Outdoor-to-indoor propagation — Accurate measuring and modelling of indoor environments at 900 and 1800 MHz

Indoor network coverage has become more important since the majority of mobile data traffic is delivered to indoor environments. With the deployment of femto cells, the way in which signals penetrate into buildings and interfere on the inside with others has become a central aspect, because high data rates rely on good SINR. Therefore, an exhaustive measurement campaign has been carried out in order to prove the usability of classical models and to discover supplementary key facts. In addition, a prediction model has been set up that considers the dominant effects.
