A optimization method for the radiocoverage prediction in mobile application

This paper presents a method which optimizes the computation time prediction of radio coverage. A solution is to reduce the number of application points of the used propagation model. For this, the method is based on a treatment by wavelet transform, on series of radio measurements realized around 2 GHz, and on a spatial analysis of the environment. This last tool allows us to define the evolution of the combination of electromagnetic phenomena (diffraction, reflection, line of sight) on an area. The proposed method is broken down into two stages called "learning" and "application" stages
