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.

Yoshiaki Uchida, Senior Managing Executive Officer, KDDI
With 5G expected to bring railway services to a whole new dimension, the success of today’s demonstration in everyday locations such as a train and train station is an important milestone indicating 5G commercialization is near.

Youngky Kim, President and Head of Networks Business, Samsung 
The success of today’s demonstration is a result of our joint research with KDDI, which we will continue to pursue as we explore next generation networks and use cases. This will include research on diverse spectrums and technologies, as well as new business models and applications.
