IEEE Begins New WAVE Transportation Standard Work (1/17)
Wednesday, January 17, 2007 | Comments
The IEEE approved the start of the fifth member of its body of WAVE radio standards, which will integrate the other WAVE standards so they work well together. The standards will let motor vehicles interact with other autos and with roadside systems to access safety information and travel-related services. The new standards development project, IEEE P1609.0, "Wireless Access in Vehicular Environments (WAVE) - Architecture for New Standard Vehicular Technology/Intelligent Transportation Systems," will be an overview document offering general descriptions for the messaging multi-channel WAVE devices needed when communicating in mobile vehicular environments. WAVE technology, also called Dedicated Short Range Communications (DSRC), is a short- to medium-range radio link that will allow U.S. passenger vehicles to communicate with roadside stations and other WAVE-equipped vehicles. It operates at 5.9 GHz as authorized by the FCC for intelligent transportation systems (ITS) and will complement cell phones by offering high data rates, IEEE said. Its upper layer protocols and services requirements are described by IEEE 1609 standards that build on IEEE 802.11 and P802.11p LAN standards. In addition to giving drivers information to safely and efficiently help them reach their destinations, WAVE radio will open a new generation of transportation applications, such as Internet access, arranging for lodging, and ordering goods and services in transit. IEEE said testing of a prototype WAVE radio system is under way in California. As well as auto and wireless equipment manufacturers, stakeholders in WAVE technology include state and local transportation departments, toll authorities, public-safety organizations and public-transit organizations. IEEE 1609 standards are trial-use standards scheduled to be updated based on experience and should become full-use standards in 2008 or 2009. Three other IEEE 1609 standards have been approved, and a fourth standard is under development.
