J,
I looked into Internet via a radio-transponder
modem. In mountainous areas it's great and can go out quite a few
miles. As I remember it, I think that six miles is about the outer
limit. The problems are:
- Trees & Foliage - they totally block the signal.
- Buildings - same as #1
- Smog, Fog, Rain & Smoke - they attenuate the signal.
- It's a line-of-sight system - it the antennas can't "see" each other,
there's no connect.
- In flat terrain (like Florida), with lots of tall trees, it's
tough to get a signal without a rather high antenna.
That said, if you can get a signal, it's a great system
and it provides high-speed, two-way service . A client of mine has
one at his office, and I've used it quite a bit. It's as
transparent as the cable system; and, I'd estimate it's as fast as cable -
perhaps a little faster. I've heard that you can get about 1.5 Mb/s.

I'm waiting for wireless that will reach out the same 5 kliks
from the
station as DSL. Sadly, where I live, cable and DSL only
arrived the
last year or two.
