  • Publication number: 20080031367
    Abstract: A passive bypass device for providing a data path around a power meter is provided. The device may be communicatively connected to two low voltage power line energized conductors on a first and a second side of a power meter. The energized power line conductors conduct both the data signals and the power. The bypass device includes a filter that causes the power to pass through the power meter while allowing the data signal to pass around the power meter thereby providing a substantially non-attenuated data signal path. The bypass device may include a first and second data path for the first and second energized conductors and with each path having a high pass filter and a fuse communicatively connected to its respective energized conductor on each side of the power meter.

  • Publication number: 20070222579
    Abstract: A power line communication device configured to facilitate communications over a low voltage power line between a downstream user device and an external power line communication device is provided. In one embodiment, the device may include a communication module configured to communicate over a low voltage power line and a controller configured to control the module. The controller is configured to operate the module in a first configuration in which all repeating is disabled; and a second configuration wherein upstream repeating is enabled and downstream repeating is disabled. The controller may transition from the first configuration to the second configuration in response to a command received via the low voltage power line or upon determining that a triggering event has been detected such as an unacceptable data rate, error rate, or noise detection. In some embodiments, the device may form part of a utility meter and also transmit utility data to the power line communication device.

  • Publication number: 20070054622
    Abstract: In a hybrid communication system a wireless communication link is maintained between a power line communication medium and a non-power line communication medium. Wireless communication is established within an unlicensed frequency band and monitored for quality. If the quality falls below a threshold, a wireless communication link is established within a licensed frequency band. The wireless link may be maintained between a power line communication system (PLCS) backhaul point and an internet protocol (IP) network access point, and/or between a PLCS endpoint communication interface and a premises communication device.
