telekom, and SK Telecom at the 2016 Mobile World Congress event.  Like the OCP (also started by Facebook), its mission is to dis-aggregate network hardware into modules and define open source software building blocks. As its name implies, TIP’s focus is telecom infrastructure specific in its work to develop and deploy new networking technologies. TIP members include more than 500 companies, including telcos, Internet companies, vendors, consulting firms and system integrators.  Membership seems to have grown exponentially in the last year.

During his opening keynote speech, Axel Clauberg, VP of technology and innovation at Deutsche Telekom and chairman of the TIP Board of Directors, announced that three more operators had joined the TIP Board: BT, Telefonica, and Vodafone.

“TIP is truly operator-focused,” Clauberg said. “It’s called Telecom Infrastructure Project, and I really count on the operators to continue contributing to TIP and to take us to new heights.” That includes testing and deploying the new software and hardware contributed to TIP, he added.

“My big goal for next year is to get into the deployment stage,” Clauberg said. “We are working on deployable technology. [In 2018] I want to be measured on whether we are successfully entering that stage.”

Jay Parikh, head of engineering and infrastructure at Facebook, echoed that TIP’s end goal is deployments, whether it is developing new technologies, or supporting the ecosystem that will allow them to scale.

“It is still very early. Those of you who have been in the telco industry for a long time know that it does not move lightning fast. But we’re going to try and change that,” Parikh said.

…………………………………………………………………………………………………………………….

TIP divides its work into three areas — access, backhaul, and core & management — and each of the project groups falls under one of those three areas.  Several new project groups were announced at the summit:

  • Artificial Intelligence and applied Machine Learning (AI/ML): will focus on using machine learning and automation to help carriers keep pace with the growth in network size, traffic volume, and service complexity. It will also work to accelerate deployment of new over-the-top services, autonomous vehicles, drones, and augmented reality/virtual reality.
  • End-to-End Network Slicing (E2E-NS): aims to create multiple networks that share the same physical infrastructure. That would allow operators to dedicate a portion of their network to a certain functionality and should make it easier for them to deploy 5G-enabled applications.
  • openRAN: will develop RAN technologies based on General Purpose Processing Platforms (GPPP) and disaggregated software.

The other projects/working groups are the following:

  • Edge Computing: This group is addressing system integration requirements with innovative, cost-effective and efficient end-to-end solutions that serve rural and urban regions in optimal and profitable ways.
  •  This group is pioneering a 60GHz wireless networking system to deliver gigabits of capacity in dense, urban environments more quickly, easily and at a lower cost than deploying fiber.  A contribution was made to IEEE 802.11ay task force this year on use cases for mmW backhaul.

  • Open Optical Packet Transport:  This project group will define Dense Wavelength Division Multiplexing (DWDM) open packet transport architecture that triggers new innovation and avoids implementation lock-ins. Open DWDM systems include open line system & control, transponder & network management and packet-switch and router technologies.
  • The Working Group is focused on enabling carriers to more efficiently deliver new services and applications by using mobile edge computing (MEC) to turn the RAN network edge (mobile, fixed, licensed and unlicensed spectrum) into an open media and service hub.
  • The project is pioneering a virtualized RAN (VRAN) solution comprised of low-cost remote radio units that can be managed and dynamically reconfigured by a centralized infrastructure over non-ideal transport.
  • project group will develop an open RAN architecture by defining open interfaces between internal components and focusing on the lab activity with various companies for multi-vendor interoperability. The goal is to broaden the mobile ecosystem of related technology companies to drive a faster pace of innovation.

A complete description, with pointers/hyperlinks to respective project/work group charters is in the TIP Company Member Application here.

TEACs –  Innovation Centers for TIP:

Also of note was the announcement of several new TEACs – TIP Ecosystem Acceleration Centers, where start-ups and investors can work together with incumbent network operators to progress their respective agendas for telecom infrastructure.

The TIP website comments on the mission of the TEACs:

“By bringing together the key actors – established operators, cutting-edge startups, and global & local investors – TEACs establish the necessary foundation to foster collaboration, accelerate trials, and bring deployable infrastructure solutions to the telecom industry.”

TEACs are located in London (BT), Paris (Orange), and Seoul (SK Telecom). .

TIP Community Labs:

TIP Community Labs are physical spaces that enable collaboration between member companies in a TIP project group to develop telecom infrastructure solutions. While the labs are dedicated to TIP projects and host TIP project teams, the space and basic equipment are sponsored by individual TIP member companies hosting the space.  The labs are located in: Seoul, South Korea (sponsored by SK Telecom); Bonn, Germany (sponsored by Deutsche Telekom); Menlo Park, California, USA (sponsored by Facebook). Coming Soon Rio de Janiero, Brazil – to be sponsored by TIM Brasil.  At this summit, Cable Labs announced it will soon open a TIP Community Lab in Louisville, CO.

