SAE J2735_201504

This SAE Standard specifies a message set, and its data frames and data elements specifically for use by applications intended to utilize the 5.9 GHz Dedicated Short Range Communications for Wireless Access in Vehicular Environments (DSRC/WAVE, referenced in this document simply as “DSRC”), communications systems. Although the scope of this Standard is focused on DSRC, this message set, and its data frames and data elements have been designed, to the extent possible, to also be of potential use for applications that may be deployed in conjunction with other wireless communications technologies. This Standard therefore specifies the definitive message structure and provides sufficient background information to allow readers to properly interpret the message definitions from the point of view of an application developer implementing the messages according to the DSRC Standards. 1.1 Purpose The purpose of this SAE Standard is to support interoperability among DSRC applications through the use of a standardized message set, and its data frames and data elements. This Standard provides information that is useful in understanding how to apply the various DSRC Standards, along with the message set specified herein, to produce interoperable DSRC applications. This second published version of SAE J2735 is designated a 'Standard' rather than a 'Recommended Practice.' This implies that the data set dictionary in this version is deployable. It also creates a requirement that future revisions of SAE J2735 be backward compatible with this revision. This revision adds content to and corrects errors in the previous published Standard.
