NTT Docomo: First 5G Communication Between Bullet Train and Base Station akihabaranews.com

NTT Docomo (Tokyo) — NTT Docomo, Inc., announced today that it has achieved what is believed to be the world’s first 28 GHz-band 5G mobile communications between base stations and a high-speed bullet train during experimental trials to verify further enhancement of 5G in collaboration with Central Japan Railway Company (JR Central).
Since its opening, the Tokaido Shinkansen has been used by about 5.6 billion people and has supported Japan’s economic growth.
The trials verified successful 5G wireless data transmissions at speeds exceeding 1.0 Gbps and consecutive handover among three base stations located along the tracks.
The transmissions were facilitated with advanced beamforming and beam tracking technologies incorporated in the 5G experimental mobile and base stations.
Going forward, Docomo will continue to challenge to realize fast, stable 5G mobile communication in a wide range of mobile environment including bullet train.
