  4. FDMA, TDMA & CDMA Differentiating users by frequency Differentiating users by time Differentiating users by code

  5. Technical Features of CDMA • 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

  6. 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
