Abstract

A communication network and method, including an information signal line which carries a plurality of selectable information signals. Electrical lines run throughout a building, with electrical outlets connected to the electrical line. An electrical line distribution panel connects the information signal line and the electrical line for distributing the selectable information signals over the electrical line to the location of a given electrical outlet. Dielectric-core couplers which are impedance-matched with the electrical line are connected to the electrical outlets. At least one communication station is connected to a dielectric-core coupler for receiving the selectable information signals.

Claims

1. A communication network comprising:

an information signal line carrying a plurality of selectable information signals;

electrical line wired through a building;

electrical outlets connected to said electrical line;

an electrical line distribution panel connected to said information signal line and said electrical line for distributing said information signals over said electrical line to said electrical outlets in response to a selection signal;

at least one dielectric core coupler impedance matched with said electrical line connected to said electrical outlets; and

at least one communication station connected to said at least one dielectric core coupler for sending said selection signal and receiving said selectable information signals.

2. The communication network of claim 1 wherein said distribution panel is adapted to receive a selection signal from said at least one communication station to select one of said selectable information signals for transmission over said electrical line to said at least one communication station.

3. The communication network of claim 1 wherein said selectable information signals are distributed over said electrical line at a rate of substantially 6 Mbps.

4. The communication network of claim 1 wherein said information signal line is a coaxial cable.

5. The communication network of claim 1 wherein said information signal line is a fiber optic cable.

6. The communication network of claim 1 wherein said information signal line is a twisted pair telephone line.

7. The communication network of claim 1 wherein said electrical line is an AC electrical wire.

8. The communication network of claim 1 wherein said communication station is a cable television tuner.

9. The communication network of claim 1 wherein said communication station is a computer with an attached modem.

10. The communication network of claim 1 wherein said commmunication station is a telephone device.

11. The communication network of claim 1 wherein said

distribution panel comprises a circuit breaker box or fuse box.

12. The communication network of claim 1 wherein said distribution panel comprises a transceiver adapted to distribute up to 14 separate selectable information signals throughout said building.

13. The communication network of claim 1 wherein said at least one dielectric core coupler is an air core coupler.

14. A method of receiving, over an electrical line, selectable information signals carried on an information signal line comprising the steps of:

sending a selection signal corresponding to one of said selectable information signals through a dielectric core coupler impedance matched with said electrical line;

receiving said selection signal at a distribution panel connected to said information signal line;

interpreting said selection signal and sending said selectable information signal corresponding to said selection signal over said electrical line and through said dielectric core coupler to a receiving station.
