WiGig

(WIreless GIGabit) A short-range wireless technology from the Wireless Gigabit Alliance (WGA). Using the unlicensed 60 GHz band, WiGig transmits 1080p HD video from a data source to a TV within approximately 30 feet. Supporting a 7 Gbps data rate, WiGig also provides a wireless technology for gaming, backup and other high-speed data transmission requirements.

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 five-millimeter wavelength is highly directional, and beamforming is used to continue operation when objects get in the way. However, if the signal has no obstruction, it can upwards of 60 feet.

Founded in 2009, the Wireless Gigabit Alliance announced Version 1.0 of the specification at year-end. For more information, visit www.wirelessgigabitalliance.org. See wireless USB, WirelessHD, WHDI, beamforming and ISM band.


No More Wires
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.

Wi-Gig will be aimed on short-range, high-speed data transfer as well as constant high-throughput applications, such as home automation and the Internet Of Things/ smart home products.
Samsung stated that the technology will let users with Wi-Gig equipped devices transfer a 1 GB movie between devices in less than 3 seconds, and uncompressed HD videos can be streamed from mobile devices to TVs in real time without postponement Samsung intends to commercialize the technology as early as next year in a variety of devices along with other chipset makers for example Qualcomm.
The Wi-Gig standard had earlier struggled to gain acceptance in the industry owing to the difficulty of commercializing the underlying technology because of the limitations present in using such a high radio frequency for high-speed data transfer, for example requiring line of sight for best performance, and specialized antenna design that would have earlier needed expensive packaging and chipset/antenna designs.
The partnership between Wi-Gig vendor Wilocity and Wi-Fi vendor Qualcomm Atheros to produce tri-band solutions is starting to bear fruit as Dell were the first to announce an ultrabook product with WiGig / 802.
