AT&T Begins 5G Trial with Business Customer

December 8, 2016 — AT&T has launched the first U.S. 5G business customer trial, millimeter wave (mmWave) technology to power a 5G network experience in one of Intel’s Austin offices.

The carrier worked with Ericsson to conduct its first public 5G demo featuring streaming 4K HD video, real-time camera feeds and reaching speeds of nearly 14 gigabits per second. Now, it’s testing the 5G-related technology developed with Ericsson and Intel into the field.

During the trial, the carrier will test multiple enterprise proof of concept use cases, including internet access, VPN, Unified Communications applications and 4K video streams. The trial will showcase the potential of 5G VoIP over the 15 GHz and 28GHz spectrum bands.

Tom Keathley, senior vice president, wireless network architecture and design, AT&T, said, “This trial gives us an opportunity to test 4K HD video streaming across further physical distances between pieces of equipment. With our 5G and 4G LTE advancements, we expect speeds rivaling what we see from cable providers. Our path to 5G will help make this vision a reality faster.”


Huawei, Vodafone Achieve 20 Gbps Speeds in E-Band

July 26, 2016 — Huawei and Vodafone have completed a mmWave field test, covering single-user multiple input multiple output (SU-MIMO) with a strong reflection path to reach 20 Gbps UE peak rate, and multi-user multiple input multiple output (MU-MIMO) for long-range UE to reach 10 Gbps peak rate.

“It is the world’s first 5G outdoor field test at E-Band reaching 20 Gbps peak rate for a single user device with high spectrum efficiency. This peak user rate is targeted by ITU-R as a 5G requirement. This is a key milestone after the two companies signed a strategic MoU on 5G technologies last year and a 5G Acceleration MoU this July,” said Johan Wibergh, chief technology officer, Vodafone Group.

The demand for spectrum to provide higher-capacity mobile access and self-backhaul has been rising drastically due to soaring mobile broadband communications traffic, according Vodafone.

“As traditional lower bands used in current cellular access become ever more crowded, there is an increasing effort in the industry to explore the centimeter wave (cmWave) and millimeter wave (mmWave) bands to meet broadband speed requirements,” Eric Xu, rotating CEO of Huawei, said. “This test will contribute to the study of spectrum above 6 GHz for 5G enhanced mobile broadband, and to promote global spectrum harmonization in the coming World Radio Congress in 2019 (WRC-19).”

E-Band is millimeter wave (mmWave) band and can be used as a complementary spectrum band to the lower-band to deliver ultra-high mobile broadband speeds, which will enable applications such as VR/AR and will act as self-backhaul for the 5G mobile service traffic.

FiberTower Invests in PHAZR, Millimeter Wave Technology

June 22, 2016 — PHAZR and FiberTower have announced a partnership focused on developing high-speed 5G millimeter wave systems where FiberTower will participate in the initial round of funding along with iTimeFund and other investors. The PHAZR 5G-type systems will be capable of 16 gigabits per second per cell over FiberTower’s wide area licenses.

“The FiberTower investment will help PHAZR accelerate the deployment of its 5G technology for gigabit-per-second mobile and fixed access system utilizing mmWave bands between 24GHz and 39GHz,” said Pulin Patel, PHAZR board member from iTimeFund. In conjunction with its investment in PHAZR, FiberTower will also create the Technology Advisory Committee to its board of directors led by PHAZR CEO Farooq Khan.

“The ability to utilize FiberTower’s long-standing deployment capabilities and relationships across industry sectors, combined with FiberTower’s millimeter wave licenses, represents a unique and actionable opportunity to swiftly bring PHAZR’s solutions to the marketplace,” said Khan.

PHAZR’s millimeter wave system, which will be available in 2017, will be one of the industry’s first integrated, high-power, commercial, millimeter wave antenna array. At peak rates the system is expected to deliver 16 Gbps throughput per cell over a 200 MHz channel block, which will be an industry-first for these exclusively-licensed bands. Prototype equipment is expected to be available in 4Q 2016.
