Abstract

A method of communicating with a tire pressure monitoring system (TPMS) sensor module includes transmitting, by the TPMS sensor module, a TPMS signal that includes a sensor identifier of the TPMS sensor module; performing, by an interface device, an angle of arrival measurement on the TPMS signal to whether an angular direction thereof with respect to an antenna array of the interface device is within a predetermined angular window; and determining, by the interface device, whether or not to communicate with the TPMS sensor module including establishing communication with the TPMS sensor module on a condition that the angular direction is within the predetermined angular window and not establishing communication with the TPMS sensor module on a condition that the determined angular direction is not within the predetermined angular window.
