1. A method for controlling wireless communication on-vehicle, the method comprising:
detecting, via an on-vehicle wireless access point (AP), a request for localized wireless communication;
requesting, via an ultra-wide band (UWB) system, the wireless AP to generate a clear to send (CTS) transmission, including:
selecting an ultra-wide band (UWB) channel,
mapping the UWB channel to a plurality of WiFi channels, and
sequentially transmitting, by the wireless AP, the clear to send (CTS) transmission to each of the plurality of WiFi channels; and
transmitting, via the UWB system, a UWB message in response to the request for localized wireless communication.
