The control module: transmits via the transceiver the first challenge signal to a vehicle, where the first challenge signal is associated with a passive entry or a passive start operation of the vehicle, based on the first challenge signal, receive a response signal from the vehicle, determine a distance between the mobile access device and the vehicle based on the response signal, determine a wait period based on the distance, wait a minimum period, where the minimum period is a minimum of (i) the wait period and (ii) an advertisement period or a predetermined ranging period, and subsequent to waiting the minimum period, transmit a second challenge signal to the vehicle to update the distance between the mobile access device and the vehicle.",
