Abstract
The capability of a 3-D ray tracing model to predict the indoor propagation of electromagnetic waves around a wedge is evaluated by comparing computed values and measured data. Measurements have been performed in order to validate the model, which is based on the Uniform geometrical Theory of Diffraction (UTD), and takes into account reflections from walls, floor and ceiling, and the diffraction from edges. The accuracy of predictions strongly depends on the knowledge of both the geometrical and physical properties of the environment in which the propagation occurs, and on the capability to evaluate the importance of the geometrically possible rays. The agreement between predicted and measured values points out that a UTD-based model is a satisfactory tool to account for indoor propagation.
