An accurate building-specific location for a mobile device requesting Enhanced 911 (E911) emergency services is provided while located indoors. A central server and associated plurality of emergency 911 wireless call detectors are programmed with Master Street Address Guide (MSAG) information, and installed throughout the walls of a given building to provide comprehensive E911 coverage. The building-specific information includes room number, floor number, column number, and/or other building information regarding the relevant detector's location in a corresponding building, and thus an accurate position of the calling mobile device within a given building. |
