1997년에 IEEE 802.11 WG에서 1~2Mbps급의 전송속도를 가지는 근거리 무선 LAN에 대한 규격을 시작으로, 최근 100Mbps 이상 고속의 데이터 전송속도를 지원하는 규격에 이르기까지 무선 LAN에 대한 기술이 지속적으로 발전되고 있다. 최근 무선통신 분야에서는 다양한 멀티미디어 데이터를 고속으로 전송하는 응용서비스가 증가하고 있으며, 이러한 서비스를 지원할 수 있는 무선 QoS MAC 기술이 IEEE 802.11e에서 표준화되었다. 본 고에서는 무선 LAN 관련 국제 표준화기구인 IEEE 802.11 WG에서 진행되고 있는 표준화 내용 중에서 802.11e에서 표준화한 QoS MAC 기술을 중심으로 MAC 기술 및 관련 표준화 동향에 대하여 살펴보고자 한다.
