Abstract

An embodiment of the present invention provides a method of spectrum use authorization, comprising using a certificated declaration of spectrum licensed by licensed users of said spectrum to authenticate said users. The certificated declaration may provide information on transmitter location, channels occupied and an interference footprint or profile and allow a recipient of such information to determine that an occupied channel is genuinely occupied by a licensed user. The certificated declaration also may allow an unlicensed device to build and maintain a list of incumbent users and allows an unlicensed device to compare location and interference contour data against its own location and transmitter power to determine if it will interfere. Further, it may allow a license holder to distribute information about its presence out of band of the signal to be protected and a license holder to distribute information about its presence over a predetermined geographic area. The certificate may be a standard X.509 certificate with additional fields. An embodiment of the present invention further may comprise transmitting the certificated declaration in band with a licensee'"'"'s transmissions and may aggregating said certificated declarations by equipment manufacturers and placing them in equipment to be used in said spectrum or making said certificated declarations available over the internet enabling unlicensed equipment to access licensee information from sources other than the licensed transmitter. An embodiment of the present invention also provides an apparatus, comprising a transceiver capable of using a certificated declaration of spectrum licensed to authenticate users of said spectrum.

Claims

1. A method of spectrum use authorization, comprising:

using a certificated declaration of spectrum licensed by licensed users of said spectrum to authenticate said users.

2. The method of claim 1, further comprising including in said certificates information on transmitter location, channels occupied and an interference footprint or profile.

3. The method of claim 2, wherein said certificate allows a recipient of such information to determine that an occupied channel is genuinely occupied by a licensed user.

4. The method of claim 2, wherein said certificate allows an unlicensed device to build and maintain a list of incumbent users.

5. The method of claim 2, wherein said certificate allows an unlicensed device to compare location and interference contour data against its own location and transmitter power to determine if it will interfere.

6. The method of claim 2, wherein said certificate allows a license holder to distribute information about its presence out of band of the signal to be protected and a license holder to distribute information about its presence over a predetermined geographic area.

7. The method of claim 1, wherein said certificate is a standard X.509 certificate with additional fields.

8. The method of claim 1, further comprising transmitting said certificated declaration in band with a licensee'"'"'s transmissions.

9. The method of claim 1, further comprising aggregating said certificated declarations and placing them in equipment to be used in said spectrum.

10. The method of claim 1, further comprising making said certificated declarations available over the internet or other data networks enabling unlicensed equipment to access licensee information from sources other than the licensed transmitter.

16. The apparatus of claim 2, wherein said certificate allows a license holder to distribute information about its presence out of band of the signal to be protected and a license holder to distribute information about its presence over a predetermined geographic area.

17. The apparatus of claim 1, wherein said certificate is a standard X.509 certificate with additional fields.

11. An apparatus, comprising:

a transceiver capable of using a certificated declaration of spectrum licensed to authenticate users of said spectrum.

12. The apparatus of claim 11, wherein said certificates contain information on transmitter location, channels occupied and an interference footprint or profile.

13. The apparatus of claim 12, wherein said certificate allows a recipient of such information to determine that an occupied channel is genuinely occupied by a licensed user.

14. The apparatus of claim 12, wherein said certificate allows an unlicensed device to build and maintain a list of licensed incumbent users of spectrum.

15. The apparatus of claim 12, wherein said certificate allows an unlicensed device to compare location and interference contour data against its own location and transmitter power to determine if it will interfere.

18. The apparatus of claim 11, wherein said transceiver is capable of transmitting said certificated declaration in band with a licensee'"'"'s transmissions.

19. The apparatus of claim 11, wherein said certificated declarations are aggregated and placed in equipment to be used in said spectrum.

20. The apparatus of claim 11, wherein said certificated declarations available over the internet enabling unlicensed equipment to access licensee information from sources other than the licensed transmitter.

21. An article, comprising:

a storage medium having stored thereon instructions, that, when executed by a computing platform results in;

using a certificated declaration of spectrum licensed by licensed users of said spectrum to authenticate said users.

22. The article of claim 21, further comprising including in said certificates information on transmitter location, channels occupied and an interference footprint or profile.

23. The article of claim 22, wherein said certificate allows a recipient of such information to determine that an occupied channel is genuinely occupied by a licensed user.

24. The article of claim 22, wherein said certificate allows an unlicensed device to build and maintain a list of incumbent users.

25. The article of claim 22, wherein said certificate allows an unlicensed device to compare location and interference contour data against its own location and transmitter power to determine if it will interfere.

26. The article of claim 22, wherein said certificate allows a license holder to distribute information about its presence out of band of the signal to be protected and a license holder to distribute information about its presence over a predetermined geographic area.

27. A wireless communication system, comprising:

a predetermined wireless spectrum capable of being utilized for wireless communication between a plurality of wireless devices; and

a certificated declaration capable of being used by users of said wireless spectrum to determine which users are licensed to use said wireless spectrum.

28. The system of claim 28, wherein said certificated declaration contains information on transmitter location, channels occupied and an interference footprint or profile.

29. The system of claim 28, wherein said certificated declaration allows an unlicensed device to build and maintain a list of incumbent users.

30. The system of claim 28, wherein said certificated declarations are aggregated by equipment manufacturers and placed in equipment to be used in said spectrum.
