The definition of geofencing is that a geofence is a virtual perimeter for a real-world geographic area.[1] A geofence can be dynamically generated (as in a radius around a point location) or match a predefined set of virtual perimeters (such as buildings or commercial physcilities).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 also is a location based technology RFID (Radio Frequency ID) enabling many different businesses and enterprises to accurately track, market to, and effectively alert administrators when a person has entered or exited the virtual geofence. There are many uses of geofencing beyond marketing and to better understand the complexities behind it, we must explore all the nuances centered around geofencing.

What Is Geofencing In Precise Terms?
Geofencing is a location-based technology service in which a mobile, desktop or cloud-based app or other software uses GPS, RFID, Wi-Fi or cellular data to trigger a pre-programmed action when a mobile device or RFID tag or mobile device enters or exits a virtual boundary set up around a geographical location, known as a geofence. There are other forms of geofencing that can use multiple creative including programmatic video, static ads, and ctv ott advertising. That geofence can be as small as a building or home and as large as a mile or even a zip code. But it’s the placing of that defined boundary that makes geofencing possible.
