Please log in for more thread options I watched this video last night and found it fascinating The idea was to make each car in the US a combo wifi repeater..... so that each car sends and receives data but also relays other's data as well. This would create one huge shore to shore free wifi network such that the economic implications would be enormous. How feasible is all this? And can one easily create a mesh network in their home or even neighborhood? see the video http://www.ted.com/index.php/talks/robin_chase_on_zipcar_and_her_next_big_idea.html | |||||||||||||||||||

Totally not feasible. But that is to be expected from people that have no idea how wireless works. Let me guess...you're thinking that a wireless signal can go several miles from car to car. You're thinking a signal can be repeated hundreds of hops from car to car to car to car. > And can one easily create a mesh network

Not sure how hard it is to do with TCP/IP and related topology- discovery algorithms, but if one rearchitects a new protocol in parallel TCP/IP, I think it would be frighteningly simple, relatively speaking. -Le Chaud Lapin- | |||||||||||||||||||

I've been in a constant battle for the past two months with the decision- maker........I want the design to be a Layer3 routing device, but he wants it to be just a bridging device, because it's 'easier to get working' is his argument. I can see his point, because all of the companies we deal with that win bids for contracts, seem to have really no clue about how wireless really works. But still....... | |||||||||||||||||||
