PISCATAWAY, N.J., USA, 17 January 2007 The IEEE has approved the start
of the fifth member of its family of WAVE radio standards, which will act integrate
the other WAVE standards so they work well together. This body of standards sets
specifications for a new breed of wireless communications that 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(TM), “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 need when communicating in mobile vehicular environments.
WAVE
technology (also called Dedicated Short Range Communications or DSRC) is a short-to-medium-range
radio link that will allow passenger vehicles in the U.S. to communicate with
roadside stations and other WAVE-equipped vehicles. It operates at 5.9 GHz and
will complement cell phones by offering high data rates. Its upper layer protocols
and services requirements are described by IEEE 1609 standards that build on IEEE
802.11(TM) and P802.11p(TM) local area network standards.
In addition to
giving drivers information to help them reach their destinations safely and efficiently,
WAVE radio will open a new generation of transportation applications, such as
Internet access, arranging for lodging, and ordering goods and services in transit.
WAVE radio will operate in the 5.9 GHz band as authorized by the US Federal Communication
Commission for intelligent transportation systems.
The auto industry is
developing ways to add this technology to cars, radio chip manufacturers have
built prototype WAVE radios, and testing of a prototype WAVE radio system is underway
in California. In addition to 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:
· IEEE 1609.1(TM), "Trial-Use Standard for
Wireless Access in Vehicular Environments (WAVE) - Resource Manager," which
describes the flow of the command-response interchange between multiple remote
applications and the resource manager. · IEEE 1609.2(TM), "Trial-Use
Standard for Wireless Access in Vehicular Environments - Security Services for
Applications and Management Messages", which covers methods to make WAVE
messages secure against eavesdropping, spoofing and other attacks. ·
IEEE 1609.4(TM), “Trial Use Standard for Wireless Access in Vehicular Environments
(WAVE) – Multichannel Operation”, which provides an interface to the
medium access control of the communication stack and provides for multi-channel
operation versus the single channel of IEEE 802.11p(TM). A fourth standard,
IEEE P1609.3(TM) is under development.
IEEE 1609 standards provide a radio
communication component to support the US Department of Transportation's Vehicle
Infrastructure Integration and Intelligent Transportation System program. These
standards are sponsored by the Intelligent Transportation Systems Committee of
the IEEE Vehicular Technology Society.
About the IEEE Standards Association
The IEEE Standards Association, a globally recognized standards-setting body,
develops consensus standards through an open process that brings diverse parts
of an industry together. These standards set specifications and procedures based
on current scientific consensus. The IEEE-SA has a portfolio of more than 870
completed standards and more than 400 standards in development. For information
on IEEE-SA see: http://standards.ieee.org/.
About the IEEE The IEEE has more than 375,000 members in approximately
150 countries. Through its members, the organization is a leading authority on
areas ranging from aerospace, computers and telecommunications to biomedicine,
electric power and consumer electronics. The IEEE produces nearly 30 percent of
the world's literature in the electrical and electronics engineering, computing
and control technology fields. This nonprofit organization also sponsors or cosponsors
more than 300 technical conferences each year. Additional information about the
IEEE can be found at http://www.ieee.org.
