    Abstract - (Show below) - (Hide below)

    The DSRC Standards EN 12253, EN 12795 and EN 12834, which together form a three-layered architecture for DSRC, are designed to encompass a wide range of services for different purposes in order to make the basic DSRC architecture suited for many different applications and for a wide range of possible products and systems.This document:-specifies a physical layer at 5,8 GHz for DSRC as applicable in the field of Road Transport and Traffic Telematics (RTTT).-provides requirements for the communication medium to be used for exchange of information between road-side units (RSU) and on-board units (OBU).-caters for a communication means to be used by several applications in the RTTT sector.
