Abstract: A system includes antenna circuits void of transceivers, a multiplexer connected to the antenna circuits, a transceiver and a control module. The transceiver is connected to the multiplexer and cycles through the antenna circuits to facilitate determination of a location of a portable access device relative to a vehicle. The transceiver allocates periods of time for each of the antenna circuits and during each period of time exchanges radio frequency signals with the portable access device to obtain timing information associated with transmission of the radio frequency signals or a range estimate of the portable access device relative to the vehicle. The range estimates are estimates of distances between the antenna circuits and the portable access device. The location is determined based on the timing information or the range estimates. The control module, based on the determined location, provides access to the vehicle or control of a vehicle system.
