Verizon completes its first 5G call

Verizon completed its first over-the-air call on a 3GPP-compliant 5G New Radio (NR) system using licensed millimeter wave spectrum.

The call, which was completed at Nokia’s facility in Murray Hill, New Jersey earlier this month, used Nokia's 5G CloudRAN solution, which is comprised of the Nokia AirScale baseband and radio, AirFrame server, and AirScale Cloud RAN running 5G NR 3GPP-compliant software. Qualcomm provided 5G NR prototype devices in smartphone form factors.

The companies described the test as an important milestone on the road to preparing Verizon’s network for widespread implementation of commercial 5G mobile services for consumers and enterprises.

“With this first 3GPP NR standards-based connection, Verizon continues to lead the development of 5G technology,” said Ed Chan, senior vice president and chief technology architect, Corporate Network & Technology, Verizon. “By partnering with Nokia and Qualcomm to combine 5G technology with our deep millimeter wave spectrum, we’re well on the way to being the first to usher in the next era of wireless communications for customers.”

“Nokia’s 3GPP-compliant high-capacity 5G solution supports pioneering operators like Verizon in leveraging their assets to make a true difference with 5G for their customers,” said Marc Rouanne, president of Mobile Networks, Nokia. “Using the successful interoperability testing we conducted with Qualcomm as a basis, we’re now applying our standard-compliant 5G technology in this trial with Verizon to push the commercialization of 5G.”

Verizon, Qualcomm and Novatel to expedite 5G NR mmWave rollout

Verizon, Qualcomm Technologies, and Novatel Wireless, are pushing ahead with plans to expedite the rollout of 5G New Radio (NR) millimeter wave (mmWave) technology.  The companies have agreed to collaborate on over-the-air field trials based on the 5G NR Release-15 specifications being developed by 3GPP, with hopes of moving the mobile ecosystem towards faster validation and commercialization of 5G NR mmWave technologies at scale before the end of the decade.

The expedited plan call for an initial focus on 5G NR operation in 28 GHz and 39 GHz mmWave spectrum bands. The goal is to achieve robust multi-gigabit per second data rates with mobility at significantly lower latencies than today’s networks. Over-the-air trials are expected starting in 2018, that will be compliant with the first 3GPP 5G NR specification that will be part of Release 15. The trials will utilize 5G NR mmWave mobile test platforms from Qualcomm and will employ advanced 5G NR Multiple-Input Multiple-Output (MIMO) antenna technology with adaptive beamforming and beam tracking techniques.


Qualcomm shows 5G NR mmWave prototype

Qualcomm unveiled a 5G NR mmWave prototype system based on the 5G New Radio (NR) Release-15 specifications.  Peak download speeds of up to 5 Gbps are possible.

The prototype system, which operates in millimeter wave (mmWave) spectrum bands above 24 GHz, demonstrates how advanced 5G NR mmWave technologies can be utilized to deliver robust mobile broadband communications at multi-gigabit-per-second data rates in real-world mobile environments.

Qualcomm's prototype leverages the company's optimized mmWave RF Front-end design in a smartphone form-factor to test and trial real-world mmWave challenges, such as device and hand-blocking. It employs Multiple-Input Multiple-Output (MIMO) antenna technology with adaptive analog beamforming and beam tracking/steering techniques, which is required for robust and sustained mobile broadband communications in non-line-of-sight (NLOS) environments and device mobility. It also supports 800 MHz bandwidth and advanced 5G NR technologies including LDPC channel coding for data channels.

NEC develops digital beamforming for 5G in 28GHZ band

NEC has successfully tested a new digital beamforming transmission method that uses a massive-element active antenna base station and 28 GHz band spectrum.

The demo is described as the simultaneous beamforming transmission (four multi-user MIMO) from a single massive-element active antenna system (AAS) to four terminals.  NEC achieved a 3.1 Gbps cell throughput by applying a frequency bandwidth of 300 MHz.
 
NEC said its massive-element AAS, supporting a 28 GHz band, adopts a fully digital control system, which improves the precision of beamforming. The fully digital control system enables simultaneous beamforming in multiple directions from a single massive-element AAS unit and efficiently implements high-speed and high-capacity communication without interfering with adjacent users through spatial multiplexing.

