Abstract

A wireless local area network adapted for use by users traveling on a mobile platform such as an aircraft. The network includes a network server located on the mobile platform, and at least one network access point connected to the server and accessible wirelessly by at least one user portable electronic device over one of a plurality of non-overlapping network frequency channels. The RF characteristics of this wireless network are specifically tailored to meet applicable standards for electromagnetic compatibility with aircraft systems and RF exposure levels for passengers and flight crews.

Claims

1. A wireless local area network adapted for use by users traveling on a mobile platform, wherein the mobile platform has a plurality of rows of seats, the network comprising:

a network server located on the mobile platform;

a plurality of network access components each independently associated with a specified seating area on the mobile platform, each being in communication with the network server, and each network access component being accessible wirelessly by a predetermined number of portable electronic devices;

each of said network access components including an antenna;

at least first and second ones of the network access components further being located at spaced apart ones of said seat rows in the mobile platform; and

each of the network access components further being configured to wirelessly communicate via its associated said antenna with said portable electronic devices within an associated one of said seating areas on the mobile platform while enabling roaming of a given one of said portable electronic devices between said first and second ones of the network access components; and

a communication system for wirelessly linking said network server on said mobile platform with a subsystem disposed remotely from said mobile platform.

2. The wireless local area network of claim 1, wherein the network access components are each operably associated with at least one spaced apart seat row.

3. The wireless local area network of claim 1, wherein adjacently positioned ones of said network access points operate on non-overlapping frequency channels.

4. The wireless local area network of claim 1, wherein each of the network access components is configured to transmit and receive signals using a spread-spectrum modulation method.

5. The wireless local area network of claim 1, wherein each of the network access components is configured to provide a wireless communications link to only ones of said portable electronic devices that meet a predetermined standard for electromagnetic interference.

6. The wireless local area network of claim 1, wherein each of the network access components is configured to provide a wireless communications link to only ones of said portable electronic devices that meet a predetermined standard for at least one of health and safety.

7. A wireless local area network adapted for use by users traveling on a mobile platform, wherein the mobile platform has a plurality of rows of seats, the network comprising:

a network server located on the mobile platform;

a plurality of network access components each forming a network access point, and each being independently associated with a different, predetermined seating row on the mobile platform, and each being in communication with the network server;

each said network access component being accessible wirelessly by at least one portable electronic device located in its associated said seating row;

each of said network access components including an antenna;

each of the network access components further being configured to wirelessly communicate via its associated said antenna with said portable electronic devices within an associated one of said seating rows on the mobile platform while enabling roaming of a given one of said electronic devices between said different ones of said network access components; and

a communication system for wirelessly communicating information between said network server on said mobile platform and a subsystem disposed remotely from said mobile platform, said communication system including a receive antenna and a transmit antenna.

8. The wireless local area network of claim 7, wherein each said network access component provides wireless coverage for ones of said personal electronic devices that are located in a plurality of rows of said seats.

9. The wireless local area network of claim 7, wherein each said network access component is located overhead in a cabin area of the mobile platform.

10. The wireless local area network of claim 7, wherein each said network access component provides a wireless coverage region for covering all of the seats in a given row of said seats within the mobile platform.

11. The wireless local area network of claim 7, wherein adjacently positioned ones of said network access points operate on non-overlapping frequency channels.

12. The wireless local area network of claim 7, wherein each of the network access components is configured to transmit and receive signals using a spread-spectrum modulation method.

13. The wireless local area network of claim 7, wherein each of the network access components is provides a wireless communications link to only ones of said portable electronic devices that meet a predetermined standard for electromagnetic interference.

14. A wireless local area network adapted for use by users traveling on a mobile platform, wherein the mobile platform has a plurality of rows of seats, the network comprising:

a network server located on the mobile platform;

a plurality of network access components each forming a network access point, and each being independently associated with a different, predetermined group of seating rows on the mobile platform, and each being in communication with the network server;

each said network access component being accessible wirelessly by at least one portable electronic device located within its associated said group of seating rows;

each of said network access components including an antenna located in an overhead area of a cabin of said mobile in which said rows of seats are located;

each of the network access components further enabling roaming of a given one of said electronic devices between said different ones of said network access components; and

a communication system for wirelessly communicating information between said network server on said mobile platform and a subsystem disposed remotely from said mobile platform, said communication system including a receive antenna and a transmit antenna.

15. The wireless network of claim 14, wherein each of the network access components transmits and receives signals using a spread-spectrum modulation method.

16. The wireless network of claim 14, wherein each of the network access components is located in an overhead area within a cabin area in which said seat rows are located.

17. The wireless network of claim 14, wherein adjacent ones of each of the network access components operate on non-overlapping frequency channels.

18. The wireless network of claim 14, wherein each said network access point is configured to operate with a predetermined maximum number of said personal electronic devices at any given time.
