The company is asking for Special Temporary Authority to advance its understanding of 5G and network potential in the millimeter wave bands
STAMFORD, Conn. — Charter Communications is going ahead with more tests of fixed wireless in the 28 GHz band, in and around the Los Angeles area. The cable company is asking the FCC for Special Temporary Authority to advance its understanding of 5G technology and network potential in the millimeter wave bands, according to fiercewireless.com . The application lists Ericsson as the manufacturer of 25 units to be tested.
The company is asking for the STA for 180 days, starting at the end of March. The goal of the tests is to develop techniques and to gain a greater understanding of fixed wireless broadband systems in the millimeter-wave bands.
Charter is also seeking permission to conduct more tests to study coverage, capacity and propagation in the 3550-3700 MHz CBRS band. Their latest application calls for outdoor fixed wireless experiments in Lexington, Kentucky, using 19 different models of equipment, according to the same article. “Charter plans to continue testing in rural communities to investigate further how to expand the speeds and services it delivers,” the company said.
Charter has also shown its support to the FCC for the opening of the 5.9 GHz band for unlicensed use as soon as possible, noting the 5.9 GHz band’s size, location and capacity would be ideal for “next-gen” technologies.
Last summer, California capital fast-tracked Verizon’s request for access to city utility poles for small cells and city conduit for fiber backhaul
SACRAMENTO, Calif. — Sacramento residents will be Verizon’s potential 5G customers this year when the company launches residential broadband service based on its own version of 5G. Verizon will offer 5G customer premise equipment that it says will deliver wireless internet and video at speeds comparable to fiber speeds, according to rcrwireless.com .
California’s capital last summer fast-tracked Verizon’s request for access to city utility poles for small cells and city conduit for fiber backhaul—they got access to 101 utility poles and several miles of conduit. In return, Verizon is placing Wi-Fi hotspots in 27 Sacramento parks.
XO Communications previously owned the millimeter-wave spectrum licenses in Sacramento now owned by Verizon. The company picked a handful of the cities formerly served by XO to be 5G trial cities, but Sacramento is the only city named so far, according to the same article.
City officials gave up potential lease payments for pole space in exchange for the high-speed wireless service Verizon is offering, and the city’s CIO believes the deal with Verizon will bring more technology startups to Sacramento. The city retained the right to lease space on its utility poles to other carriers in the future.
At some point in the future Sacramento and other Verizon 5G trial cities will need to upgrade in order to use the same 5G equipment used elsewhere in the company’s network. The gear deployed in Sacramento will use 5G radio heads and CPEs made by Samsung, using Verizon’s proprietary 5G standard. Verizon said it expects the transition to standards-compliant 5G will only require a software or firmware upgrade to the radios and the customer premise equipment.
5G trial is being promoted by the Italian government
MATERA, Italy—Italian mobile operator TIM, Italian broadband provider Fastweb and manufacturer Huawei have announced the activation of the first 5G antenna system in the city of Matera as part of a 5G trial being promoted by the Italian government, reports rcrwireless.com .
The Italian cities of Bari and Matera will be among the first areas in the world to be covered by the new generation of mobile technology. Use of 3.7-3.8 GHz frequency bands, made available by the Ministry of Economic Development, will facilitate project’s network development plan. 75 percent coverage of the two cities’ is planned for by the end of this year.
Huawei recently announced the completion of the first 5G trial in the city of Turin, Italy, also in partnership with TIM and Fastweb. A net throughput of more than 3 Gbps has been achieved using 100 megahertz of spectrum, according to Huawei. The 5G trial also reached a spectral efficiency of 30 bits/second/hertz, which is about seven times higher than advanced 4G technology, according to the same article.
Vodafone is also engaged in 5G trials in Italy. In December last year, the telco launched its project to test 5G technologies via the 3.6-3.8 GHz band in the city of Milan. The company said the network will cover 80 percent of the city and surrounding metropolitan areas by the end of next year and 100 percent by 2019. Download speeds of 2.7 Gbps and a latency of just over a millisecond were reported in the first live end-to-end 5G data connection in Italy.
