"The longest link he could make with existing point-to-point WiFi connections was 400-500 feet; with the new Super WiFi gear in the TV band, he can reach a mile—and it's not a point-to-point signal." Something doesn't make sense here. This is the furthest they could get with point-to-point line of sight links, on towers. When I worked at a WISP, we routinely made longer PtP links—heck, even longer point-to-multipoint links. A mile should be easily doable with a clear line of sight. Using http://www.afar.net/rf-link-budget-calculator/ http://www.afar.net/rf-link-budget-calculator/ shows that a five-mile link should be no problem with 24dBi grid dishes (which are more or less the size of DirecTV, DISH, etc. dishes).
