Comparison of empirical models and deterministic models for the analysis of interference in indoor environments

In this paper, two different models for indoor electromagnetic interference prediction are compared: one empirical and another deterministic based on ray-tracing. Results for two different scenarios have been obtained, one corridor and one office building. Results demonstrate that both methods predict similar path lost. The main difference between these methods is that empirical one cannot predict local maximum and minimum due to the multipath propagation, whereas the deterministic one can do it. In this way deterministic is more accurate, although empirical is simpler.
