This is a little off topic because it's more of a hardware question than a
software question.
Is there a system available that would let me have wireless connectivity
with a range of at least 1500 feet. There is one building in the way, but
it is otherwise open. I could even put the base antenna outside on the 5th
floor of my building. The mobile system will be in a tent (circus tent, to
be specific) most of the time.
The best I've been able to find offer about 1000 feet. Of course these
are all at least 10Mbps. For my application, I'd be happy with 56k. The
base system will most likely be running linux. The laptop will be running
whatever it takes to get the system operational. (I'll be using VNC, so
the OS of the laptop isn't that important.
Thanks
