A CDPD Performance Model for an Intelligent Transportation System Architecture Evaluation
Loral’s effort to develop an architecture for a nationwide integrated Intelligent Transportation System required an evaluatory communications design. For the wireless component, the Loral team focused on CDPD. This paper details the model that was developed using the OPNETTM3 tool and the simulations that were run to predict performance for an urban scenario in the year 2012. The results indicate that current CDPD technology can handle the required loads, which are primarily associated with route guidance.
