enables the transmission of data at high data rates up to multiple gigabits per second, enabling usage scenarios like transmission of uncompressed UHD video over the wireless network. The WiGig standard was announced in 2009 and added to the IEEE 802.11 family in December 2012. After revision, the 60 GHz band is 57 to 71 GHz. The 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:
