UWB positioning system for elderly persons tracking in IONIS AAL platform

UWB (Ultra Wideband) indoor positioning system infrastructure is typically composed of anchor nodes deployed in the area covered by the system. The nodes are usually mounted as high as possible to provide better propagation conditions. The paper proposes a solution consisting in deploying anchors directly at the floor level. The paper includes a description of investigation of such system. The results of positioning are presented and discussed. The first path signal component propagation was experimentally investigated. Results of measurements are used for positioning system's performance analysis.
