    TOKYO, Jan 28, 2021 - (JCN Newswire) - NTT DOCOMO, INC. and East Japan Railway Company (JR East) jointly announced that they have verified the stable operation of important 5G communication capabilities, including handover between base stations and the transmission of high-definition video data, in trials conducted aboard JR East's ALFA-X(1) Shinkansen test train running at 360km/h.
  • The trials confirmed that it will be possible to ensure stable mobile communication environments on high-speed trains for the delivery of high-value mobile services.
  • DOCOMO has been working to confirm the feasibility of 5G communication in high-speed environments since 2017.
  • In general, communication quality at high speed becomes unstable due to the influence of direct-path obstructions and the Doppler effect.
