Optimizing the computation time of radio coverage predictions for macrocellular mobile systems

This paper presents a method which optimises the computation time of the predictions of radio coverage for micro-cellular systems, no matter what propagation model is used. The principle consists in reducing the number of application points of the propagation model in relation to the classic technique. The proposed method is based on a multi-resolution analysis of measured signals carried out around 2 GHz, and on an electromagnetic analysis of the propagation environment. The performances of the method are evaluated in terms of the reduction in computation time and the effect on accuracy, as compared to the classic technique.
