  • POWER LINE AUDIO COMMUNICATION SYSTEM
    Publication number: 20080211663
    Abstract: A communication system associated with premises power distribution lines can be used to transmit audio data via the distribution lines. First and second transceivers can communicate bi-directionally over the distribution lines to transmit the audio data. The audio data can be provided by a computer coupled to one of the transceivers. One or more portions of the premises power distribution lines can be used as radiators to wirelessly transmit the audio data to one or more devices.

  • Power line communication system with system member identification
    Patent number: 7339466
    Abstract: An electric power line communication system operates with an electric power distribution system to provide, via premises power distribution lines, communication links among power line communication devices associated with the premises power distribution lines. A sensor unit and a first communication device may engage in two-way communication through the premises power distribution lines. The sensor unit may communicate data to a remote monitoring location via the first communication device or, if the first communication device is unreachable, via a second communication device. Alternatively, units associated with the premises power distribution lines may be arranged in a master-slave configuration, with a first unit configured to verify the functioning of two-way communication with the second unit. Also, a first unit may be connected to a high-voltage premises power distribution line, while a second unit may be connected to a low-voltage premises power distribution line.

  • Preventing unintended communication among power line communication devices associated with different premises power distribution lines of an electric power distribution system
    Patent number: 7034663
    Abstract: An electric power line communication system operates with an electric power distribution system to provide through premises power distribution lines highly reliable communication links among power line communication devices electrically coupled or located in proximity to the premises power distribution lines. Each power line communication device associated with a set of premises power distribution lines has an identification address. A master code identifies the power line communication devices as members of a system domain of power line communication devices associated with the set of premises power distribution lines. Association of the master code with the identification addresses renders the member power line communication devices capable of operation without unintended communication with power line communication devices associated with a separate, different set of premises power distribution lines.
