5 GHz Vehicle-to-Vehicle Communications

Car-to-car communications protocols have passed field testing trials  The frequency range 5.875 to 5.925 GHz is being used for Cooperative Transport Systems using modified WiFi technology.

The evaluation of a large Car2x communications field test proves that the technology is now ready for mass deployment, say its promoters. The simTD (Safe Intelligent Mobility - Test Field Deutschland) test involved 123 vehicles - including cars and motorbikes - in real-world traffic. Results indicate that the number of accidents could be significantly reduced if the technology were widely deployed.
