If you've got doubts about the distance, have a look at this network.  The
long haul links use Tsunami equipment.  There's all sorts of stats and
whatnot on the site as well, correlated with weather data, etc.

The main site is:

The long-haul links go up to 45mb/s, and while I can't quite find it, I
believe there may be a few 155mb/s links.

if you have line of sight you can look into microwave equipment. the
spectrum(18,23,38 ghz) is generally liscensed so there are regulatory
hurdles to jump through unless you're down in the 5725-5825mhz unliscensed
band...

These days this mostly makes sense if there's no physical infrastructure
in place.

take a look at:

for radio's for that sort of thing.

hey all,

we've got a client that wants some crazy stuff, and i need either
suggestions or confirmation that this is impossible/too expensive.

client needs 45Mbps pushed over 20 miles... and he wants it wireless. the
kicker is that they don't want a T3 because it is "too expensive" and it
would take too long to get installed. it doesn't need to be constant, but he
wants to move of 2.5GB within 45 minutes. this is in the chicago area, if
that helps any. so, i don't know, satellite?
