Fujikura Succeeds in 60 GHz Band High-Speed Communication Experiment in Safe Driving Support Test

Fujikura Ltd. has successfully demonstrated high-speed vehicle-to-infrastructure communication using an electric pole and in-house developed 60 GHz millimetre-wave wireless communication modules in a demonstration of safe driving support. The project was conducted in Himeji City, Hyogo Prefecture, for four days from March 15 to 18, 2021, in a corporation with Kansai Transmission and Distribution, Inc., KYOCERA Corporation, Shinki bus Co., Ltd., Panasonic System Networks R&D Lab. Co., Ltd. and Magellan Systems Japan, Inc.

The demonstration confirmed the effectiveness of the safe driving support system for local bus services by vehicle-to-infrastructure communication using an electric pole and vehicle-to-vehicle communication with bicycles at intersections with poor visibility without traffic lights. This safe driving support demonstration using a local bus in service will be the first of its kind in Japan.

In this demonstration, Fujikura installed a communication device equipped with the module on electric poles and a local bus to establish a wideband wireless connection between the two. By using the wireless connection, the module has successfully uploaded in-vehicle camera images in real-time. It has also transmitted the GNSS (global navigation satellite system) correction data necessary for high-precision vehicle positioning required for supporting safe driving.

Fujikura says its module featuring world-class high communication speed (>2Gbps) and long-distance transmission capability (>500 m) has also enabled immediate connection for mobile communication. Consequently, they say it will accelerate their studies by applying this technology to various V2X (vehicle-to-everything) systems. The systems to be incorporated in transportation-related vehicles such as general vehicles, buses and trucks, construction/work vehicles, and AGVs (automatic guided vehicles) used in factories.

To have this module evaluated outdoors, the company plans to provide early adopters with the “outdoor evaluation kit” to be used as a communication device for demonstrations from 2Q 2021CY. This kit will contain the module and a control processor enclosed in a case for outdoor use and is equipped with a functional network interface of 2×1 Gbps Ethernet.
