It seems that Dash-like devices that rely on plain old GPRS for two-way vehicle communications could one day be a bit redundant in Europe, as the European Commission has just set aside a slice of spectrum that's intended specifically to let vehicles communicate with each other. As with the Dash and other similar devices, the idea here is to give drivers a heads up about traffic jams and other potential hazards, with real-time data provided by other drivers ensuring all that info is as up to date as possible. The system, which will make use of 30MHz of spectrum in the 5.9GHz band, will also apparently allow roadside transmitters to send vital info to vehicles passing by, although exactly when that might happen is, of course, a bit unclear at the moment.
