Microsoft's WhiteFi: Wi-Fi Using Whitespaces

Long-range, low-cost wireless Internet could soon be delivered using "whitespaces" - radio spectrum once reserved for use by TV stations. This week at ACM SIGCOMM 2009, a communications conference held in Barcelona, Spain, a computer network that uses "white spaces" in a fashion somewhat similar to Wi-Fi was outlined.

Networking over UHF white spaces is fundamentally different from conventional Wi-Fi, explains Ranveer Chandra of Microsoft Research, a main contributor to the paper. Their WhiteFi approach is a Wi-Fi like system constructed on top of UHF white spaces. WhiteFi incorporates a new adaptive spectrum assignment algorithm to handle spectrum variation and fragmentation in unused television channesl, and proposes a low overhead protocol to handle temporal variation.

definitely a cool concept. I will be looking forward to this for sure.
