Geo-fencing
Geo-fencing
(geofencing) is a feature in a software program that uses the global
positioning system (GPS)
or radio frequency identification (RFID)
to define geographical boundaries. A geofence is a virtual barrier.
Programs that
incorporate geo-fencing allow an administrator to set up triggers
so when a device enters (or exits) the boundaries defined by the administrator,
a text message or email alert is sent. Many geo-fencing applications
incorporate Google Earth, allowing administrators to define boundaries on top
of a satellite
view of a specific geographical area. Other applications define
boundaries by longitude and latitude or through user-created and Web-based
maps.
The technology
has many practical uses. For example, a network administrator can set up alerts
so when a hospital-owned iPad leaves the hospital grounds, the administrator
can disable the device. A marketer can geo-fence a retail store in a mall and
send a coupon to a customer who has downloaded a particular mobile app when the
customer (and his smartphone)
crosses the boundary.
Geo-fencing has
many uses including:
Use
|

When a truck driver breaks from his route, the dispatcher
receives an alert.
|
Human resource management
|
An employee smart card will send an alert to security
if an employee attempts to enter an unauthorized area.

|
Network logs record geo-fence crossings to document the
proper use of devices and their compliance with established rules.
|
Marketing
|
A restaurant can trigger a text message with the day's
specials to an opt-in customer when the customer enters a defined
geographical area.
|
