- The present invention relates to a media access control (MAC) apparatus and method for guaranteeing quality-of-service in a wireless local area network (LAN). The MAC method comprises: extracting a user priority from a frame received from an upper layer and separately storing a voice frame and a general frame according to an access category (AC); independently performing backoff operations for the voice frame and the general frame; determining whether the backoff operations for the voice frame and the general frame have simultaneously ended; if the backoff operations have simultaneously ended, transmitting the voice frame having a higher priority first and performing the backoff operation for the general frame; and if the backoff operations have not simultaneously ended, transmitting a frame whose backoff operation ends.
