Abstract

A system and method for aircraft communications is provided. The system includes a first wireless base station deployed in a first aircraft and configured to establish one or more wireless links, and a second wireless base station deployed in a second aircraft and configured to establish one or more wireless links. At least one ground-based wireless base station is configured to operatively communicate with the first wireless base station or the second wireless base station while the first aircraft and the second aircraft are in flight. During flight, the first and second wireless base stations establish one or more wireless links with each other to create a wireless network for air-to-air communication. When one of the first or second aircraft is out of range with the ground-based wireless base station and the other aircraft is in range with the ground-based wireless base station, the aircraft that is out of range can send a message to the ground-based wireless base station through the aircraft that is in range.

Claims

1. An aircraft communication system, comprising:

a first wireless base station deployed in a first aircraft and configured to establish one or more wireless links;

a second wireless base station deployed in a second aircraft and configured to establish one or more wireless links;

at least one ground-based wireless base station configured to operatively communicate with the first wireless base station or the second wireless base station while the first aircraft and the second aircraft are in flight;

wherein when the first aircraft and the second aircraft are in flight, the first wireless base station and the second wireless base station establish one or more wireless links with each other to create a wireless network for air-to-air communication, such that when one of the first aircraft or second aircraft is out of range with the ground-based wireless base station and the other aircraft is in range with the ground-based wireless base station the aircraft that is out of range can send a message to the ground-based wireless base station through the aircraft that is in range.

2. The system of claim 1, wherein the first wireless base station and the second wireless base station each comprise a Worldwide Interoperability for Microwave Access (WiMax) transceiver, or any internet protocol (IP) based wireless transceiver.

3. The system of claim 1, wherein the first wireless base station and the second wireless base station each comprise a directional antenna and an omnidirectional antenna.

4. The system of claim 1, wherein the ground-based wireless base station is in operative communication with an air traffic control (ATC) center and an aeronautical operational control (AOC) center at one or more airports.

5. The system of claim 1, further comprising one or more additional wireless base stations each deployed in additional separate aircraft, the one or more additional wireless base stations configured to establish one or more wireless links with the first and second wireless base stations to form a subnetwork for air-to-air communication.

6. The system of claim 5, wherein at least one of the first aircraft, the second aircraft, or the additional separate aircraft comprises a hot air balloon.

7. The system of claim 1, further comprising a data routing system that comprises:

a first ground server in operative communication with a first airport wireless base station;

a second ground server in operative communication with a second airport wireless base station;

a third ground server in operative communication with the ground-based wireless base station;

a data routing center in operative communication with each of the first, second, and third ground servers;

an ATC center in operative communication with the data routing center; and

an AOC center in operative communication with the data routing center.

8. A method for aircraft air-to-air communications, the method comprising:

establishing a plurality of wireless links between a plurality of wireless base stations each deployed in a separate one of a plurality of aircraft to create a wireless network while the plurality of aircraft are in flight; and

routing data transmitted by one or more of the aircraft through the wireless network using one or more data transfer protocols until a desired destination is reached.

9. The method of claim 8, wherein the wireless base stations each comprise a Worldwide Interoperability for Microwave Access (WiMax) transceiver.

10. The method of claim 8, wherein one or more of the plurality of aircraft comprises a hot air balloon.

11. The method of claim 8, wherein at least one of the wireless base stations is in operative communication with a ground-based wireless base station.

12. The method of claim 11, wherein the ground-based wireless base station is in operative communication with an air traffic control center and an aeronautical operational control center at one or more airports.

13. The method of claim 8, wherein the data transfer protocols comprise a data store and forward protocol, a time-based data management protocol, and a data routing preference protocol.

14. The method of claim 13, wherein the time-based data management protocol comprises:

(a) receiving a new message or retrieving a stored message transmitted by one of the aircraft;

(b) determining whether the message is ready to be sent;

(c) if the message is ready to be sent, determining whether a message delivery time is immediate;

(d) if the message delivery time is immediate, delivering the message to a ground station over an available subnetwork and returning to step (a);

(e) if the message delivery time is not immediate, determining whether the message delivery time is infinite;

(f) if the message delivery time is not infinite, determining whether a message delivery timer has timed out;

(g) if the message delivery timer has timed out, delivering the message to the ground station over an available subnetwork and returning to step (a);

(h) if the message delivery timer has not timed out, determining whether a WiMax network is available;

(i) if the WiMax network is available, delivering the message over the WiMax network and returning to step (a);

(j) if the WiMax network is not available, determining whether the message is a retrieved message;

(k) if the message is not a retrieved message, storing the message and returning to step (a);

(l) if the message is a retrieved message, updating a message header of the retrieved message, storing the updated retrieved message, and returning to step (a); and

(m) if the message delivery time is infinite at step (e), determining whether the WiMax network is available and repeating steps (i) to (l).

15. The method of claim 13, wherein the data routing preference protocol comprises selecting between one of:

routing data between airplanes of the same airline;

routing data between airplanes of a given airline and other airplanes of another airline that are associated with the given airline; and

routing data between all airplanes of all airlines.

16. An air-to-air communications network, comprising:
