Application of some theoretical models for coverage prediction inmacrocell urban environments

The implementation of cellular mobile radio (CMR) systems in urban environments has been the main reason for the development of theoretical models to predict coverage. This paper reports the results obtained on comparing the estimates of several models with measurements made in two distinct types of urban environment. The models used for the final diffraction loss calculation produced very similar results in most cases, with almost identical computational costs. Nevertheless, for multiple diffraction loss, the advantages of using a regular or an irregular building profile modeling depend on the degree of regularity of building height and spacing in the area under study, as well as on the computation times desired for the calculations
