    Abstract: A powerline communication diversity coupling mechanism may implement a transformer coupling unit. The transformer coupling unit can receive a communication signal to be coupled to a plurality of powerline communication channels for transmission in a powerline communication network. The transformer coupling unit can split the communication signal into a plurality of communication signals for transmission. The transformer coupling unit can couple each of the plurality of the communication signals to a corresponding one of a plurality of the powerline communication channels for transmission in the powerline communication network. Also, the transformer coupling unit can receive a plurality of communication signals on each of a plurality of powerline communication channels. The transformer coupling unit can combine the plurality of the communication signals into a communication signal.

  • Patent number: 8605798
    Abstract: Systems and methods for power and bidirectional data transmission using a plurality of wires. A multiphase digital signal is downlinked from a main unit to a remote unit over the plurality of wires and is converted to a DC power signal used to power the remote unit. Uplink data is sent from the remote to the main over one selected wire during a predetermined time period for an uplink transmission by amplitude modulating the received digital signal at the remote. During an uplink, the output impedance of the line driver in the main unit connected to the wire selected for the uplink is increased to allow for the uplink amplitude modulation. The modulated signal is maintained within the noise margins of the digital circuits in the main and remote units.

  • Patent number: 8482402
    Abstract: A communication system includes communication protocols that allow a single network or multiple neighboring networks to increase resource sharing and reduce mutual interference and increase their overall throughput. Various protocols apply to homogenous networks in which all power line communication (PLC) devices of multiple networks are interoperable with respect to full power line communication in a common PHY and to heterogeneous networks having non-interoperable PLC networks which do not employ a common PHY. As to heterogeneous networks, a protocol herein enables coexistence via a special signaling scheme. In homogeneous networks, all nodes can communicate with each other using a common PHY, so that information about one PLC network can be transferred to another PLC network. In heterogeneous networks, not all PLC networks can exchange information using their own native PHY.

  • Patent number: 8427300
    Abstract: In one embodiment, an apparatus includes a circuit coupled to a line, where the circuit may power a device, and where the power is transmitted to the device over the line as a pulse-width modulated signal. The circuit may set a duty cycle of the pulse-width modulated signal in order to transmit a determined power level to the device. The apparatus may vary a frequency of the pulse-width modulated signal to transmit data to the device while the duty cycle of the pulse-width modulated signal is fixed in order to continue to transmit the determined power level to the device. A variation in the frequency of the pulse-width modulated signal may be detectable by the device and represents at least a portion of the data.

  • Patent number: 8421614
    Abstract: A mechanism is provided for providing reliable redundant data communications. The mechanism issues a request for data to a set of powered elements using a set of secondary communication channels in response to a reduction in a level of communications being detected. The set of secondary communication channels comprises one or more alternating current power lines and the request is sent as data injected onto the alternating current power lines to the set of powered elements. The mechanism receives the data using the set of secondary communication channels from the set of powered elements, analyzes the data to determine a set of recovery actions to restore the level of communications, and issues the set of recovery actions to the set of powered elements using the set of secondary communication channels.

  • Patent number: 8390441
    Abstract: A power device may include channels coupled to conductors in lines, where each one of the channels is coupled to a different one of the lines than the other channels and where the channels deliver direct current power signals over the conductors to the load devices. Each one of the load devices may be powered by a different one of the direct current power signals. The power device may include a power communicator that communicates with the load devices over the conductors that propagate the direct current power signals. The power communicator may determine a target power level for the load devices based on the communication over the conductors. The load device may adjust an amount of power in the direct current power signals in order to match the target power level.
