WiGig or 802.11ad: Compatible Wireless Wi-Fi Transmission Protocol


WiGig is the trademark for Wireless Gigabit Alliance, an alliance formed to develop and promote the wireless Wi-Fi transmission protocol 802.11ad. Like WirelessHD, this protocol is operating over the unlicensed 60 GHZ frequency band. The WiGig specification allows devices to communicate without wires at multi-gigabit speeds. Theoretically a typical WiGig device can deliver data transfer rates up to 7 Gbit/s with whole 7 GHZ bandwidth.It is approximately as fast as an 8 antenna 802.11ac transmissions. If divided to four 2.16-GHz wide channels, one single-channel can archive a speed up to 4.6 Gbit/s.

WiGig Alliance has merged with the Wi-Fi Alliance and its wireless HDMI standard is defined in the IEEE 802.11ad. This means WiGig get a full compatibility with existing Wi-Fi IEEE protocols. Most consumers are well aware of IEEE protocols because they have experience with all the earlier ones, namely IEEE 802.11a, b, g, and n. The 11b/g/n standards operate in the 2.4-GHz band. The 11a/ac/n standards operate in the 5-GHz band, and the 802.11ad standard targets the 60-GHz band. The WiGig tri-band Wi-Fi chips can switch seamlessly from one standard to another in one of the three Wi-Fi bands: 2.4, 5, or 60 GHz
