'''IEEE 802.11ad'''是對IEEE 802.11無線網路標準的修正，被開發為提供60 GHz頻率的多千兆無線系統（MGWS）標準，並且是[[WiGig]]網路的網路標準。因為它使用了V精密帶的毫米波（MMW）頻率，相比於其它常規的Wi-Fi系統，IEEE 802.11ad中通信範圍將相當有限（只有幾公尺遠，難以穿越障礙物/壁）。但是，高頻允許它使用更多的頻寬，這反過來又使得能夠以高達每秒數千兆字節的高數據速率傳輸數據，可以實現諸如通過無線網路傳輸未壓縮的UHD視頻之類的使用場景。<ref>{{cite web |url=http://www.rohde-schwarz.com/en/applications/802.11ad-wlan-at-60-ghz-application-note_56280-50625.html |title=802.11ad - WLAN at 60 GHz A Technology Introduction |website=White Paper by [[Rohde & Schwarz]] |format=PDF |date=2013-11-21 |access-date=2014-12-09 |archive-date=2015-09-10 |archive-url=https://web.archive.org/web/20150910171600/https://www.rohde-schwarz.com/en/applications/802.11ad-wlan-at-60-ghz-application-note_56280-50625.html |dead-url=no }}</ref>

儘管WiGig在2009年發布，並於2012年12月加入IEEE 802.11家族中，但它並不廣為人知。

在改版後，60GHz頻段覆蓋了57-71GHz的頻率。在IEEE 802.11ad中，該頻段細分成6個(以前為4個)不同的通道，每個通道都用2160MHz的空間並提供1760MHz的頻寬。<ref>{{Cite web |url=https://www.itu.int/dms_pub/itu-r/md/15/wp5a/c/R15-WP5A-C-0298!N17!MSW-E.docx |title=INTERNATIONAL TELECOMMUNICATION UNION Radiocommunication Study Groups Document 5A/TEMP/91(Rev.1) Annex 17 to Document 5A/298-E Annex 17 to Working Party 5A Chairman’s Report Working document toward a preliminary draft revision of RECOMMENDATION ITU-R M.2003-1 Multiple Gigabit Wireless Systems in frequencies around 60 GHz 18 November 2016 |accessdate=2020-11-08 |archive-date=2020-09-15 |archive-url=https://web.archive.org/web/20200915210259/https://www.itu.int/dms_pub/itu-r/md/15/wp5a/c/R15-WP5A-C-0298!N17!MSW-E.docx |dead-url=no }}</ref><ref>{{Cite web |url=http://www.bluwirelesstechnology.com/on-5g-millimetre-wave-technology-and-why-wireless-is-the-new-wired/ |title=On 5G millimetre wave technology and why wireless is the new wired |accessdate=2020-11-08 |archive-date=2018-12-07 |archive-url=https://web.archive.org/web/20181207051550/http://www.bluwirelesstechnology.com/on-5g-millimetre-wave-technology-and-why-wireless-is-the-new-wired/ |dead-url=no }}</ref>

IEEE 802.11ad的后继者为[[IEEE 802.11ay]]。
