In this paper we investigate the reliability of
ray tracing simulator in predicting the indoor radio channel response
through a well specified environment. The knowledge of the indoor
environment geometric and martial properties led to such site specific
modeling. We assess the simulated data by comparing the predicted
received power with real filed measurements. The good agreement between
the predicted received power and the real field measurements suggests
that a well designed site specific model can be used reliably to predict
the system behavior