The beamforming takes into account multipath, a non-direct wave signal, and moderately adjusts beam directions as needed. It also cancels out interference through multipath and reduces performance deterioration caused by inter-cell interference.

NEC enables its advanced beamforming without digital/analog signal and frequency converters. Instead, the massive-element AAS adopts a fully digital control system with less power and more compact conversion functions.

"In order to effectively implement sophisticated services that apply 5G features from 2020 onward, it is essential to utilize 28 GHz and other high frequency radio bands, which enable the securing of wide bandwidth, and the utilization of beamforming," said Katsumi Tanoue, Deputy General Manager, Wireless Access Solution Division, NEC Corporation. "Moving forward, NEC will continue its efforts in development and demonstration tests for a massive-element active antenna base station system that delivers high speed, high capacity and massive connectivity."

Ericsson says 5G RAN software will be ready by Q4

Ericsson announced that its 5G Radio Access Network (RAN) software, based on the recently approved first 3GPP 5G New Radio (NR) standard, will be commercially available by Q4 2018, paving the way for operators to launch commercial services in 2019. The 5G radio network software complements Ericsson’s already launched baseband and 5G radios. The company says all of the base radios from the Ericsson Radio System delivered since 2015 will be 5G NR-capable by a remote software installation.

Ericsson’s 5G radio network software promises multi-band support for global deployment and will allow operators to use new frequency spectrum as it becomes available. It also introduces a new category of radio products called Street Macro – a new site type that addresses the need of operators to grow in cities with limited available radio locations. The idea is to place radios on building facades with a smaller footprint but the necessary strength to secure network efficiency and coverage. Ericsson is also adding new radios with Massive MIMO technology.

Ericsson also announced enhancements to its Distributed Cloud architecture, which support cloud application deployment across multiple sites - central, distributed, and edge. The design can be managed, orchestrated, and perceived as one solution in what the company calls "Software Defined Infrastructure (SDI) to the edge". In addition, the Ericsson Distributed Cloud will add support for hardware options in a multi-vendor framework.

Fredrik Jejdling, Executive Vice President and Head of Business Area Networks at Ericsson, says: “Operators who want to be early with 5G now have the essential pieces for launching 5G networks already this year. With our expanded platform, they will get more efficient networks as well as opportunities to create new revenues from emerging consumer and industrial use cases.”

Nokia's ReefShark silicon cuts massive MIMO antenna size and power consumption

Nokia unveiled its ReefShark 5G chipsets for radio frequency (RF) units such as the radio used in antennas. The chipsets, which were developed in-house, significantly improve radio performance resulting in halving the size of massive MIMO antennas. Nokia says its ReefShark chipsets also reduce power consumption in baseband units by 64%, compared to current technology.

The ReefShark chipsets comprise:

  • ReefShark Digital Front End for LTE and 5G radio systems supporting massive MIMO
  • ReefShark RFIC front-end module and transceiver: massive MIMO Adaptive Antenna solution
  • ReefShark Baseband Processor: All-in-one compute heavy design, capable of supporting the massive scale requirements of 5G. This is the brain power of baseband processing.

The ReefShark chipsets for compute capacity are delivered as plug-in units for the commercially available Nokia AirScale baseband module. The new plug-in units triple throughput from 28 Gbps today to up to 84 Gbps per module. Additionally, AirScale baseband module chaining supports base station throughputs of up to 6 terabits per second. Nokia said this level of performance will allow operators to meet the huge growing densification demands and support the massive enhanced mobile broadband needs of people and devices in megacities.

Nokia also announced that it is working with 30 operators using ReefShark and will ramp up field deployments during the third quarter of 2018.

Henri Tervonen, CTO of Nokia Mobile Networks and head of R&D Foundation said: "With ReefShark, Nokia has created a clear competitive advantage. Its combination of power, intelligence and efficiency make it ideally suited to be at the heart of fast arriving 5G networks."

