Dedicated short-range communications are one-way or two-way short- to medium-range wireless communication channels specifically designed for automotive use[1] and a corresponding set of protocols and standards.[2] In October 1999, the United States Federal Communications Commission (FCC) allocated in the USA 75MHz of spectrum in the 5.9GHz band for DSRC to be used by Intelligent Transportation Systems ITS.[3] Also, in Europe in August 2008 the European Telecommunications Standards Institute (ETSI) has allocated 30 MHz of spectrum in the 5.9GHz band for ITS.[4]
Currently its main use in Europe and Japan is in electronic toll collection.[5] DSRC systems in Europe, Japan and U.S. are not, at present, compatible.
Other possible applications are:
Other short range wireless protocols 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.
