The Federal Communications Commission (FCC) last week expanded the spectrum available for vehicle radars that are used for a variety of purposes, including safety applications like collision avoidance and adaptive cruise control. Access to this additional spectrum will enable continued innovation in this space, allowing these radars to better distinguish between objects in areas close to the vehicle, according to FCC.
The Commission’s action expands the current 76-77 GHz spectrum allocation to include the entire 76-81 GHz band and transitions radars out of the 24 GHz band. This is consistent with the spectrum that is available internationally, avoiding the need to customize the radars in vehicles for different markets.
The new spectrum will improve performance for applications such as lane change warnings, blind spot detection, parking aids, stop and follow, stop and go, autonomous braking, and pedestrian detection.
