Abstract

A local area network comprises a plurality of access points. Each access point includes a first transceiver for wireless communication with one or more user workstations. The access points include second transceivers for wireless communication with one another. At least one of the access points is configured for movement to enable re-configuration of the local area network.

Claims

1. A local area network comprising a plurality of access points, each access point being provided with a first transceiver for wireless communication with one or more user workstations, wherein the access points include second transceivers for wireless communication with one another, and wherein the access points are configured for movement to enable reconfiguration of the local area network.

2. A local area network as claimed in claim 1, wherein each access point configured for movement includes a drive for moving that access point to enable reconfiguration of the local area network.

3. A local area network as claimed in claim 2, wherein each access point configured for movement includes a buoyancy device, the buoyancy devices being such that, in use, the access points can be positioned so as to float at predetermined heights.

4. A local area network as claimed in claim 3, wherein each of the buoyancy devices includes a helium balloon.

5. A local area network as claimed in claim 4, wherein each of the helium balloons is such that its buoyancy substantially matches the combined mass of the associated access point and drive.

6. A local area network as claimed in claim 2, wherein a respective electric motor and propeller comprise the drive of each access point configured for movement.

7. A local area network as claimed in claim 1, further comprising a track arrangement along which the access points configured for movement can be moved.

8. A local area network as claimed in claim 7, wherein each access point configured for movement includes a support wheel engageable with the track arrangement.

9. A local area network as claimed in claim 1, wherein each first transceiver is arranged to communicate with the or each associated user workstation using Internet protocol.

10. A local area network as claimed in claim 1, wherein the second transceivers are arranged to communicate with each other using the IEEE 802.11b, the IEEE802.11a, or the HiperLAN/2 protocol.

11. A local area network as claimed in claim 1, wherein each of the access points is configured for movement.

12. A local area network comprising a plurality of access points, each access point including a first transceiver for wireless communication with one or more user workstations, and the access points include second transceivers for wireless communication with one another, wherein the access points are configured for movement to enable reconfiguration of the local area network, and wherein each access point includes a buoyancy device, the buoyancy devices being such that, in use, the access points can be positioned to float at predetermined heights.

13. A local area network comprising a plurality of access points, each access point including a first transceiver for wireless communication with one or more user workstations, and the access points including second transceivers for wireless communication with one another, wherein the access points are configured for movement to enable reconfiguration of the local area network, and wherein the local area network further comprises a track arrangement along which the access points can be moved.

14. A local area network comprising a plurality of access points, each access point including a first transceiver for wireless communication with one or more user workstations, and the access points including second transceivers for wireless communication with one another, wherein the access points are configured for movement to enable reconfiguration of the local area network, wherein each access point includes a buoyancy device, the buoyancy devices being such that, in use, the access points can be positioned so as to float at predetermined heights, and wherein each access point includes a drive for moving that access point to enable reconfiguration of the local area network, each of the buoyancy devices including a helium balloon, each of the helium balloons being such that its buoyancy substantially matches the combined mass of the associated access point and drive, and the drive of each access point including an electric motor and propeller.

15. A local area network comprising a plurality of access points, each access point including a first transceiver for wireless communication with one or more user workstations, and the access points including second transceivers for wireless communication with one another, wherein the access points are configured for movement to enable reconfiguration of the local area network, wherein each access point includes a drive for moving that access point to enable reconfiguration of the local area network, and wherein the local area network further comprises a track arrangement along which the access points can be moved, each access point including a support wheel engageable with the track arrangement.

16. An access point for a local area network comprising a first transceiver for wireless communication with one or more user workstations, a second transceiver for wireless communication with other access points, wherein the access points is configured for movement to enable reconfiguration of the local area network.

17. An access point as claimed in claim 16, wherein the access point includes a drive for moving that access point to enable reconfiguration of the local area network.

18. An access point as claimed in claim 17, wherein the access point includes a buoyancy device such that, in use, the access point can be positioned so as to float at predetermined heights.

19. An access point as claimed in claim 18, wherein the buoyancy device includes a helium balloon.

20. An access point as claimed in claim 19, wherein the helium balloon is such that its buoyancy substantially matches the combined mass of the associated access point and drive.

21. An access point as claimed in claim 17, the drive of each access point configured for movement includes an electric motor and propeller.

22. An access point as claimed in claim 16, wherein the access point includes a support wheel adapted to be engageable with a track arrangement along which the access points configured for movement can be moved.
