Abstract

A system and method for communicating energy or water consumption related information from a plurality of RF enabled peripheral devices in a home, such as utility meters, thermostats, appliances and load controllers. The system includes a home gateway that enables wireless RF peripheral devices in a home to communicate to a WAN network, such as the internet. The home gateway contains a RF multi-band software defined radio that is fully programmable and configurable so that it is capable of emulating, transmitting, and receiving any of a plurality of RF protocols over multiple RF channels. The home gateway supports commonly used interfaces for communicating to the public WAN network. The system also supports future peripherals that do not exist today due to the flexibility of the home gateway.

Claims

1. A system for communicating energy related information from a home to a remotely located utility provider, the system comprising:

a plurality of devices positioned in the home, the devices each being configured to communicate using only one of a plurality of RF protocols;

a home gateway positioned in the home and operable to simultaneously communicate with each of the plurality of devices utilizing one of a plurality of different RF protocols over an RF local area network (LAN) and to the utility provider over a wide area network (WAN);

at least one of the plurality of devices positioned in the home also being configured to communicated to an advanced metering infrastructure (AMI) system independently from the communication to the home gateway;

wherein the home gateway comprises a multi-band, software defined radio and a protocol emulator, wherein the protocol emulator controls the operation of the radio such that the home gateway simultaneously communicates to more than one of the plurality of devices using more than one of the plurality of RF protocols,

wherein the protocol emulator is selectively programmable to add new RF protocols for communication in addition to the plurality of RF protocols already present.

2. The system of claim 1 wherein the plurality of devices include utility meters and peripheral devices located within the home.

3. The system of claim 1 wherein the at least one device communicates to the AMI system using a proprietary RF protocol.

4. A method of operating a home gateway to communicate between a plurality of RF enabled devices and a utility, the method comprising the steps of:

positioning the home gateway in a home;

configuring a protocol emulator of the home gateway to operate a multi-band radio of the home gateway to communicate with the plurality of RF enabled devices using a plurality of different RF protocols;

positioning the plurality of RF-enabled devices within communication range of the home gateway;

configuring the protocol emulator to simultaneously communicate with the plurality of RF enabled devices using the plurality of different RF protocols assigned to the plurality of RF enabled devices;

transmitting information between the home gateway and the plurality of devices utilizing the RF protocol assigned to each of the devices;

operating the multi-band radio to communicate information to and from the plurality of RF enabled devices;

communicating the received information from the plurality of RF enabled devices to the utility over a wide area network; and

communicating from one or more of the plurality of RF enabled devices to an advanced metering infrastructure (AMI) system independently from the communication to the home gateway.

5. The method of claim 4 further comprising the steps of:

positioning an additional RF enabled device within range of the home gateway; and

providing a software protocol to the protocol emulator for communication with the additional RF enabled device such that the multi-band radio can communicate to the additional device utilizing the downloaded RF protocol.

6. The method of claim 5 wherein the software protocol is provided to the home gateway through the wide area network.

7. The method of claim 4 further comprising the step of storing a plurality of RF communication protocols within the protocol emulator, wherein the plurality of RF enabled devices communicate utilizing the stored RF protocols.

8. The method of claim 4 further comprising the step of selectively communicating information from the home gateway to a second home gateway upon interruption of the wide area network to the home gateway.

9. The method of claim 4 wherein the home gateway is incorporated into one of the plurality of RF enabled devices.
