Abstract

A wireless communication device (WCD) establishes an ad-hoc communication link with a second WCD within operating range. A replica of at least a portion of a display of the first WCD may be shared with the second WCD utilizing wireless broadband signals that are communicated via the established one or more ad-hoc communication links. The first WCD and the second WCD are operable to communicate the wireless broadband signals at a power level that is below a spurious emissions mask. The transmitted wireless broadband signals are spread so they occupy a designated frequency spectrum band. The shared replica of at least a portion of the display of the first WCD includes one or more applications, text, video and/or data content. A user of the first WCD may interact with content that is displayed on a display of the second WCD and vice-versa.

Claims

1. A method, comprising:

in a first wireless communication device;

establishing an ad-hoc communication link with a second wireless communication device;

selecting a security level from a plurality of different security levels according to an estimated distance between the first wireless communication device and the second wireless communication device; and

sharing a replica of a portion of a display in the first wireless communication device with the second wireless communication device utilizing the established ad-hoc communication link and the selected security level.

2. The method according to claim 1, wherein the replica of the portion of the display of the first wireless communication device comprises one or more applications, text, video and/or data content.

3. The method according to claim 1, comprising interacting with content on a display of the second wireless communication device.

4. The method according to claim 3, comprising determining whether to utilize the selected security level for the interaction.

5. The method according to claim 3, wherein the selected security level is based on a profile associated with the first wireless communication device and the second wireless communication device.

6. The method according to claim 1, wherein:

the second wireless communication device establishes a new ad-hoc communication link with a third wireless communication device; and

the second wireless communication device is operable to communicate, at a power level that is below a spurious emissions mask, with the third wireless communication device utilizing a third wireless signal via the established new ad-hoc communication link.

7. The method according to claim 6, wherein the second wireless communication device shares a replica of a portion of a display of the second wireless communication device with the third wireless communication device via the established new ad-hoc communication link.

8. The method according to claim 7, wherein the sharing of the replica of the portion of the display of the first wireless communication device and the sharing of the replica of the portion of the display of the second wireless communication device occurs concurrently.

9. The method according to claim 1, wherein the established ad-hoc communication link comprises a bi-directional communication link.

10. The method according to claim 1, comprising utilizing the first wireless signal to power the transmitting of the second wireless signal.

11. A system in a first wireless communication device, comprising:

a receiver operable to receive a first wireless signal from a second wireless communication device; and

a processor operable to;

establish an ad-hoc communication link with the second wireless communication device;

select a security level from a plurality of different security levels according to an estimated distance between the first wireless communication device and the second wireless communication device; and

share a replica of a portion of a display in the first wireless communication device with the second wireless communication device utilizing the established ad-hoc communication link and the selected security level.

12. The system according to claim 11, wherein the shared replica of a portion of the display of the first wireless communication device comprises one or more applications, text, video and/or data content.

13. The system according to claim 11, wherein the processor is operable to enable interaction with content on a display of the second wireless communication device.

14. The system according to claim 13, wherein the processor is operable to determine whether to utilize the selected security level for the interaction.

15. The system according to claim 13, wherein the selected security level is based on a profile associated with the first wireless communication device and the second wireless communication device.

16. The system according to claim 11, wherein:

the second wireless communication device is operable to establish a new ad-hoc communication link with a third wireless communication device; and

the second wireless communication device is operable to communicate, at a power level that is below the spurious emissions mask, with the third wireless communication device utilizing a third wireless signal via the established new ad-hoc communication link.

17. The system according to claim 16, wherein the second wireless communication device shares a replica of a portion of a display of the second wireless communication device with the third wireless communication device via the established new ad-hoc communication link.

18. The system according to claim 17, wherein the sharing of the replica of the at least the portion of the display of the first wireless communication device and the sharing of the replica of the portion of the display of the second wireless communication device concurrently.

19. The system according to claim 11, wherein the established ad-hoc communication link comprises a bi-directional communication link.

20. The system according to claim 11, wherein the system comprises a transmitter operable to produce a spread signal at a power level that is below a spurious emissions mask across a designated frequency spectrum band, wherein a power spectral density of the spread signal is near a power spectral density of thermal noise at a distance of approximately 3 meters.
