SKT, Ericsson, BMW carry out first multi-vehicular 5G trials

17 Nov 2016

SK Telecom (SKT), Ericsson and BMW have announced what they described as ‘the most advanced 5G outdoor mobility trial, including the first multi-vehicular 5G trials’. In a press release outlining the development, it was revealed that the trial was conducted successfully on a 5G test network installed at the advanced BMW car test track in Yeongjong-do, South Korea. SKT and Ericsson jointly deployed network slicing and 5G radio network infrastructure to cover a complete track in the BMW driving centre, and the trial with the connected test cars was said to have demonstrated that 5G performance will support V2X (Vehicular Connectivity) services that require low latency and consistent high bi-directional throughput.

The test environment was realised by using an Ericsson 5G field trial network consisting of multiple radio transmission points on 28GHz frequency band to cover the entire track and one user equipment installed in every car. With the trials said to have shown consistent Gbps-level throughput with a few millisecond latencies, uninterrupted connectivity using beam tracking and beam transfer across the different transmission points at speeds exceeding 100 kilometers per hour was also achieved. Further, the trial simultaneously implemented new key 5G capabilities with multi-site, multi-transmission point, MU-MIMO, and with multiple devices operating in the millimeter wave frequency band.
