Power loss models for the portable phone "Pointel" in a typical indoor environment
Résumé
Using a simplified and improved measurement system operating in the frequency domain, a typical obstructed line-of-sight (OLOS) indoor environment is investigated. From the measured data, three large-scale models for the power-distance relationship are discussed. In order to obtain a comparison between these models and to select the most accurate model, two criteria are proposed: the correlation coefficient and the Euclidean distance between the measured and the estimated power loss values. These two criteria indicate the same hierarchy for the considered models.
