2009년 9월 IEEE에서 802.11n 규격이 최종 승인된 바 있으며, 이로 인해 현재 11n 기반의 무선랜 보급이 더욱 본격화 되고 있다. 하지만 초고화질의 영상을 압축하지 않고 전송하려면 Gbps 이상의 전송 속도가 필요하며, 이를 위해 IEEE에서는 802.11n의 뒤를 이은 무선랜 규격인 802.11ac에 대한 표준을 개발하고 있다. IEEE 802.11ac는 다중 사용자 동시 접속 및 Gbps 급 이상의 고성능 지원에 초점을 맞추고 있으며, 802.11ac는 블루레이 및 압축되지 않은 초고화질 비디오 서비스를 실시간으로 제공할 수 있게 된다. 802.11ac규격은 현재 Draft 5.0까지 나와있는 상태로 표준 개발이 거의 완료되어 가고 있으며, 본 고에서는 이러한 IEEE 802.11ac 무선랜의 주요 기술 요소들에 대해 기술하고자 한다.
