Alliance Supports Tesla Proposal to Use UWB for Vehicle Charging

The Ultra Wide Band (UWB) Alliance supported a Tesla request for a waiver of FCC rules to allow authorization for a UWB positioning system operating in the 7.5-8.5 GHz frequency range to be used for wireless charging of electric vehicles. The FCC Office of Engineering and Technology sought comment last month, due Monday in docket 25-101 (see 2502250037). Tesla’s proposed use of UWB for peer-to-peer communication and ranging “leverages the unique capabilities of UWB to precisely position the vehicle," the filing said: “UWB is optimal technology for this use, with superior performance, at a very small fraction of the transmit power and thus potential for disruptive interference, compared to other available technologies.”
