Abstract
Embodiments described by the present disclosure provide improved systems and methods for determining the location of a mobile device. In one embodiment, a system comprises a distributed antenna system (DAS) configured to relay signals to and from the mobile device. Further, the DAS comprises a hub unit; and multiple remote antenna units coupled to the hub unit, wherein signals relayed between the remote antenna units and the hub unit are delayed such that different signal paths between the remote antenna units and the hub unit have different delay times. The system also comprises a base station coupled to the hub unit, wherein the base station receives the signals from the hub unit and determines the delay of signals transmitted between the mobile device and the base station, wherein the system determines the location of the mobile device by using the delay for RF pattern matching.
