Re: transparent internet via radio

[Andrew Bates <abates@omeganetserv.com>]

Adrien,

You should investigate using wireless ethernet (802.11b).  Several of 
the 802.11b channels are in the Amateur spectrum.  Also, the equipment 
is widely available and quite afordable.  By utilizing yagi or parabolic 
antennas and good transcievers, you should be able to achieve a 15 mile 
distance while maintaining at least 1mbps or better.

Of course, one of the drawbacks is that 802.11b requires nearly a 
line-of-site path as 2ghz signals are easily reflected or absorbed by 
obstructions.

Hope this helps!
