Abstract

A method and apparatus for transmitting wireless signals. An apparatus comprises a stringer having a channel and a waveguide located within the channel. The waveguide is capable of carrying a number of wireless signals.

Claims

1. An apparatus comprising:

a stringer having a channel; and

a waveguide located within the channel, wherein the waveguide is capable of carrying a number of wireless signals.

2. The apparatus of claim 1, wherein the number of wireless signals is selected from at least one of an information signal and a power signal.

3. The apparatus of claim 1 further comprising:

a plurality of devices associated with the stringer, wherein the plurality of devices is capable of exchanging the number of wireless signals carried in the waveguide.

4. The apparatus of claim 3, wherein the plurality of devices is selected from at least one of a computer, a line replaceable unit, a sensor, and an actuator.

5. The apparatus of claim 1, wherein the stringer is capable of being attached to one of a skin on a fuselage of an aircraft, a skin on a wing of the aircraft, a frame of the aircraft, and a rib of the aircraft.

6. The apparatus of claim 3, wherein the plurality of devices and the stringer are part of a network data processing system.

7. The apparatus of claim 6, wherein the network data processing system is located in a vehicle.

8. The apparatus of claim 6, wherein the network data processing system is selected from at least one of a health monitoring system, a flight control system, an in-flight entertainment system, and an environmental control system.

9. The apparatus of claim 7, wherein the vehicle is selected from one of an aircraft, a spacecraft, a submarine, and a surface ship.

10. The apparatus of claim 1 further comprising:

a number of stringers, wherein each of the number of stringers has an associated waveguide.

11. The apparatus of claim 1 further comprising:

an access point to the waveguide.

12. The apparatus of claim 11, wherein the access point comprises one of a transmission line, a probe, and an antenna.

13. The apparatus of claim 1, wherein the stringer comprises:

a composite part having a first channel; and

foam located within the first channel, wherein the foam has a second channel, wherein the waveguide is located within the second channel.

14. The apparatus of claim 13, wherein the waveguide comprises a metal material attached to a wall of the second channel.

15. The apparatus of claim 1 further comprising:

an aircraft, wherein the stringer is attached to an interior of the aircraft.

16. The apparatus of claim 1, wherein the stringer comprises:

a composite stringer having the channel; and

a conductive material in the channel, wherein the conductive material forms the waveguide.

17. An aircraft network data processing system comprising:

a plurality of composite stringers attached to a skin of an aircraft and capable of carrying a number of wireless signals selected from at least one of an information signal and a power signal, wherein each stringer in the plurality of composite stringers comprises a composite material having a first channel, foam located in the first channel and having a second channel, and a waveguide located in the second channel; and

a plurality of devices associated with the plurality of composite stringers and capable of exchanging the number of wireless signals carried in the plurality of composite stringers.

18. The aircraft network data processing system of claim 17, wherein the aircraft network data processing system comprises at least one of a health monitoring system, a flight control system, an in-flight entertainment system, and an environmental control system.

19. A method for transmitting wireless signals in a vehicle, the method comprising:

transmitting a number of wireless signals from a first device into a number of waveguides located in a number of stringers in the vehicle;

carrying the number of wireless signals in the number of waveguides in the number of stringers; and

receiving the number of wireless signals from the number of waveguides at a second device.

20. The method of claim 19, wherein the number of wireless signals is selected from at least one of an information signal and a power signal.

21. The method of claim 19, wherein the first device and the second device are selected from at least one of a computer, a sensor, an actuator, and a line replaceable unit.

22. The method of claim 19, wherein a transmission line connects a first stringer in the number of stringers with a second stringer in the number of stringers.

23. The method of claim 19, wherein a number of devices in addition to the first device and the second device are present in the vehicle.

24. The method of claim 19, wherein the number of waveguides in the number of stringers are part of a network in the vehicle, and wherein the network further comprises at least one of a number of transmission lines, a number of optical cables, and a number of air interfaces.
