Abstract

A wireless communication system for a transportation vehicle such as, for example, an aircraft, bus, cruise ship, and train, is presented. The wireless communication system includes an information source containing data content including text, audio and video media, a plurality of wireless interfaces, a plurality of individually identifiable electronic devices coupled to the plurality of wireless interfaces and a wireless local area network (LAN) access point. The wireless LAN access point is coupled to the information source and wirelessly coupled to the plurality of wireless interfaces. In operation, the wireless LAN access point receives data content from the information source, converts the data content into a wireless transmission format and selectively distributes the formatted data content to the plurality of wireless interfaces such that the formatted data content is accessible by at least a selected one of the plurality of individually identifiable electronic devices.

Claims

1. A wireless communication system for a transportation vehicle, comprising:

an information source containing data content;

a plurality of wireless interfaces, each wireless interface fixed in the transportation vehicle and conforming to airborne environmental requirements, configured to wirelessly communicate with the information source;

a plurality of individually identifiable electronic devices, each individually identifiable electronic device configured to communicate with the information source; and

a wireless local area network access point coupled to said information source and wirelessly coupled to said plurality of wireless interfaces, said wireless LAN access point for receiving data content from said information source, converting said data content into a wireless transmission format conforming to airborne environmental requirements and permitting access to the formatted data content only through the plurality of wireless interfaces, wherein each individually identifiable electronic device is wirelessly coupled to a respective wireless interface to communicate with the information source.

2. The wireless communication system as set forth in claim 1, wherein said information source comprises a data server fixedly coupled to said transportation vehicle and logically coupled to an external service provider communication device.

3. The wireless communication system as set forth in claim 1 wherein said plurality of wireless interfaces comprise at least one wireless interface fixedly coupled in said transportation vehicle and at least one wired interface fixedly coupled within one of said plurality of individually identifiable electronic devices.

4. The wireless communication system as set forth in claim 1 wherein said wireless LAN access point selectively distributes said formatted data content by routing said data content to the wireless interfaces supporting selected one of said plurality of individually identifiable electronic devices.

5. The wireless communication system as set forth in claim 1 wherein said communication system supports bidirectional communication between said information source and said plurality of individually identifiable electronic devices such that one of said plurality of individually identifiable electronic devices may request delivery of specific data content from said information source.

6. The wireless communication system as set forth in claim 1 wherein said communication system supports bidirectional communication between said information source and a first subset of said plurality of individually identifiable electronic devices and unidirectional communication between said information source and a second subset of said plurality of individually identifiable electronic devices.

7. The wireless communication system as set for the in claim 1 wherein said plurality of individually identifiable electronic devices include a wireless video display unit.

8. The wireless communication system as set forth in claim 7 wherein said wireless video display unit is comprised of a video display unit for presenting video content to a plurality of passengers.

9. The wireless communication system as set forth in claim 7 wherein said wireless video display unit is comprised of a plurality of video display units for presenting video content to individual ones of a plurality of passengers.

10. The wireless communication system as set forth in claim 9 wherein said plurality of video display units are located within seatback units.

11. The wireless communication system as set forth in claim 1 wherein said plurality of wireless interfaces include an airborne environmental complaint interface fixedly coupled in a passenger control unit, said airborne environmental compliant interface for receiving data from and transmitting data to said wireless LAN access point.

12. The wireless communication system as set forth in claim 1 wherein said plurality of wireless interfaces include a passenger control unit having a plurality of controls and a display, said passenger control unit operable by a passenger for selecting and controlling one of video content, audio content, and combinations thereof.

13. The wireless communication system as set forth in claim 12 wherein said passenger control unit includes a connector for connecting an audio listening device, and wherein a passenger selects audio content accessible at said passenger control unit by said audio listening device.
