Abstract

A channel allocation method for a communication network defines a definite purpose channel group that carries signals for definite purpose system devices, such as non-flight critical applications in an aircraft, and a public channel group that carries signals for user devices, such as wireless PDAs, phones and computers used by passengers. By pre-allocating discrete channel groups for different definite purpose system devices and by separating definite purpose channels (for definite purpose system devices) from public channels (for user devices), the invention allows wireless definite purpose system devices and wireless user devices to co-exist in the same operating environment without creating signal interference that could degrade the performance of the devices.

Claims

1. A wireless communication method for a network, comprising:

selecting at least one frequency band for transmitting data;

allocating a plurality of definite purpose channels in a first portion of the at least one frequency band, wherein the plurality of definite purpose channels corresponds with at least one definite purpose function and wherein each definite purpose channel carries data associated with at least one definite purpose system device to be connected to the network and that carries out one definite purpose function; and

allocating separately a second plurality of definite purpose channels in a second portion of the at least one frequency band.

2. The wireless communication method of claim 1, wherein the plurality of definite purpose channels is divided into a plurality of definite purpose channel groups, wherein each definite purpose channel group corresponds with one definite purpose function.

3. The wireless communication method of claim 1, wherein the allocating steps comprises conducting frequency separation.

4. The wireless communication method of claim 3, wherein the frequency separation is at least one selected from the group consisting of carrier separation, logical channel separation, and frequency multiplexing.

5. The wireless communication method of claim 1, further comprising the step of forming a plurality of logical sub-channels within each definite purpose channel.

6. The wireless communication method of claim 5, wherein the logical sub-channels are formed via code division multiple access (CDMA).

7. The wireless communication method of claim 1, further comprising allocating at least one public channel for carrying data corresponding to at least one user device.

8. The wireless communication method of claim 7, wherein said at least one public channel is defined to comply with at least one wireless communication standard.

9. The wireless communication method of claim 8, wherein said at least one wireless communication standard is at least one selected from the group consisting of 802.11 and Bluetooth.

18. The wireless communication method of claim 1, including controlling a bandwidth associated with at least one of the plurality of definite purpose channels and the at least one public channel.

10. A wireless server for a wireless communication network, comprising:

a core acting as a computer server; and

an interface coupled to the core, wherein the interface allocates a plurality of definite purpose channels, wherein each definite purpose channel carries data associated with at least one definite purpose system device to be connected to the network, wherein the interface provides a communication link between the definite purpose system device and the core and wherein the interface separately allocates at least one public channel to carry data associated with at least one user device according to a wireless communication standard.

11. The wireless server of claim 10, wherein the interface comprises a plurality of radios, each radio corresponding with one definite purpose channel to communicate with a corresponding radio on the definite purpose system device.

12. The wireless server of claim 11, further comprising a public channel radio corresponding with a public channel to communicate according to a wireless communication standard with a corresponding radio on a user device.

19. The wireless server of claim 10, wherein the interface controls a bandwidth associated with at least one of the plurality of definite purpose channels and the at least one public channel.

13. (canceled)

14. A wireless communication network, comprising:

a plurality of definite purpose system devices, each definite purpose system device having an associated device radio;

a wireless server, comprising

a core acting as a computer server, and

an interface coupled to the core, wherein the interface allocates a plurality of definite purpose channels, wherein each definite purpose channel carries data associated with at least one definite purpose system device to be connected to the network, wherein the interface provides a communication link between the definite purpose system device and the base station, wherein the interface separately allocates at least one public channel to carry data associated with at least one user device according to a wireless communication standard; and

an antenna providing a wireless communication link between the plurality of definite purpose system devices and the wireless server.

15. The wireless communication network of claim 14, wherein the interface comprises a plurality of radios, each radio corresponding with one definite purpose channel to communicate with a corresponding radio on the definite purpose system device.

16. The wireless communication network of claim 15, further comprising a public channel radio corresponding with a public channel to communicate according to a wireless communication standard with a corresponding radio on a user device.

20. The wireless communication network of claim 14, wherein the interface further controls a bandwidth associated with at least one of the definite purpose channels and the at least one public channel.

17. (canceled)
