WiGig是一套60GHz無線網絡協議,[1]包括目前的IEEE 802.11ad標準和即將推出的IEEE 802.11ay標準。[2]

WiGig技術規格允許設備在不使用線纜的情況下進行數千兆的高速通信,這將使高性能的無線數據傳輸、顯示和音頻應用成為可能,並可作為過去的無線局域網技術的互補。WiGig三頻段設備可以在2.4GHz、5GHz和60GHz頻段上工作,最高可以以7Gbit/s的速度傳輸數據,幾乎與8個頻段的802.11ac一樣快。這相當於802.11n最高速率的11倍——但同時與現有的Wi-Fi設備保持兼容。60GHz的毫米波信號通常無法穿透牆壁,但信號可以被牆壁、天花板、地板和其他內建WiGig系統「波束成形」特性的物體反射。在漫遊離開主房間時,無線協議可以自動利用更低的頻段在低速下工作,比如2.4GHz和5GHz,這兩種頻段均可穿牆。[3][4]

WiGig這個名字來自於無線千兆聯盟,最初成立是為了促進IEEE 802.11ad的應用。現已併入Wi-Fi聯盟[5]
