Or you can get "radiomodems" - these are integrated modems/tranceivers
that work in the "unlicenced" 400MHz bands (these are in the UK and
most of Europe, probably elsewhere too). There are various of these which
operate at speeds of 9600 and above. Connectd to a couple of simple
aerials these will give more than the range you require, even over an
obstructed path.
Supplimentary:
Does anybody have a *cheap* source of Wavelan cards?
