Abstract

A method for enabling a device executing a processing module to enable simultaneous operations in multiple frequency bands. The method includes sensing a set of one or more vacant channels, determining availability of particular spectrum channels in the one or more vacant channels, reserving one or more particular spectrum channels from the one or more vacant channels and configuring the device for the one or more particular spectrum channels for communication.

Claims

1. A method performed by a device programmed by a processing module for enabling a device for simultaneous operations in multiple frequency bands comprising:

sensing one or more vacant channels;

determining availability of a set of spectrum channels in the one or more vacant channels;

reserving one or more particular spectrum channels from the one or more vacant channels; and

configuring the device to use the one or more particular spectrum channels for communication.

2. The method of claim 1 further comprising choosing an optimal combination of one or more of bands, frequency channels, and communication modes for the broadband communication.

3. The method of claim 1, wherein reserving the one or more sufficient spectrum channels enables avoiding other devices to occupy the one or more sufficient spectrum channels.

4. The method of claim 1 further comprising minimizing self interference of the device during operation in the multiple frequency bands.

5. The method of claim 1, wherein the one or more vacant channels comprises white space spectrum.

6. The method of claim 1, wherein the device includes at least one member of a group comprising:

a computing device, a portable computing device, a desktop computer, a laptop computer, a palm sized computer, a pocket-sized computer, a personal computer memory card international association (PCMCIA) card or PC card, a cellular telephone, a personal data assistant (PDA), a personal information manager (PIM), a wireless access point (WAP), a base station, a base station transceiver, a microelectronic circuit, and a circuit board.

7. The method of claim 1 further comprising advertising of the device using a beacon channel to negotiate spectrum and specification requirements.

8. The method of claim 1 further comprising elaborating on Medium Access Control (MAC) protocols for coordinating the usage of multiple frequency bands simultaneously.

9. A computer program executed on a processor to perform the method of claim 1.

10. The method of claim 1 wherein the set of spectrum channels comprises at least one of television bands, cellular bands, am radio bands, and fm radio bands.

11. A device capable of simultaneous operations in multiple frequency bands comprising:

a sensor for sensing one or more vacant channels;

a processing module for determining availability of a set of spectrum channels in the one or more vacant channels for broadband communication;

a communication module for reserving one or more particular spectrum channels; and

a configuration module for reprogramming the device for the one or more particular spectrum channels for communication.

12. The device of claim 11, wherein the one or more vacant channels comprises white space spectrum.

13. The device of claim 11, wherein the communication module further reserves the one or more sufficient spectrum channels to avoid other devices occupying the one or more sufficient spectrum channels.

14. The device of claim 11, wherein the device is one of a group comprising:

a computing device, a portable computing device, a desktop computer, a laptop computer, a palm sized computer, a pocket-sized computer, a personal computer memory card international association (PCMCIA) card or PC card, a cellular telephone, a personal data assistant (PDA), a personal information manager (PIM), a wireless access point (WAP), a base station, a base station transceiver, a microelectronic circuit, and a circuit board.

15. The device of claim 11 wherein the set of spectrum channels comprises at least one of television bands, cellular bands, am radio bands, and fm radio bands.

16. A device capable of simultaneous operations in multiple frequency bands comprising:

means for sensing one or more vacant channels;

means for determining availability of one or more particular spectrum channels in the one or more vacant channels for broadband communication;

means for reserving the one or more particular spectrum channels; and

means for reprogramming the device for the one or more particular spectrum channels for communication.

17. The device of claim 16, wherein the one or more vacant channels comprises white space spectrum.

18. The device of claim 16 further comprising reserving the one or more particular spectrum channels to avoid other devices occupying the one or more particular spectrum channels.

19. The device of claim 16, wherein the first device and second device are one of a group comprising:

a computing device, a portable computing device, a desktop computer, a laptop computer, a palm sized computer, a pocket-sized computer, a personal computer memory card international association (PCMCIA) card or PC card, a cellular telephone, a personal data assistant (PDA), a personal information manager (PIM), a wireless access point (WAP), a base station, a base station transceiver, a microelectronic circuit, and a circuit board.
