Geofencing is a combination of geography and fencing. It is a technique for locating and tracking people and objects that are not allowed to leave a certain local area. As soon as the corresponding person leaves the marked geographic (fencing) area, the geofencing system, a GPS tracker, gives a corresponding notice or alarm to the user.

On the other hand, geofencing systems can also be used for geotargeting. Once a user enters the radius determined by geofencing, he or she can be exposed to location-based services( LBS) and location-based advertising.

Another application area for geofencing is in the smart home. Here, lighting functions can be activated or deactivated as soon as a person enters or leaves a room. This geofencing is used to save energy and uses GPS, WiFi or Bluetooth to monitor virtual boundaries and trigger appropriate functions.

Geofencing by defining the radio radius

Geofencing systems work like tracking systems, but with geographically defined boundary coordinates. Depending on the concept, area of application and geographical accuracy, geofencing systems can be satellite-based or mobile radio-based. In principle, the persons, buildings, machines, events, services, etc. to be monitored are equipped with a GPS tracker with SIM card. Alternatively, with a GSM/ GPS module that transmits the geographical coordinates to the monitoring center. As soon as the entered border coordinates are exceeded, the geofencing system sends a corresponding message with the coordinates, date and time to the control center. Corresponding monitoring systems already exist as apps.

Such systems can be used in the search for persons, in the protection against theft of movable machinery, vehicles and equipment, in the monitoring of criminals with ankle bracelets or in the observance of driving routes and school routes.
