Kyocera and JMA Wireless recently announced that they have formally agreed to develop a 5G millimeter-wave backhaul system.
The 5G millimeter-wave backhaul system will connect donor stations and relay node stations for quick and effective deployment of 5G base stations in areas where fiber is either not available or too costly. The system will use O-RAN interfaces, making it possible to connect to various 5G networks.
5G services are in full swing, and there is the need to quickly densify 5G service areas. Normally, 5G base stations are connected to the 5G core network via fiber optic cables, but in rural areas and suburban areas it is expected that fiber trenching on the last mile will be expensive and time-consuming to realize. Therefore, 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 solution will simplify the installation, integration and operation of 5G base stations, contributing to a rapid growth of 5G radio sites.
In addition, SoftBank knowledge on network quality and fiber transport requirements, will contribute to the development of products that meet customer needs in Japan and overseas.
By combining Kyocera's long track record in wireless base station technology development with JMA’s innovative virtualized baseband technology (XRAN), Kyocera aims for an early market launch for the 5G backhaul system. 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. We plan to launch this system in the fiscal year 2022.

We are pleased to announce that Kyocera has reached an agreement with JMA to jointly develop a new telecommunications infrastructure system business. Kyocera intends to contribute to the development of 5G infrastructure systems providing our revolutionary 5G millimeter-wave backhaul system to SoftBank and various other carriers.
Remo Ricci, Managing Director and Head of International Sales, JMA Italy
JMA is looking forward to working with Kyocera to bring this revolutionary 5G millimeter-wave backhaul system to carriers like SoftBank in the near future.
