Abstract

In embodiments of the present invention improved capabilities are described for a system of information RFID tagging facilities comprising a first radio frequency (RF) tag and a second RF tag, wherein the first RF tag and the second RF tag are adapted to at least in part operate using energy received from an RF signal, wherein the first RF tag receives energy from a first RF signal from an RF device and the second RF tag is out of range of the first RF signal from the RF device, wherein the first RF tag and the second RF tag are adapted to exchange data.

Claims

1. A system, comprising:

a first radio frequency (RF) tag and a second RF tag, wherein the first RF tag and the second RF tag are adapted to at least in part operate using energy received from an RF signal, wherein the first RF tag and the second RF tag transfer data between each other when (i) the first RF tag receives energy from a first RF signal from an RF device and (ii) the second RF tag is out of range of the first RF signal from the RF device.

2. The system of claim 1, wherein the second RF tag operates at least in part using energy received from a second RF signal from the first RF tag.

3. The system of claim 2, wherein the first RF tag and the second RF tag are passive RF tags with no other power source other than the energy received from an RF signal.

4. The system of claim 1, wherein data is further transferred between the RF device and at least one of the first RF tag and the second RF tag.

5. The system of claim 1, wherein the exchange of data is through a network protocol.

6. The system of claim 1, wherein the RF device is a third RF tag at least in part powered by an external energy source.

7. The system of claim 6, wherein the external energy source is a battery.

8. The system of claim 6, wherein the external energy source is solar energy.

9. The system of claim 6, wherein the external energy source is one of vibrational energy and energy arising from a piezoelectric effect.

10. The system of claim 1, wherein the first RF tag and the second RF tag are mounted on separate substrates and packaged as physically separate devices.

11. A system, comprising:

a first radio frequency (RF) tag and a second RF tag, wherein the first RF tag and the second RF tag are adapted to at least in part operate using energy received from an RF signal, wherein the first RF tag and the second RF tag are adapted to exchange data when (i) the first RF tag receives energy from a first RF signal from an RF device and (ii) the second RF tag is out of range of the first RF signal from the RF device.

12. The system of claim 11, wherein the second RF tag operates using energy received from a second RF signal from the first RF tag.

13. The system of claim 11, wherein the exchange of data is through a network protocol.

14. The system of claim 11, wherein the first RF tag and the second RF tag are mounted on separate substrates and packaged as physically separate devices.

15. A system, comprising:

a first radio frequency (RF) tag and a second RF tag, wherein the first RF tag and the second RF tag are adapted to at least in part operate using energy received from an RF signal, wherein the first RF tag operates using energy received from a first RF signal from an RF device and the second RF tag operates using energy received from a second RF signal from the first RF tag, and data is exchanged between the first RF tag and the second RF tag.

16. The system of claim 15, wherein the first RF tag and the second RF tag are passive RF tags with no other power source other than the energy received from an RF signal.

17. The system of claim 15, wherein the data transferred is exchanged directly between the first RF tag and the second RF tag without being relayed through the RF device.

18. The system of claim 15, wherein data is further transferred between the RF device and at least one of the first RF tag and the second RF tag.

19. The system of claim 15, wherein the exchange of data is through a network protocol.

20. The system of claim 15, wherein the RF device is a third RF tag powered by an external energy source.
