A wireless communication system capable of saving time for mutual data communication in a sniff mode. The wireless communication system has: a master apparatus for calculating a sniff parameter including a time of a sniff period capable of performing the communication by allowing a corresponding device to commonly have the time in the sniff mode, when a communication mode for a mutual data communication by a user is selected to be operated in the sniff mode; and a sniff slave apparatus for performing the mutual data communication with the master apparatus by commonly having a corresponding time calculated in accordance with the sniff parameter. At this time, the sniff parameter includes at least one among a cyclic information, an allocated time information of the sniff period, and a start time information in which the master apparatus communicates with the sniff slave apparatus operated in the sniff mode. Moreover, the master apparatus performs communication scheduling for data communication of the sniff slave apparatus, when the sniff parameter is calculated. The time needed for the mutual data communication during the allocated time of the sniff period is saved, since the master apparatus sets up the time for communicating with the sniff slave apparatus, allows the sniff slave apparatus to commonly have the set-up time, and controls the slave apparatus to communicate with the master apparatus.
