WRC-19: Proposal of Agenda Item 15 Global harmonization of frequency bands for ITS applications in the land mobile service Background: Considering possible interference sharing spectrum with DSRC/ITS and RLAN (Wi-Fi). APG15-4 (February 2015, Bangkok): Proposed by Japan Future work: If it is approved as a new Agenda Item (A.I.) in WRC-15, we have to work together toward WRC-19. Requires global support for this WRC 19 Agenda Item, especially from Europeans and Americas.
Summary 16 1. Autonomous driving is key word for ITS in Japan. 2. In accordance with the New ICT Strategy, SIP included three ITS projects which have been promoting R&D by MIC. 3. 700MHz band ITS services will be deployed in Japan within this year. 4. 79 GHz band high-resolution automotive radar will be deployed worldwide after WRC-15. 5. Japan proposed a WRC-19 agenda item on Global harmonization of ITS Spectrum to APG. Let s work together!
