ABSTRACT:
A system includes antenna control stations and a system interface. Each antenna control stations directs an orientation of an associated antenna to search for an identification signal associated with a mobile phone. The antenna control station communicates a detection response describing the orientation of the associated antenna. The system interface computes the location of the mobile phone based on the detection responses received from the antenna control stations.
