This paper discusses a new analytical model of the WCDMA radio interface. The proposed model is based on Erlang’s Ideal Grading with multi-rate traffic and different availability characteristics. Thanks to the application this model, it is possible in the proposed model to take into consideration not only the influence of interference from different cells, but also different traffic management mechanisms. The operation of the new model is presented with the example of the WCDMA interface in which selected classes of calls have introduced traffic constraint. The proposed model is characterized by its simplicity, while the results obtained with its application are characterized by accuracy that is acceptable for the model to be used in engineering calculations.
