Multi-gigabit speed wireless communication requires a huge amount of bandwidth which is available in the license free 60 GHz band. Thus amongst others the Wireless Gigabit Alliance (WiGig) started in 2009 to develop a wireless communication technology operating in the 60 GHz band. The official Standard was published by IEEE in December 2012 as IEEE 802.11ad-2012. The WiGig Alliance was subsumed by the WiFi Alliance in March 2013.
WiGig® tri-band enabled devices, which operate in the 2.4, 5 and 60 GHz bands, deliver data transfer rates up to 7 Gbit/s. The 60 GHz signal cannot typically penetrate walls but can propagate off reflections from walls, ceilings, floors and objects using beamforming built into the WiGig® system.
