Abstract: The disclosed invention relates to a passive keyless entry receiver system having an application controller that is activated upon receipt of an entire payload of a data packet to determine if peak RSSI levels for a plurality of RSSI steps within the payload match an expected sequence of peak RSSI levels (i.e., if a fingerprint is genuine). The receiver system has a receiver that receives a wireless signal having a data packet with a plurality of power levels within a plurality of RSSI steps of the payload. The receiver system writes a plurality of peak RSSI levels to a plurality of RSSI peak payload registers that store the peak RSSI levels for RSSI steps of the payload. Once an entire payload of a data packet has been received an application controller determines if the peak payloads correspond to an expected sequence of power levels.

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.
