DSRC is meant to be a plement to cellular munications by providing very high data transfer rates in circumstances where minimizing latency in the munication link and isolating relatively small munication zones are important. This briefing outlines an approach to using the selected DSRC technology in a way that maximizes the realization of the user requirements. The topics listed below are discussed in the following charts and were used in the development of the concept of operation: A. Applications B. User Requirements Excerpts C.
