Mega-Super WiFi 802.22 Can Cover 12,000 Square Miles

To put it in a nutshell, 802.22 was designed to run on a totally new spectrum which was made available when analog TVs were outlawed some years back in the US. For those who prefer more solid scientific figures, the 802.22 spectrum will work in ranges from 54MHz to 698MHz, where such frequencies are the perfect vehicle for long distance transmissions.

Imagine sending out 22 Mbps of data within a 62 mile radius from a sole base station – that would certainly bring Wi-Fi connectivity to even the most rural areas around the country. _Ubergizmo
IEEE has created a new 802.22 WiFi standard to take advantage of the FCC "Super WiFi" classification.
IEEE, the world’s largest professional association advancing technology for humanity, today announced that it has published the IEEE 802.22TM standard. IEEE 802.22 systems will provide broadband access to wide regional areas around the world and bring reliable and secure high-speed communications to under-served and un-served communities.

This new standard for Wireless Regional Area Networks (WRANs) 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. Each 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.

IEEE 802.22 incorporates advanced cognitive radio capabilities including dynamic spectrum access, incumbent database access, accurate geolocation techniques, spectrum sensing, regulatory domain dependent policies, spectrum etiquette, and coexistence for optimal use of the available spectrum.

The IEEE 802.22 Working Group started its work following the Notice of Inquiry issued by the United States Federal Communications Commission on unlicensed operation in the TV broadcast bands. _IEEE Press Release via Tekgoblin
More on Super WiFi:
Super Wi-Fi is inching closer to reality, and now the IEEE, the standards organization responsible for all things Wi-Fi, has published the IEEE 802.22standard.

This new wireless networking standard promises speeds up to 22Mbps to devices as far as 100-kilometers (roughly 62-miles) away from the nearest transmitter. This new band of Wi-Fi on steroids comes through the patch of "white space" frequencies that were previously used to analog television broadcasts.

There’s no word on when and which regions of the United States will be the first to get in on this super Wi-Fi. Houston is currently the only access point for a white space Wi-Fi, which comes courtesy of Rice University researchers. Super Wi-Fi has been slow in coming since the FCC originally approved it back in September 2010. _PCWorld
Similar technologies can create dynamic wide range data networks on the open seas, to improve safety and expand exchange for large fleets of working seasteads. New colonies built across the Arctic and Antarctic could likewise use this type of wide range networking, to coordinate activities, weather warnings, etc.
