  • Identification of power line locations by power line signatures
    Patent number: 8198998
    Abstract: The location of a device on an electrical power line is identified using a power line characteristic, such as a power line impedance as a function of frequency, and/or a power line transfer function identified from the first device to a second device communicating with the first device over the electrical power line. Power line information is determined by receiving a signal from a first device, determining a power line transfer function based on the received signal, and determining power line information based on the determined power line transfer function.
