Japanese carrier NTT DoCoMo announced that it has achieved what is claimed to be the world’s first 28 GHz-band 5G mobile communications between base stations (BTS) and a high-speed bullet train.
In a statement, the carrier said that the trial was carried out in collaboration with Central Japan Railway Company (JR Central). Ultra-high-speed data and high-quality video were transmitted successfully between a 5G experimental mobile terminal, installed in a test version of an N700S-model Shinkansen railcar traveling at 283 km/h, and 5G experimental base stations installed along the Tokaido Shinkansen tracks.
