Samsung And KDDI Demos 5G Technology While On A Moving Train Achieved A Track Record 1.7Gbps Speed

KDDI and Samsung Electronics have announced a successful completion of a comprehensive set of 5G tests that demonstrated on a moving train which is traveling at a speed of 100km/hour and the distance between two stations was almost 1.5kms. During the demonstration, it drives breakthrough as 5G uplink and downlink handover – and achieved peak 1.7Gbps speed. All this achieved on a high-speed train traveling over 100 kilometers per hour or over 60mph.


Both have successfully completed the first 5G demonstration on a moving train traveling at over 100 km/hour. This was achieved along a section of track where the distance between the two stations was approximately 1.5km (almost 1 mile). The tests were carried out from October 17th through the 19th in the city of Saitama in Japan, near Tokyo.

Samsung has used its 5G pre-commercial end-to-end solution for the tests, which is composed of a 5G router (CPE), radio access unit (5G Radio), virtualized RAN and virtualized core. The 5G demonstration involved a battery of individual tests to examine the performance of Samsung’s end-to-end 5G mmWave technology.

In addition to the downlink and uplink handover, an 8K video has also been downloaded via the CPE installed onboard, as well as a 4K video, filmed on a camera mounted on the running train. The same was able to be uploaded while testing.

The demonstration, however, leveraged capabilities are driven by 5G, such as high throughput, low latency and massive connections, which by means, verified potential services and use cases that would be apparently high-beneficial to passengers and operators of high-speed trains. This could finish the way to vastly improved backhaul for onboard WiFi, superior passenger infotainment and increased security and analytics.

KDDI and Samsung Break Track Record in High-Speed 5G Mobility Test

Youngky Kim, President and Head of Networks Business, Samsung Electronics said:

The potentials that 5G holds is powerful enough to transform the landscape of our daily lives. 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.

Yoshiaki Uchida, Senior Managing Executive Officer, KDDI said:

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 commercialization 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.

Since 2015, KDDI and Samsung have been closely collaborating to demonstrate 5G millimeter wave performance in various sectors (scenarios). This includes a multi-cell handover demonstration that took place in February this year, where the device was attached (mounted) on a car that traveled in the busy streets of Tokyo (link), and a high-speed mobility test with the device attached to a car racing at 200km/hour in Yongin, Korea in September, here’s the link to check out.
