Abstract

A meter data collection device (20) including an antenna (52), a meter interface (60) receiving data from a meter (64), and a radio frequency (RF) stage (50). The RF stage (50) is coupled to the antenna (52) and is responsive to the meter interface (60). The RF stage (50) is operable for transmitting the meter data over a control channel of a wireless communication system.

Claims

1. A utility meter data collection device having a plurality of operational modes, comprising:

an antenna;

a utility meter interface receiving utility usage data from a utility meter;

a radio frequency (RF) stage coupled to the antenna and responsive to the utility meter interface; and

a controller in communication with the utility meter interface, the radio frequency stage and a control device,

in a first mode, the controller instructing the RF stage to transmit the utility usage data over a control channel of a wireless cellular communication system and in a second mode the controller instructing the control device to perform a predetermined action.

2. The device of claim 1, wherein the controller includes a processor and a memory, the memory storing the utility usage data.

3. The device of claim 1, wherein the utility meter interface comprises an analog to digital converter.

4. The device of claim 1, wherein said utility meter is selected from the group consisting of an electricity meter, a water meter, and a gas meter.

12. The device of claim 1, wherein in the first mode, the controller is responsive to a message from a utility processing center.

13. The device of claim 12, wherein the utility processing center comprises a billing center.

14. The device of claim 1, wherein the predetermined action comprises adjusting electricity usage in at least a portion of a building.

5. A communication unit in a wireless cellular communication system, the communication unit comprising:

a base station interface module receiving utility usage data from a utility usage-data collection device;

a network interface module in communication with a telephone network;

a switch matrix coupling the base station interface module and the network interface module; and

a processor responsive to the switch matrix and in communication with a utility processing center,

the utility processing center remotely instructing the utility usage-data collection device to transmit the utility usage data over a control channel of the wireless communication system, and the switch matrix routing the utility usage data to one of the network interface module and the processor.

6. The communication unit of claim 5, further comprising a memory storage device responsive to the processor and storing the utility usage data.

7. The communication unit of claim 6, wherein the utility usage data is transmitted from the memory storage device to the utility processing center.

8. A wireless communication system comprising:

a first communication unit;

a utility usage-data collection device having a plurality of modes of operation, the utility usage-data collection device responsive to the first communication unit and operable for transmitting utility usage data to the first communication unit over a control channel of the wireless communication system; and

a second communication unit coupled to the first communication unit, the second communication unit comprising;

a first communication unit interface module receiving the utility usage data from the first communication unit;

a network interface module in communication with a telephone network; and

a switch matrix coupling the first communication unit interface module and the network interface module.

9. The system of claim 8, wherein said first communication unit comprises a base station.

10. The system of claim 8, wherein said wireless communication system comprises a radiotelephone system.

11. The system of claim 8, wherein said wireless communication system is selected from the group consisting essentially of a frequency division multiple access system, a time division multiple access system, and a code division multiple access system.

15. A method for controlling a utility usage-data collection device, the utility usage-data collection device coupled to a utility meter and responsive to a wireless communication system, the wireless communication system in communication with a utility processing center, the method comprising the steps of:

receiving, by the utility usage-data collection device, a message over a control channel of the wireless communication system; and

based on the message, entering one of a plurality of modes of operation.

16. The method of claim 15, wherein the message is selected from the group consisting essentially of:

a telemetry poll message, an operations message and a control message.

17. The method of claim 16, wherein the one of the plurality of modes of operation is selected from the group consisting essentially of:

a polling mode, an operational support mode and a remote control mode.

18. The method of claim 15, further comprising the step of:

prior to receiving the message by the utility usage-data collection device, receiving, by the wireless communication system, a command from the utility processing center.

19. The method of claim 18, wherein the message is received by the utility usage-data collection device in response to the command.
