IEEE 802.11ad (also referred to by its subject ''directional multi-gigabit'', i.e., DMG) is an amendment to the
IEEE 802.11 wireless networking standard, developed to provide a Multiple Gigabit Wireless System (MGWS) standard in the 60 GHz band, and is a networking standard for
WiGig networks. Because it uses the
V band of the
millimeter wave (mmW) band, 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
Wi-Fi () is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for Wireless LAN, local area networking of devices and Internet access, allowing nearby digital devices to exchange data by ...
systems. However, its great
bandwidth 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:
