BeaconFence is a new developer proximity solution that provides GPS-free indoor and outdoor location tracking as well as events that occur as the user of the smartphone application moves within an area or zone.
BeaconFence has a mapping technology that allows you to define rectangular and radial zones for any physical layout. With the BeaconFence technology, you can track location information down to inches; furthermore, you can track intersections, like enters and exits with callback events.
Why this is so cool technology? Because GPS is not good while you are in the building. BeaconFence technology can be used in buildings, retail shops, or factory floors.
