A geofence can be dynamically generated (as in a radius around a point location) or match a predefined set of boundaries (such as school zones or neighborhood boundaries). The use of a geofence is called geofencing , and one example of use involves a location-aware device of a location-based service (LBS) user entering or exiting a geofence.

Geofencing involves creating a virtual geographic boundary (a geofence), enabling software to trigger a response when a device enters or leaves a particular area. [3] Geopositioning is a pre-requisite for geofencing.
Geomessaging is a technology that allows a person or system to send a message based on any media to a device that enters or exits one or more regions. [1] Those regions can be created by using geofences, based on Latitude and Longitude, or adding beacons to the system associating those beacons with named locations.

With geofence, while both spellings have been increasing in usage since roughly 2000, "geofence" is quite dominant over "geo-fence".
