Japan’s Ministry of Internal Affairs and Communications (MIC) has collaborated with Japanese telecom provider NTT DOCOMO, Japanese commuter railway company Tobu Railway and Chinese ICT solutions provider Huawei to conduct 5G field trials in Tokyo Skytree Town, a modern commercial center in the Sumida District of Tokyo that was opened in May 2012.

The system trial was conducted as part of NTT DOCOMO’s contract of MIC’s 5G field trial with an aim to research technical conditions to use the 28GHz band and other candidate spectrums for 5G in dense urban areas by investigating radio propagation characteristics as well as evaluating 5G system performance with focus on enhanced Mobile Broad Band (eMBB) applications.

In December 2017, Huawei had succeeded in 5G long-distance and high-speed data transmission between Tokyo Skytree Tower and a shopping facility at Tobu Railway’s Asakusa Station on the 28GHz band together with NTT DOCOMO and Tobu Railway.

Huawei also evaluated 5G system performances when creating an immersive video communication with clear voice calls and smooth video footage by using Microsoft HoloLens connected to the end-to-end 5G network used for the long-distance and high-speed data transmission.

Huawei, as a partner of NTT DOCOMO’s 5G experimental trial and contract of MIC’s 5G Field Trial, said it will continue to evaluate 5G data transmission and system performance required for video communication services toward Tokyo 2020 Olympic and Paralympics Games and beyond.
