    The power control in DS-CDMA cellular system is important in increasing cell capacity. Conventionally, traffic control algorithm is not necessary when subscribers are uniformly distributed over cells, while traffic control algorithm is needed to increase system capacity when subscribers are concentrated in a particular cell. In this paper, we consider power control of the base stations to increase system capacity in a non-uniformly distributed environment. We evaluated inner cell interference using methods different from those used in [1]. The outage probability is evaluated as a measure of the system capacity for a geographically uniformly distributed users model and two different non-uniformly distributed users models. The outage probability for non-uniform and uniform density was shown as a function of average users per cell. The improvement by power control on non-uniformly distributed environment was shown.
