WiFi 802.22 Can Cover 12,000 Square Miles

tekgoblin writes "IEEE has just announced a new Wireless standard, 802.22, that can cover up to 12,000 square miles. The standard is actually for Wireless Regional Area Networks (or WRAN), which use the white spaces left in the TV frequency spectrum."

Simple maths:

12000 = pi r^2
3819.7186 ~= r^2
61.8039 ~= r

So, simple maths suggest that we're definitely not going to have reception if we're more than 62 miles away from the tower, and that doesn't take into account the curvature of the earth, the height of the tower, atmospheric distortions, etc.

but it does suggest the standard would allow for decent reception within a 30 mile radius. That ain't too bad.
