According to recently(24th April) published report in Reuters, The Federal Communications Commission (FCC) on Monday approved a request by U.S. state agencies, some automakers, universities and others to use spectrum to deploy connected vehicle technology to prevent crashes, especially at intersections.
The 5.9 GHz spectrum block was reserved in 1999 for automakers to develop technology for vehicles to communicate with each other to avoid crashes but has so far gone largely unused.
