KDDI and Samsung recently showcased peak speed of 1.7 Gbps in a 5G demonstration on a moving train traveling at over 100 km/hour (over 60 mph) in the city of Saitama in Japan, near Tokyo.
This was achieved along a section of track where the distance between two stations was approximately 1.5km (nearly 1 mile).
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, 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.
In September, KDDI and Samsung joined hands to complete a series of 5G millimeter wave tests at speeds over 190km per hour in Korea. The test measured and evaluated a variety of metrics, including handover interruption time, uplink and downlink throughput stability, and latency stability over a vehicle accelerated from 0 to 205km per hour on the race track between multiple 5G base stations.
