MeshTrack Development of a hybrid RTT-/BLE positioning system for efficient asset tracking via mesh-based Beaconing The aim of this research project was the development of a cost effective and easy to integrate indoor positioning system for industrial environments. To achieve this goal two approaches were combined: precise WiFi-based positioning via round-trip time (RTT) as well as energy-efficient positioning via Bluetooth Low Energy (BLE) signal strength. The tracked objects were thereby marked with compact and cheap BLE tags. Asset localization is realized via a smartphone app, which calculates the phones position via RTT. The app detects close-by tags via signal-strength and calculates their position using its own, known position. Through the utilization of mass-produces micro controllers and custom hardware layouts we were able to drastically reduce the systems cost. Contact persons: K. Hribernik   K. Klein B.
