Media access control apparatus and method in wireless local area network system

摘要: Disclosed is a media access control apparatus and method in wireless local area network (LAN) system, which improves the performance of by obtaining transmission opportunity based on information station (STA), received from an point (AP) contention-based distributed system such as IEEE 802.11 LAN system. In method, determines contention window (CW) value other stations accessing same idle state channel, so that inefficient CW be set Distributed Coordination Function (DCF) used 802.11. Accordingly, it possible to increase processing speed efficiency network.
