Introduction
Japan's Terrestrial Radiocommunications Commission has issued a draft report outlining proposed technical conditions for the use of the 433 MHz band for Tire Pressure Monitoring Systems (TPMS) and Remote Keyless Entry (RKE) systems. The report aims to modernize low-power wireless systems by establishing standards for these applications.
Current Landscape
Currently, most vehicles in Japan utilize TPMS and RKE systems operating in the 315 MHz band. However, to align with international practices—where the 433 MHz band is commonly used, as seen in the US and EU—Japan is considering harmonizing its frequency use. This strategic move seeks to facilitate the import and export of vehicles and enhance compatibility with global standards.
Technical Conditions
The draft report details technical conditions for operating TPMS and RKE systems in the 433 MHz band, addressing coexistence with other radio services, such as amateur radio and international transport tag systems, to prevent interference.
Public Consultation
Public consultation on the proposed technical conditions for the 433 MHz band will run from September 7, 2024, to October 7, 2024. Feedback during this period will be crucial in shaping the final guidelines.
Implications
Adopting the 433 MHz band for these systems could improve vehicle compatibility and safety standards in Japan's automotive sector, aligning it with international standards and practices.
