Data communication over a power line
View Patent ↗A signal is received from a first portion of a power line and at least a portion of the signal is converted to a non-electrically conducting signal. The non-electrically conducting signal may be communicated to a non-electrically conductive communication path. In this manner, the non-electrically conducting signal may have properties that do not provide imminent danger from human contact.
1. A communication device for communicating data over a power line having a voltage greater than one thousand volts, comprising:
a data signal impedance coupled to the power line;
a data coupler comprising a first port and a second port wherein said first port is coupled to the power line on a first side of the data signal impedance and the second port of said coupler is coupled to the power line on the second side of the data signal impedance;
a modem communicatively coupled to said coupler;
a fiber optic transceiver communicatively coupled to said modem; and
a fiber optic cable communicatively coupled to said transceiver.
2. The device of claim 1 , further comprising a router in communication with said modem.
3. The device of claim 2 , wherein said router is configured to monitor usage data.
4. The device of claim 1 , further comprising an inductive power coupler configured to inductively couple power from the power signal carried by the power line.
5. The device of claim 4 , wherein said power coupler is electrically connected to said modem to provide power thereto.
6. The device of claim 5 , wherein said power coupler is electrically connected to said transceiver to provide power thereto.
7. The device of claim 6 , wherein said power coupler is connected to said modem through an AC-DC converter.
8. The device of claim 4 , wherein said power coupler is comprised of a magnetically permeable material having an aperture through which the power line may traverse.
9. The device of 8 , wherein said power coupler comprises a toroid.
10. The device of claim 8 , wherein said power coupler further comprises a first portion coupled to a second portion via a hinge.
11. The device of claim 1 , wherein said data coupler is an inductive coupler.
12. The device of claim 11 , wherein said inductive data coupler is comprised of a magnetically permeable material having an aperture through which the power line may traverse.
13. The device of claim 11 , wherein said inductive data coupler comprises a toroid.
14. The device of claim 13 , wherein said inductive coupler comprises a first portion coupled to a second portion via a hinge.
15. The device of claim 1 , wherein said data coupler is a capacitive coupler.
16. The device of claim 1 , wherein said modem is configured to communicate over the power line via a wideband signal.
17. The device of claim 16 , wherein said wideband signal comprises at least one carrier frequency of about fifty megahertz.
18. The device of claim 16 , wherein said wideband signal comprises an orthogonal frequency division multiplex (OFDM) signal.