Selected Quotes:

AT&T’s Tom Anschutz (a very respected colleague) said during his November 9th – 1pm keynote presentation:

“Network functions need to be disaggregated and ‘cloudified.’  We need to decompose monolithic, vertically integrated systems into building blocks; create abstraction layers that hide complexity.  Design code and hardware as independent modules that don’t bring down the entire IT system/telecom network if they fail.”

Other noteworthy quotes:

“We’re going to build these use-case demonstrations,” said Mansoor Hanif, director of converged networks and innovation at BT. “If you’re going to do something as difficult and complex as network slicing, you might as well do it right.”

“This is the opening of a system that runs radio as a software on top of general purpose processes and interworks with independent radio,” said Santiago Tenorio, head of networks at Vodafone Group. The project will work to reduce the costs associated with building mobile networks and make it easier for smaller vendors to enter the market.  “By opening the system will we get a lower cost base? Definitely yes,” absolutely yes,” Tenorio added.

“Opening up closed, black-box systems enables innovation at every level, so that customers can meet the challenges facing their networks faster and more efficiently,” said Josh Leslie, CEO of Cumulus Networks. “We’re excited to work with the TIP community to bring open systems to networks beyond the data center.” [See reference press release from Cumulus below].

“Open approaches are key to achieving TIP’s mission of disaggregating the traditional network deployment approach,” said Hans-Juergen Schmidtke, Co-Chair of the TIP Open Optical Packet Transport project group. “Our collaboration with Cumulus Networks to enable Cumulus Linux on Voyager (open packet DWDM architecture framework and white box transponder design) is an important contribution that will help accelerate the ecosystem’s adoption of Voyager.”

Closing Comments:  Request for Reader Inputs!

  1.  What’s really interesting is that there are no U.S. telco members of TIP.  Bell Canada is the only North American telecom carrier among its 500 members. Equinix and Cable Labs are the only quasi- network operator members in the U.S.
  2. Rather than write a voluminous report which few would read, we invite readers to contact the author or post a comment on areas of interest after reviewing the 2017 TIPS Summit agenda.

AT&Ts Perspective on Edge Computing from Fog World Congress

Introduction:

In her October 31st keynote at the Fog World Congress, Alicia Abella, PhD and Vice President – Advanced Technology Realization at AT&T, discussed the implications of edge computing (EC) for network service providers, emphasizing that it will make the business case for 5G realizable when low latency is essential for real time applications (see illustration below).

The important trends and key drivers for edge computing were described along with AT&T’s perspective of its “open network” edge computing architecture emphasizing open source software modules.

Author’s Note:  Ms. Abella did not distinguish between edge and fog computing nor did she even mention the latter term during her talk.  We tried to address definitions and fog network architecture in this post.  An earlier blog post quoted AT&T as being “all in” for edge computing to address low latency next generation applications.

………………………………………………………………………………………………………………..

AT&T Presentation Highlights:

  • Ms. Abella defined EC as the placement of processing and storage resources at the perimeter of a service provider’s network in order to deliver low latency applications to customers.  That’s consistent with the accepted definition.

“Edge compute is the next step in getting more out of our network, and we are busy putting together an edge computing (network) architecture,” she said.

  • “5G-like” applications will be the anchor tenant for network provider’s EC strategy.  augmented reality/virtual reality, Multi-person real time video conferencing, and autonomous vehicles were a few applications cited in the illustration below:

Above illustration courtesy of AT&T.

“Size, location, configuration of EC resources will vary, depending on capacity demand and use cases,”  said Ms. Abella.

…………………………………………………………………………………………………………..

  • Benefits of EC to network service providers include:
  1. Reduce backhaul traffic
  2. Maintain quality of experience for customers
  3. Reduce cost by decomposing and disaggregating access function
  4. Optimize current central office infrastructure
  5. Improve reliability of the network by distributing content between the edge and centralized data centers
  6. Deliver innovative services not possible without edge compute, e.g. Industrial IoT autonomous vehicles, smart cities, etc

“In order to achieve some of the latency requirements of these [5G applications?] services a service provider needs to place IT resources at the edge of the network. Especially, when looking at autonomous vehicles where you have mission critical safety requirements. When we think about the edge, we’re looking at being able to serve these low latency requirements for those [real time] applications.”

