商品描述

IEEE 802.11ac is a wireless standard of 802.11 currently under development which will provide high throughput Wireless Local Area Networks (WLAN) below 6 GHz (i.e., what is commonly known as the 5 GHz band).

Theoretically, this specification will enable multi-station WLAN throughput of at least 1 gigabit per second (1 Gbit/s) and a maximum single link throughput of at least 500 megabit per second (500 Mbit/s). This is accomplished by extending the air interface concepts embraced by 802.11n: wider RF bandwidth (up to 160 MHz), more MIMO spatial streams (up to 8), multi-user MIMO, and high-density modulation (up to 256 QAM).

On January 20, 2011, the Initial Technical Specification Draft 0.1 was confirmed by IEEE 802.11 TGac.

Standard finalization is anticipated in late 2012, with final 802.11 Working Group approval in late 2013. According to a study, devices with the 802.11ac specification are expected to become common by 2015 with an estimated 1 billion spread around the world.

This book is your ultimate resource for IEEE 802.11ac. Here you will find the most up-to-date information, analysis, background and everything you need to know.

商品描述(中文翻譯)

IEEE 802.11ac是目前正在開發中的無線標準，將在6 GHz以下（即通常稱為5 GHz頻段）提供高吞吐量的無線區域網絡（WLAN）。

理論上，該規範將實現至少1 Gbps的多站點WLAN吞吐量和至少500 Mbps的最大單鏈路徑吞吐量。這是通過擴展802.11n所採用的空中介面概念實現的：更寬的射頻帶寬（高達160 MHz），更多的MIMO空間流（高達8個），多用戶MIMO和高密度調變（高達256 QAM）。

2011年1月20日，IEEE 802.11 TGac確認了初始技術規範草案0.1。

預計標準最終定稿將在2012年底完成，並在2013年底獲得802.11工作組的最終批准。根據一項研究，預計到2015年，具有802.11ac規範的設備將在全球範圍內普及，估計達到10億台。
