Abstract: This paper presents a simulation tool for the fast calculation of the impulse response on infrared (IR) wireless indoor channels. We used Phong's model to approximate the reflection pattern of the indoor surfaces upon which a Monte Carlo ray-tracing method allows us to evaluate the impulse response. We also present computer simulation results showing that the use of Phong's model can lead to differences with respect to Lambert's model in the evaluation of the impulse response when surfaces present a high specular component.
