Wireless Tracking for Industrial Services

Wireless positioning and ranging methods are being worked upon for traditional indoor locations. We apply WiFi and Bluetooth (BLE 4.0) tracking, categorically for industrial applications, by utilizing handheld mobile devices. Both are tested and evaluated in industrial environments varying in diffi-culty level. A 2D-positioning is performed using trilateration on WiFi signal transmitters. For Bluetooth tracking the fingerprint method on Received Signal Strength (RSS) is used. Fingerprinting of Bluetooth signals outperforms trilateration of WiFi signals by reducing latency, and enhancing accuracy, confidence on the system and flexibility to place the transmitters with a little economical cost.
