IEEE 802.11ad is an amendment to the
IEEE 802.11
IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) technical standards, and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer commun ...

WiGig
WiGig, alternatively known as 60 GHz Wi-Fi, refers to a set of 60 GHz wireless network protocols. It includes the current IEEE 802.11ad standard and also the IEEE 802.11ay standard.

Extremely high frequency (EHF) is the International Telecommunication Union (ITU) designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). It lies between the super high frequency band and the ...
(mmW) frequency, the range of IEEE 802.11ad communication would be rather limited (just a few meters and difficult to pass through obstacles/walls) compared to other conventional Wi-Fi systems. However, the high frequency allows it to use more bandwidth (signal processing), bandwidth which in turn enables the transmission of data at high data rates up to multiple gigabit per second, gigabits per second, enabling usage scenarios like transmission of uncompressed graphics display resolution#High-definition, UHD video over the wireless network.
The WiGig standard is not too well known, although it was announced in 2009 and added to the IEEE 802.11 family in December 2012.
After revision, the 60 GHz band covers the frequency of 57 to 71 GHz. The frequency band is subdivided into 6 (previously 4) different channels in IEEE 802.11ad, each of them occupy 2160 MHz of space and provide 1760 MHz of bandwidth.
Some of these frequencies might not be available for the use of IEEE 802.11ad networks around the world (reserved for other purposes or requires licenses). Below is a list of available unlicensed spectrums for IEEE 802.11ad in different parts of the world:
