A tire pressure monitoring system (TPMS) includes a communication interface device configured to communicate with a target TPMS sensor module. The communication interface device include a radio frequency (RF) transceiver configured to generate at least one wake-up signal; an antenna array configured to transmit each wake-up signal as a directional RF beam; a processing circuit configured to monitor for a response signal in response to the antenna array transmitting the at least one wake-up signal; and a power amplifier configured to set a power of each wake-up signal according to an adjustable power setting such that the power of each subsequent wake-up signal is increased in discrete steps until the response signal is received by the RF transceiver.
