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

in a first wireless communication device;

establishing an ad-hoc communication link with a second wireless communication device within operating range; and

sharing a replica of at least a portion of a display of said first wireless communication device with said second wireless communication device utilizing wireless broadband signals that are communicated via said established ad-hoc communication link, wherein;

said first wireless communication device is operable to communicate said wireless broadband signals at a power level that is below a spurious emissions mask; and

said transmitted wireless broadband signals occupy a designated frequency spectrum band.

2. The method according to claim 1, comprising:

spreading said wireless broadband signals having said power level that is below said spurious emissions mask across said entire designated frequency spectrum band, wherein;

a bandwidth of said wireless broadband signals occupy approximately 800 MHz within a range of 0 Hz to 1 GHz;

a corresponding transmit power utilized for said transmitting of said wireless broadband signals is spread over a bandwidth of approximately 300 MHz within said 800 MHz bandwidth; and

said spreading results in a power spectral density of said transmitted wireless broadband signals approximating thermal noise at a distance of approximately 3 meters

3. The method according to claim 1, wherein said shared replica of said at least a portion of said display of said first wireless communication device comprises one or more applications, text, video and/or data content.

4. The method according to claim 1, comprising interacting with content that is displayed on a display of said second wireless communication device.

5. The method according to claim 4, determining whether to utilize security for one or both of said sharing and/or said interaction.

6. The method according to claim 4, wherein said security is based on one or both of proximity of said first wireless communication device to said second wireless communication device and/or one or more corresponding profiles associated with said first wireless communication device and said second wireless communication device.

7. The method according to claim 1, wherein:

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

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

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

9. The method according to claim 8 wherein said sharing of said replica of said at least said portion of said display of said first wireless communication device and said sharing by said second wireless communication device occurs concurrently.
