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.
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
Japan’s SoftBank plans to work with Ericsson to conduct a joint trial of “5G” in the 4.5-GHz band in dense urban areas of Japan. The end-to-end trial will involve two 5G new radios, a virtual RAN and EPC, beamforming, Massive multiple input multiple output (MIMO) functionality and test support services.
The trial is set to commence once Softbank obtains an experimental 5G license, Ericsson said.
Editors Note: Of course, no one knows what the “5G” air interface/RAN will be for this trial, because it’s not even been considered by ITU-R WP 5D which is standardizing IMT 2020. That 5G standardization work is scheduled to be completed by the end of 2020.
The key question is where will the “5G” endpoints/handsets come from? Ericsson doesn’t make ’em any more! Neither does Nokia which is involved in several other “5G” trials. Huawei and ZTE “5G” trials are in better shape, because both vendors make handsets/smartphones as well as base stations.
3GPP Progress on 5G can be found in this presentation. It’s crucial to note that 3GPP Release 15 (to be completed March 2018) will aim at a first phase of expected “5G” deployments in 2020 and is dependent on LTE. 3GPP Release 16 (true 5G) will target a submission to the ITU WP5D IMT-2020 standards committee.
In March 2017, SoftBank was granted an experimental licence to conduct tests in the 28GHz millimeter wave band and teamed up with Ericsson for trials that were to be conducted in indoor and outdoor environments covering both mobile and stationary tests. That followed more basic tests in the 4.5-GHz and 15-GHz bands in Tokyo in 2016.
The operator also recently announced plans to deploy Ericsson’s Radio Dot system across Japan to improve indoor coverage in high-density urban areas. Softbank has been testing the technology since 2015.
SoftBank announced in June it was working with ZTE to run trials on the 4.5GHz band in areas of metropolitan Tokyo.
SoftBank also is planning tests on the 4GHz and 15GHz bands and began conducting pre-standard 5G field trials with Ericsson in August 2016. It deployed Massive MIMO on its 4G network in the second half of 2016.
The wireless network operator, with a 19 per cent market share in Japan, aims to be one of the first in the world to launch commercial 5G services in 2020 or soon thereafter. SoftBank wants to be one of the first global network operators to deploy 5G services once the standardization process is complete and seeks to position itself as a pioneer of 5G.
According to the Financial Times (on line subscription required):
Telecom Italia plans to test its home grown “5G” technology in the micro-state of San Marino next year, making it the first country in the world to boast a nationwide 5G network. The state of San Marino, which has little more than 30,000 citizens, extends to only 61 sq km, making it the smallest republic in the world.
Telecom Italia Mobile (TIM) has signed a memorandum of understanding with the government of the tiny country to upgrade the existing 4G-LTE network in advance of a trial of “5G” services in 2018. It will double the number of mobile sites and will install a network of small cells in downtown San Marino, a Unesco heritage site, this year that will provide the backbone of the future commercial network. Investment in 5G network trials are taking place around the world with carriers in South Korea, China and the US among the most active in testing 5G technology. Giovanni Ferigo, head of technology for Telecom Italia Mobile, said San Marino’s 5G network would be the first in Europe “for sure.”
It was not revealed who created the specs for the Italian telco’s “5G” network or where Telecom Italia will procure the end point devices/handsets. One would assume that Ericsson is supplying TIM with the “5G” base stations, based on a MOU signed between the two companies in March of this year. TIM wrote in a press release on March 2, 2017:
TIM and Ericsson are committing to share skills, projects, laboratories and resources for designing, testing and building the technological components of the new 5G network needed to create a complete and open ecosystem around next-generation digital services.
In particular, the agreement will directly involve the research and innovation structures of the two companies, focusing on the design and testing of access infrastructure, the respective antenna systems and network virtualisation solutions, particularly through joint participation in Italian and European research projects and integration of service platforms for testing in the field of innovative Use Cases.
The 5G system will provide peak speeds of up to dozens of Gbps for UltraHD services and cloud computing solutions, a decrease in communication latency, reducing it to a few milliseconds, reliability for mission-critical services and service density with the ability to connect up to a hundred thousand terminals per cell. These characteristics mean that 5G will become the reference mobile network for next-generation digital services (such as virtual reality) and for the industrial Internet (robotics, manufacturing, health, environment, self-driving logistics).
The agreement is part of the “5G for Italy” initiative launched in 2016 by TIM and Ericsson for the establishment of an ecosystem of experimental industrial partners, confirming the commitment of the two companies to innovating technologies and networks in support of the socio-economic growth of the country.
Telecom Italia is also testing “5G” in Milano and Torino, but has more freedom in San Marino to experiment because of fewer restrictions on the use of airwaves than in Italy.
“We need to experiment as soon as possible,” Mr Ferigo said. The work done in San Marino would play a critical role in the future of 5G technology in Italy but was also crucial to the wider European sector as standards for the new network are refined.
“For 5G, our intention is a European leadership in standardization,” he said. The European Commission published a 5G action plan last year when it estimated that sectors such as healthcare, transport, cars and utilities would see economic benefits of €113bn by 2025 from the technology. However, the European Commission does not generate any telecom standards. For Europe, that’s ETSI which contributes to 3GPP and its members contribute to ITU-R WP 5D which is standardizing true 5G (as we’ve noted in numerous blog posts/articles).
Earlier this year, Telecom Italia Mobile (TIM) said LTE customers are expected to account for around 90% of its mobile broadband customers by 2019; That’s due to almost blanket LTE coverage of Italy with network speeds up to 75 Mbps and peaks of 500 Mbps in the main cities via the use of LTE Advanced Carrier Aggregation.
The above referenced FT “5G” article states:
Some countries have committed to the first 5G launches in 2019 but the wider telecoms industry is still struggling to define exactly what 5G technology is and some have argued that it is not yet clear how they can justify spending billions on the new network.
Mr Ferigo said the San Marino launch would be “very important” in defining the use case for 5G that would transform all sectors from healthcare to robotics to public transport. Telecom Italia has started working with companies including Maserati and Ducati on the use of better wireless technology but also the makers of parmesan cheese who want to better monitor the cows in their fields. Small territories have been used in the past for telecoms testing. The first 3G trial in the UK took place on the Isle of Man, while the remote Isle of Bute in Scotland was used to test “white space” technology.