Verizon and Ericsson hit 953 Mbps with 4-carrier aggregation

Verizon achieved a top downlink rate of 953 Mbps is a real-world LTE-Advanced field test in Florida conducted in partnership with Ericsson and Qualcomm. The test combined licensed and unlicensed bands with 4-carrier aggregation, 4x4 MIMO and 256 QAM. The new Moto Z2 Force and Samsung Note 8 are capable of performing at this level.

Verizon announced several other milestones at MWC-A:

  • LTE on CBRS: Verizon, Ericsson, Qualcomm and Federated Wireless will demonstrate the first use of CBRS band 48 spectrum for LTE with carrier aggregation using a true band 48 radio in the Ericsson Radio Dot System, Qualcomm MTP, Federated Wireless Spectrum Access System (SAS) and domain proxy in the Ericsson Network Manager. This group was the first to use this newly authorized spectrum an innovative spectrum sharing scheme, and will allow cellular systems to tap into 150 MHz of new spectrum in buildings and small cell clusters. The demonstration will showcase the possibility of both operator mobile broadband and private LTE use cases on the same radio.
  • 5G enhanced intelligent video surveillance: Today, 4G LTE is used to connect surveillance cameras across cities in the US. With 5G, there will be significantly more capacity to stream the captured video back to the network and support large numbers of cameras, enabling new levels of intelligence. With all streams coming to a central, video optimized repository in the core of the 5G network, additional analysis can be applied, providing actionable intelligence for end users. This 5G enhancement to an existing 4G solution will provide benefits across smart cities, marketing insights for retail, and security.
  • Drone powered by edge compute: The Verizon and Ericsson Distributed Edge Cloud amplifies the power of simple drones to match or exceed the capabilities of complex drones, which are much more expensive. This proof of concept demonstration shows that as intelligence and processing are moved to the 5G core and the very edge of the network, existing device constraints will be lifted, enabling advanced applications with low cost devices. This new kind of architecture will provide benefits to augmented and virtual reality use cases as well as industrial control and intelligent transport systems.

Nokia adds to AirScale Remote Radio Head portfolio

Nokia introduced new dual- and single-band FDD-LTE and TD-LTE radios as part or its AirScale Remote Radio Head portfolio. The new radios leverage carrier aggregation techniques, 4x4 MIMO and 8x4 Beamforming, while addressing demand for higher output power, extending frequency band support and simplifying network rollouts.

Nokia is also debuting its next wave of small cells with "Ultra Dense" self-organizing network features to simplify deployments. New capabilities solve issues caused by reducing the distance between new and existing small cells and ensure continuous optimization even as further densification occurs. Nokia has extended the self-organizing network features on its Femtocell portfolio to ensure smoother integration and higher performance in heterogeneous networks as traffic is offloaded from the macro network.

Nokia said its new Flexi Zone Citizen Band Radio Service small cells, supporting Spectrum Access Server and Citizen Broadband Radio Service Device Proxy connectivity, will offer operators new options for boosting coverage and capacity, particularly inside buildings. CBRS Flexi Zone small cells can be used to deploy neutral host capabilities, allowing operators to lease capacity to other providers inside malls, hotels and office blocks, where space is at a premium. In compliance with FCC requirements, small cells will be able to efficiently communicate with the Spectrum Access Server to ensure the network uses only available shared CBRS* spectrum.

Nokia Wavence microwave now supports Carrier SDN, which provides operators with intelligence and automation, including rapid power-up of virtual network functions and adaptable parameters to support changes on the radio access network, such as when people move from work to home.

In addition, Nokia continues to help operators plan and optimize their path to 5G using its 5G Acceleration Services and is now expanding the portfolio to include the operator 'anyhaul' end-to-end transport network. Nokia will work with operators to assess the readiness of the network and design and implement their 5G strategies and services.

Harold Graham, head of the 5G business line at Nokia, said: "Nokia is committed to providing the most effective and cost-efficient path to 5G for our customers through evolutionary enhancements to their networks. We truly understand how changes in each area of a network will affect the network as a whole, and as we evolve our end-to-end portfolio of technologies and services we are working closely with customers to ensure they are always ahead of their customers' needs and expectations."

New spectrum will shake up the mobile market

We will be hearing a lot about extending 4G LTE into new spectrum bands in the coming year even as 5G trials and pre-standard commercial deployments get underway in 2018.

