2 miles is possible with good antennas. Do you have line of sight
between endpoints? If no line of sight, forget it. You can go
through a few branches here and there, but anything resembling a
forest is impossible. You will probably need two 24dBi dish antennas
and if you plan to run more than one computah, a pair of radios
capable of transparent bridging (DWL-900AP+, WAP54G, etc).
If you don't have line of sight, it might be possible to install a
midpoint wireless repeater. However, your thruput will be cut in half
and you'll need two additional antennas (can't be done at 2 miles with
an omni).
If you insist on going through the forest, 900MHz goes through much
easier than 2.4Ghz. Finding 900MHz bridges is rough. The access
point and client variety of 900MHz radios (WaveRider, Motorola
Canopy), will not talk between clients, so that's out. I've used a
few point to point 900MHz radios (FreeWave) but not current bridges.
See:
http://www.avalanwireless.com
for a possible pair of radios that might work through the trees.
935kbits/sec thruput. $1000 per pair with antennas. Ouch. If you go
this route, let me know as I also live in a (dense) forest and have
similar problems.
