Indoor Positioning System Evaluation in Public Rooms

Indoor positioning systems present a rapidly emerging area with different technologies, applications, and operating conditions. Among them, Ultra-Wideband (UWB) is the technology that can provide increased accuracy in comparison to others, especially in indoor areas. On the other hand, as a new technology, the behavior within specific operating conditions can be described further. This work evaluates the performance of an indoor positioning system based on UWB, for the specific case of a large room within public buildings. Key characteristics under evaluation are the behavior near obstacles/walls and the comparison while applying two coordinate calculation techniques that use different number of devices. The measuring process reveals interesting aspects regarding accuracy for specific design selections and area characteristics.