Repurposing the 600 MHz band.

In August 2016, T-Mobile US lit up the first base stations using its newly acquired 600 MHz spectrum become the first mobile operator worldwide to activate commercial LTE service using this frequency band. A second 600 MHz location was activated in Scarborough, Maine about 2 weeks later and T-Mobile now says it is on track to light up 600 MHz cell sites in rural locations across the United States over the coming months.

T-Mobile’s 600 MHz rollout is interesting on a couple of fronts.  First, the pace of the rollout is impressive. The first activation, which occurred in Cheyenne, Wyoming, came only two months after T-Mobile received its spectrum licenses from the FCC.  Most of the spectrum licenses were previously held by broadcasters, such as public TV stations, or educational or religious entities which in the days before the commercial Internet really took off had once imagined a future where they would be broadcasting TV directly consumers in their local market. In rural areas, at least, it is proving easier to clear the spectrum for T-Mobile.

Second, T-Mobile now has plenty of 600 MHz licenses, which it acquired in the FCC’ Broadcast Incentive Auction in April for $7.99 billion, covering all of the U.S. and Puerto Rico. T-Mobile acquired 31 MHz of spectrum nationwide on average, quadrupling its low-band holdings, for a total of $7.99 billion. With the purchase, T-Mobile claims to hold more low-band spectrum per customer than any other major provider, and nearly 3x the low-band spectrum per customer held by Verizon, which did not bid in the auction to the surprise of many observers. Other companies picking up 600 MHz spectrum in that auction were Parker B Wireless (Dish Network) $6.2 billion; CC Wireless Investment (Comcast) $1.7 billion; AT&T $902 million; Channel 51 $859 million; Bluewater Wireless $568 million; US Cellular 329 million; NewLevel $296 million; Tsar 600 $131 million; and Omega Wireless $99.7 million.  There was a handful of other local or regional auction winner, implying that some deal-making is likely.

Third, 600 MHz will provide great building penetration and range. It also will be instrumental to T-Mobile’s 5G strategy. In addition to the 600 MHz bands, T-Mobile has 200 MHz of spectrum in the 28/39 GHz bands covering nearly 100 million people in major metros. The company says both resources will be used for 5G. In various company blog posts, T-Mobile argues that 5G should not be equated only with high-band, or millimeter wave, spectrum, even though these bands support massive throughput capacity. The limited range of the 28/39 GHz bands means that vast numbers of small cells will be required for ubiquitous coverage which will be a major capital expenditure.

Fourth, LV’s V30 announced at the end of August is the first smartphone to support 600 MHz LTE. Qualcomm has said that its Snapdragon X20 and X16 modems support 600 MHz. We don’t know yet whether the upcoming iPhones will support 600 MHz – it could be a game changer either way. If yes, it could be a home run for T-Mobile. If no, it could be a big strike-out.

GSA (the Global mobile Suppliers Association) recently reported that Argentina, Canada, Mexico and New Zealand are considering re-purposing and re-licensing 600 MHz spectrum in a similar fashion.

Refarming 450 MHz (Band 31)

Another area of activity around the world is 450 MHz, otherwise known as Band 31, which was widely used for CDMA networks. GSA tracks over 100 CDMA networks worldwide that relied on Band 31 for wide area reach and in-building penetration. The first carriers began deactivating CDMA 450 in 2014. Currently, GSA counts ten networks that have re-farmed this spectrum to extend their LTE coverage.
Ukko Mobile, Aland Islands (Baltic Sea)
Vimplecom (Beeline), Armenia
Net1, Denmark
Ukko, Finland
MVM, Hungary
Net1, Indonesia
Ice.net, Norway
Broadband Everywhere, Philippines
Tele2 (Skylink), Russia

3.5 GHz Mid-band spectrum for 5G
Lots of activity around 5G in the “mid-bands” of 3.5 GHz spectrum is underway in carrier test labs and with regulators, including the FCC. In April 2015, the U.S. Federal Communications Commission (FCC) adopted rules for CBRS, which opens 150 MHz of spectrum (3550-3700 MHz) for commercial use — while providing necessary protection of incumbent users of the band. Spectrum access is actively coordinated based on priority and granular location, making previously allocated spectrum available to new entrants and services. In 2016, the Citizens Broadband Radio Service (CBRS) Alliance was formed with the goal of making LTE-based solutions in the 3.5 GHz CBRS band widely available, Big name players are backing this initiative, including AT&T, American Tower, CableLabs, Intel, Nokia, ZTE, and others.