Customers in Chicago, Dallas and Los Angeles will begin experiencing “5G-like” capabilities, as Sprint rolls out Massive MIMO
OVERLAND PARK, Kan. — In April, Sprint customers in select U.S. markets will experience “the future of wireless” as the company prepares its first 5G mobile network in the first half of 2019.
Customers in Chicago, Dallas and Los Angeles will begin experiencing “5G-like” capabilities, including significant increases in data speed and capacity, as Sprint rolls out advanced network technology called Massive MIMO, according to this press release from Sprint. The company will aggressively expand to additional markets including Atlanta, Houston and Washington later this year.
Sprint’s first 5G-ready Massive MIMO cell sites are capable of delivering up to 10 times the capacity of current LTE systems. All Sprint customers using a 2.5 GHz (band 41) device will benefit from the increased capacity and speed provided by Massive MIMO. Sprint is working with Qualcomm and device manufacturers to launch 5G mobile devices in the first half of 2019. The recently announced Qualcomm Snapdragon X50 5G modem supports 5G NR for Sprint’s 2.5 GHz (n41) spectrum band.
Sprint will deploy 64T64R (64 transmit, 64 receive) Massive MIMO radios using 128 antennas working with technology leaders Ericsson, Nokia, and Samsung Electronics. The Massive MIMO radios from all three suppliers are software-upgradable to 5G without additional tower climbs. The Massive MIMO radios support split-mode service, enabling Sprint to offer both 4G LTE and 5G on the same radio.
In 2018 and 2019 Sprint expects to deploy thousands of Massive MIMO radios, significantly increasing network capacity for millions of customers across the country, according to the same press release.
T-Mobile plans to have its 5G network built-out in 30 cities by the end of 2018. The first four of those were recently announced — New York, Los Angeles, Dallas, and Las Vegas, according to theverge.com .
Unfortunately, no one will actually be able to use the 5G network this year, though. T-Mobile CTO Neville Ray said it wouldn’t be until this time next year that the first phones that could use the network will become available. When the time does come what can consumers expect? Speeds should be faster, but T-Mobile (and other carriers) are talking about 5G as an extension of LTE, rather than a replacement for it.
“5G is another incremental step, and it will become a much larger one as time moves forward,” Ray said, quoted in the same article.
T-Mobile plans to use millimeter wave spectrum and more traditional LTE-range wireless bands to build its 5G network, which should provide enhanced speeds and broad reach.

Verizon will deploy 5G first in US
PYEONGCHANG, South Korea — Intel, Korea Telecom and Toyota decided last June to install a commercial 5G test network in Korea for the Winter Olympics in PyeongChang, which drew to a close Sunday. The companies said the system — made up of 22 5G links spanning 10 different sites — delivered 3,800 terabytes of data during the two-week event.
The companies involved in the test effort built four main use cases to show off the technology, including a system that used hundreds of cameras to capture ice-skating athletes, footage that was then broadcast in real time to virtual reality viewers, according to fiercewireless.com . Viewers “could use the setup to select different locations from which to view the action and could also pause and replay specific parts of the performance.” Other test cases used connected Toyota automobiles and transmitted high-resolution pictures of cross-country skiers
KT said that the test paves the way for the launch of commercial 5G services, based on the 3GPP’s recently ratified 5G standard, in the country by the first quarter of next year, according to the same article.
Here in the US, Verizon says it will be the first to deploy fixed and mobile 5G. “We’re going to be first and we’re committed to being first,” Chris Schmidt, executive director of device technology at Verizon Communications told lightreading on Monday at this year’s Mobile Wireless Conference in Barcelona. Like KT, Verizon will be using the initial 3rd Generation Partnership Project (3GPP) 5G New Radio (NR) specification. Verizon will be moving to mobile “as soon as possible,” Schmidt said, but exactly when will depend on the device makers, according to the same article. Several chipmakers have said that they will deliver a 5G modems in 2018.
