Kyocera and JMA Wireless have agreed to develop a 5G millimeter-wave backhaul system. The system will connect donor stations and relay node stations for deployment of 5G base stations in areas where fibre is either not available or too costly. The system will use O-RAN interfaces, making it possible to connect to various 5G networks.
Kyocera and JMA’s system will use multi-beam technology with Kyocera’s multi-element antennas for donor stations to develop a multi-cell system that simultaneously connects multiple relay node stations with 5G millimeter-wave wireless backhaul circuits. The resulting service is expected to simplify the installation, integration and operation of 5G base stations, contributing to a rapid growth of 5G radio sites.
In addition, SoftBank's knowledge on network quality and fibre transport requirements, will contribute to the development of products that meet customer needs in Japan and overseas.
By combining Kyocera's track record in wireless base station technology development with JMA’s virtualized baseband technology (XRAN), Kyocera aims for an early market launch for the 5G backhaul system.
Future development plans
Kyocera and JMA have discussed with SoftBank the development of this technology and are considering support for field trials on a commercial aircraft using SoftBank's network. The partners plan to launch this system in the fiscal year 2022.