Another big milestone for 3.5 GHz spectrum came in late August, when Verizon, Ericsson, Qualcomm, and Federated Wireless demonstrated LTE Advanced carrier aggregation using CBRS band 48 spectrum. The demo, which was conducted in an Ericsson lab in Plano, Texas included the end-to-end CBRS communication flow, using 2x20 MHz LTE carriers on the CBRS band 48, and employing a 256 QAM modulation in the downlink. Ericsson provided the band 48 Radio Dot System and Domain Proxy for communication with Federated SAS. Qualcomm Technologies provided a Qualcomm Snapdragon LTE modem test device, and Federated Wireless provided the spectrum management service with their Spectrum Controller.

A month earlier, in July 2017, ZTE and China Unicom announced a field test in Shenzhen that achieved data rates of up to 2 Gbit/s using the 3.5 GHz frequency band with a 100 MHz bandwidth. This test was conducted by ZTE working with the Guangdong branch of China Unicom and the operator's network construction department and the China Unicom Network Technology Research Institute. The field test was designed to verify the 5G technical performance and product commercial capabilities in a live network environment and builds on the established partnership for 5G network development between China Unicom and ZTE.

 Licensed Assisted Access (LAA) looks ready to go

After several years of incubation, Licensed Assisted Access (LAA) appears to be on the cusp of commercial rollout. The magic with LAA is that it enables operators to use unlicensed spectrum in combination with licensed bands. It co-exists with Wi-Fi and other unlicensed spectrum technologies using 'listen before talk', which promises fair coexistence, Multiple carriers are the world are now trialling LTE-LAA or beginning commercial rollouts, boasting of downlink speeds nearing the gigabit mark. In June, AT&T and Ericsson conducted a live LTE-LAA technology field trial, during which initial wireless data rates of more than 650 Mbps were achieved in downtown San Francisco. Also in June, T-Mobile completed the nation’s first mobile broadband data session live in the field using License Assisted Access (LAA) on its commercial network. Italian operator TIM has achieved speeds of nearly 1Gbps on its live advanced 4G network in Milan using Ericsson’s LAA technology.  In addition, Ericsson, Verizon and Qualcomm have reported downlink performance of 953 Mbps in a joint commercial network deployment in Boca Raton, Florida.

DT activates its first pre-standard 5G connection in Berlin

Deutsche Telekom activated its first, pre-standard 5G connection over its commercial network in central Berlin using 3.7 GHz spectrum.

The 5G connection is operating a over 2 Gbps with a low latency of three milliseconds.

Huawei supplied the user equipment based on 3GPP specifications for 5G New Radio (NR), the deployment on commercial sites is the first in Europe and marks an important advancement in the global development of 5G.  

DT said the implementation in a live real-world setting in central Berlin using Huawei equipment and software is based on pre-standard 5G that closely tracks the 3GPP global standard for so-called ‘Non-Standalone New Radio’. With the Non-Standalone 5G NR mode for the enhanced Mobile Broadband (eMBB) use-case, it is meant that the connection is anchored in LTE while 5G NR carriers are used to boost data-rates and reduce latency. Therefore, 5G new radio will be deployed with the evolution of 4G LTE as the baseline for wide-area broadband coverage. The specifications enabling that system will be complete by December 2017 as part of the first drop of 3GPP Release 15.

“5G new radio will be critical for meeting our customers’ ever-increasing connectivity requirements that are steadily growing with more and more network connections,” said Claudia Nemat, Deutsche Telekom Board member for Technology and Innovation. “Our achievement demonstrates the feasibility of our plans to deliver a superior, new customer experience.”

