  • Published : 2011.10.31

Abstract

가정, 기업, 오피스 및 공공장소에서의 폭넓은 무선 데이터 서비스 사용에 따라 거대한 영향력과 시장성을 갖게 될 차세대 WLAN 기술 및 시스템에 대한 관심이 더욱 높아지고 있다. 본고에서는 IEEE 802.11의 표준 기술 및 표준화 진행 중인 개발 기술들에 대해 살펴본다. WLAN을 기반으로 하는 IEEE 802.11의 간략한 history와 배경뿐만 아니라, IEEE 802.11a/b/g/n/ac/ad 등의 기술적인 부분을 요약하여 개발 현황을 알아보고, 확보된 기술을 통한 시장 상태와 차세대 기술개발을 통한 시장동향을 논의한다.
