Multi-path mitigation in rangefinding and tracking objects using reduced attenuation RF technology
First Claim
1. A system for tracking and locating one or more wireless network devices, comprising:
- a multipath mitigation processor configured to receive and process one or more signals of a network or one or more wireless network devices in communication with the network, to perform ranging of the wireless network devices, to produce a plurality of artificial frequencies based on the one or more signals so as to reduce spatial ambiguity in ranging between the one or more wireless network devices, and to calculate ranging based on the plurality of artificial frequencies.

Abstract
A method and system for identification, tracking and locating in wireless communications and wireless networks. The method and system use reference and/or pilot signals that are present in wireless communications and wireless networks. The method and system can also use RTT, TOA and time-stamping measurements/techniques to determine one or more reference signals traveling time between the Base Station (eN B) or its functional equivalent and mobile device (UE) and or network device. The method and system includes multi-path mitigations processor and multi-path mitigations techniques and algorithms which improve the track-locate accuracy. The method and system allow achieving increased accuracy by using multi-path mitigations processor and multi-path mitigations techniques and algorithms. The techniques of Digital Signal Processing and Software-Defined Radio are used.
