iLOC: A localisation system for visitor tracking & guidance

Abstract

We report on an RF- and ultrasound based indoor localisation system which is used for visitor tracking in the iHomeLab laboratory: Visitors get an electronic name badge. This badge can be localised with an average accuracy of less than 10 cm deviation of its spatial position, by means of reference nodes distributed in the lab rooms. The localisation technology is based on ultrasound ranging.
