area. This results in a 10-fold capacity increase when compared with analog mode. In addition, features such as soft/ softer handoff, hard handoff, and dynamic RF power control technologies combine to reduce call interruptions.

The Cellular and PCS CDMA networks consist of MSO (Mobile Switching Office), BSC (Base Station Controller), BTS (Base Station Transmission System), and MS (Mobile Station).

1xRTT system receives twice as many subscribers in the wireless section as IS-95. Its battery life is twice as long as IS-95. High-speed data transmission is also possible.

EV-DO system is optimized for data service and is much faster than 1xRTT system in applicable area.

V CAST Mobile TV uses a technology called MediaFLO. This Technology is used to broadcast data to portable devices such as cell phones and PDAs. Broadcast data includes audio and video streams, individual video and audio clips, as well as information such as stock market quotes, sports scores, and weather reports. The "F-L-O" in MediaFLO stands for Forward Link Only which means that the data transmission path is one-way, from the tower to the device. The MediaFLO system transmits data on a frequency separate from the frequencies used by current cellular networks.

The following table lists some major CDMA standards.