  • AT&T has “opened our network” to enable new services and reduce operational costs.  The key attributes are the following:
  1. Modular architecture
  2. Robust network APIs
  3. Policy management
  4. Shared infrastructure for simplification and scaling
  5. Network Automation platform achieved using INDIGO on top of ONAP
  • AT&T will offer increased network value and adaptability as traffic volumes change:
  1. Cost/performance leadership
  2. Improved speed to innovation
  3. Industry leading security, performance, reliability

“We are busy thinking about and putting together what that edge compute architecture would look like. It’s being driven by the need for low latency.”

In terms of where, physically, edge computing and storage is located:

“It depends on the use case. We have to be flexible when defining this edge compute architecture. There’s a lot of variables and a lot of constraints. We’re actually looking at optimization methods.  We want to deploy edge compute nodes in mobile data centers, in buildings, at customers’ locations and in our central offices. Where it will be depends on where there is demand, where we have spectrum, we are developing methods for optimizing the locations.  We want to be able to place those nodes in a place that will minimize cost to us (AT&T), while maintaining quality of experience. Size, location and configuration is going to depend on capacity demand and the use cases,” Alicia said.

  • Optimization of EC processing to meet latency constraints may require GPUs and FPGAs in additional to conventional microprocessors.  One such application cite was running video analytics for surveillance cameras.
  • Real time control of autonomous vehicles would require a significant investment in roadside IT infrastructure but have an uncertain return-on-investment. AT&T now has 12 million smart cars on its network, a number growing by a million per quarter.
  • We need to support different connectivity to the core network and use “SDN” within the site.
  • Device empowerment at the edge must consider that while mobile devices (e.g. smart phones and tablets) are capable of executing complex tasks, they have been held back by battery life and low power requirements.
  • Device complexity means higher cost to manufacturers and consumers.
  • Future of EC may include “crowd sourcing computing power in your pocket.”  The concept here is to distribute the computation needed over many people’s mobile devices and compensate them via Bitcoin, other crypto currency or asset class.  Block chain may play a role here.

Australia’s ACMA Targets 3.6-GHz for “5G” Mobile Broadband

Australian telecoms regulator ACMA has announced plans to reallocate spectrum in the 3.6-GHz band for 5G purposes.

The five-year spectrum outlook released today by ACMA details how Australia’s telecom regulator will adjust spectrum usage of 50MHz of the 900MHz band for 4G mobile broadband, switching from the roughly 8MHz paired chunks of spectrum that worked best with 2G to sets of matched 5MHz pairs more efficient for 4G networks. This won’t happen until mid-2021 to give telcos enough time to roll out appropriate hardware, and also takes into account the as-yet-unallocated 850MHz ‘expansion’ band, where two 15MHz portions sit unused.

However, it’s 3.6GHz that’s most interesting, because that massive 125MHz portion of spectrum could be huge for 5G mobile connectivity or even fixed wireless broadband across Australia. 3.6GHz is “being looked at internationally as a pioneer band for 5G mobile broadband”, according to ACMA chair Nerida O’Loughlin, and ACMA wants Australia to be positioned well to take advantage of any early developments. Telstra sits on the 5G steering council, and both Vodafone and Optus have already done significant testing with network partners.

The Australia telecom regulator also plans to re-allocate the 2G spectrum being freed by the switch off of 2G services for more modern mobile services.  In order to achieve these goals the regulator is following a new five-year spectrum roadmap, which was published last week.

The outlook includes details of planned spectrum allocations including possible auction scenarios, as well as a proposed approach to the development of annual spectrum work programs.

‘The 3.6 GHz band is being looked at internationally as a pioneer band for 5G mobile broadband. We want to make sure Australia is well placed to realize the benefits 5G has to offer,” ACMA chairwoman Nerida O’Loughlin said.

‘Now that 2G services have been or are being switched off, the ACMA is also keen to re-farm the 900 MHz GSM band and optimise its utility for newer generation mobile broadband services, such as 4G. We propose to do this over a number of years to avoid disruption of existing services. We also plan to make available additional spectrum already planned for reallocation to mobile broadband in the 850-MHz band.”

Verizon, Ericsson Team Up for Massive MIMO Deployment

Verizon and Ericsson have deployed frequency division duplexing (FDD) Massive Multiple Input-Multiple Output (MIMO) technology on the Verizon’s wireless network in Irvine, Calif., a step forward in implementing “5G” wireless communications. Ericsson provided 16 transceiver radios and 96 antenna elements in an array for the deployment.

