What is DSRC (Dedicated short‐range communications)?

Dedicated short-range communications (DSRC) are one-way or two-way short-range to medium-range wireless communication channels explicitly intended for automotive utilization and a corresponding set of protocols and standards. DSRC gives a profoundly secure communication channel. DSRC works in the 5.9 GHz band giving low latency data exchange among vehicles and the framework. In 2004, the FCC devoted a bandwidth of 75 MHz for DSRC in the 5.9 GHz band.
