FCC unlocks new airwaves for vehicular radar use

The US Federal Communications Commission has expanded the spectrum available for vehicular radars that are used for a variety of purposes, including safety applications like collision avoidance and adaptive cruise control. The agency’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.

The US 2115 Federal Communications Commission has expanded the spectrum available for vehicular radars that are used for a variety of purposes, including safety applications like collision avoidance and adaptive cruise control.


The agency’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 customise the radars in vehicles for different markets.

“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,” the FCC said in a statement. “This action 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.”

    David Crawford welcomes low-cost safety initiatives for pedestrians in America. Some 10 people die each week in accidents on crosswalks in the US, that’s more than 10% of all pedestrian fatalities in road traffic incidents - the number of which is running at a five-year high. Ensuring crosswalks are safe is key in supporting the growing enthusiasm for walking as a travel mode. In the last decade of the 20th century, numbers walking to work in the US fell by 26%; while, as recently as 2012, Americans were e

    User-based insurance is blazing a trail others would like to follow and is also discovering the challenges. The ITS sector needs to keep a very careful eye on the automotive industry: “There’s a war going on in the connected car space creating richer datasets than we ever imagined possible” says Paul Stacy, research and development director of Wunelli, part of the LexisNexis group. The car makers have gone way beyond infotainment, unlocking huge amounts of data in the process … facts and figures which the i
