New IEEE 802.22 Wi-Fi Standard Promises Better Broadband For Rural Communities And Emerging Nations

A new standard for Wi-Fi published recently by the IEEE Standards Association could put an end to broadband dead spots in rural areas and countries without mature Internet infrastructure.

802.22 Wi-Fi, which has a range of over 100 kilometres and utilises the unused VHF and UHF frequencies between TV channels, will be used for Wireless Regional Area Networks (WRAN) in places where users are too far from a traditional exchange using copper wire, or where expensive iptic fibre installations aren't an option because of cost.

The technology, according to thinq_, uses dynamic spectrum access, incumbent database access, accurate geolocation techniques, spectrum sensing, regulatory domain dependent policies, spectrum etiquette, and coexistence to make sure broadband streams do not interfere with TV signals.
