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 have been in use since 2004 for multiple online mapping applications since their development by Dr. Vinay Rawlani at the University of Missouri-Columbia.
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 is a critical element to telematics hardware and software. It allows users of the system to draw zones around places of work, customer's 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.
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.
With in increasing popularity of mobile advertising, geofencing has been employed to distribute location specific ads to customers on their mobile devices. ,,
