Dedicated short-range communications are one-way or two-way short-range to medium-range wireless communication channels specifically designed for automotive use[1] and a corresponding set of protocols and standards.

History[edit]

In October 1999, the United States Federal Communications Commission (FCC) allocated 75 MHz of spectrum in the 5.9 GHz band to be used by intelligent transportation systems (ITS).[2] In August 2008, the European Telecommunications Standards Institute (ETSI) allocated 30 MHz of spectrum in the 5.9 GHz band for ITS.[3]

By 2003, it was used in Europe and Japan in electronic toll collection.[4] DSRC systems in Europe, Japan and U.S. are not compatible and include some very significant variations (5.8 GHz, 5.9 GHz or even infrared, different baud rates, and different protocols).[citation needed]

Singapore's Electronic Road Pricing scheme uses DSRC technology for road use measurement. [5]

Other possible applications were:

  • Emergency warning system for vehicles
  • Cooperative Adaptive Cruise Control
  • Cooperative Forward Collision Warning
  • Intersection collision avoidance
  • Approaching emergency vehicle warning (Blue Waves)
  • Vehicle safety inspection
  • Transit or emergency vehicle signal priority
  • Electronic parking payments
  • Commercial vehicle clearance and safety inspections
  • In-vehicle signing
  • Rollover warning
  • Probe data collection
  • Highway-rail intersection warning
  • Electronic toll collection

Other short-range wireless protocols are IEEE 802.11, Bluetooth and CALM.

Standardization[edit]

The European standardization organisation European Committee for Standardization (CEN), sometimes in co-operation with the International Organization for Standardization (ISO) developed some DSRC standards:

  • EN 12253:2004 Dedicated Short-Range Communication – Physical layer using microwave at 5.8 GHz (review)
  • EN 12795:2002 Dedicated Short-Range Communication (DSRC) – DSRC Data link layer: Medium Access and Logical Link Control (review)
  • EN 12834:2002 Dedicated Short-Range Communication – Application layer (review)
  • EN 13372:2004 Dedicated Short-Range Communication (DSRC) – DSRC profiles for RTTT applications (review)
  • EN ISO 14906:2004 Electronic Fee Collection – Application interface

Each standard addresses different layers in the OSI model communication stack.
