Dedicated Short Range Communications

From TheBestLinks.com

DSRC or Dedicated Short Range Communications is a short to medium range wireless protocol specifically designed for automotive use. It offers communication between the vehicle and roadsite equipment. This technology for ITS applications is working in the 5.9GHz band.

Currently its main use In Europe and Japan is in Electronic toll collection. DSRC systems in Europe and U.S. are not compatible.

Other possible applications are

• 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
• Highw-rail intersection warning

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