Mobility promises us a future of connected driving: an increase in driving safety and road safety, autonomous driving, better traffic flow, less harm to the environment, and enhanced public and goods transportation. However, this future is one, from a technical standpoint, very hard to realize. The current transmission of data between vehicles is, currently, not fast enough to ensure safety amoungst autonomous vehicles.
The key to making this future a reality is the cooperative intelligent transportation system (C-ITS), which enables vehicles to exchange information with other vehicles and with traffic infrastructure in real time. This is known as V2X (Vehicle-to-everything) communication. Up to now, V2X communication has been based primarily on ITS-G5, a dedicated short-range communication (DSRC) standard. This means that the exchange of data between vehicles and roadside equipment happens through direct WLAN communication.
