An empirical model for propagation loss prediction in indoor mobile communications using Pade approximant

This paper presents a model for path loss prediction in indoor mobile communications. It uses the free-space loss model added to an empiric function (based on Pade approximant), and a term that describes the sign randomness. In order to validate this model, a measurement campaign was accomplished at a typical 5 floors building of a university. The loss predicted by this model had a mean error of 4.78 dB and standard deviation of 6.05 dB in relation to the measured data. The proposed model doesn´t need accuracy information of the environment in study, besides being adaptable to any indoor environment.
