As described in a previous column (“Activities on Legislation for Autonomous Vehicles Take Off [Connectivity: The U.S. 5.9-GHz Spectrum],” IEEE Vehicular Technology Magazine, Volume 16, Issue 3), ITS America and the American Association of State Highway and Transportation Officials (AASHTO) filed a lawsuit in June 2021, with the intention of reversing the U.S. Federal Communications Commission’s (FCC’s) reallocation of 45 MHz from ITS to Wi-Fi.

ITS America states that it has demonstrated that the full range of V2X applications—including sensor sharing and cooperative maneuvering, which are important for enhancing automated vehicle safety, as well as safety applications for vulnerable road users—would be unable to fit within the remaining 30-MHz spectrum environment.

In March 2022, ITS America and the AASHTO presented oral arguments to the United States Court of Appeals for the District of Columbia Circuit, evoking the FCC’s order to reallocate the majority of the spectrum in the 5.9-GHz band for use by unlicensed devices.
