In this paper, for supporting more variable services than typical DSRC, brand call service, truck and an official vehicle services, etc. using location information and mobile communication network could be adapted. emergence helping information providing, multimedia service that are wireless internet, movies and games, are increasingly needed for competible wireless car mobile terminal. Those needs would make a development a wireless telemetries system based on WiBro interface in ubiquitous vehicle environment. We analysis the proposed telematics mobile terminal using simulation which is concerned about fixed bandwidth and dynamic bandwidth.
