Beschreibung
Zusammenfassung:	A sensor is configured to receive connection information from a portable device via a communication gateway in a vehicle and to communicate with a portable device using impulse radio (IR) ultra-wide band (UWB) communication based on the connection information. A location of the portable device is determined based on ranging using IR UWB communication.
