Abstract:
Systems and methods presented herein provide for locating user equipment (UE) in a wireless communication network. The system includes one or more wireless access points, wherein each wireless access point is operable to detect signal of a UE in the wireless communication network, and to train with the UE to establish a communication link with the UE. The system also includes a network processing element communicatively coupled to the wireless access points and operable to extract channel estimation and signal strength information of the UE from the wireless access points via said training with the UE, to compare the channel estimation and signal strength information of the UE from the wireless access points to stored signatures of the UE, and to determine a location of the UE in the wireless communication network based on the comparisons.
