Abstract:
A wireless communication system and method. The system includes processing circuitry, and a transceiver coupled to the processing circuitry. The processing circuitry includes logic to generate a wake-up packet addressed to another wireless communication system and including a legacy preamble portion and a wake-up portion, the legacy preamble portion modulated according to a first modulation rate. The wake-up portion is modulated according to a second modulation rate lower than the first modulation rate and includes information to wake-up the other wireless communication system. The transceiver system is to transmit the legacy preamble using a first transmit power level, and to transmit the wake-up portion using a second transmit power level higher than the first transmit power level by a predetermined amount such that an average received power of the wake-up portion is equal to an average received power of the legacy portion at the third-party station.
