In dense environments, for example residential, office or industrial, the predominant type of link within a real time localization system (RTLS) is non-line-of-sight (NLOS). In some NLOS scenarios the signal-to-noise-ratio (SNR) of the first incoming Ultra Wideband (UWB) pulse content is much below 0 dB and the shape of the pulse is distorted. Accordingly(More)
In this paper, a concept of a system for wireless locating and data communication for industrial applications is proposed. The proposed system employs ultra-wide band radio for decentralized spatial localization of mobile sensor nodes and for communication. Due to the robustness UWB radio transmissions, it can be used in shop floor environments, e. g. for(More)
Lateration based real time locating systems (RTLS) require anchor nodes with known positions to calculate the position of a mobile target. The geometry of the anchor nodes constrains the accuracy of the locating. In complex environments such as ships or factory floors, obstacles in the line of sight between target and anchors decrease the precision(More)
