Automatic WLAN Localization for Industrial Automation

The increasing WLAN development in industrial environments opens possibilities for location based services such as asset-tracking and workflow optimization. This paper presents our current research to develop a WLAN-localization system that fulfils the requirements of industrial automation: scalability and 5-10m localization accuracy. Our envisaged system produces the training data automatically using automatic measurements, and model calibration. The suggested approach avoids the effort for walk-around and extensive manual measurements and is stable under environmental changes, while still achieving all accuracy equivalent to state-of-the art technology. Preliminary evaluation shows an average accuracy of 3.7m (12ft).