“As long time partners, both Deutsche Telekom Group and Huawei have joined hands to successfully test 5G NR equipments in field environments based on latest 3GPP R15 standards. These achievements highlight the capabilities of the 5G NR equipment to meet operators’ requirements for addressing new business opportunities for end users. Huawei is confident that the partnership with Deutsche Telekom can fully prepare the commercial launch of 5G NR services in Europe by 2020 thanks to 3GPP standardization efforts,” said Huimin Zhu, Vice President 5G Huawei.

AT&T partners with Ericsson for 5G trial of DIRECTV NOW in Austin

AT&T, which last year completed what it claimed to be the first fixed wireless 5G business customer trial in Austin, has announced the launch of a second trial involving the use of millimetre wave (mmWave) technology to deliver high speed 5G network services to more locations in Austin, Texas.

AT&T's second trial is designed to provide an ultra-fast Internet connection to residential, small business and enterprise locations utilising Ericsson's 5G RAN and the Intel 5G Mobile Trial Platform. Trial participants will be able to stream premium live TV via DIRECTV NOW and access faster broadband services over a fixed wireless 5G connection.

AT&T believes that the trial will provide speeds of up to 1 Gbit/s using mmWave spectrum. It noted that earlier this year it successfully delivered DIRECTV NOW utilising mmWave technology at its Middletown lab in New Jersey, which was claimed to be the first time DIRECTV NOW had been delivered over a 5G connection.

The latest trial covers a variety of customers, such as residential, small business and enterprise, and by using DIRECTV NOW and other applications AT&T is seeking to gain further insights into mmWave performance characteristics and better understand the need for standards development.

The fixed wireless 5G trial in Austin is due to last for several months. AT&T will also continue 5G testing using its network testbeds. At the same time, the company will continue its research into the role of software-defined networks and experimenting with advanced virtualised-RAN core network capabilities during the year.


The operator stated that data traffic on its mobile network has increased by more than 250,000% since 2007, with video now constituting more than half of mobile data traffic. In addition, video traffic has risen by over 75% and smartphones were responsible for nearly 75% of data traffic carried in 2016.

Ericsson: over half a billion 5G users in five years

A big question that must weigh on the minds of the directors at Ericsson is how soon 5G rollouts will begin. It has been a tough few years at Ericsson in particular, and for many other non-Chinese network equipment vendors in the mobile space as well. Many of the big mobile operators in the developed markets have already completed their 4G LTE network construction. Minor upgrades and fill-in projects continue, but for the most part the big spending campaigns have slowed to a trickle.  With mobile penetration rates exceeding 100% in many markets, the networks can only grow by poaching subscribers from local rivals. The good news is that traffic-per-user is surging and the networks gradually are filling up. On the horizon are many innovative apps that promise even heavier network loads, and when standards are fully-baked and new spectrum licenses secured, a healthy upgrade cycle to 5G should begin. In the meantime, there are LTE-A enhancements underway and Gigabit LTE deployments in progress. The big question for Ericsson is: when will 5G begin and how fast will the network upgrades occur?

The latest edition of the Ericsson Mobility Report has just been released. The company has updated this report on an annual or semi-annual basis for the past five years, providing its mobile operator customers and the market at-large with valuable predictions concerning technology and usage trends.

5G is perhaps the starring topic again in this edition of the Mobility Report, with the big finding that by 2022 Ericsson predicts there will be more than half a billion 5G subscriptions, with a population coverage of 15%.

This figure is bolder than what Ericsson has published before. For instance, in June 2014, Ericsson was still expecting a slower uptake for LTE to persist, particularly in Europe. In that forecast from 3 years ago, Ericsson predicted that by the end of 2019, LTE would make up around 50% of the subscriptions base in Western Europe. Of course, in 2014 not everyone had to carry a smartphone. In fact, only 65% of all phones sold in Q1 2014 were smartphones. The 3G network in Europe was well developed, so the Ericsson Mobility Report expected these trends to linger. The current report finds that GSM/EDGE still constitutes the largest category of mobile subscriptions, but that LTE will become the dominant mobile access technology in 2018, and will likely reach 5 billion subscriptions by the end of 2022, or more than seven times the GSM/EDGE-only subscriptions. This will be the final sunset for 3G.

