Hi guys, well, after reading through the backlog of spread spectrum stuff, I was surprised to read about the radio-network-on-a-board (Julieboard) article that someone posted. A couple of us here in Australia have been kicking around the idea of a cheap network, running via repeaters in _very_ small boxes tossed all around a city, which would be indestructible through sheer numbers (a la the arpanet). So: anyone got any ideas, schematics, information? The main idea is a huge number of small, low-power and CHEAP nodes which would handle through traffic which anyone with a radio modem could tap into, with the nodes disguised and placed in extremely hard to get to places (tops of telephone poles, buildings, on bridges and overpasses, etc). This would mean that it would cost an awful lot of money to remove each of these things, IF they could be found. Possible power sources: batteries (but they need to be changed) solar power (Australia leads the world in solar power technology, and I know people who know people). Near Field Interaction and EMF pickups (stick 'em near high-frequency power transmission lines). Something that convert heat to electrical energy or combinations of all of the above. The idea being that we would have an untraceable, unbreakable network. Sure, you may have an address (perhaps we could set it up as a FQDN domain?), but that address would not correspond to any actual physical location. And, it would be free, aside from the cost of the equipment. No more phone calls to pay for! I have no idea how this could be done across interstate or international distances, but I'm sure people might have ideas. Bounce signals off satellites (are those big shiny things from the 50's still about?); send stuff encrypted via the internet, etc etc. This could well mean that we would have a truly private network, with strong encryption and no centralised source of transmission (I mean, most of the internet traffic into and from Australia goes via a single link, so far as I know). Comments? Dwayne
