GPRS DRIVING WAP ON THE ROAD TO 3G
ABSRTACT
Mobile telephony allowed us to talk on the move. The Internet turned raw data into helpful services that people found easy to use. Now, these two technologies are converging to create third generation mobile services. In simple terms, third generation (3G) services combine high-speed mobile access with Internet Protocol (IP)-based services. But this doesnâ„¢t just mean fast mobile connection to the world wide web. Rather, it means whole new ways to communicate, access information, conduct busi ....etc

We propose a prototype pedestrian-to-vehicle communication system which uses a cellular phone and wireless communication to improve the safety of pedestrians. One of the effectual measures against pedestrian-to-vehicle accidents is to make each of pedestrians and drivers find the others and recognize the risk from out of sight and with time to spare for avoidance of accidents. A pedestrian-to-vehicle communication system was developed by using a cellular phone and a car navigation system equipped with GPS and wireless communication function. We ....etc
