In one embodiment, a distance between an observing communication device and a reference communication device and a distance between the observing communication device and a target communication device are determined. An exchange of messages between the target communication device and the reference communication device is detected at the observing communication device. Timing information associated with the exchanged messages is determined at the observing communication device. A distance between the target communication device and the reference communication device is determined at the observing communication device based, at least in part, on the distance between the observing communication device and the reference communication device, the distance between the observing communication device and the target communication device, and the timing information associated with the messages exchanged between the target communication device and the reference communication device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Third party device location estimation in wireless communication networks","description":"A third party device location estimation mechanism can be implemented in a wireless communication network.
