A UTD Wave Propagation Model For Microcell Planning Purposes

The system planning methods for the new services in individual communication (mobile radio, PCN) require coverage prediction mainly in urban areas. Characteristic for the wave propagation in these areas are multipath effects due to multiple reflection and diffraction between buildings. Since the mutual coupling between surface elements (building walls) is more significant in urban areas than in natural terrain, an approach as given by Lebherz et al in [1-3], neglecting mutual coupling effects between surface elements, is not sufficient. Thus a new UTD propagation model for urban areas has been developed. The propagation model is described, results are given and compared with measured data.
