Claim 15:
16. A tire pressure monitoring system (TPMS), comprising:
a communication interface device configured to communicate with a target TPMS sensor module, the communication interface device comprising:
a radio frequency (RF) transceiver configured to;
generate at least one wake-up signal,
wherein the at least one wake-up signal is configured to cause a TPMS sensor module to transition from a low power state to an active state;

an antenna array configured to:
transmit, via an advertising channel, the at least one wake-up signal as a directional RF beam, wherein the advertising channel comprises a limited bandwidth relative to an RF data communication link; and

a processing circuit configured to:
monitor for a response signal in response to the antenna array transmitting the at least one wake-up signal,
record a power setting of a wake-up signal of the at least one wake-up signal to which the response signal is responsive, and
control the RF transceiver to transmit, via the RF data communication link a communication signal towards the target TPMS sensor module with the power setting of the wake-up signal to which the response signal is responsive.
