Ultra-Wideband provides high temporal resolution of multipath components of the propagation channel. Therefore a channel impulse response obtained from a certain transmitter can be seen as a signature of its position. This work investigates the possibility to perform rough localization in rich multipath environment by means of those signatures. We refer to georegioning as the intention to associate a received signature to a certain region in a room. A measurement campaign has been performed collecting a huge number signatures in 22 different regions in a warehouse-like scenario. By means of the measured data the performance of the geo-regioning approach is demonstrated. A simple geo-regioning algorithm is proposed and the impact of important algorithm parameters is pointed out.
