Applications”
MIC has been actively promoting WRC‐15 Agenda Item 1.18 ‘79GHz band high‐resolution radar’.
14
WRC-19: Proposal of Agenda Item
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
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!
