Abstract: A beacon signal processing system of reducing wake-up frequency periodically receives a beacon signal from an access point. The beacon signal processing system, according to a data transfer type of a traffic indication message contained in the beacon signal, maintains a sleep mode or only wakes up part of modules of hardware and software necessary for communication for processing.

Abstract: A method for estimating reception time of beacon signals includes receiving a beacon from a transmitting device, checking the real-time clock (RTC) of a receiving device, checking a timing synchronization function (TSF) of the received beacon, and estimating a reception time of a next beacon according to the RTC, TSF and a period of the beacon.
