DOCOMO hits >1Gbps speeds in 5G mmWave bullet train trial

1 Oct 2019

NTT DOCOMO of Japan’s latest 5G trials delivered data speeds of over 1Gbps to a moving vehicle – this time a next-generation Shinkansen bullet train – as the Japanese cellco successfully answered the question over whether mmWave-based 5G networks will be able to deliver services to customers using fast-moving transport systems. In announcing what it claims is a ‘world first’, DOCOMO said it completed a multi-base station handoff of 5G signals to a device on the Shinkansen bullet train travelling in excess of 170mph, including transmitting 8K video from the network to the mobile device, and streaming 4K video live from the mobile device to the network. In the trial, the cellco used three 28GHz mmWave base transceiver stations equipped with advanced beamforming and beam-tracking features capable of conveying and handing off ultra-high speed data signals while the train was in motion. The test took place between Mishima and Shin-Fuji stations, the cellco reported.
