Abstract :
Mobile communications are influenced by multipath effects. Radio wave propagation over urban and natural terrain depends on topography and morphography. A simulation tool, URBES (urban ray beam electromagnetic simulator), is presented. It is based on astigmatic beam tracing (ABT), a deterministic method which combines ray and beam tracing. ABT can handle multiple reflections and diffractions in 3D using GO and UTD. The tool has been applied to models of different scenarios, including urban and natural terrain scenarios. Some preliminary results of a validation activity are presented, showing a fair agreement with published measurements and results of other methods.
