Abstract :
Cellular systems have become enormously popular. As of early 2001, one out of 10 people in the world (680 million) used a cellular phone. Once thought of as a luxury, cell phones are now often considered a necessity and a lifeline in time of an emergency. As the cellular market becomes saturated, service providers see new data applications as the next step in providing customers with new products and services. Advanced digital 3G technology represents a quantum leap in technology from 2G. It is expected to support many new applications and services.