The two companies say the Massive MIMO deployment will improve spectral and energy efficiency, increasing network capacity for current devices in the market.  Other network enhancements are expected to provide higher and more consistent speeds for using apps and uploading and downloading files, clearing the pathway for “5G” deployment.

The massive MIMO deployment is running on a 20 MHz block of AWS spectrum.  Four-way transmit has been widely deployed throughout the Verizon network and has contributed to significant 4G LTE advancements, according to the announcement. The high number of transmitters from the Massive MIMO provides more possible signal paths.  It also enables beamforming, which directs the beam from the cell site directly to where the customer is, dramatically cutting down on interference.  Reduced interference results in higher and more consistent speeds for customers.

Note:  Massive MIMO is a candidate feature for IMT 2020 (standardized 5G).  Please see last references for authoritative status of IMT 2020.

……………………………………………………………………………………………………….

“While continuing to drive 5G development, the deployment of Massive MIMO offers very tangible benefits for our customers today.  As we innovate, we learn and continue to lay the groundwork and set the standards for 5G technology,” said Nicola Palmer, Verizon Wireless chief network officer, in a prepared statement. “Our collaboration with Ericsson on this new deployment continues to drive industry-wide innovation and advancements.”

“We have a tremendous excitement around 5G, and today we made a great announcement to our commitment of driving the 5G ecosystem,” Verizon SVP Atish Gude said

Niklas Heuveldop, Ericsson head of market area North America said: “Massive MIMO is a key technology enabler for 5G, but already today, 4G LTE service providers and end users can benefit from the superior capacity and network performance this technology enables.  The current trial is an important step in the collaboration we have with Verizon to prepare their network for 5G.”

Ericsson is active with massive MIMO deployments on other carrier networks, including Sprint, who announced a deployment last month.

Ericsson Survey: Network Operators Focus on New Markets for 5G Revenue

Survey Highlights:

Most network operators say they’re ready for “5G” even if they don’t know what it will actually deliver (the RAN and other key functions haven’t even been discussed by ITU-R WP5D for IMT 2020, let alone agreed upon), Ericsson found in a survey of wireless network operators around the world (see References and hyper-links below). Many expect the enterprise market and Internet of Things (IoT) applications to drive revenue growth from 5G technology.

More than three-quarters of the respondents said they were in the midst of 5G trials.  That corresponds with research from the Global Mobile Suppliers Association research which found 81 5G trials underway in 42 countries.

23% of survey respondents plan to migrate 4G subscribers to 5G with enhanced services and revenues (but when?).  Yet nearly two thirds (64%) of operators said they can’t pay for 5G by simply raising rates on consumers, because consumers are “tapped out.”  Eighteen percent of respondents said they expect to monetize 5G by “expanding to new markets—enterprise/ industry segments.”

“In 2016, 90% pointed to consumers as the central segment in their planning and only 34% focused on specialized industries,” the Ericsson researchers wrote in this year’s report.  An increased emphasis on the enterprise market is a key shift since a previous Ericsson 5G operator survey was conducted in 2016.

“This year, operators are seeing that the consumer market is saturated, so planning for 5G is more evenly split across specialized industry segments (58%), business users (56%) and consumers (52%),” the Ericsson researchers added.

Specific industry segments on which operators expect to focus 5G monetization efforts include media/entertainment (cited by 69% of respondents), automotive (59%), public transport (31%), healthcare (29%) and energy/ utilities (29%).

Providing industry-specific services to these industry segments will be important in 5G monetization, according to 68% of respondents. The single most important use case in the media/entertainment segment is high-quality streaming, respondents said. Other top use cases by segment included:

  • Automotive: autonomous vehicle control
  • Public transport: Smart GPS
  • Healthcare: Remote robotic surgery
  • Energy & utilities: Control of edge-of-grid generation

More than three quarters (77%) of respondents said third-party collaboration is an essential element in 5G monetization and 68% said they need to find new revenue-sharing models.

Survey Questions and Methodology:

Some of the questions asked in the survey:

-Exactly how have preparations for 5G evolved over the past year?
-Where do telcos stand now in their 5G activities and developments?
-What actions are service providers taking now in anticipation of 5G?
-What priorities drive their initiative?
-How ready are they to take leadership positions in the 5G future?

The survey’s objective was to obtain a snapshot of the state of the industry in relation to next-generation mobile technology. Last year, we struggled to find 50 executives globally who were far enough along in 5G to answer the survey questions.

This year, Ericsson says they “easily identified 50 executives, both business and technical leaders, from 37 operators around the world. As leaders of their organizations’ 5G efforts, they are at the center of the 5G evolution. That increase clearly signifies the growing recognition among industry leaders of 5G’s importance.”s
