下一代WLAN标准IEEE 802.11ac物理层研究

Research on physical layer of next generation WLAN standard IEEE 802.11ac

无线本地接入网络支撑了移动业务的飞速增长,IEEE 802.11系列标准为WLAN的发展提供巨大的支持,文章简要阐述正在开发的新WLAN标准IEEE 802.11ac的物理层,如何使用更多带宽,更高阶调制和更多MIMO流来实现超过1 Gbps限制的高可靠数据速率,同时比较了802.11ac,802.11n和11a标准。

Wireless local access network has supported the rapid growth of mobile business, IEEE 802.11 series of standards provide great support for the development of WLAN, this paper briefly expounds the physical layer new WLAN standard IEEE 802.11 ac, which is in the development process, and expounds how to use more bandwidth, higher order modulation and more MIMO flow to achieve more than 1 Gbps of high reliable data rate, at the same time, 802.11ac, 802.11n and lla standard are compared.
