Ray tracing is a powerful method to determine the radio channel characteristics. Especially, for broadband transmission and to determine the angle of incidence, which is becoming more important with the introduction of directional antennas, ray tracing provides useful and realistic results. Two basic methods of ray tracing can be distinguished, the imaging method and the ray launching method. The latter one is preferable for large scenarios with many objects that are substance of reflection, transmission and diffraction. Ray launching owns the problems of detection gaps and double counts. To avoid these error sources a new twofold detection approach is introduced. Comparisons of the simulation results with reference values obtained by ray imaging show better agreement for the twofold method than for the common method. Furthermore, for validation of the simulation results broadband measurements have been performed and comparison with measurements show good agreements, too.
