Method and system for broadband near-field communication
View Patent ↗A first mobile consumer electronic device comprises a broadband near-field communications (BNC) transceiver and is configured to operate as a main processing unit for a second mobile consumer electronic device that is configured as a thin-client. The first mobile consumer electronic device may capture, via the BNC transceiver, a signal over a range of frequencies that spans multiple frequency bands which are licensed by a regulatory authority. The first mobile consumer electronic device may process the captured signal to determine which of the multiple frequency bands are not currently in use by other devices. The first mobile consumer electronic device may select a plurality of the frequency bands. The first mobile consumer electronic device may transmit, via the BNC transceiver, a signal over the selected plurality of frequency bands at a determined strength, where the signal carries video data destined for the second mobile consumer electronic device.
1. A method comprising:
in a first mobile consumer electronic device that comprises a broadband near-field communications (BNC) transceiver and is configured to operate as a main processing unit for a second mobile consumer electronic device that is configured as a thin-client:
capturing, via said BNC transceiver, one or more signals over multiple frequency bands which are licensed by a regulatory authority;
processing said captured one or more signals to determine which of said multiple frequency bands are not currently in use by other devices;
selecting a plurality of said frequency bands; and
transmitting, via said BNC transceiver, a signal over said selected plurality of frequency bands at a determined strength, wherein said signal carries video data destined for said second mobile consumer electronic device, wherein said video data is a graphical user interface of an application running on said first mobile electronic device, wherein a quantity of frequency bands selected during said selecting is based on a type of said application.
2. The method of claim 1 , comprising determining an aggregate bandwidth of said selected plurality of frequency bands.
3. The method of claim 2 , comprising determining said strength based on aggregate bandwidth.
4. The method of claim 1 , wherein said selected plurality of frequency bands include broadcast television frequency bands.
5. The method of claim 1 , wherein said determined strength is such that, for each one of said selected plurality of frequency bands, a power spectral density of said transmitted signal on said one of said selected plurality of frequency bands is 30 dB or more below a spurious emissions limit set for said one of said selected plurality of frequency bands by said regulatory authority.
6. The method of claim 1 , comprising receiving user input from said second mobile consumer electronic device via said BNC transceiver.
7. The method of claim 6 , comprising updating said video data in real time in response to said user input.
8. The method of claim 1 , comprising determining said strength based on security settings for said video data.
9. A system comprising:
a first mobile consumer electronic device that comprises a central processing unit (CPU) and a broadband near-field communications (BNC) transceiver, and is configured to operate as a main processing unit for a second mobile consumer electronic device that is configured as a thin-client, wherein said first mobile consumer electronic device is operable to:
capture, via said BNC transceiver, one or more signals over multiple frequency bands which are licensed by a regulatory authority;
process said captured one or more signals to determine which of said multiple frequency bands are not currently in use by other devices;
select a plurality of said frequency bands; and
transmit, via said BNC transceiver, a signal over said selected plurality of frequency bands at a determined strength, wherein said signal carries video data destined for said second mobile consumer electronic device, wherein said video data is a graphical user interface of an application running on said first mobile electronic device, wherein a quantity of frequency bands selected during said selecting is based on a type of said application.
10. The system of claim 9 , wherein said first mobile consumer electronic device is operable to determine an aggregate bandwidth of said selected plurality of frequency bands.
11. The system of claim 10 , wherein said first mobile consumer electronic device is operable to determine said strength based on aggregate bandwidth.
12. The system of claim 9 , wherein said selected plurality of frequency bands include broadcast television frequency bands.
13. The system of claim 9 , wherein said determined strength is such that, for each one of said selected plurality of frequency bands, a power spectral density of said transmitted signal on said one of said selected plurality of frequency bands is 30 dB or more below a spurious emissions limit set for said one of said selected plurality of frequency bands by said regulatory authority.
14. The system of claim 9 , wherein said first mobile consumer electronic device is operable to receive user input from said second mobile consumer electronic device via said BNC transceiver.
15. The system of claim 14 , wherein said first mobile consumer electronic device is operable to update said video data in real time in response to said user input.
16. The system of claim 9 , wherein said first mobile consumer electronic device is operable to determine said strength based on security settings for said video data.
