    JRC, in collaboration with Nisshinbo Brake Inc., has implemented a Sub-6 GHz local 5G system at the Asahi Test Course in Chiba, Japan, enhancing automotive brake performance testing. This private 5G system enables real-time data transmission, remote monitoring, and control, significantly improving test efficiency. By facilitating seamless communication between the test course and the technical development center in Tatebayashi, accelerates decision-making and shortens the R&D cycle.

    Challenge

    Nisshinbo Brake researches friction materials and other components at the Asahi Test Course in Asahi City, Chiba. The combinations of materials are numerous, and multiple test runs are required before a product can be developed. Under the traditional method, after completing a test drive, data collected from the test vehicle had to be recorded onto a USB drive, transferred to an office computer, and then analyzed. This process hindered the speed of development.

    Solution

    With the introduction of JRC’s Private 5G System, data collected from test vehicles is now transmitted in real time to the office, enabling on-the-spot analysis. This system also allows for the transmission of high-definition camera footage of road conditions and real-time voice communication between test drivers and engineers, facilitating immediate adjustments to the test process. Furthermore, test results can be shared instantly with engineers at Nisshinbo Brake's Tatebayashi facility, speeding up development and improving collaboration across locations.

    Value Proposition

    JRC developed a high-gain antenna with sharp directional characteristics that are ideal for narrow, linear communication areas like the Asahi Test Course. This antenna enables efficient coverage of the course, which spans approximately 1.4 km, using just one base station. Additionally, JRC’s proprietary Doppler correction technology ensures stable, low-latency communication even during high-speed testing (up to 120 km/h), meeting Nisshinbo Brake’s stringent requirements for real-time data transfer.
