â—† cdma2000: A Third-Generation Radio Transmission Technology

The requirements of a third-generation radio transmission system include support for multimedia services, global roaming, operation in multiple environments both fixed and mobile, and high-speed data services. The cdma2000 radio transmission technology (RTT) is based on the evolution of the current cdmaOne* system to a multimedia system that offers additional capacity and service enhancements. While meeting the requirements of a third-generation wireless system, the cdma2000 RTT maintains backward compatibility with currently deployed cdmaOne networks worldwide, providing a smooth migration path from second- to third-generation systems.
