Abstract

An aircraft wireless network in an aircraft includes a maintenance server, a cabin server, a radio switch, a network switch, and a cabin access point. The network switch and radio switch are configured to arrange the aircraft wireless network according to at least two distinct configurations. In a first configuration the cabin server is permitted to connect to the at least one cabin access point by the network switch and a first aircraft access point is connected to the external antenna by the radio switch. In a second configuration the maintenance server is permitted to connect to the at least one cabin access point by the network switch and a second aircraft access point is connected to the external antenna by the radio switch. In the first and second configurations the maintenance and cabin servers are prohibited from simultaneously connecting to the at least one cabin access point.

Claims

1. An aircraft wireless network in an aircraft, the aircraft wireless network comprising:

a maintenance server;

a cabin server;

a radio switch connected to an external antenna, a first aircraft access point, and a second aircraft access point;

a network switch; and

at least one cabin access point connected to at least one internal antenna,

wherein the network switch and the radio switch are configured to arrange the aircraft wireless network according to at least two distinct configurations, in a first configuration the cabin server is permitted to connect to the at least one cabin access point by the network switch and the first aircraft access point is connected to the external antenna by the radio switch, in a second configuration the maintenance server is permitted to connect to the at least one cabin access point by the network switch and the second aircraft access point is connected to the external antenna by the radio switch, and

in the first and second configurations the said maintenance and cabin servers are prohibited from simultaneously connecting to the said at least one cabin access point.

2. The aircraft wireless network according to claim 1, wherein:

the cabin server is connected to the first aircraft access point; and

the maintenance server is connected to the second aircraft access point, wherein in the first configuration the cabin server is permitted to establish a wireless connection using the external antenna, in the second configuration the maintenance server is permitted to establish a wireless connection using the external antenna, and in the first and second configurations the first aircraft access point and the second aircraft access point are prohibited from simultaneously connecting to the external antenna.

3. The aircraft wireless network according to claim 2, wherein the first aircraft access point is connected to at least one second antenna independently of the radio switch.

4. The aircraft wireless network according to claim 2, further comprising a command generator that sets the configuration of the aircraft wireless network according to the first configuration or according to the second configuration.

5. The aircraft wireless network according to claim 2, wherein the at least one aircraft access point includes an access point according to the 802.11a b, or g standard.

6. The aircraft wireless network according to claim 1, wherein the at least one cabin access point includes an access point according to the 802.11a, b, or g standard.

7. An aircraft comprising the aircraft wireless network according to any one of claims 1-4 and 6.

8. A method for an aircraft wireless network in an aircraft, the aircraft wireless network comprising a maintenance server, a cabin server, a radio switch connected to an external antenna, a network switch, and at least one cabin access point connected to at least one internal antenna, the method comprising:

arranging the wireless network according to a first configuration in which the cabin server is permitted to connect to the at least one cabin access point by the network switch and a first aircraft access point is connected to the external antenna by the radio switch;

arranging the wireless network according to a second configuration in which the maintenance server is permitted to connect to the at least one cabin access point by the network switch and a second aircraft access point is connected to the external antenna by the radio switch; and

prohibiting the maintenance and cabin servers from simultaneously connecting to the at least one cabin access point in the first and second configurations.

9. The method of claim 8, further comprising:

determining a current configuration of the aircraft wireless network prior to setting the configuration of the aircraft wireless network according to the first or second configuration.

10. The method of claim 8, further comprising:

connecting the cabin server to the first aircraft access point;

connecting the maintenance server to the second aircraft access point;

permitting the cabin server to establish a wireless connection using the external antenna in the first configuration;

permitting the maintenance server to establish a wireless connection using the external antenna in the second configuration; and

prohibiting the first aircraft access point and the second aircraft access point from simultaneously connecting to the external antenna in the first and second configurations.

11. The method of claim 8, further comprising:

alerting at least one crew member of the aircraft when a predetermined condition is satisfied while the configuration of the aircraft wireless network corresponds to the said second configuration.

12. The method of claim 11, wherein the predetermined condition comprises a duration of remaining in the second configuration.

13. The method of claim 8, further comprising:

connecting the first aircraft access point to at least one second antenna independently of the radio switch.

14. The method of claim 8, further comprising:

generating a command that sets the configuration of the aircraft wireless network according to the first configuration or the second configuration.

15. The method of claim 8, further comprising:

operating at least one of the cabin access point, the first aircraft access point, and the second aircraft access point as an access point according to the 802.11a, b, or g standard.
