  • SYSTEM AND METHOD FOR ADAPTIVE USE OF GEOFENCE PARAMETERS
    Publication number: 20140337123
    Abstract: A method is provided for ascertaining the proximity of a mobile technology platform to a location. The method includes comparing the percent overlap of a first geofence associated with the mobile technology platform with a second geofence associated with the location; if the percent overlap is greater than a predetermined threshold value T1, wherein T1<100%, then marking the mobile technology platform as having entered the second geofence, and otherwise marking the mobile technology platform as not having entered the second geofence.
