An IEEE Wi-Fi standard for short range transmission in the 57 to 71 GHz frequency range. Introduced in 2012, the 802.11ad speed rating is 4.6 Gbps, which is more than three times 802.11ac's 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
