Abstract

A communications system for an aircraft carrying at least some 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 wireless local area network (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. An aircraft data memory cache is in the aircraft and cooperates with the access point for storing common data accessible by the PEDs during flight of the aircraft.

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

an aircraft data memory cache in the aircraft and cooperating with said at least one access point for storing common data accessible by the PEDs during flight of the aircraft.

2. The communications system according to claim 1 wherein said aircraft data memory cache is for storing common data in a form of web pages.

3. The communications system according to claim 1 wherein said aircraft data memory cache is for storing common data related to at least one of services and products.

4. The communications system according to claim 3 further comprising a purchase acceptance controller in the aircraft and cooperating with the WLAN to accept a purchase from at least one PED responsive to the common data related to at least one of services and products.

5. The communications system according to claim 3 wherein said aircraft data memory cache pushes the common data related to at least one of services and products to the PEDs.

6. The communications system according to claim 3 wherein said aircraft data memory cache permits the PEDs to pull the common data related to at least one of services and products therefrom.

7. The communications system according to claim 1 wherein said aircraft data memory cache is for storing common data related to interactive maps, with the PEDs being used for scrolling in and out of a displayed map.

8. The communications system according to claim 7 wherein the communications system further comprises a positioning determining device for determining a position of the aircraft so that a displayed interactive map corresponds to the position of the aircraft.

9. The communications system according to claim 1 wherein said aircraft data memory cache is updatable when the aircraft is on the ground.

10. The communications system according to claim 1 wherein said aircraft data memory cache is updatable when the aircraft is airborne.

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

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

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

14. 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 memory cache in the aircraft and cooperating with said at least one access point for storing common data accessible by the PEDs during flight of the aircraft.

15. The aircraft communications system according to claim 14 wherein said aircraft data memory cache is for storing common data in a form of web pages.

16. The aircraft communications system according to claim 14 wherein said aircraft data memory cache is for storing common data related to at least one of services and products.

17. The aircraft communications system according to claim 16 further comprising a purchase acceptance controller in the aircraft and cooperating with the WLAN to accept a purchase from at least one PED responsive to the common data related to at least one of services and products.

18. The aircraft communications system according to claim 16 wherein said aircraft data memory cache pushes the common data related to at least one of services and products to the PEDs.

19. The aircraft communications system according to claim 16 wherein said aircraft data memory cache permits the PEDs to pull the common data related to at least one of services and products therefrom.

20. The aircraft communications system according to claim 14 wherein said aircraft data memory cache is updatable when the aircraft is on the ground.

21. The aircraft communications system according to claim 14 wherein said aircraft data memory cache is updatable when the aircraft is airborne.

22. The aircraft communications system according to claim 14 wherein the data communications comprise at least one of email data and text message data.

23. The aircraft communications system according to claim 14 wherein the WLAN comprises at least one of an 802.11 WLAN and an 802.16 WLAN.

24. 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:

storing common data accessible by the PEDs during flight of the aircraft using an aircraft data memory cache in the aircraft and cooperating with the at least one access point.

25. The method according to claim 24 wherein storing comprises storing common data in a form of web pages.

26. The method according to claim 24 storing comprises storing common data related to at least one of services and products.

27. The method according to claim 26 further comprising accepting a purchase from at least one PED responsive to the common data related to at least one of services and products a purchase using an acceptance controller in the aircraft and cooperating with the WLAN.

28. The method according to claim 24 further comprising pushing the common data related to at least one of services and products to the PEDs from the aircraft data memory cache.

29. The method according to claim 24 further comprising permitting the PEDs to pull the common data related to at least one of services and products from the aircraft data memory cache therefrom.

30. The method according to claim 24 further comprising updating the aircraft data memory cache when the aircraft is on the ground.
