FCC Modifies C-V2X Joint Waiver Conditions
The FCC lifted one of the restrictions, limiting on-board units (OBUs) to 20 dBm transmitter output power, that was part of the joint waiver allowing some proponents of cellular-vehicle-to-everything in the 5.9 GHz band to start to deploy. The FCC…

Petitioners are correct that NTIA “recommended limits it deemed sufficient to protect federal systems from potential interference from C-V2X operations, in terms of [equivalent isotropic radiated power], during the waiver period, and did not require a Transmitter Output Power limit,” the Wednesday order said: “We also note that the Commission has moved away from defining the transmitter output power limit and antenna gain requirement in recent rulemakings in order to provide product design flexibility to manufacturers.” The waiver conditions aren’t “intended to add unnecessary burden or constraint on the deployment of C-V2X-based technology,” the FCC said. The order was handed down by the chiefs of the Public Safety and Wireless bureaus and the Office of Engineering and Technology.
