System and method for emergency 911 location detection
First Claim
1. A method of location detection in a wireless communication system having a designated emergency wireless channel and having a distributed antenna system, the distributed antenna system having multiple antennas and a detection unit, the detection unit being associated with at least one of the antennas and having stored therein unique identifying information, the method comprising the steps of:
- detecting an emergency call from a mobile device by detecting activity on the designated emergency wireless channel at the detection unit; and
sending an alarm signal to a monitor unit when the emergency call is detected, said alarm signal including the unique identifying information, whereby, using the unique identifying information, said monitor unit determines a location of said mobile device based upon a location of the one of the antennas.

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.

7. A location detection system for determining the location of a mobile device placing an emergency 911 call from within an in-facility distributed antenna system for a wireless communication system, the wireless communication system having a designated emergency wireless channel, the in-facility distributed antenna system having multiple antennas, the system comprising:
-
(a) a detection unit coupled to the in-facility distributed antenna system and associated with at least one of the antennas, the detection unit having stored therein unique identifying information, the detection unit detecting the emergency 911 call from the mobile device by detecting activity on the designated emergency wireless channel at said one of the antennas, and the detection unit sending an alarm signal when the emergency call is detected, said alarm signal including the unique identifying information; and
(b) a monitor unit coupled to the in-facility distribution system for receiving said alarm signal, said monitor unit using said unique identifying information to determine a location of said mobile device based upon a location of the one of the antennas. - View Dependent Claims (8, 9, 10, 11, 12)
