2. 802.11ad History
WiGig alliance promotes the IEEE ad Announced in May 2009
WiGig announced the release of its certification ready version 1.1 specs in June 2011
WiGig & Wi-Fi Alliance merged in March 2013
Wi-Fi Alliance announced the launch of its WiGig certification program in Oct 2016

3. 802.11ad Very High Throughput (VHT) main specs
802.11ad Operates at 60 GHz frequency
Use up to four 2.16 GHz channels. Over 8 GHz of Bandwidth
Each channel supports up to Gbps (using OFDM)
In Lower complexity single channel (SC) up to Gbps

4. 60 GHz Spectrum allocation

5. 60 GHz Spectrum allocation

6. 802.11ay Project Goals
Task Group ay is expected to develop an amendment that defines standardized modifications to both the IEEE physical layers (PHY) and the IEEE 802,11 medium access control layer (MAC) that enables at least one mode of operation capable of supporting a maximum throughput of at least 20 gigabits per second (measured at the MAC data service access point), while maintaining or improving the power efficiency per station. This amendment also defines operations for license-exempt bands above 45 GHz while ensuring backward compatibility and coexistence with legacy directional multi-gigabit stations (defined by IEEE ad-2012 amendment) operating in the same band.

7. 802.11ay Very High Throughput (VHT) main specs
802.11ay Operates at 60 GHz frequency
Link rate per stream Gbps
