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
Expected in 2021, 802.11ay is a proposed enhancement to 802.11ad that quadruples bandwidth and adds four streams of MIMO. 11ay also extends the distance to several hundred meters. See
