Abstract :
A deterministic approach for the prediction of path loss and channel impulse response of UHF radio links in built-up areas, including building penetrating links, is presented. The wave propagation prediction is based on ray-tracing algorithms implemented in the URBAN-MICRO model. A brief description of this model is given and comparisons with path loss measurements are shown. Further an extension of the URBAN-MICRO model for in-building antenna locations, resulting in the new model URBAN-MICRO-I, is presented. Both models use vector oriented building data and raster based topography data. Arbitrary outdoor base station heights can be handled by the models, which is a very important feature from a practical point of view
