ABSTRACT

This contribution presents measurements and analysis of the outdoor-to-indoor propagation characteristics in the 1.35 GHz band. Indeed, in such a configuration, most of the results already published in the literature deal with an analysis of the path loss variation as a function of the position of the receiver inside the building, thus when it moves from a light indoor configuration to deep indoor. In this paper we extend these results to analyze the change in wave polarization, expressed in terms of cross-polar discrimination factor, and to study the distribution of the direction of the rays for many positions of the receiver inside the building. To achieve this goal, experiments have been carried out with a real time MIMO channel sounder, designed and developed by the authors, and based on flexible software architecture. After describing the main features of the sounder and the geometrical configuration of the experiments, results on narrow band and wide band analysis will be described.
