5G-Crosshaul Partners Announce Successful Result of 5G Integrated Fronthaul-Backhaul Extended Outdoor Trial
Month-plus trial in real-world conditions, a first of its kind, delivers sub-millisecond latency, Gbps throughput; integrated fronthaul/backhaul sets stage for cost saving, flexibility in real-world deployable 5G architecture

BERLIN, Germany, Nov. 09, 2016 (GLOBE NEWSWIRE) -- InterDigital (NASDAQ:IDCC), Fraunhofer Heinrich Hertz Institute HHI, and Core Network Dynamics (CND), three partners from the H2020 5GPPP 5G-Crosshaul consortium, today announced the successful result of an extended, real-world deployment of an integrated fronthaul/backhaul network delivering 5G throughput and latency. The test, a first of its kind, sets the stage for cost-effective, highly flexible 5G network architecture.

The results of the integrated millimeter wave (mmW) fronthaul/backhaul 5G Berlin Testbed were announced at the November 2nd IEEE 5G Berlin Summit and will be further presented at the 5G-PPP Global 5G event, taking place today and tomorrow in Rome. The 5G-Crosshaul test was carried out over more than a month at the Fraunhofer Heinrich Hertz Institute in Berlin, and delivered higher than 1.2 Gbps throughput and less than millisecond latency. Beyond the speed, the test’s integrated fronthaul/backhaul provides a working model for future 5G networks that will combine 4G architecture with a 5G fronthaul-based network edge. With this deployment, 5G radio network solutions can be implemented using commodity servers or even in the cloud – a major innovation that throws open the doors for new operator models.

The 5G Berlin Testbed is a 5G field trial of InterDigital’s EdgeLink™ 60GHz solution, multiplexing both backhaul and CND’s Cloud-RAN next generation fronthaul solution over an integrated mmW mesh transport network. The system is installed outdoors, executing under environmental conditions from the end of September through November. The trial has included both natural and induced link failure events, to test network resiliency.

“Millimeter wave technology will be a decisive cornerstone to bring 5G forward to enhanced mobile broadband harvesting new spectrum opportunities well above 6GHz, ultra-dense deployments and energy-efficient multi-Gigabit transmission,” explains Dr. Thomas Haustein, Head of Department for Wireless Communication and Networks at Fraunhofer HHI.

“The 5G Berlin Testbed will provide valuable information that can be used to help advance the evolving 5G standards and specifications. We are already adapting OpenEPC to support critical 5G requirements. These include a distributed core network, plus architectures to support C-RAN and the cloudification of the radio access network,” said Carsten Brinkschulte, CEO, Core Network Dynamics.

“Many companies have demonstrated systems that they qualify as ‘5G’ because of speed or latency characteristics, but this extended outdoor trial is the first example of a network edge architecture, tested in real-world conditions, that will be a key in eventual 5G deployment,” said, Alan Carlton, Vice President, InterDigital Europe. “Crosshaul’s major innovation may set the stage for a world where our definitions of what constitutes a network operator or infrastructure equipment are radically changed.”

5G-Crosshaul is an international project with 21 members aimed at developing integrated fronthaul and backhaul system solutions to support flexibility and unified management for 5G network architectures. To learn more about the project, visit http://5g-crosshaul.eu/.
