Abstract

A method is disclosed for delivering broadband video data to an end user device comprising transmitting broadband video data via a radio frequency transmitter to a home radio frequency receiver located at a residential power transformer providing electrical power to a home; coupling the broadband video data from the home radio frequency receiver to a first modem onto a copper power line electrically coupled to the residential power transformer; receiving the broadband data on a second modem from the copper power line; and sending from the second modem, different portions of the broadband data to each of a plurality of end user devices in the home. A system and computer program for performing the method are disclosed.

First claim

The invention claimed is:

1. A method, comprising:
receiving, by a processing system including a processor, video data via a millimeter-wave signal at a first radio frequency receiver located at a first power transformer that provides electrical power at a location, wherein the video data is obtained wirelessly by the first radio frequency receiver from a network node, wherein a power of the millimeter-wave signal is limited so that the millimeter wave signal interacts with a first antenna at the first power transformer while not interacting with a second antenna at a second power transformer, and wherein the millimeter-wave signal is generated by converting an optical digital data signal using a photodiode; and
transmitting, by the processing system, the video data by unicasting from the first power transformer to a modem at the location to deliver the video data to a plurality of end user devices at the location.

2. The method of claim 1 , wherein a first plurality of radio frequency signals received at the first radio frequency receiver are associated with a first local region and wherein a second plurality of radio frequency signals received by a second radio frequency receiver are associated a second local region.

3. The method of claim 2 , wherein the first plurality of radio frequency signals and the second plurality of radio frequency signals do not interfere with each other in their respective local regions.

4. The method of claim 1 , wherein the millimeter-wave signal includes amplitude information and phase information.

5. The method of claim 1 , wherein the millimeter-wave signal is demodulated by electro-optic sampling.

6. The method of claim 1 , wherein the video data is received as encrypted data, and wherein the encrypted data is decrypted by a first end user device of the plurality of end user devices.

7. The method of claim 1 , wherein the video data delivered to a first end user device of the plurality of end user devices is carried by a first frequency, wherein the video data delivered to a second end user device of the plurality of end user devices is carried by a second frequency, and wherein the first frequency differs from the second frequency.

8. The method of claim 1 , further comprising transmitting, by the processing system, the video data to a second modem at a second location via a power line extending between the power transformer and the second modem at the second location to enable the second modem to send different portions of the video data to each of a second plurality of end user devices in the second location.

9. The method of claim 1 , wherein the network node comprises a digital subscriber line access multiplexer.

10. A device, comprising:
a processing system including a processor; and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, comprising:
receiving video data via a millimeter-wave signal at a first radio frequency receiver located at a first power transformer that provides electrical power at a location, wherein a power of the millimeter-wave signal is limited so that the millimeter wave signal interacts with a first antenna at the first power transformer while not interacting with a second antenna at a second power transformer, and wherein the millimeter-wave signal is generated by converting an optical digital data signal using a photodiode; and
transmitting the video data by unicasting from the first power transformer to a modem at the location to deliver the video data to a plurality of end user devices at the location.

11. The device of claim 10 , wherein the video data is received as encrypted data, and wherein the encrypted data is decrypted by a first end user device of the plurality of end user devices.

12. The device of claim 10 , wherein the video data is obtained wirelessly by the first radio frequency receiver from a network node.

13. The device of claim 12 , wherein the network node comprises a digital subscriber line access multiplexer.

14. The device of claim 10 , wherein a first plurality of radio frequency signals received at the first radio frequency receiver are associated with a first local region and wherein a second plurality of radio frequency signals received by a second radio frequency receiver are associated a second local region.

15. The device of claim 14 , wherein the first plurality of radio frequency signals and the second plurality of radio frequency signals do not interfere with each other in their respective local regions.

16. The device of claim 10 , wherein the millimeter-wave signal includes amplitude information and phase information.

17. The device of claim 10 , wherein the millimeter-wave signal is demodulated by electro-optic sampling.

18. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, comprising:
receiving video data via a millimeter-wave signal at a first radio frequency receiver located at a first power transformer that provides electrical power at a location, wherein a power of the millimeter-wave signal is limited so that the millimeter wave signal interacts with a first antenna at the first power transformer while not interacting with a second antenna at a second power transformer, and wherein the millimeter-wave signal is generated by converting an optical digital data signal; and
transmitting the video data by unicasting from the first power transformer to a modem at the location to deliver the video data to a plurality of end user devices at the location.

19. The non-transitory machine-readable medium of claim 18 , wherein the millimeter-wave signal includes amplitude information and phase information, wherein the millimeter-wave signal is demodulated by electro-optic sampling.

20. The non-transitory machine-readable medium of claim 18 , wherein a first plurality of radio frequency signals received at the first radio frequency receiver are associated with a first local region and wherein a second plurality of radio frequency signals received by a second radio frequency receiver are associated a second local region, and wherein the first plurality of radio frequency signals and the second plurality of radio frequency signals do not interfere with each other in their respective local regions.
