Wireless / V2X

Successful safe driving support demonstration – first of its kind in Japan

Sivers Semiconductors is proud to be at the heart of innovation, this time in a successful customer demonstration of high-speed vehicle-to-everything (V2X) communication using WiGig mmWave technology for unlicensed 5G by our partner Fujikura Ltd. in Japan.

The demonstration was conducted during four days in March 2021 using a local bus in service in Himeji City, Hyogo Prefecture, and was the first of its kind in Japan. The experiment was done in co-operation 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 purpose was to confirm the effectiveness of a safe-driving support system for local bus services, by leveraging vehicle-to-infrastructure communication and vehicle-to-vehicle communication between the bus and approaching bicycles at intersections with poor visibility and no traffic lights.

For the purpose of the demonstration, Fujikura had installed wireless communication devices equipped with their 60 GHz mmWave Wireless Communications Module (#SiversInside) on electric poles in the streets and on a local bus. This established wireless high-speed connectivity between the two.

By using the wireless connection, the module successfully transferred in-vehicle camera images in real time as well as GNSS (global navigation satellite system) correction data, which is required for high-precision vehicle positioning and to support safe driving.

Fujikura plans to accelerate their studies of applying this technology to various V2X systems to be incorporated into transportation-related vehicles such as general vehicles, buses, trucks, construction/work vehicles, and automatic guided vehicles (AGVs) used in factories.

Fujikura’s 60 GHz mmWave Wireless Communications Module is based on the IEEE 802.11ad (WiGig) standard, and integrates Sivers Semiconductors’ RFIC (TRXBF01) for unlicensed 5G.
