据说是非draft的最终版. Abstract: This amendment defines modifications to both the IEEE 802.11 physical layer (PHY) and the IEEE 802.11 medium access control (MAC) sublayer so that modes of operation can be enabled that are capable of much higher throughputs
802.11（WLAN）技术作为成熟而广泛应用的无线接入技术，已经广泛地应用于家庭、企业等。据统计，仅2008年一年，全球销售了3亿8千多万颗WLAN芯片。尽管802.11a/g技术已经将物理层吞吐提高到了54Mbps，但是随着YouTube、无线家庭媒体网关、企业VoIP Over WLAN等应用对WLAN技术提出了越来越高的带宽要求，传统技术802.11a/g已经无法支撑。用户需求呼唤着全新一代WLAN接入技术。
IEEE standard for information technology This amendment specifies enhancements to IEEE 802.11 physical layer (PHY) and medium access control (MAC) sublayer to provide modes of operation with useful data rates substantially higher than those previous
802.11n’s appeal can be summed up in one word—speed. In the stone ages of 1 Mbps and 2 Mbps wireless LANs, the most charitable thing that one could say about the technology was that it was faster than DSL. With the benefit of a decade of development
