Definition
Geofencing is a type of technology that generates a virtual perimeter of a real-world geographic area using cellular data, Wi-Fi, GPS or RFID. The geofence triggers pre-defined action once a device enters a certain geographical area.
How Geofencing Works
- Boundary setting: Start by defining the perimeter around a specific location using mapping functions in geofencing apps.
- Triggering Action: Determine the action to be taken when a GPS or RFID-tagged device enters or exits the geofenced area, such as notifications, alerts, or device commands.
- Application: Geofencing serves various purposes, including sending promotional notifications to nearby customers for businesses, monitoring attendance in workplaces, and activating smart home devices for home automation systems based on arrival or departure.
Disadvantages of Geofencing
- The target device’s location services must be switched on for it to work.
- Precision relies on the quality and strength of GPS, cellular data or Wi-Fi connections.
- Geofencing poses privacy concerns through its data collection practices.
