Kyocera and JMA Wireless to Develop 5G Millimeter-Wave Backhaul System
 Nov 05, 2021|View:69

Kyocera Corporation and JMA Wireless have formally agreed to develop a 5G millimeter-wave backhaul system. 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 Corp. (“SoftBank”)'s 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.

System Features

Reduces installation time and cost

Enables wireless last one mile for 5G connection, thus reducing the time and cost of base station installation to help quickly and inexpensively establish 5G coverage.

Compact size, lightweight, and low power consumption

Leveraging Kyocera decades of experience in base station technology development, we aim to save space, simplify installation, and reduce the power consumption required for the system.

Virtualized baseband technology (XRAN)

Multi-simultaneous connections between donor and relay node stations are realized by combining radio control with Kyocera’s multi-beamforming technology and JMA’s virtualization baseband technology. JMA’s virtualization baseband technology is also used for the relay node stations, enabling flexible system extension that helps to reduce operating costs.

Kyocera will develop the system and radio equipment and JMA will develop the XRAN part of the 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.
