Abstract

An electrical apparatus which is configured with an antenna, transceiver, or repeater for transmission or reception over a wireless interface. In one embodiment, the appliance interfaces to a user device through a system which includes the power distribution system of the apparatus. In another embodiment, the apparatus, optionally in combination with a user device, forms a node of a wireless communication system.

Claims

1. A light bulb configured to provide a wireless interface for a user device, said user device being connected to said light bulb via a power line capable of carrying a data signal superimposed upon a power signal, said light bulb comprising:

a bulb;

a filament within said bulb, wherein said filament is coupled to said power line, and wherein said filament is illuminated by said power signal;

an antenna coupled to said power line; and

a contact for connecting said power line to said filament and said antenna;

wherein said antenna receives a user data signal from said user device via said power line, and wherein said antenna transmits said user data signal wirelessly.

2. The light bulb of claim 1, wherein said antenna is within said bulb.

3. The light bulb of claim 1, wherein said antenna is outside of said bulb.

4. The light bulb of claim 1 further comprising a transceiver, wherein said user data signal is a baseband signal, and wherein said transceiver modulates said baseband signal prior to transmission by said antenna.

5. The light bulb of claim 1, wherein said light bulb receives a remote data signal wirelessly from a remote device and transmits said remote data signal superimposed upon said power signal to said user device via said power line.

6. The light bulb of claim 5 further comprising a transceiver, wherein said remote data signal is a baseband signal, and wherein said transceiver demodulates said baseband signal after wireless reception of said remote data signal by said antenna.

7. The light bulb of claim 1, wherein said user data signal is a modulated signal.

8. A light bulb configured to provide a wireless interface for a user device, said user device being connected to said light bulb via a power line capable of carrying a data signal superimposed upon a power signal, said light bulb comprising:

a bulb;

a filament within said bulb, wherein said filament is coupled to said power line, and wherein said filament is illuminated by said power signal;

a repeater coupled to said power line; and

a contact for connecting said power line to said filament;

wherein said repeater receives a user data signal, and wherein said repeater transmits said user data signal wirelessly.

9. The light bulb of claim 8, wherein said repeater is within said bulb.

10. The light bulb of claim 8, wherein said repeater is outside of said bulb.

11. An electrical apparatus adapted to connect to a light bulb socket and provide a wireless interface for a user device, said user device being connected to said electrical apparatus via a power line capable of carrying a data signal superimposed upon a power signal, said electrical apparatus comprising:

a bulb;

an antenna within said bulb; and

a contact coupled to said bulb, wherein said contact connects said power line to said antenna;

wherein said antenna receives a user data signal from said user device via said power line, and wherein said antenna transmits said user data signal wirelessly.

12. The electrical apparatus of claim 11 further comprising a transceiver, wherein said user data signal is a baseband signal, and wherein said transceiver modulates said baseband signal prior to transmission by said antenna.

13. The electrical apparatus of claim 11, wherein said electrical apparatus receives a remote data signal wirelessly from a remote device and transmits said remote data signal superimposed upon said power signal to said user device via said power line.

14. The electrical apparatus of claim 13 further comprising a transceiver, wherein said remote data signal is a baseband signal, and wherein said transceiver demodulates said baseband signal after wireless reception of said remote data signal by said antenna.

15. The electrical apparatus of claim 11, wherein said user data signal is a modulated signal.

16. An light bulb adapted to connect to a power line connector and provide a wireless interface for a user device, said user device being connected to said light bulb via a power line capable of carrying a data signal superimposed upon a power signal, said light bulb comprising:

an antenna; and

a contact coupled to said antenna, wherein said contact connects said power line to said antenna;

wherein said light bulb receives a remote data signal from a remote device wirelessly via said antenna and transmits said remote data signal superimposed upon said power signal to said user device via said power line.

17. The light bulb of claim 16 further comprising a transceiver, wherein said remote data signal is a baseband signal, and wherein said transceiver demodulates said baseband signal after reception by said antenna.

18. The light bulb of claim 16, wherein said antenna receives a user data signal from said user device via said power line and transmits said user data signal wirelessly.

19. The light bulb of claim 18 further comprising a transceiver, wherein said user data signal is a baseband signal, and wherein said transceiver modulates said baseband signal prior to transmission of said baseband signal wirelessly.

20. The light bulb of claim 18, wherein said user data signal is a modulated signal.

21. The light bulb of claim 16, wherein said power signal powers on said light bulb and said user device.
