Geo-fence

Under geofencing ( portmanteau of Geography and fence [ engl. = Fence ] ) is understood in the telematic the connection between geographic information system, the location of objects and active interventions when the localized object predefined area leaves or enters ( within the imaginary fence ).

Depending on the application the location via the Global System for Mobile Communications can be drawn from the Global Positioning System reached on radio or cell level. Are sharp areas necessary, the geofence area using a card application as coordinates collection ( traversing, traverse ) must be defined. If only delineate areas so rich circles around coordinates and cell information (only in approximation circles). The geofencing areas can also be exchanged remotely controlled and enabled or disabled depending on your system.

Applications

• Monitoring of the operational area such as when rental of construction equipment, as the fees can be dependent or as protection against theft
• Car rental companies that allow the use of their vehicles only at home ( using just the network ID of the GSM network )
• Corridor along a planned route for safety-related applications, such as cash in transit
• Detecting whether checkpoints are reached at (time ) critical transports.
• Who wants to watch his child in complying with, for example, the way to school, it equips with a transmitter. For example, a smartphone locates and navigates these if required the person to where the child is located.
• Stray and disoriented people, such as dementia, as can be tracked.

The derived actions may be limited to SMS alerts, for example, directly to security organs or tampering with the vehicle (for example, starts a rental vehicle no longer ) include. Under certain circumstances, these systems can additionally also by external triggers, such as Inclination sensors are activated in motorcycles. Depending on the complexity of the task, the data from third party service providers will be collected and evaluated, which, especially in personal monitoring, is associated with additional data protection issues.

Limitations of technology

Inside buildings or vehicles, GPS reception may be disturbed. This makes it difficult to find, for example, of stolen objects when they are transported in a closed van, or makes a finding even impossible. The use of jamming devices can prevent the GPS reception. In areas where there is a weak mobile phone coverage, the GPS Tracker used for geofencing can send no more position reports.
