Abstract

A wireless communication device (WDEV) includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other WDEV (s) and to generate and process signals associated with such communications. The WDEV supports first communications with a first other WDEV and supports second communications with a second other WDEV. The WDEV processes the first communications and the second communications to determine whether the first other WDEV and the second other WDEV are substantially co-located at a physical location. When not co-located, the WDEV processes the first communications and the second communications based on at least one of a ranging or a location protocol to determine location information of the WDEV. Alternatively, when co-located, the WDEV stores information that indicates co-location of the first other WDEV and the second other WDEV.
