Abstract

An aircraft in-flight entertainment (IFE) system includes an antenna, an external communications transceiver connected to the antenna for communicating external the aircraft, and a plurality of seat electronic boxes (SEBs) spaced throughout the aircraft for distributing entertainment related data. A distribution network is connected to the SEBs and to the external communications transceiver. An internal communications transceiver is connected to the distribution network for establishing an external communications link with a portable wireless device carried by a passenger internal to the aircraft.

Claims

an internal communications transceiver connected to said distribution network for establishing an external communications link with a portable wireless device carried by a passenger internal to the aircraft;

the portable wireless device being selectively operable in a low power mode during communications with said internal communications transceiver, and a transmit power of the portable wireless device operating in the low power mode being less than one-half a transmit power of the portable wireless device operating in a normal power mode.

2. An aircraft IFE system according to claims 1 wherein said internal communications transceiver comprises an infrared transceiver for communicating with the portable wireless device.

3. An aircraft IFE system according to claim 1 wherein said internal communications transceiver commands the portable wireless device from a normal power mode to a low power mode.

4. An aircraft IFE system according to claim 1 wherein said distribution network comprises an Ethernet network.

5. An aircraft IFE system according to claim 1 wherein the portable wireless device comprises at least one of a cellular telephone and a pager.

6. An aircraft IFE system according to claim 1 wherein said internal communications transceiver comprises a signal strength measurement circuit for measuring a level of a transmitted signal from the portable wireless device.

7. An aircraft IFE system according to claim 1 wherein said internal communications transceiver communicates with more than one portable wireless device.

8. An aircraft IFE system according to claim 1 wherein said internal communications transceiver operates based upon a unique address assigned to each portable wireless device.

9. An aircraft IFE system according to claim 1 further comprising:

an entertainment source connected to said plurality of SEBs;

at least one video display unit (VDU) connected to each SEB; and

a respective passenger control unit (PCU) associated with each of said VDUs.

10. An aircraft IFE system according to claim 9 wherein said entertainment source comprises at least one of a direct broadcast satellite (DBS) receiver, a terrestrial television (TV) receiver, and a satellite radio receiver for receiving radio signals.

11. An aircraft in-flight entertainment (IFE) system comprising:

an antenna;

an external communications transceiver connected to said antenna for communicating external to the aircraft; and

a plurality of seat electronic boxes (SEBs) spaced throughout the aircraft for distributing entertainment related data, at least one SEB comprising an internal communications transceiver for establishing a communications link between said external communications transceiver and a portable wireless device carried by a passenger internal to the aircraft, the portable wireless device being selectively operable in a low power mode during communications with said internal communications transceiver, and a transmit power of the portable wireless device operating in the low power mode being less than one-half a transmit power of the portable wireless device operating in a normal power mode.

12. An aircraft IFE system according to claim 11 wherein said internal communications transceiver commands the portable wireless device from a normal power mode to the low power mode.

13. An aircraft IFE system according to claim 11 further comprising cabling connecting said external communications transceiver to said at least one SEB comprising said internal communications transceiver, and wherein the communications link is established over said cabling.

14. An aircraft IFE system according to claim 11 wherein said external communications transceiver and said internal communications transceiver communicate with one another via an Ethernet network.

15. An aircraft IFE system according to claim 11 wherein the portable wireless device comprises at least one of a cellular telephone and a pager.

16. An aircraft IFE system according to claim 11 wherein said internal communications transceiver comprises a signal strength measurement circuit for measuring a level of a transmitted signal from the portable wireless device.

17. An aircraft IFE system according to claim 11 wherein said internal communications transceiver communicates with more than one portable wireless devices.

18. An aircraft IFE system according to claim 11 wherein said internal communications transceiver operates based upon a unique address assigned to each portable wireless device.

19. An aircraft IFE system according to claim 11 further comprising:

an entertainment source connected to said plurality of SEBs;

at least one video display unit (VDU) connected to each SEB; and

a respective passenger control unit (PCU) associated with each of said VDUs.

20. An aircraft IFE system according to claim 19 wherein said entertainment source comprises at least one of a direct broadcast satellite (DBS) receiver, a terrestrial television (TV) receiver, and a satellite radio receiver for receiving radio signals.

21. A method for operating a portable wireless device carried by a passenger within an aircraft in-flight entertainment (IFE) system comprising an antenna, an external communications transceiver connected to the antenna for communicating external to the aircraft, a plurality of seat electronic boxes (SEBs) spaced throughout the aircraft for distributing entertainment related data, a distribution network connected to the SEBs and to the external communications transceiver, and an internal communications transceiver connected to the distribution network, the method comprising:

establishing over the distribution network a communications link between the external communications transceiver and the portable wireless device via the internal communications transceiver, the portable wireless device being selectively operable in a low power mode during communications with the internal communications transceiver, and a transmit power of the portable wireless device operating in the low power mode being less than one-half a transmit power of the portable wireless device operating in a normal power mode.

22. A method according to claims 21 wherein the internal communications transceiver comprises an infrared transceiver for communicating with the portable wireless device.

23. A method according to claim 21 wherein the internal communications transceiver commands the portable wireless device from a normal power mode to a low power mode.
