Docomo Achieves World's First 5G Communication Between Bullet Train and Stations

NTT Docomo Inc says it achieved the world's first 5G mobile communications between base stations and a high-speed bullet train during experimental tests to verify further enhancement of 5G in collaboration with the Central Japan Railway Company (JR Central).

High-speed data and high-quality video were successfully transmitted between an experimental 5G mobile terminal, installed on a trial version of a model N700S shinkansen wagon, traveling at 283 km / h, and temporarily mounted 5G experimental base stations along the Tokaido shinkansen tracks.

Tokaido shinkansen is Japan's premier transportation corridor, connecting the metropolises of Tokyo, Nagoya and Osaka, and is the longest running Shinkansen line, having opened as the world's first high-speed rail on 1 October 1964.

Since its inception, Tokaido shinkansen has been used by about 5,6 billion people and has supported Japan's economic growth. The N700S used in the trial is JR Central's next-generation shinkansen model, which will be commercially launched in Japan on 2020.

Experimental tests were conducted in Japan between Mishima and Shin-Fuji stations in the Fuji area of ​​Shizuoka Prefecture between August 24 and September 7, while the wagon traveled at 283 km / h.

The tests found successful 5G wireless data transmissions at speeds in excess of 1,0 Gbps and consecutive delivery between three base stations located along the tracks. Transmissions were facilitated with advanced beamforming and beam tracking technologies built into the 5G experimental base and mobile stations.

In addition, ultra-high-definition 8K video content was quickly downloaded from base stations for delivery to the wagon's mobile terminal and scenario 4K video was streamed live from the wagon's mobile terminal to base stations.
