y IEEE 802.11y-2008 extended operation of 802.11a to the licensed 3.7 GHz band. Increased power limits allow a range up to 5000m. As of 2009[update], it is only being licensed in the United States by the FCC.
IEEE 802.11y-2008 is an amendment to the IEEE 802.11-2007 standard that enables high powered Wi-Fi equipment to operate on a co-primary basis in the 3650 to 3700 MHz band in the United States, except when near a grandfathered satellite earth station.[1] It was approved for publication by the IEEE on September 26, 2008.
Sep 26 2008: P802.11y is approved as a new standard during the IEEE-SA Standards Board's meeting that took place on this date. The final draft document for amendment y is forwarded to the IEEE's Standards Publications Department in preparation for printing. This Standard took about 31 "participant weeks" over 2.5 years to draft and ballot 74 pages and resolve 1638 comments for this amendment to the 802.11 Base Standard.
While the scope of 802.11y was limited to operation in the US 3650-3700 MHz band in the US, care was taken so that, if the light licensing concept was well received, it would not be necessary to start the 3+ year task group process in order for 802.11y devices to operate in other countries or in other frequency bands. As a result, lightly licensed 802.11 devices will be able to operate in any 5, 10, or 20 MHz channel that regulators make available by simply adding entries to the country and regulatory information tables in Annex I and J of 802.11.