In this year's report, Ericsson calculates that the total traffic in mobile networks increased by 70% between the end of Q1 2016 and the end of Q1 2017 - a huge leap! Incidentally, a big part of the gain is linked to Reliance Jio Infocomm launching its LTE network in India and offering free mobile data on a trial basis. Within six months of launch, Jio reached 100 million broadband and VoLTE customers, making it the fastest growing operator in the world for 2016. But traffic is surging for many other reasons as well.

5G New Radio specs will incentivise early rollouts

Earlier planning anticipated the 5G upgrade cycle to begin in the new decade, sometime after the 2020 Tokyo Olympic Games. At this year’s Mobile World Congress in February, major mobile network operators and vendors issued a call to accelerate the 5G New Radio (NR) standardisation schedule to enable large-scale trials and deployments as early as 2019, a year earlier than the previous expected timeline. In March 2017, 3GPP complied with this request by approving the acceleration of the 5G NR standardisation schedule to include an intermediate milestone for an early variant called Non-Standalone 5G NR.

Key findings

To follow are some interesting highlights on network evolution from Ericsson Mobility Report:

Ericsson anticipates that by the end of 2022 there will be 9 billion mobile subscriptions. Mobile broadband subscriptions will reach 8.3 billion, thereby accounting for more than 90% of all mobile subscriptions. The number of unique mobile subscribers is estimated to reach 6.2 billion by the end of 2022.

There are more than 1 million new mobile broadband subscribers every day.

LTE subscriptions reached a total of 2.1 billion in Q1 2017, up by 250 million new subscriptions during the quarter.

Operators are evolving their existing LTE networks to LTE-Advanced (LTE-A) networks with Category1, 4, 6, 9, 11 and 16 implementations, combining lower and higher frequency bands (both for FDD and TDD modes).

There are currently 591 commercial LTE networks deployed in 189 countries. Out of these, 194 have been upgraded to LTE-A networks.

Ericsson anticipates that the number of VoLTE subscriptions will reach 4.6 billion by the end of 2022, making up more than 90% of all LTE subscriptions globally.

The upgrade to LTE occurred significantly faster than the upgrade from 2G to 3G. In just 5 years, LTE was adopted by 2.5 billion users; it took eight years for 3G to reach this milestone.

Ericsson now expects some large-scale trials early commercial deployment of 5G in 2019 that will use the 5G NR specs.

The adoption rate of 5G mobile broadband is expected to be similar to that of LTE, with rollouts commencing in major metro areas.

Ericsson now expects North America to take a leading role in 5G rollouts as the major U.S. operators have each stated their intention to expand into pre-standard 5G. By 2022, Ericsson predicts that 25% of North American subscribers could be on 5G.

The first commercial use of 5G is expected to be for enhanced mobile broadband and fixed wireless access (FWA).

5G radio access lowers round trip latency to under 4 ms, as seen in a 5G test bed conducted by Scania and Ericsson in Sweden.

Attributes of 5G, including network slicing and low latency, will make safe public transport using autonomous vehicles a reality.

Huawei and TELUS Collaborate on 5G

Huawei and telco TELUS of Canada announced they have successfully completed a 5G wireless connection using the global 3GPP technology standards platform as the industry moves towards the deployment of 5G.

TELUS noted that the pilot not only demonstrates the faster wireless speeds and lower latency that will be available to customers using 5G technology, but also showcases the potential for 5G technology to deliver wireless-to-the-premise (WTTx) connectivity with speeds and reliability required for smart homes and businesses.

The pilot network created with Huawei was designed to reflect a real-world point-to-multi-point connection over commercial central office equipment and transport networks. The network featured equipment based on 3GPP 5G foundational technologies over 28 GHz spectrum, although 5G standards are not expected to be finalised until early in 2018.
The pilot forms part of TELUS and Huawei’s joint 5G Living Lab facility in Vancouver, where the companies have been trialling next-generation technologies since 2015 in a live real-world environment. TELUS noted that last year the Living Lab demonstrated speeds of 30 Gbit/s in a controlled environment and implemented a heterogeneous network (HetNet) in downtown Vancouver.

