KDDI, Samsung demonstrate 28GHz 5G handover in Tokyo

24 Feb 2017

KDDI and Samsung Electronics have announced that they have successfully completed a 5G handover trial on a highway in Tokyo. The two companies claim that the action represents Japan’s first ever 5G multi-cell handover test using 28GHz spectrum. The 5G handover was carried out in a test divided into two scenarios. First, a 5G device mounted on a vehicle that travelled at a speed limit of 60kmph drove between two 5G base stations on a metropolitan expressway. The second scenario was designed to verify the characteristics and performance of the 28GHz spectrum in Line of Sight (LoS) and Non Line of Sight (NLoS) environments. At the LOS environment, the vehicle drove through the heart of the city, and a maximum throughput of 3.7Gbps was achieved. Handover between 5G base stations is a required element to maintain a seamless data connection during a user’s movement between base station coverage, making it a critical enabler of 5G commercialisation.

TeleGeography notes that KDDI and Samsung signed a Memorandum of Understanding (MoU) to collaborate on next-generation 5G technologies back in November 2015.
