  • Method and system for deriving location information from utility lines
    Patent number: 8120533
    Abstract: Location systems and methods are implemented using a variety of arrangements and methods. Using one such system location information is provided in response to a utility-line arrangement propagating signals that represent a wireless radio-frequency (RF) communication originating from one or more remote transmitters. The system includes a receiver circuit communicatively coupled and responsive to the utility-line arrangement. The system also includes a signal-processing logic circuit, communicatively coupled and responsive to the utility-line arrangement. The signal processing logic circuit is arranged to derive location information from characteristics of the signals that are indicative of a location of the receiver circuit relative to the remote transmitters.
