Executive Summary

This paper presents teletraffic modelling in cellular networks operating with Code Division Multiple Access (CDMA) to assist in capacity analysis of such systems using statistical means. Since the introduction of CDMA, owing to capacity edge over other multiple access techniques, there is the need for tools that will assist in ensuring quality of service and proper network dimensioning. This paper produces a model useful for capacity analysis. This is achieved by modelling telephone traffic using lognormal assumptions to generate a CDMA blocking probability that is adapted into Erlang B formula for capacity calculations.
