The simulation of wave propagation based on the uniform theory of diffraction (UTD) allows for the prediction of the mobile channel with wide band characteristics, especially within indoor and micro-cellular environments. Besides the line-of-side propagation, effects due to reflections and diffractions can be taken into account. The efficient simulation is based on advanced visibility and ray tracing algorithms.
