Samsung partners with KDDI for the first 5G demo on a high-speed train

Samsung Electronics has partnered with Japanese telecommunications operator KDDI for the first demonstration of 5G on a high-speed train.

The partners conducted the world-first test on a train traveling at over 100km/h (over 60 mph) along a section of track where the distance between two stations was approximately 1.5km (nearly 1 mile).

While the distance is not as far as what consumers will be hoping for in terms of coverage along transport routes, it nevertheless shows that high-speed 5G data can be delivered to high-speed vehicles.

During the demonstration, the companies achieved a successful downlink and uplink handover as well as a peak speed of 1.7 Gbps. It was conducted in the city of Saitama in Japan, near Tokyo.

As 5G is yet to be finalised, KDDI used Samsung’s pre-commercial end-to-end solution composed of a 5G router (CPE), radio access unit (5G Radio), virtualised RAN, and virtualised core.

Yoshiaki Uchida, Senior Managing Executive Officer at KDDI, says: “In collaboration with Samsung, KDDI has opened up the possibility for new 5G vertical business models, such as a high-speed train. 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 a train station is an important milestone indicating 5G commercialisation is near."

“To fulfill our aim to launch 5G by 2020, KDDI will continue exploring real-life scenario experiments for diverse 5G use and business cases together with Samsung.”

KDDI and Samsung tested potential new use cases for such high-speed mobile connectivity including uploading 4K video taken from a camera mounted on the train. An 8K video was downloaded via the on-board CPE showing the potential for operators and passengers alike.

“The potential that 5G holds is powerful enough to transform the landscape of our daily lives,” said Youngky Kim, President and Head of Networks Business at Samsung Electronics. “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.”
