Abstract
Systems and methods for providing accurate data about the distribution of UEs after disaster include a movable eNodeB that is moved to at least three locations. The coordinates for the at least three locations are determined and the distance between the eNodeB and a plurality of UEs is measured. The location of each UE relative to the eNodeB is calculated based on the distance between the eNodeB and the plurality of UEs using trilateration. The coordinates for the UEs is then calculated based on the coordinates for the at least three locations and the determined location of the UEs relative to the eNodeB.
