802.11ay is a next-generation Wi-Fi standard that defines a new physical layer for 802.11 networks to operate in the 60 GHz millimeter wave spectrum. It will be an extension to the existing 802.11ad, aimed to extend the throughput, range and use-cases including: indoor operation, out-door back-haul and short range communications.

This standard will increase the peak data rate to 100 Gb/s through supporting multiple independent data streams and higher channel bandwidth while ensuring backward compatibility and coexistence with IEEE 802.11ad. It will also extend transmission distance from the current 10 meters to as far as 300-500 meters.

Companies like Qualcomm have already released products based on a pre-standard version of IEEE 802.11ay and expect to begin trials of the integrated solution mid-2019.

This standard is still in development phase and the final specifications are expected to get approval in 2019.
