Abstract: A system for communicating across conventional HVAC wiring is provided. The system includes a communication device having a communication module capable of inducing low power, high frequency current signals into a single control wire coupling, for example, a thermostat with a compressor. The communication module includes a power supply module that draws power sufficient to operate the communication module from the existing HVAC wiring, so as to eliminate any need for batteries or external power sources. A second communication module may be coupled to the single control wire. The second communication module operates as a transceiver sending communication signals to, and receiving communication signals from, the communication module. In one embodiment, the communication module is disposed within a building, for example coupled to an electronic thermostat, while the second communication module is disposed outside the building near the compressor.

Abstract: A distribution system architecture provides a platform for communicating energy services and non-traditional services as part of an overall communications infrastructure. A native message, regardless of the source of the message's application, is divided into data packets that are encapsulated and transmitted through an open network from a headend to a gateway or from the gateway to the headend. The receiver of the encapsulated data reassembles the original native message from the encapsulated data packets. The encapsulating information can include a header which incorporates a time division multiple access transport scheme. The encapsulating information at the headend provisions the gateways from the headend in a real time fashion and the headend dynamically allocates the gateway functions of listening, talking and acknowledging.
