商品描述
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.
In easy to read chapters, with extensive references and links to get you to know all there is to know about IEEE 802.11ac right away, covering: IEEE 802.11ac, IEEE 802.11, 125 High Speed Mode, IEEE 802.11 (legacy mode), 802.11 non-standard equipment, IEEE 802.11a-1999, Wireless access point, Yota Egg, AEGIS SecureConnect, Announcement Traffic Indication Message, Arbitration inter-frame spacing, Block acknowledgement, IEEE 802.11b-1999, Beacon frame, CALM M5, Capwap, Carrier sense multiple access with collision avoidance, CCMP, Complementary code keying, DCF Interframe Space, Distributed coordination function, IEEE 802.11d-2001, Direct-sequence spread spectrum, Exposed node problem, Extended interframe space, IEEE 802.11e-2005, Frame aggregation, IEEE 802.11g-2003, Hidden node problem, IEEE 802.11h-2003, IEEE 802.11i-2004, Information Element, Inter-Access Point Protocol, IEEE 802.11j-2004, IEEE 802.11k-2008, Line-of-sight propagation, List of WLAN channels, Lorcon, MeshBox, IEEE 802.11n-2009, Nitro (wireless networking), IEEE 802.11p, PCF Interframe Space, Point coordination function, Power control, IEEE 802.11r-2008, Reduced Interframe Space, Received Channel Power Indicator, Received signal strength indication, Regdomain, Roofnet, IEEE 802.11 RTS/CTS, IEEE 802.11s, Short Interframe Space, Super G (wireless networking), Temporal Key Integrity Protocol, TU (Time Unit), IEEE 802.11u, IEEE 802.11v, IEEE 802.11w-2009, Wi-Fi operating system support, Wi-Fi Protected Access, Wired Equivalent Privacy, Wireless Distribution System, World-Wide Spectrum Efficiency, Xpress technology, IEEE 802.11y-2008.

商品描述(中文翻譯)
IEEE 802.11ac 是一個正在開發中的 802.11 無線標準,將提供高吞吐量的無線區域網路(WLAN),其頻率低於 6 GHz(即通常所稱的 5 GHz 頻段)。
理論上,這項規範將使多站點 WLAN 的吞吐量至少達到 1 吉比特每秒(1 Gbit/s),單一鏈路的最大吞吐量至少為 500 兆比特每秒(500 Mbit/s)。這是通過擴展 802.11n 所採用的空中介面概念來實現的:更寬的射頻帶寬(高達 160 MHz)、更多的 MIMO 空間流(高達 8)、多用戶 MIMO,以及高密度調變(高達 256 QAM)。
在 2011 年 1 月 20 日,IEEE 802.11 TGac 確認了初步技術規範草案 0.1。
標準的最終確定預計在 2012 年底,最終的 802.11 工作組批准則預計在 2013 年底。根據一項研究,預計到 2015 年,符合 802.11ac 規範的設備將變得普遍,全球預計將有約 10 億台。
