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 work 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.MATLAB is used to realise the blocking probability formula so developed such that numerical and graphical results are outputted.Results show the effect of variations in network parameters on CDMA.Thus the model is applicable in network planning and dimensioning.
