A method and an apparatus for filtering a wireless signal by parsing a wireless signal transmitted from a surrounding wireless terminal so as to extract channel information of the surrounding wireless terminal in a MAC frame and performing adaptive filtering on the wireless signal.

Method and apparatus for detection adjacent channel interference signal using channel information in mac frame

A control method of beacon receiving time performed in a station that includes a receiving stage, receiving a first beacon n times from an access point (AP), and n is a natural number greater than or equal to 1; a computing stage, computing a first waiting time of a difference between a station wake-up time for receiving the first beacon and a receiving time of the first beacon every time of the n times of receiving; a deriving stage, deriving a representative value out of the n first waiting times; and a setting stage, setting a sum of a first beacon interval and the representative value of the first waiting times as a first wake-up interval of the station.

Control method of beacon receiving time and station using the method

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.

Beacon signal processing system and filtering method of reducing wake-up frequency

A terminal includes a first storage, which is kept turned on in a sleep mode, and is utilized to store a first packet transmitted with a server, a second storage which is utilized to store data required for the terminal in a wake-up mode, a central processing unit which is utilized to generated a second packet according the first packet and send the first packet to a access point in the sleep mode, and a communication unit which is connected to the access point and is utilized to transmit the second packet according to control of the central processing unit.

Terminal and operating method thereof

A beacon signal minimization method and a beacon signal processing system utilizing a changed beacon element periodically receives a beacon signal from an access point and maintains network connectivity in a sleep mode, or only wakes up modules of hardware and software necessary for communication, by comparing whether an information element contained in the beacon signal is different from information stored in advance.

Beacon signal processing system

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.
