Geofencing is the use of GPS or RFID technology to create a virtual geographic boundary, enabling software to trigger a response when a mobile device enters or leaves a particular area. The use of Geofence is called Geofencing.

It requires Location aware device of a location-based service (LBS) user entering or exiting a geo-fence. This activity could trigger an alert to the device’s user as well as messaging to the geo-fence operator. This info, which could contain the location of the device, could be sent to a mobile telephone or an email account.

The technology has many practical usages-

  1. Network logs can record geo-fence crossings to document the proper use of devices and their compliance with established policies.
  2. An ankle bracelet can alert authorities if an individual under house arrest leaves the premises.
  3. When the home owner’s Smartphone leaves the home’s geo-fenced perimeter, the thermostat lowers itself to a pre-defined temperature.
  4. A network administrator can set up alerts so when a hospital-owned iPad leaves the hospital grounds, the administrator can monitor the device’s location and lock it down to prevent it from being used.
  5. An employee’s smart card will send an alert to security if the employee attempts to enter an unauthorized, geo-fenced area.
  6. A sporting event can use geo-fencing to create a temporary no-fly zone that prevents drones from crossing a defined perimeter.
  7. Geo-fencing can alert a dispatcher when a truck driver breaks from his route.
  8. Small businesses can text an opt-in customer a coupon code when the customer’s Smartphone enters a defined geographical area.
  9. An ankle bracelet can alert authorities if an individual under house arrest leaves the premises.
  10. An airline app can define a Geofence around an airport when a flight reservation is near boarding time. When the device crosses the Geofence, the app can send a notification that takes users to an activity that allows them to get their boarding pass.
