Abstract: A wireless communication system for a vehicle includes a wireless access point (AP), an ultra-wide band (UWB) system, a communication link, a controller, and a vehicle system. The UWB system is in communication with the wireless AP via a communication link. The wireless communication system is operable to detect, via the wireless AP, a request for localized wireless communication. The UWB system requests the wireless AP to generate a clear to send (CTS) transmission, which includes selecting an ultra-wide band (UWB) channel, mapping the UWB channel to a plurality of WiFi channels, and transmitting, by the wireless AP, the CTS transmission to each of the plurality of WiFi channels. The UWB system then transmits a UWB message.
