Abstract: Method for calculating whether an actual location of a target device is on one side of a boundary zone includes: receiving an estimated location of the target device; receiving a desired confidence level; forming a first circle with radius D, centered at the estimated location, where D is the shortest distance from the estimated location to the boundary zone; forming a second circle with radius R?, centered at the estimated location, wherein R? is determined in such a way so that a likelihood that the actual location is inside the second circle equals or exceeds the desired confidence level; forming an angle with an apex at the estimated location and rays passing through two closest points to the estimated location where the second circle intersects the boundary zone; and using a size of an annulus formed by the first circle, the second circle, and the rays to estimate whether the actual location lies on the same side of the boundary zone.
