Ray tracing based path loss prediction in two microcellular environments

The application of diffraction theory and geometrical optics for modeling the propagation in microcellular urban environment is investigated. The model simplifies the reality by considering only a two-dimensional geometry where the building walls are modelled by segments. This paper presents comparisons between several predictions and measurements in the microcell environments found in two different cities. The study shows the limitation of the model considered and points out the most important parameters affecting the predictions
