The 802.11ay WiFi standard is an advancement to an earlier standard 802.11ad WiGig. Ratified in March 2021, this standard operates in the 60 and 70 GHz mmWave frequency bands, allowing for data transfer rates of up to 40 Gbps. Unlike many WiFi standards, 802.11ay utilises a technology known as beamforming, which focuses the WiFi signal in a specific direction towards the device in use, rather than broadcasting it in all directions. 802.11ay's high frequency band has a shorter range (typically up to 10 metres indoors and 100 metres outdoors) and is more easily obstructed by even minor barriers. As a result, it is best suited for applications within the same room or open spaces.
The standard can aggregate up to four 2160 MHz wide channels in 8x8 MIMO to achieve a theoretical max data rate of about 303 Gbps, although this is strictly a theoretical value.
