KDDI, Samsung Demo 5G on High-Speed Train

Telecom company KDDI and Samsung Electronics say they successfully completed the first 5G demonstration on a moving train. The trial shows the possibilities of 5G capabilities, including high throughput, low latency and massive connections. The actions could pave the way to improved backhaul for onboard WiFi, better passenger infotainment and increased security and analytics, the companies believe.

The tests, carried out near Tokyo, used Samsung’s 5G pre-commercial end-to-end technology; it’s composed of a 5G router (CPE), radio access unit (5G Radio), virtualized RAN and virtualized core. The companies achieved a successful downlink and uplink handover on the train traveling at over 60 mph; The peak speed was 1.7 Gbps.

In addition, 8K video was downloaded via the 5G router, and a 4K video, filmed on a camera mounted on the train, was uploaded. The distance between two stations was nearly one mile.  

The demo fits in with KDDI’s goal to deploy 5G by 2020. The successful demonstration “in everyday locations such as a train and a train station is an important milestone indicating 5G commercialization is near,” said Yoshiaki Uchida, Senior Managing Executive Officer at KDDI.

KDDI and Samsung Electronics have been jointly demonstrating 5G millimeter wave performance in various scenarios since 2015. They plan to continue, including “research on diverse spectrums and technologies, as well as new business models and applications,” according to Samsung President and Head of Networks Business Youngky Kim.
