Abstract
It is provided a method for determining a location of a mobile device. The method comprises the steps of: obtaining a first maximum distance between a first anchor point and the mobile device; generating a first circular geometrical object having a radius based on the first maximum distance; generating a first polytope encompassing the first circular geometric object, wherein all angles of the first polytope are right angles; obtaining a second maximum distance between a second anchor point and the mobile device; generating a second circular geometrical object having radius based on the second maximum distance; generating a second polytope encompassing the second circular geometric object, wherein all angles of the second polytope are right angles; finding a mobile device region as an overlap between the first polytope and the second polytope; and determining that the mobile device is located within the mobile device region.
