WiGig - 维基百科，自由的百科全书

WiGig是一套60GHz 无线网络协议，^[1]包括目前的IEEE 802.11ad标准和即将推出的IEEE 802.11ay标准。^[2]

WiGig技术规格允许设备在不使用线缆的情况下进行数千兆的高速通信，这将使高性能的无线数据传输、显示和音频应用成为可能，并可作为过去的无线局域网技术的互补。WiGig三频段设备可以在2.4GHz、5GHz和60GHz频段上工作，最高可以以7Gbit/s的速度传输数据，几乎与8个频段的802.11ac一样快。这相当于802.11n最高速率的11倍——但同时与现有的Wi-Fi设备保持兼容。60GHz的毫米波信号通常无法穿透墙壁，但信号可以被墙壁、天花板、地板和其他内建WiGig系统“波束成形”特性的物体反射。在漫游离开主房间时，无线协议可以自动利用更低的频段在低速下工作，比如2.4GHz和5GHz，这两种频段均可穿墙。^[3]^[4]

WiGig这个名字来自于无线千兆联盟，最初成立是为了促进IEEE 802.11ad的应用。现已并入Wi-Fi联盟。^[5]

歷史

2009年5月，成立无线千兆联盟以推廣IEEE 802.11ad標準。^[6]^[7]^[8]^[9]^[10]^[11]
2009年12月，推出了WiGig 1.0版技術規格。^[12]^[13]^[14]^[15]^[16]
2010年5月，WiGig聯盟發表其技術規範，並且開始進行其應用計劃，以及公佈和Wi-Fi联盟的聯絡協定，藉此合作延伸Wi-Fi技術。^[17]^[18]
2011年6月，WiGig聯盟公佈了可以進行認證的1.1版技術規格。^[17]
2012年12月，IEEE标准协会發表的IEEE 802.11ad-2012加入了IEEE 802.11家族。^[19]
2016年，Wi-Fi聯盟推出了WiGig產品的認證計畫。^[20]
第2代WiGig標準IEEE 802.11ay於2021年7月28日發表。^[21]
