This paper presents the statistical analysis of the wideband propagation channel in two different propagation environments: large, but almost empty museum-like hall and the factory hall comprising a lot of metal obstacles. The presence of strong and small-delayed multipath components was of interest, since it is an important factor influencing the accuracy of TOA-based positioning systems. The evaluation...
The paper presents analysis of dependence of distance determination error in localization system based on time of arrival (TOA) measurements, on beam width of antenna radiation pattern. Using narrow beam antennas some multipath components with small delays, causing errors of calculation of distance between antennas, can be eliminated and accuracy of the system can be increased. Analysis bases on results...
