KDDI and Samsung Electronics have joined hands to complete a series of 5G millimeter wave tests at speeds over 190km per hour in Korea.
Claiming as the fastest record in the world, the successful results highlight the potential and capability of 5G to support a wide variety of future service scenarios.
The demonstration involved a battery of individual tests to examine the performance of Samsung’s end-to-end 5G mmWave technology. Specifically, as a vehicle accelerated from 0 to 205km per hour on the race track between multiple 5G base stations, the test measured and evaluated a variety of metrics, including handover interruption time, uplink and downlink throughput stability, and latency stability (or “jitter”).
In addition, KDDI and Samsung also demonstrated a successful handover scenario, with Samsung’s 5G device attaching to the 5G base station as it approached the service area, and successfully being handed over to the target cell at a speed of 192km per hour (GPS speed).
The test achievements build upon a string of mobility-related successes over the past several years. In February of this year, Samsung and KDDI successfully demonstrated 5G handover capability in an urban city environment at speeds of up to 60km/h on public roads. Both companies are in discussion with 5G trials for multiple 5G service cases.

Until now, peak bandwidth has been the common refrain, and certainly a big component of the future of 5G. However, the test we conducted with KDDI will help us build a more diverse portfolio of future 5G use cases.

The trial successfully showcased stable performance under high-speed mobility conditions which will dramatically increase the service experience of users in vehicles.
