Sony and Mitsui cooperate on spectrum sharing for enterprises

By Wireless Watch Staff

Two Japanese companies, Sony and Mitsui, have demonstrated dynamic spectrum access in a 5G Standalone network, and signed a memorandum of understanding to conduct joint studies into the commercial potential for the technology.

The trial used Sony’s Dynamic Spectrum Access (DSA) technology, working with Airspan 5G SA base stations and third party core. DSA assigns available spectrum channels in real time while suppressing radio interference. Sony is also one of the authorized spectrum access system (SAS) administrators for the USA’s shared CBRS spectrum, along with others such as Google and Federated Wireless.

Mitsui’s involvement comes via its Mitsui Knowledge Industry subsidiary, which is working with Japanese industries to offer ‘Local 5G’ private networking services.

The two companies aim to build a spectrum sharing model specifically for industrial usage, which could be easily adapted for many regions such as Japan, other parts of Asia, the USA and Europe.
