ABSTRACT:
A location detection system for locating a mobile device placing an emergency 911 call within a facility having a distributed antenna system. The location detection system includes one or more detection units located within the distributed antenna system and being associated with one or more antennas. Each detection unit monitors a dedicated emergency 911 channel for activity and alerts a monitor unit if activity is detected. The monitor unit determines the location of the antenna receiving the emergency 911 call based upon the identity of the detection unit.
