I'm working on a fairly complex project which requires the use of an embedded system. The WRT54G seems to fit most of my needs for the project, and I have quite a few of them laying around. They're pretty much the cheapest mass-produced devices available that can run Linux. One of the requirements for the project is bi-directional communication over a span of about 30,000-80,000ft (line of sight). I know the router would require some extreme modification or some kind of external RF power booster to even come close to this range. The router will be moving at a fairly high rate of speed (60mph) so I can't use a directional antenna. I know it's probably just a pipe dream to get a WRT54G to work over these long distances. It could cut months off of my design time though, so it's worth a try. Does anyone know of a way that communication over extreme distances with a WRT54G might be possible? Thanks in advance!
