Research output: Chapter in Book/Report/Conference proceedingConference Contribution (Conference Proceeding)


A three dimensional 'image-based' ray tracing algorithm for indoor environments is presented. The model is capable of predicting wideband as well as narrowband propagation information for single floor scenarios. To show the practicality of such a model, the ray tracing engine has been used to investigate a typical indoor environment. Using this model, the relative importance of reflection, transmission and diffraction are considered and the influence of internal objects such as windows, doors and partitions studied. Since the model can consider externally reflected and diffracted rays, the impact of external building structures on the received power and RMS delay spread is examined
