A 2012 IEEE Wi-Fi standard for short range transmission in the 57 to 71 GHz frequency range. The 802.11ad speed rating is 4.6 Gbps, which is more than three times the 802.11ac Wave 1 top speed of 1.3 Gbps (see
802.11ac). However, 11ac was designed as a next generation wireless LAN, whereas 11ad is more of a short range cable replacement (see
WiGig).
802.11ay
In 2021, 802.11ay is an enhancement to 802.11ad that quadrupled bandwidth and added four streams of MIMO. 11ay also extended the distance to several hundred meters. See
