Abstract
A method and system for providing E911 services for a distributed antenna system uses a lookup table including round trip delay (RTD) ranges for a number of nodes of the distributed antenna system to determine a serving node for an E911 call. The method and system disclosed herein, may calculate such lookup table based on the values of the fiber delays and air delays for each node on the distributed antenna system. After determining the serving node for an E911 call, the system may use triangulation method to determine the exact location of the wireless unit generating the E911 call.