Will explore 3450-3550 MHz band’s suitability for commercial wireless services
WASHINGTON — “We are fully committed to collaborating with NTIA to ensure that the U.S. continues to lead the world in advanced wireless technologies as we chart the course to our 5G future,” FCC Chairman Ajit Pai said in a statement Monday.
Pai was reacting to the announcement that the U.S. Department of Commerce’s National Telecommunications and Information Administration’s has selected the 3450-3550 MHz band for a feasibility study exploring the band’s potential for commercial wireless services; this spectrum is currently used for federal purposes, according to Pai’s statement.

“The commission, working together with NTIA, has already made the 3.5 GHz band available for wireless services and we recently initiated a process to consider whether all or parts of the adjacent satellite spectrum can also be made available. Altogether, this could unleash a contiguous block of hundreds of megahertz of valuable spectrum for new technologies and services, including 5G,” Pai said.
Atlanta, Dallas and Waco, Texas, will be among a dozen cities where the carrier will deploy 5G by the end of 2018
NEW YORK — AT&T said Atlanta, Dallas and Waco, Texas, will be among a dozen cities where the carrier will deploy 5G-based mobile services by the end of 2018.
AT&T plans to identify the other deployment markets in the coming months.
AT&T reiterated that its mobile 5G deployment will be based on emerging 3GPP standards, holding that the offering will integrate with current LTE technologies using the non-standalone configuration outlined in 3GPP release 15. AT&T claims that the equipment being rolled out to its LTE network will enable a migration to 5G.
Additionally, AT&T’s mobile 5G rollout will operate over millimeter wave spectrum in some areas (it began to conduct 5G trials with millimeter wave spectrum in mid-2106), but also expects to provide mobile 5G using additional spectrum bands.
Given the limitations of millimeter wave spectrum (it needs almost perfect line-of-site and is susceptible to blockage from trees, foliage and buildings, for example) some mobile and wireless experts believe that 5G will need to run on a “dual-PHY” network that employs a fallback to sub-6 GHz spectrum.
Early on, as AT&T awaits handsets that support 5G to emerge, it will initially deploy 5G-based mobile services using a small router-like device that can connect other devices to the 5G network.
“Think of it as a puck,” Randall Stephenson, AT&T’s chairman, president and CEO, said on the company’s Q4 call in late January. “The thing [that’s] going to cause 5G to go slow, more than anything else – it’s just avaialbity of handsets,” he said, adding that AT&T will be “pushing the vendors” to accelerate their work with 5G-ready handsets.
AT&T plans to add more 5G- capable mobile devices and smartphones by “early 2019.”
AT&T is also moving ahead with a software defined network deployment that, it says, will go “hand in hand” with 5G. AT&T said it hit its goal to have 55% of its network virtualized by end of 2017 and that the current plan is virtualize 75% by 2020.
AT&T said it will launch mobile 5G in 12 U.S. markets this year
NEW YORK — AT&T said it will launch mobile 5G in 12 U.S. markets this year, without revealing which markets they will be. It has dropped a hint by publicly praising three U.S. cities that have paved the way for small cells, according to rcrwireless.com .
Small cell deployments, critical to 5G, often require access to the public rights of way; city governments will thus be very involved in the development of 5G wireless networks. Carriers often target city-owned assets for the installation of sites, and may need to trench city streets to lay fiber for front-haul and/or backhaul. Indianapolis, Minneapolis and Little Rock were singled out by AT&T.
More than 80 small cells for AT&T are on-air in Indianapolis thanks to a streamlined permitting process and a maximum attachment rate of just $50 per node. AT&T has named Indianapolis as one of its 5G Evolution test markets. Minneapolis is also a 5G Evolution test market, and AT&T has plans to install about 115 small cell nodes there.
Minnesota and Indiana are among a handful of states that have adopted small cell legislation. Florida, Colorado, Arizona, Kansas, and Virgina have also passed laws to facilitate small cell deployments. Arkansas has not yet passed a state law regarding small cells, but Little Rock has set the maximum small cell permitting time at 60 days. The company plans to deploy more than 100 nodes in the city this year, according to the article.
