FCC References Standard on Dedicated Short-Range Communications

摘要

SOME DRIVERS MAY BREEZE THROUGH toll booths, with an automatic pass doing all the work, while others are constantly scrambling for change as they approach the toll lane. In either case, it's a good bet that not many people have stopped to think much about the technology behind vehicle-to-roadside communications such as those found in toll booths and other types of drive-through payment systems. However, this technology is complex enough that an entire ASTM standard, Specification E 2213, is devoted to some of the future aspects of such communications. The U.S. Federal Communications Commission is now referencing ASTM Specification E 2213 in its current rules regarding dedicated short-range communication services in the 5.850-5.925 GHz band (5.9 GHz band). E 2213, Specification for Telecommunications and Information Exchange Between Roadside and Vehicle Systems-S GHz Band Dedicated Short Range Communications (DSRC) Medium Access Control (MAC) and Physical Layer (PHY) Specifications, was developed by Committee E17 on Vehicle-Pavement Systems and is under the jurisdiction of E17.51 on Vehicle Roadside Communication.
