KDDI and Samsung Electronics have completed the first 5G demonstration on a moving train traveling at over 100 km/hour (over 60 mph).

This was achieved along a section of track where the distance between two stations was approximately 1.5km (nearly 1 mile). During the demonstration, the companies achieved a successful downlink and uplink handover as well as a peak speed of 1.7 Gbps.

The tests were carried out from October 17th through the 19th in the city of Saitama in Japan, near Tokyo. For the tests, Samsung's 5G pre-commercial end-to-end solution was used, which is composed of a 5G router (CPE), radio access unit (5G Radio), virtualized RAN and virtualized core.

In addition to a successful downlink and uplink handover, 8K video was downloaded via the CPE installed on-board, and a 4K video, filmed on a camera mounted on the train, was able to be uploaded.

Since 2015, KDDI and Samsung Electronics have been collaborating to demonstrate 5G millimeter wave performance in various scenarios. This includes a multi-cell handover demonstration that took place in February, where the device was mounted on a car that traveled in the busy streets of Tokyo, and a high-speed mobility test with the device attached on a car racing at 200km/h in Yongin, Korea in September.
