Abstract: PURPOSE: A dispersed AP(Access Point) selection method through the traffic recognition in radio environment using multiple transmission rate based on a beacon frame is provided to broadcast a beacon frame, thereby selecting AP which can be expected the highest treatment amount among a plurality of APs neighboring to a client. CONSTITUTION: An AP measures a retry field value of incoming packet transmitted from each client within a BBS(Basic Service Set)(S410). The AP measures a goodput during constant time. The AP uses the retry field value and the goodput to calculate throughput/client per client, and idle probability(S420). The AP transmits a frame including the retryratio, the treatment amount per client, and a frame including the idle probability to at least one client within a BBS(S430).
