SoftBank, Ericsson Set to Experiment with 5G at 28 GHz

March 26, 2017 —

SoftBank has been granted an experimental license to conduct tests on the 28 GHz frequency band, and will commence indoor and outdoor trials in Tokyo Waterfront City, using Ericsson’s 28 GHz 5G test bed, which supports advanced features of the next generation technology.

The coming trial will cover both device mobility and stationary tests and include base stations and device prototypes with control signal feedback using mid-band spectrum at 4.5 GHz. Advanced 5G technologies will include massive-MIMO, massive beamforming, distributed MIMO, multi-user MIMO and beam tracking.

The more advanced testing follows basic 5G trials completed in the fall of 2016 by Ericsson and SoftBank in the 15 GHz and 4.5 GHz bands.

The trials will evaluate RF propagation on the 4 GHz, 4.5 GHz and 28 GHz bands, using new air interfaces  at speeds exceeding 10 Gbps with latency of less than 1 millisecond.

Tests will use a 100-megahertz channel in the 4 GHz band; a 200-megahertz channel in the 4.5 GHz band and a 732-megahertz channel in the 28 GHz band.

SoftBank said it aims to launch 5G commercial services around 2020.

IBM, Ericsson Design 28-GHz Phased-array Antenna

February 9, 2017 — IBM Research and Ericsson have created a compact silicon-based millimeterWave (mmWave) phased array antenna module designed for 5G base stations.

The 28-GHz antenna is the result of a two-year collaboration, which brought together IBM’s knowledge of highly integrated phased array mmWave integrated circuits and antenna-in-package solutions and Ericsson’s expertise in circuit and system design for mobile communications.

The module, which consists of four monolithic integrated circuits and 64 dual-polarized antennas, measures approximately 2.8 inches by 2.8 inches.

Another feature of the antenna reported by the team is concurrent dual-polarization operation in transmit and receive modes. This capability enables one phased array antenna module to form two beams simultaneously, doubling the number of users to be served at the same time and so improving the overall value and economics of the technology.

A major hurdle for the use of mmWave signals in mobile communications is achieving sufficient range between radios to support target applications. At 28 GHz, each antenna is tiny and individually would support short communication distances, but combining multiple such tiny antennas not only increases the range but also enables steering of signals in specific directions. The IBM and Ericsson team’s phased array design supports beam-steering resolution of less than 1.4 degrees for high precision pointing of the beam towards users.

 

Integrated Tower-top Design Boasts Zero Footprint

November 22, 2016 — Ericsson is launching a tower-top site design that enables operators to deploy a fully-integrated suite of radio and microwave, including 2G, 3G, 4G and 5G technologies, with zero footprint.

The integrated tower-top site design, developed by Ericsson’s Region Sub-Saharan Africa, addresses these challenges is a multi-band and multi-standard solution where baseband, radios, and antenna are combined using Ericsson’s latest radio system, and to which microwave backhaul can also be added. Finally, the system provides evolved RAN capability for capacity expansion and modernization.

Simply put, the system can be expanded without replacing the entire tower-top assembly.

“Using industry-standard elements, the site offers improved range, better sensitivity, increased capacity and expandability while weighing less and consuming less power. As a region, we are proud to have taken the lead in the development of this first of its kind design,” said Jean-Claude Geha, head of Region Sub-Saharan Africa at Ericsson

The tower-top site will be demonstrated at AfricaCom, Africa’s technology and ICT conference and is expected to be commercially available in Q3 2017.

Telia, Ericsson Demo High-Speed, Low-Latency System

October 18, 2016 — Telia, a mobile network in Sweden, and Ericsson have conducted outdoor tests of a trial system with the goal of rolling out a high-speed, low-latency system in Stockholm, Sweden, and Tallinn, Estonia, in 2018.

The trial in Kista, Sweden, used 800 megahertz of spectrum in the 15 GHz band. During the test peak rates of 15 gigabits per user, more than 40 times faster than 4G speeds, and a latency below 3 milliseconds were achieved.

While major deployment of 5G networks is not expected until 2020, development of pre-commercial products, testing and spectrum is ongoing. Telia Company and Ericsson’s partnership is conducting these trials to help drive the future global standards, according to Peter Laurin, head of region northern Europe & central Asia, Ericsson.

“Today marks an important step on our joint 5G roadmap for Sweden and Estonia. Our 5G roadmap will incrementally introduce IoT technologies and 5G concepts that will enhance end user experience and business potential for enterprises and society. Telia and Ericsson offer consumers and businesses to stay ahead with 5G-like services introductions. We are continuously creating new opportunities leveraging the promise of IoT and 5G and we’ll all experience it step by step,” Laurin said.

Ericsson’s Profit Plunges in Q3; More Cuts Loom

October 18, 2016 — Ericsson’s third quarter 2016 results will be significantly lower than company expectations, as profits plummeted 94 percent. An earnings warning last week caused the company’s stock to drop 20 percent, and it has almost been halved in the last 12 months.

Negative industry trends from the first half of the year have further accelerated, primarily in Segment Networks, according to Jan Frykhammar, president and CEO. The sales decline was mainly driven by weak markets, such as Brazil, Russia and the Middle East. In addition, capacity sales in Europe were lower following completion of mobile broadband projects in 2015.

Frykhammer said the current trends are expected to continue short-term, which will lead to more cost cutting at the carrier.

“Continued progress in our cost reduction programs did not offset the lower sales and gross margin,” he said. “We will continue to drive the ongoing cost program and implement further reductions in cost of sales to meet the lower sales volumes.”
