I just remembered I've been talking to a guy (via Skype) in Clearwater, Fla. in the last hour and his setup to his ISP is WI-FI with an amplifier/power supply up the pole, covering a distance of about 20 miles. The setup was supplied and installed by his ISP. Regards Sid.

I'm not sure what part of the FCC regs that comes under. There is a reg that allows 1 watt ERP using frequency-hopping spread spectrum, and that's almost surely what this system is using. A 1 watt signal, especially if the receiver is using a directional (gain) antenna, would easily cover a 20 mile range, at line-of-sight. This is not the same sort of thing as is used for in-building routers. --doug, wa2say
