IEEE Publishes the 802.11p Amendment to Extend the Base IEEE 802.11 WLAN Specification for Wireless Access in Vehicular Environments

The IEEE today announced that it has published the IEEE 802.11p- 2010, Standard for Information Technology-Telecommunications and Information Exchange between systems-Local and Metropolitan networks-Specific requirements-Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) specifications: Wireless Access in Vehicular Environments.

This amendment defines mechanisms that allow IEEE 802.11™ technology to be used in very high speed, rapidly changing, radio environments encountered by cars and trucks on highways. IEEE 802.11p™ defines enhancements to the physical layer to deal with the extreme Doppler shifts and rapidly changing multipath conditions encountered as vehicles are communicating with each other or to the roadside at speeds of up to 200 kph. It also defines the MAC layer changes required to satisfy the needs of entering a new communication zone and being able to quickly establish a link and exchange multiple packets of data within less than 100 ms total elapsed time from entering to exiting that zone. Further MAC changes are designed to support other higher layer protocols that are designed for the vehicular environment, such as the set of IEEE 1609™ standards for Wireless Access in Vehicular Environments

About IEEE 802

The IEEE 802® LAN/MAN Standards Committee develops LAN and metropolitan area network (MAN) standards. The most widely used standards are for the Ethernet family, Token Ring, Wireless LAN, Wireless PAN, Wireless MAN, Bridging and Virtual Bridged LANs. An individual working group provides the focus for each area. Decisions by the IEEE 802 task groups and working groups will shape communications for years to come. For more information about the IEEE 802 LAN/MAN Standards Committee, see http://grouper.ieee.org/groups/802/.

About the IEEE Standards Association

The IEEE Standards Association, a globally recognized standards-setting body, develops consensus standards through an open process that engages industry and brings together a broad stakeholder community. IEEE standards set specifications and best practices based on current scientific and technological knowledge. The IEEE-SA has a portfolio of over 900 active standards and more than 600 standards under development. For information on the IEEE-SA, see: http://standards.ieee.org.

About the IEEE

IEEE, the world’s largest technical professional association, is dedicated to advancing technology for the benefit of humanity. Through its highly cited publications, conferences, technology standards, and professional and educational activities, IEEE is the trusted voice on a wide variety of areas ranging from aerospace systems, computers and telecommunications to biomedical engineering, electric power and consumer electronics.
