Monitor supply chains efficiently

Beep2Blue: energy-saving monitoring system with ultrasound.

The Beep2Blue system monitors supply chains in ISO container logistics and tracks assets on construction sites. Using Fraunhofer EMI’s energy-saving ultrasonic technology, it transmits sensor data from metal-shielded environments where radio connections are heavily attenuated. Inside, the Beep2Blue interface receives the data via Bluetooth and transmits it acoustically to the outside. There it is transmitted to web servers via 3G/4G wireless standards.
