The paper deals with the evaluation of channel allotment criteria in a mixed cellular environment composed by a regular grid of macrocells, plus a number of microcells deployed in the most congested areas. The optimum allotment of the resources between microcells and macrocells, which is a key issue for future personal communication systems, has to be tailored on the basis of their different functionalities. The approach is quite innovative since the analysis is carried out considering real traffic statistics, which are characterised by peaks and fluctuations resulting in uneven traffic loads on different cells. Different propagation models for macrocells and microcells have been adopted. Finally, the impact of the allotment of frequency resources to microcells and macrocells is analysed.
