A communication gateway communicates with a utility meter and a meter servicing device. The communication gateway includes a one-way processing module to process communications received from a one-way utility meter and includes a two-way processing module to process communications received from a two-way utility meter. For communications from a one-way utility meter the communication gateway may decode a signal received from the meter to obtain only certain information. For example, metering information may be extracted from the signal, but a spreading sequence may not be decoded.

Portable communication gateway for utility metering devices

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. The communication signals are RF modulated signals between 5 and 50 MHz so as to take advantage of and pass across parasitic capacitances found inherent in transformers or other coils disposed within HVAC loads.
