This technology, as it seen today, may eventually replace existing systems: the 915 MHz DSRC in the U.S. and the 5.8 GHz DSRC in Europe.The development of this new technology is a response on the users and government organizations demand to establish the industry standard, system compatibility and improve road safety. Vehicular communications are becoming a reality, driven by navigation safety requirements and by the investments of car manufacturers and Public Transport Authorities. Safe navigation support through wireless car- to- car and car- to- curb communications has become an important priority for car manufacturers as well as Municipal Transportation Authorities and communications standards organizations. Standardization plays a very important role in the success of any potential large-scale deployment of a DSRC technology. A national deployment requires interoperability of equipment and systems coming from many different manufacturers, hardware / software certifications, compliance testing and security. A complete suite of standards is currently under development within IEEE and other standard organizations and these are expected to eventually migrate into ISO on a global scale. IEEE 802.11p addresses the physical layer and medium access control layer (MAC) called 802.11p module. The upper layers (network and others) of the communication stack are being developed within IEEE 1609 (Wave Management, Channel Management, & Resource Manager) and IEEE 1556 (DSRC Security) through the normal IEEE committee process. The vehicle aspects are being developed and evaluated through VSCC / CAMP (represents seven major automotive manufacturers) and SAE is developing the message set, data dictionary and application framework standards. 5.9 GHz DSRC is the emerging communication technology that offers standardized ITS products and benefits in national large-scale deployments. U.S. DOT and the automotive OEMs will be the strategic players making deployment decisions in the year 2008 timeframe (when the IEEE 802.11p is planned for ratification). 5.9 GHz DSRC systems provide a significant enhancement in communication capabilities over all previous ITS systems. DSRC will support multiple uses in vehicle / public safety and commercial applications that cannot be achieved today. DSRC is a cost-effective communications service, especially when compared with current cellular and satellite systems. The technology can be leveraged for Open Road ETC (electronic Toll Collection) and mobile 802.11 Wi-Fi deployments, creating nationally interoperable systems and networks. DSRC is the technology for the 2010 decade and beyond.
