Geofence
Encyclopedia
A geo-fence is a virtual
perimeter
for a real-world geographic area.
A geo-fence could be dynamically generated—as in a radius around a store or point location. Or a geo-fence can be a predefined set of boundaries, like school attendance zones or neighborhood boundaries. Custom-digitized geofences are also in use.
When the location-aware device of a location-based service
(LBS) user enters or exits a geo-fence, the device receives a generated notification. This notification might contain information about the location of the device. The geofence notice might be sent to a mobile telephone or an email
account.
Geofencing, used with child location
services, can notify parents when a child leaves a designated area.
Geofencing is a critical element to telematics
hardware and software. It allows users of the system to draw zones around places of work, customers sites and secure areas. These geo-fences when crossed by an equipped vehicle
or person can trigger a warning to the user or operator via SMS
or Email
. In extreme circumstances, the zones can be linked to immobilisation equipment within a vehicle
and stop the engine dead.
Other applications include sending an alert if a vehicle
is stolen
and notifying rangers when wildlife
stray into farmland
.
Geofencing in a security strategy model provides security to wireless local area networks. This is done by using predefined borders, e.g., an office space with borders established by positioning technology attached to a specially programmed server. The office space becomes an authorized location for designated users and wireless mobile devices.
