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:

establishing, in a first wireless communication device, a first ad-hoc communication link with a second wireless communication device within operating range, wherein the establishing the ad-hoc communication link comprises the first communication device;

determining, based on strength of wireless broadband signals received by the first wireless communication device from the second wireless communication device, a distance between the first wireless communication device and the second wireless communication device;

exchanging security information with the second wireless communication device if the determined distance between the first wireless communication device and the second wireless communication device is above a first threshold; and

bypassing an exchange of the security information if the determined distance between the first wireless communication device and the second wireless communication device is below the first threshold; and

sharing, by the first wireless communication device using wireless broadband signals communicated via the first ad-hoc communication link, application data with the second wireless communication device.

2. The method according to claim 1, wherein the security information is based on one or more profiles associated with the first wireless communication device and the second wireless communication device.

3. The method according to claim 1, comprising establishing, by the second wireless communication device, a second ad-hoc communication link with a third wireless communication device.

4. The method according to claim 3, comprising sharing, by the second wireless communication device using the second ad-hoc communication link, the application data.

5. The method according to claim 4, wherein the sharing of the application data via the first ad-hoc communication link and the second ad-hoc communication link occurs concurrently.

6. The method according to claim 1, wherein the threshold corresponds to physical contact between the first wireless communication device and the second wireless communication device.

7. The method according to claim 1, wherein:

the security information is information that corresponds to a first level of security if the determined distance is above the first threshold and below a second threshold; and

the security information is information that corresponds to a second level of security if the determined distance is above the first threshold and above the second threshold.

8. The system according to claim 1, wherein the threshold corresponds to physical contact between the first wireless communication device and the second wireless communication device.

9. A system, comprising:

one or more circuits for use in a first wireless communication device, the one or more circuits being operable to;

establish a first ad-hoc communication link with a second wireless communication device within operating range, wherein the establishment of the first ad-hoc communication link comprises;

determination, based on strength of wireless broadband signals received by the first wireless communication device from the second wireless communication device, of a distance between the first wireless communication device and the second wireless communication device;

exchange of security information if the determined distance between the first wireless communication device and the second wireless communication device is above a first threshold; and

bypass of an exchange of the security information if the determined distance between the first wireless communication device and the second wireless communication device is below the first threshold; and

share, using wireless broadband signals communicated via the first ad-hoc communication link, application data with the second wireless communication device.

10. The system according to claim 9, wherein the security is based on one or more profiles associated with the first wireless communication device and the second wireless communication device.

11. The system according to claim 9, wherein the second wireless communication device comprises circuitry operable to establish a second ad-hoc communication link with a third wireless communication device.

12. The system according to claim 11, wherein the circuitry of the second wireless communication device is to share, via the second ad-hoc communication link, the application data.

13. The system according to claim 12, wherein the sharing of the application data via the first ad-hoc communication link and the second ad-hoc communication link occurs concurrently.

14. The system according to claim 9, wherein:

the security information is information that corresponds to a first level of security if the determined distance is above the first threshold and below a second threshold; and

the security information is information that corresponds to a second level of security if the determined distance is above the first threshold and above the second threshold.
