IEEE 802.22 Super WiFi standard available for free download
Standard specifies the use of broadcast TV's whitespace to establish wireless regional area networks (WRANs) that transmit as much as 22 Mbits/sec at distances up to 100 kilometers.
As part of its IEEE Get Program, the Institute of Electrical and Electronics Engineers has made its 802.22 specifications, dubbed the "Super WiFi" standard, available for free download.
Published in July 2011, the Super WiFi standard is officially titled IEEE 802.22-2011 Standard for Wireless Regional Area Networks in TV Whitespaces. When announcing the standard's publication, the IEEE explained it "takes advantage of the favorable transmission characteristics of the VHF and UHF TV bands to provide broadband wireless access over a large area up to 100 km from the transmitter." The IEEE added that each wireless regional area network (WRAN) "will deliver up to 22 Mbps per channel without interfering with reception of existing TV broadcast stations, using the so-called white spaces between the occupied TV channels. This technology is especially useful for serving less densely populated areas, such as rural areas, and developing countries where most vacant TV channels can be found."
The project authorization request for 802.22 was submitted in October 2009 and approved in December of that year. The request described the need for the project as follows: "There is a large, untapped market for broadband wireless access in rural and other unserved/underserved areas where wired infrastructure cannot be economically deployed. Products based on this standard will be able to serve those markets and increase the efficiency of spectrum utilization in spectrum currently allocated to, but unused for, the TV broadcast service."
