Accurate positioning of wireless devices using short-range link-technologies is interesting for a number of applications including tracking, location-based services, and context sensitive networking. In this paper, accuracy and timing aspects for an indoor positioning method based on triangulation using signal strength measurements of Bluetooth links are analyzed experimentally and via simulation models: in the approach chosen in this paper, the delay to obtain signal strength measurements is determined by complex interactions of the Bluetooth inquiry procedure, which are analyzed in detailed simulation experiments. The location accuracy analysis is performed experimentally for the setting of an indoor corridor scenario including multi-path propagation properties.
