GPS/LoRa based personal tracker works without mobile network
How do you keep track of exactly where service and rescue personnel are at a large event? The Fraunhofer Institute FIT has developed such a system based on both GPS and LoRa. It even works when the mobile network fails, is overloaded or in places where such a network does not exist at all.

The trackers are about the size of a car key and can be attached to clothing or stored in the pockets of security personnel. Their basic function is to continuously report the exact position of the wearer to the control center. In addition, the trackers are equipped with a kind of “panic button”. When activated, the position of the corresponding unit is highlighted on the digital location map and the responsible persons are provided with additional information.

In the course of the event, police, fire, rescue and law enforcement forces tested a total of 45 trackers. It is said that the system met all requirements. "Being informed at all times about the current position of the emergency forces is extremely helpful and greatly facilitates communication and coordination during such major events," says Malik Dine of the police authority in Bonn.

The system, consisting of trackers, antennas and the digital location map, was developed by Fraunhofer FIT as part of the EU MONICA project and is suitable for large events of all kinds. MONICA fathoms out to what extent sensor technology and the Internet of Things can improve the security of visitors at major events. The project, funded by the European Union with 15 million euros, started in 2017 and will be completed by the end of this year.
