Abstract

The present method enables an RFID repeater to be used in conjunction with an RFID tag to allow data in the RFID tag to be read using wireless packet switched technologies. For example, the present method enables an RFID repeater to be coupled with an RFID tag. The RFID repeater reads and records the data from the RFID tag and then transmits the retrieved data from the RFID tag over a wireless packet network.

Claims

1. A method for communicating with a radio frequency identification tag, the method comprising:

retrieving data from the radio frequency identification tag by a radio frequency identification repeater, wherein the radio frequency identification repeater is coupled to the radio frequency identification tag, wherein the retrieving comprises;

reading the data by a radio frequency identification reader residing in the radio frequency identification repeater; and

storing the data in a memory residing in the radio frequency identification repeater; and

communicating the data that is retrieved from the radio frequency identification tag by the radio frequency identification repeater to a server via a wireless packet switched network.

2. The method of claim 1, wherein the wireless packet switched network employs at least one of:

a wireless fidelity protocol, an ultra wideband protocol, a cellular protocol, or a Zigbee®

protocol.

3. The method of claim 1, wherein the data that is retrieved is read via a pair of antennae between the radio frequency identification repeater and the radio frequency identification tag.

4. The method of claim 1, wherein the reading of the data from the radio frequency identification tag by the radio frequency identification reader is commanded remotely to refresh the data stored in the memory of the radio frequency identification repeater.

5. The method of claim 1, wherein the radio frequency identification tag comprises an active radio frequency identification tag or a passive radio frequency identification tag.

6. The method of claim 1, wherein the communicating comprises:

sending the data that is retrieved to the server via a wireless access point or a base station that provides a connectivity to the server.

7. The method of claim 6, wherein the connectivity comprises a wired local area network or a wireless local area network.

8. A communication system, comprising:

a radio frequency identification tag; and

a radio frequency identification repeater for retrieving data from the radio frequency identification tag, wherein the radio frequency identification repeater is coupled to the radio frequency identification tag, wherein the radio frequency identification repeater is for communicating the data that is retrieved from the radio frequency identification tag to a server via a wireless packet switched network, wherein the radio frequency identification repeater comprises a radio frequency identification reader for reading the data from the radio frequency identification tag, and wherein the data is stored in a memory residing in the radio frequency identification repeater.

9. The communication system of claim 8, wherein the wireless packet switched network employs at least one of:

a wireless fidelity protocol, an ultra wideband protocol, a cellular protocol, or a Zigbee®

protocol.

10. The communication system of claim 8, wherein the data that is retrieved is read via an antenna disposed on the radio frequency identification repeater and an antenna disposed on the radio frequency identification tag.

11. The communication system of claim 8, wherein the retrieving of the data from the radio frequency identification tag by the radio frequency identification reader is commanded remotely to refresh the data stored in the memory of the radio frequency identification repeater.

12. The communication system of claim 8, wherein the radio frequency identification tag comprises an active radio frequency identification tag or a passive radio frequency identification tag.

13. The communication system of claim 8, wherein the radio frequency identification repeater communicates the data that is retrieved by sending the data that is retrieved to the server via a wireless access point or a base station that provides a connectivity to the server.

14. The communication system of claim 13, wherein the connectivity comprises a wired local area network or a wireless local area network.

15. A tangible computer-readable medium storing instructions which, when executed by a processor of a radio frequency identification repeater, cause the processor to perform operations for communicating with a radio frequency identification tag, the operations comprising:

retrieving data from the radio frequency identification tag by the radio frequency identification repeater, wherein the radio frequency identification repeater is coupled to the radio frequency identification tag, wherein the retrieving comprises;

reading the data by a radio frequency identification reader residing in the radio frequency identification repeater; and

storing the data in a memory residing in the radio frequency identification repeater; and

communicating the data that is retrieved from the radio frequency identification tag by the radio frequency identification repeater to a server via a wireless packet switched network.

16. The tangible computer-readable medium of claim 15, wherein the wireless packet switched network employs at least one of:

a wireless fidelity protocol, an ultra wideband protocol, a cellular protocol, or a Zigbee®

protocol.

17. The tangible computer-readable medium of claim 15, wherein the data that is retrieved is read via a pair of antennae between the radio frequency identification repeater and the radio frequency identification tag.

18. The tangible computer-readable medium of claim 15, wherein the reading of the data from the radio frequency identification tag by the radio frequency identification reader is commanded remotely to refresh the data stored in the memory of the radio frequency identification repeater.

19. The tangible computer-readable medium of claim 15, wherein the radio frequency identification tag comprises an active radio frequency identification tag or a passive radio frequency identification tag.

20. The tangible computer-readable medium of claim 15, wherein the communicating comprises:

sending the data that is retrieved to the server via a wireless access point or a base station that provides a connectivity to the server.
