coondoggie writes "The U.S. Department of Transportation said it will run a massive road test of cars, trucks and buses linked together via WiFi equipment in what the agency says will be the largest test of automated crash avoidance technology to date. The test will be conducted by the University of Michigan's Transportation Research Institute (UMTRI), and feature mostly volunteer participants whose vehicles have been outfitted with vehicle-to-vehicle and vehicle-to-infrastructure communication devices."

    3000 WiFi radios emiting together on how many channels and using what bandwidth ? Even if they drop to 1Mbps and use all 11 US 802.11 2.4Ghz channels, the collisions caused by ~270 devices on the same channell will make that network unuseable.

    What about the trolls with a WiFi jammer (like a microwave over with a screwdriver jammed in the door safety switch) ? Turn-it on and watch the pile-ups.

    Or will they use all channels in the 802.11n 5Ghz spectrum ?

No problem is so large it can't be fit in somewhere.

Working...
