Abstract
In this paper the sensitivity of a 3D image- based ray tracing model for microcellular environments (l-21 is investigated. The variation of the received power is examined for different ray permutations and wall characteristics. The predictions of the different configurations are compared with narrowband measurements performed in a typical urban area. The analysis illustrates that with 5 orders of reflection and 1 order of diffraction the model produces reliable results. It is also shown that good agreement with measured results can be obtained for wall conductivity in the order of lO"S/m and values of relative permitivity around 5.Keywords
