The Institute of Electrical and Electronics Engineers Inc. (IEEE) approved the second of four standards for a new breed of wireless communications that will let motor vehicles interact with roadside systems to access safety information and travel-related services, even at high speed.
The newly approved standard, IEEE 1609.1 - Trial-Use Standard for Wireless Access in Vehicular Environments (WAVE) Resource Manager, provides the resource manager for this wireless system.
This service multiplexes the communications of multiple remote applications, each of which can interact with radio units in many vehicles at once.
IEEE 1609.1 describes the flow of the command-response interchange between the multiple remote applications and the resource manager and extending to vehicle radio units.
The services and interfaces it specifies include protective mechanisms for security and privacy. The resource manager is intended to enable a wide range of applications supported by vehicle units of the lowest possible cost.
WAVE communication technology (also known as Dedicated Short Range Communication or DSRC) is a short-to-medium-range wireless radio link that will allow passenger vehicles in the U.S. to speak with roadside stations and other WAVE-equipped vehicles.
In addition to giving drivers information to help them reach their destinations safely and efficiently, it will also allow for such applications as Internet access, arranging for lodging and ordering goods and services while in transit. WAVE radio operates in the 5.9 GHz band as authorized by the U.S. Federal Communication Commission (FCC) for Intelligent Transportation Systems (ITS).
The other WAVE standard was approved in June 2006. IEEE 1609.2 - Trial-Use Standard for Wireless Access in Vehicular Environments - Security Services for Applications and Management Messages, covers methods to make WAVE messages secure and the administrative procedures for core security functions. It provides mechanisms to protect messages against eavesdropping, spoofing, alteration and other attacks.
The auto industry is currently developing ways to add this technology to cars, and wireless manufacturers have begun to build prototype WAVE radios. Regional highway testing for WAVE radio will begin in the near future. In addition to auto and equipment manufacturers, stakeholders in this technology include state and local transportation departments, toll authorities, public safety organizations and public transit officials.
IEEE 1609 standards provide a radio communication component to support the U.S. Department of Transportation (DOT) Vehicle-Infrastructure Initiative and Intelligent Transportation System program. Two more IEEE WAVE-related standards are underway - IEEE P1609.3 and IEEE P1609.4.
IEEE 1609.1 is sponsored by the Intelligent Transportation Systems Committee of the IEEE Vehicular Technology Society.
