How secure is this connection? Does 802.11
provide security implicitly?

Thanks.

Oh, quite.

Here is my question: What equipment could I use to
do this? I found
some stuff on cisco's site, but it costs about
$8000. The speed does
not have to be supper fast, but I would like to
have something at
least the speed of ISDN.

Cisco BR340's - they're $900/each, and work well in
bridge mode. As
someone already stated, make sure you get some good
high-gain (and
narrow-beam directional - we use 10 degree yagi)
antenna's.

Is this plausible.  Is there any technology out
there that uses public
spectrum over a 6 mile distance ?

With line of sight, they claim they can go 9+ miles.
Of course, weather
does affect it - one of our spans tends to go down
when there's just the
right kind of heavy rain.

Theoretic speed is 11Mbit/sec - effective (real)
speed is about
6Mbit/sec. (YMMV, that's on a 1/2 mile span)
