Differentiating users by frequencyDifferentiating users by frequency

Differentiating users by timeDifferentiating users by time

Differentiating users by codeDifferentiating users by code

Spread Spectrum Improved call quality, with better and more consistent sound and enhance

privacy Short PN, long PN and Wash codes are used for coding

Multiple Access Code Division: Frequency reuse and guarantee large system capacity

Soft Handoff and Softer Handoff Seamless communication with low calls dropping

Power Control Ensure optimum power level with least interference to other channels,

reducing Near and Far Effect and thus increasing system capacity Low radiation and longer battery usage time

Diversity Receiver (Rake Receiver) Achieve signal gain and low Multi-path Effect

Voice Activation Lower transmitting power and high quality

Technical Features of CDMA

Technical Advantages of CDMA For the Telecom Service Provider High Efficiency of Frequency Utilization Simple Frequency Planning Large Capacity Network Smooth migration to 3G Abundant services

For the Subscriber Crystal-clear Voice Quality Good Anti-jamming Inter system soft handoff reduces calls dropping Low radiation and Long Standby time (long battery duration) Reliable Privacy
