On the Modeling of Reflected Energy From Building Faces in Microcellular Mobile Radio Planning Tools

摘要

A semideterministic model of electromagnetic scattering from exterior urban building walls that is capable of modeling scattering from large-scale discontinuities such as ledges, windows, etc., is presented. The model is in quantitative agreement with spatiotemporally resolved measurements of scattering from a building wall at 2.4 GHz and can be used to construct relatively simple modified reflection coefficients that can be used in ray-optical microcellular planning tools.
