DSRC systems in Europe, Japan and U.S. Dedicated short-range communications (DSRC) are one-way or two-way short- to medium-range wireless communication
Dedicated short-range communications channels specifically designed for automotive use The decision to use the spectrum in the 5GHz range is due to its
communications spectral environment and propagation characteristics, which are suited for vehicular Dedicated short-range communications environments - waves propagating in this spectrum can offer high data rate communications for long distances (up to 1000 meters) with low weather dependence.
Currently its main
IEEE Communications Society use in Europe and Japan is in electronic toll collection.
are not, at present, compatible.
Other possible applications are:
Other short range wireless protocols Dedicated short-range communications are IEEE 802.11, Bluetooth and CALM.
In the European standardization organisation CEN, sometimes in co-operation with the International Organization for Standardization (ISO) the following DSRC standards have been developed:
Each standard addresses different layers in the OSI model communication stack.
