(WIreless GIGabit) A short-range wireless technology from the Wireless Gigabit Alliance (WGA). It provides up to 7 Gbps of data transmission in the unlicensed 60 GHz band over a distance of approximately 10 meters. WiGig was designed to provide a wireless technology for gaming, backup, HD connections between A/V equipment and other high-speed applications.
WiGig offers an order of magnitude more bandwidth than Wi-Fi, but it throttles down to Wi-Fi speeds in noisy environments. At 60 GHz, the wavelength is only five millimeters and highly directional, and beamforming is used to continue operation when objects are in the way. However, if the signal is completely unobstructed, it can reach 20 meters and beyond.
The Wireless Gigabit Alliance was formed in May of 2009, and Version 1.0 of the specification was announced at year-end. For more information, visit www.wirelessgigabitalliance.org. See WirelessHD, beamforming and ISM band.
WiGig eliminates the wire routing and clutter when TVs are wall mounted and people use their computers as the source of movies and music. Using beamforming, the wireless router (white unit on wall) is transmitting to the laptop, which is streaming to the TV and smartphone.
