Overview

Standards for dedicated short range communication (DSRC) are intended to meet the requirements of applications that depend upon transferring information between vehicles and roadside devices as well as between vehicles themselves. Typically, this type of communication occurs between moving vehicles entering a communications zone and fixed roadside communication equipment or directly between moving vehicles. DSRC provides the foundation for a variety of applications including vehicle safety, automated tolling, enhanced navigation, traffic management and many others.

What are these standards for?

This standard, ASTM E2213-03 - Standard Specification for Telecommunications and Information Exchange Between Roadside and Vehicle Systems - 5 GHz Band Dedicated Short Range Communications (DSRC) Medium Access Control (MAC) and Physical Layer (PHY) Specifications, describes a medium access control layer (MAC) and physical layer (PHY) specification for wireless connectivity using dedicated short-range communications (DSRC) services. This standard is based on and refers to computer industry standards (i.e. not part of the Intelligent Transportation Systems (ITS) standards program), namely the Institute of Electrical and Electronics Engineers (IEEE) standards IEEE 802.11 - Wireless LAN Medium Access Control and Physical Layer specifications, and IEEE 802.11a - Wireless LAN Medium Access Control and Physical Layer specifications High-Speed Physical Layer in the 5 GHz band. This standard is an extension of IEEE 802.11 technology into the vehicle environment. It contains the information necessary to explain the difference between IEEE 802.11 and IEEE 802.11a for DSRC implementations. This standard defines the operating parameters required to implement a high-speed data transfer service in the 5.9-GHz Intelligent Transportation Systems Radio Service (ITS-RS) band. This also addresses potential operations in the Unlicensed National Information Infrastructure (UNII) band, as appropriate.

Who uses them?

This standard, ASTM E2213-03 - Standard Specification for Telecommunications and Information Exchange Between Roadside and Vehicle Systems - 5 GHz Band Dedicated Short Range Communications (DSRC) Medium Access Control (MAC) and Physical Layer (PHY) Specifications, is intended for equipment manufacturers and system integrators. Regulatory agencies, research consultants, toll and turnpike agencies may also be interested.

How are they used?

This standard, ASTM E2213-03 - Standard Specification for Telecommunications and Information Exchange Between Roadside and Vehicle Systems - 5 GHz Band Dedicated Short Range Communications (DSRC) Medium Access Control (MAC) and Physical Layer (PHY) Specifications, is used for wide area (multi-lane, open road) and lane-based applications to deliver high-speed, wide-bandwidth messages over short distances between vehicles entering a communications zone and roadside communication equipment. It enables accurate and valid message delivery between moving or stationary vehicles and fixed or portable roadside communication equipment through an air interface. It does not, however, include associated measurement guidelines for verification of the requirements in the standard. The high speed, assured data-delivery nature of this standard fully supports public safety applications and private enterprise delivery of information to vehicles using the UNII band, such as entertainment audio and video. Application developers and systems integrators should also consult the IEEE 1609 Family of Standards for Wireless Access in Vehicular Environments (WAVE) and the data dictionary and message sets defined for 5.9 GHz applications as specified by the Society of Automotive Engineers (SAE) J2735.

Scope

This standard, ASTM E2213-03 - Standard Specification for Telecommunications and Information Exchange Between Roadside and Vehicle Systems - 5 GHz Band Dedicated Short Range Communications (DSRC) Medium Access Control (MAC) and Physical Layer (PHY) Specifications, provides wireless wide-bandwidth, high-speed communications over short distances between information sources or transaction stations on the roadside and mobile radio units, between mobile units, and between portable units and mobile units. The communications generally occur over line-of-sight distances of less than 1000 meters between roadside units and moving or stopped vehicles, or between moving vehicles. This specification also offers regulatory bodies a means of standardizing access to the 5.9 GHz frequency band for the purpose of interoperable communications to and between vehicles at line-of-sight distances on the roadway.

More specifically, this standard

  • Describes the functions and services required by a DSRC- conformant and IEEE 802.11-conformant device to operate in a high-speed mobile environment;
  • Refers to IEEE 802.11 MAC procedures;
  • Defines the 5.9 GHz DSRC signaling technique and interface functions that are controlled by the IEEE 802.11 MAC;
  • Permits the operation of a DSRC conformant device within a DSRC communication zone that may coexist with multiple overlapping DSRC communication zones; and
  • Describes the requirements and procedures to provide for the privacy of user information being transferred over the wireless medium and authentication of the DSRC-conformant or IEEE 802.11-conformant devices.
