Abstract: System and method of geo-fencing. A user equipment (UE) defines a geo-fence for an asset by tracking location coordinates of the UE with at least one sensor element, as the UE is moved around a perimeter of an area. The location coordinates of the geo-fence are transferred to a location aware device (LAD) attached to the asset. Upon determining, by the at least one sensor, that the LAD crossed the geo-fence, a notification is sent to a warning server operative to trigger a warning message to one or more recipients.
