Abstract

A communications system for an aircraft carrying personnel having personal electronic devices (PEDs) for wireless data communications outside the aircraft includes a ground-based communications network, and an access point in the aircraft for providing a WLAN for data communications with the PEDs. An air-to-ground transceiver in the aircraft cooperates with the access point for data communications with the ground-based communications network. At least one data traffic controller selectively allocates data communications channel capacity between the PEDs and the ground-based communications network.

Claims

1. A communications system for an aircraft carrying at least some personnel having personal electronic devices (PEDs) for wireless data communications outside the aircraft, the communications system comprising:

a ground-based communications network;

at least one access point in the aircraft for providing a wireless local area network (WLAN) for data communications with the PEDs;

an air-to-ground transceiver in the aircraft cooperating with said at least one access point for data communications with said ground-based communications network; and

at least one data traffic controller for selectively allocating data communications channel capacity between the PEDs and the ground-based communications network.

2. The communications system according to claim 1 wherein said at least one data traffic controller comprises a ground-based data traffic controller associated with said ground-based communications network.

3. The communications system according to claim 1 wherein said at least one data traffic controller comprises an aircraft-based data traffic controller associated with said at least one access point and said air-to-ground transceiver.

4. The communications system according to claim 1 wherein said at least one data traffic controller allocates the data communications channel capacity based on a priority of service.

5. The communications system according to claim 4 wherein the data communications comprise flight operational data and non-flight operational data;

and wherein said at least one data traffic controller allocates a higher priority of service to the flight operation data.

6. The communications system according to claim 1 wherein said at least one data traffic controller allocates data communications channel capacity usage among the PEDs.

7. The communications system according to claim 6 wherein said at least one data traffic controller limits data communications exceeding a predetermined portion of the data communications channel capacity for a given PED.

8. The communications system according to claim 1 wherein the data communications comprises at least one of email data and text message data.

9. The communications system according to claim 1 wherein the WLAN comprises at least one of an 802.11 WLAN and an 802.16 WLAN.

10. The communications system according to claim 1 wherein said at least one access point comprises a picocell.

11. An aircraft communications system for an aircraft carrying at least some personnel having personal electronic devices (PEDs) for wireless data communications outside the aircraft with a ground-based communications network, the aircraft communications system comprising:

at least one access point in the aircraft for providing a wireless local area network (WLAN) for data communications with the PEDs;

an air-to-ground transceiver in the aircraft cooperating with said at least one access point for data communications with the ground-based communications network; and

an aircraft data traffic controller in the aircraft for selectively allocating data communications channel capacity between the PEDs and the ground-based communications network.

12. The aircraft communications system according to claim 11 wherein said aircraft data traffic controller allocates the data communications channel capacity based on a priority of service.

13. The aircraft communications system according to claim 12 wherein the data communications comprise flight operational data and non-flight operational data;

and wherein said aircraft data traffic controller allocates a higher priority of service to the flight operation data.

14. The aircraft communications system according to claim 11 wherein said aircraft data traffic controller allocates data communications channel capacity usage among the PEDs.

15. The aircraft communications system according to claim 14 wherein said aircraft data traffic controller limits data communications exceeding a predetermined portion of the data communications channel capacity for a given PED.

16. The aircraft communications system according to claim 11 wherein the data communications comprises at least one of email data and text message data.

17. The aircraft communications system according to claim 11 wherein the WLAN comprises at least one of an 802.11 WLAN and an 802.16 WLAN.

18. A method for operating a communications system for an aircraft carrying at least some personnel having personal electronic devices (PEDs) for wireless data communications outside the aircraft with a ground-based communications network, the communications system comprising at least one access point in the aircraft for providing a wireless local area network (WLAN) for data communications with the PEDs, and an air-to-ground transceiver in the aircraft cooperating with the at least one access point for data communications with the ground-based communications network, the method comprising:

selectively allocating data communications channel capacity between the PEDs and the ground-based communications network using at least one data traffic controller.

19. The method according to claim 18 wherein the at least one data traffic controller comprises a ground-based data traffic controller associated with the ground-based communications network.

20. The method according to claim 18 wherein the at least one data traffic controller comprises an aircraft-based data traffic controller associated with the at least one access point and the air-to-ground transceiver.

21. The method according to claim 18 wherein allocating comprises allocating the data communications channel capacity based on a priority of service.

22. The method according to claim 21 wherein the data communications comprise flight operational data and non-flight operational data;

and wherein the allocating comprises allocating a higher priority of service to the flight operation data.

23. The method according to claim 18 wherein the allocating comprises allocating data communications channel capacity usage among the PEDs.

24. The method according to claim 23 wherein the allocating comprises limiting data communications exceeding a predetermined portion of the data communications channel capacity for a given PED.

25. The method according to claim 18 wherein the data communications comprise at least one of email data and text message data.

26. The method according to claim 18 wherein the WLAN comprises at least one of an 802.11 WLAN and an 802.16 WLAN.
