The 79 GHz coordination and support action aims to establish and speed up the worldwide harmonised frequency allocation for automotive radar systems in the frequency range 77 GHz to 81 GHz (79 GHz) by country specific activities and a global Automotive Radio Regulations Expert Group (GARREG).

The awareness of the significant contribution of high resolution automotive radar to passenger and pedestrian safety is constantly increasing: administrations and other regional and international organisations currently include 79GHz high resolution automotive radar in their considerations.

In February 2014, the recommendation ITU-R M.2057 (“Systems characteristics of automotive radars operating in the frequency band 76-81 GHz for intelligent transport systems applications”) containing the technical characteristics of high resolution automotive radar systems has been approved. This milestone will boost the ongoing country specific activities which are currently mainly focused on USA, Brazil, China and India.
