The factors deciding capacity are:−

• Processing Gain
• SIGNAL to Noise Ratio
• Voice Activity Factor and
• Frequency Reuse Efficiency.

Capacity in CDMA is SOFT, CDMA has all users on each frequency and users are separated by code. This means, CDMA operates in the presence of noise and interference. In addition, neighboring cells use the same frequencies, which means no re-use. So, CDMA capacity calculations should be very simple. No code channels in a cell, multiplied by no cells. But it is not that simple. Although not AVAILABLE code channels are 64, it may not be possible to use a single TIME, since the CDMA frequency is the same. Flexible capability means that all the code channels can be PURSUED at a time, but at the expense of quality.
