Message Text: The IEEE Standards Association (IEEE-SA) Standards Board has approved the IEEE 802.11ad-2012 amendment to provide data rates up to 7 Gbps, more than 10 times the maximum speed previously enabled within the IEEE 802.11 standard.

With the improvements introduced in IEEE 802.11ad, this amendment is a complement to the existing IEEE 802.11 standard, acting as the foundation for tri-band networking, wireless docking, wired equivalent data transfer rates and uncompressed streaming video.

IEEE 802.11 defines the technology for the wireless LAN (WLAN) products. IEEE 802.11-based products are often branded as "WiFi" in the market.

The IEEE 802.11ad specification adds a "fast session transfer" feature, which enables wireless devices to seamlessly transition between the 60 GHz frequency band and the legacy 2.4 GHz and 5 GHz bands. The ability to move between the bands ensures that computing devices are always "best connected," enabling them to operate with optimal performance and range criteria.

"IEEE 802.11 is undergoing a continuous process of refinement and innovation to address the evolving needs of the marketplace, and there is no better proof of that fact than IEEE 802.11ad," said Bruce Kraemer, chair of the IEEE 802.11 Wireless LAN Working Group. "By migrating up to the next ISM band (60 GHz), we break ground on new spectrum for IEEE 802.11, enable an order of magnitude improvement in performance and enable usages that have never before been possible with existing IEEE 802.11 ? namely wireless docking and streaming video."

Through the mprovements in spectral reuse at 60 GHz and an efficient beam forming technology, IEEE 802.11ad enables great improvements in capacity, allowing many users in a dense deployment to all maintain top-speed performance, without interfering with each other.
