The Advantages of CDMA

Here are the advantages of CDMA:

• Meet the needs of voice and data communications wirelessly

• Has a higher channel capacity to know more simultaneous calls per channel compared to other systems.

• CDMA system offers the capacity improvement exceeds the analog AMPS system as good as other digital cellular technologies. CDMA generates a spread-spectrum scheme that randomly provides the available bandwidth of 1250 KHz for each bit rate of 9600 bps caller.

• Improved call security. Security to the nature of CDMA spread spectrum approach, and the fact that this technology was first built to provide secure communications for the military.

• Reduce noise and other interference. CDMA increases the signal-to-noise ratio, because the width of available bandwidth for the message.

• Power efficiency by extending the phone's battery life. Power efficiency by extending the phone's battery life. One of the characteristics of the CDMA is the power control, an attempt to expand the capacity of the call to maintain the constancy of the received power level of mobile phone at the base station.

• Coordination facilities of entire frequency through base-stations. CDMA system provides a soft hand-off from one base station to another as a mobile phone roaming from cell to cell. It could be possible because of adjacent CDMA cells generate the same carrier frequency, making the two base-station simultaneous serving the mobile phone roaming at the transition point of the cell. Soft hand off this fact is not detected by the user.