While 5G wireless technology is expected to become commercially available in 2020, TELUS stated that customers living in the Vancouver area will have early access to the latest wireless technologies leveraging advances achieved at the 5G Living Lab.



  • Previously, in October last year TELUS and Huawei announced they had achieved wireless speeds of up to 29.3 Gbit/s at the 5G Living Lab in Vancouver. The companies also equipped a 4G LTE wireless site in Vancouver with the latest LTE-Advanced Pro technologies, enabling speeds of up to 1 Gbit/s, and planned to upgrade a further 5 sites.

ZTE completes 26 GHz field testing in Beijing

ZTE claims that it has become the first vendor to conduct 26 GHz high-frequency field tests during the second phase of China's 5G test in Huairou, Beijing.

ZTE stated that it led the 26 GHz high-frequency field testing of its 5G new radio (NR) pre-commercial base station, which was demonstrated to deliver strong performance in interconnecting with the instruments and chips from a number of manufacturers. In addition, ZTE has applied to conduct official tests using frequency bands greater than 40 GHz in its Shanghai R&D centre as part of its efforts to develop solutions for the high frequency bands.

ZTE noted that the 5G testing is led by China, and organised and implemented by the IMT-2020 (5G) Promotion Group, which includes the China Academy of Information and Communications Technology (CAICT), China Mobile, China Telecom, China Unicom and DOCOMO of Japan.

The latest 5G test program in China is covers technical solution verification as part of the second phase of testing and focuses on verifying technical solutions in the areas of continuous wide coverage, high capacity (low and high frequency), low latency and high reliability, low power consumption and hybrid scenarios.

ZTE added that China started to build the 5G test program earlier this year, which is believed to be the largest such test initiative, as well as the most advanced, and is based on an open test platform. Through the program, China is aiming to integrate core strengths in the industry and to promote global 5G standardisation and technology development.

Following the completion of the first phase of China's 5G technology R&D test, ZTE noted that it is engaged in the second-phase testing. Using its latest IT baseband unit (BBU), 5G multi-band active antenna unit (AAU) and NR air interface technologies, ZTE has launched field tests designed to address key performance requirements in typical application scenarios such as enhanced spectral efficiency, greater connection density, higher reliability and lower delay air interfaces.

Nokia demos AirScale to support 5G

Nokia announced that testing has highlighted the flexibility, upgradeability and scalability of its AirScale radio portfolio to adapt to support the frequency bands that will be used for the initial applications of 5G technology.

By demonstrating the ability of the AirScale platform to support both low and high bands, Nokia stated that operators will be able to provide both wide area and indoor coverage for early 5G operations without the need to carry out complicated network reconfigurations.

Nokia noted that 5G promises to change connectivity by delivering lower latency, increased spectral efficiency and improved energy efficiency, while the range of applications enabled by 5G, such as improved connectivity in dense urban environments to Industry 4.0 applications and fixed wireless access, will require the use of high-band frequencies (millimetre and centimetre wave) as well as the evolution of existing low-band frequencies.

At the 5G World Summit in London, UK, Nokia will showcase how AirScale, a core component of its 5G FIRST solution, can leverage its Flexi RF units that are already deployed by operators to enable the continued use of existing radio technology as they prepare to transition networks to 5G. During the event Nokia will also outline the use of different spectrum bands, ranging  from sub-1 GHz to millimetre wave, to meet expectations in terms of depth of coverage and higher capacity and data rates promised by 5G.

Nokia explained that 5G applications, such as connecting IoT devices, coverage for indoor environments and over large areas, necessitate the use of low-band frequencies. The company noted that the ability to utilise these bands has recently been verified in tests at its 5G labs in Finland, including the 700 MHz, 800 MHz and 850 MHz frequencies.



  • Nokia showcased its 5G FIRST end-to-end solution incorporating AirScale and AirFrame technology at the Mobile World Congress in February. The 5G FIRST solution specifically features Nokia's AirScale massive MIMO adaptive antenna for 3.5 GHz, 4.5 GHz, 28 GHz and 39 GHz frequency bands, cloud packet core and shared data layer and mobile transport elements. The solution is scheduled to launch in the second half of 2017.
