The economic value on network capacity has made it a major determinant in the design of any generation of mobile technologies. For any multi-user cellular system, the measure of its economic usefulness is the peak load that can be supported within a given quality and service (QoS) availability. In this paper, we improve upon the existing Wideband Code Division Multiple Access (WCDMA) user capacity expressions in single and multi cell environments for the uplink, by integrating new parameters that affect the system. Specifically, we study and report the effect of multi-user detection and adaptive antenna gain on WCDMA users’ capacity in the presence of loading, voice activity, sectorization, power control factor and bandwidth efficiency.
