P8.5 - Ultrasonic Indoor Positioning for Umpteen Static and Mobile Devices

H. Schweinzer
Indoor ultrasonic (US) systems for locating mobile devices are presented since years differing in operating modes and various parameters. This paper depicts the alternatives and derives a positioning system, called LOSNUS (Locating of Sensor Nodes by UltraSound), which is directed at supporting the locating of umpteen static devices together with mobile nodes. In factory and building automation numerous sensor and actuator devices are often deployed which are connected to a control network or a wireless...
