There are some practical problems with the current WiFi technology. There are only 3 non-overlapping channels. There is a lot of potential interference - microwave ovens, cordless telephones, etc. It needs line-of-sight clearance from the client radio to the access point.
But when it works, wireless is great. I'm on a 2.5 mile WiFi link right now. But fiber is better - if you can get it.
"My point is how much coverage is fiber? And cost IS an issue. especially if Bush wants to bridge this "divide" with Fed money."
The cost of the fiber is trivial compared to the economic harm our crumbling, 100-year-old telephone system is causing.
