Abstract
A method of determining a physical location of a device connected to a data network infrastructure including a plurality of connection points at different physical locations, the method including establishing a connection with the data network infrastructure via a cable-based transmission medium, wherein a communication signal passes via the cable-based transmission medium including at least one of the plurality of connection points. A connection point identifier is determined based, at least in part, upon the at least one of the plurality of connection points. A signal characteristic of the communication signal passing via the cable-based transmission medium between the device and the data network infrastructure through the at least one of the plurality of connection points is measured. A first physical location of the device is determined based on the determined connection point identifier, including accessing stored information associating the determined connection point identifier with location information. A second physical location of the device is determined based on the determined first physical location and the measured signal characteristic, including accessing stored information associating signal characteristics with location information.
