Abstract

A radio frequency identification system (20) generally includes at least one container (22), a radio frequency identification tag (24) capable of transmitting a radio frequency signal associated with the container, and a radio frequency device, such as a repeater (26) associated with the radio frequency identification tag or the container for enhancing readability of the radio frequency signal.

Claims

1. A combination container and radio frequency identification system, comprising:

(a) at least one container having a container body;

(b) a radio frequency identification tag associated with the at least one container body, wherein the radio frequency identification tag is capable of transmitting a radio frequency signal; and

(c) at least one discrete radio frequency device associated with the radio frequency identification tag or the at least one container body for enhancing readability of the radio frequency signal.

2. The system of claim 1, wherein the at least one discrete radio frequency device is a radio frequency signal repeater.

3. The system of claim 2, wherein the radio frequency signal repeater is an active repeater.

4. The system of claim 2, wherein the radio frequency signal repeater is a passive repeater.

5. The system of claim 2, wherein the location of the radio frequency signal repeater is selected from the group consisting of:

inside the at least one container body, on the external surface of the at least one container body, on the external surface of the at least one container body, remote of the at least one container body, inside the at least one container body, and within spacing material associated with the at least one container body.

6. The system of claim 3, wherein the active repeater enhances the readability of the radio frequency signal from the radio frequency reader by receiving a signal transmitted from the reader, amplifying the signal, and retransmitting the signal in the direction of the radio frequency identification tag.

7. The system of claim 3, wherein the active repeater enhances the readability of the radio frequency signal from the radio frequency reader by receiving a signal transmitted from the radio frequency identification tag, amplifying the signal, and retransmitting the signal in the direction of the reader.

8. The system of claim 4, wherein the passive repeater enhances the readability of the radio frequency signal from the radio frequency reader by receiving a signal transmitted from the reader, and reradiating the signal in the direction of the radio frequency identification tag.

9. The system of claim 4, wherein the passive repeater enhances the readability of the radio frequency signal from the radio frequency reader by receiving a signal transmitted from the radio frequency identification tag, and reradiating the signal in the direction of the reader.

10. The system of claim 1, wherein the at least one discrete radio frequency device is a plurality of radio frequency signal repeaters.

11. The system of claim 1, wherein the at least one container is selected from the group consisting of a box and a pallet supporting a plurality of boxes.

12. The system of claim 1, wherein the at least one container is a plurality of containers.

13. The system of claim 1, wherein the at least one discrete radio frequency device is spacing material associated with the container.

14. The system of claim 1, wherein the spacing material is corrugated linerboard.

15. The system of claim 1, wherein the at least one discrete radio frequency device is a repeater associated with spacing material.

16. A method of increasing readability of a radio frequency identification tag, comprising:

(a) obtaining a container;

(b) associating at least one radio frequency identification tag with the container, wherein the at least one radio frequency identification tag is capable of transmitting a radio frequency signal; and

(c) associating at least one radio frequency device with the radio frequency identification tag or the container, wherein the at least one radio frequency device enhances readability of the radio frequency signal.

17. In a combination container and radio frequency identification system of the type including a container having a radio frequency identification tag capable of transmitting a radio frequency response signal, and a radio frequency reader capable of transmitting a radio frequency interrogation signal, a method of increasing readability of the radio frequency identification tag by the radio frequency reader, comprising:

(a) receiving the interrogation signal transmitted from the reader or receiving the response signal transmitted from the radio frequency identification tag; and

(b) enhancing the received interrogation signal to enable readability by the radio frequency identification tag or enhancing the received response signal to enable readability by the reader.

19. The method of claim 19, wherein enhancing includes retransmitting or reradiating.

18. The method of claim 19, wherein enhancing includes amplifying.

20. The method of claim 19, wherein enhancing includes minimizing interference.
