Abstract

A wireless transmission system operating in a 60 GHz frequency range comprises fixed hubs (public download server) (2) and mobile terminals (1). The fixed hubs (2) have antennas (4) with a wide angle beam shape. The mobile terminals (1) have antennas (3) with a narrow angle beam shape. The fixed hubs (public download server) (2) are connected by means of a connection line (5) to an information source such as a network backbone or a main server.

Claims

1. A wireless transmission system, comprising:

a plurality of public access servers and at least one mobile terminal,

wherein the mobile terminal is designed to upload/download content from one of said public access servers by means of a wireless transmission and the public download servers all operate with the same transmission frequency in a non-licensed band;

wherein each public access server downloads/uploads content to mobile terminals only within a small localized area; and

wherein there is no hand-over between adjacent public access servers.

2. The wireless transmission system according to claim 1, wherein the communication between the mobile terminal and respectively a public access server is free of charge.

3. The wireless transmission system according to claim 1, wherein the uploading/downloading of content is charged to the user of the mobile terminal.

4. The wireless transmission system according to claim 1, wherein said

small localized area is within 20 meters of each public download server.

5. A method for uploading and/or downloading content from public access servers to/from mobile terminals over an air interface,

wherein the air interface uses a non-licensed frequency band and the transmission itself is free of charge,

wherein each public access server downloads/uploads content to/from a mobile terminal within a small localized area in the vicinity of that public access server, and

wherein there is no hand-over between adjacent public access servers.

6. The method according to claim 5, wherein the user of a mobile terminal is charged for uploading/downloading content.

7. The method according to claim 5, wherein a service provider is owner of at least one public access server.

8. The method according to claim 5, wherein the non-licensed frequency band is a 60 GHz band.

9. The method according to claim 5, wherein the public access server is installed in a large hall environment.

10. The method according to claim 5, wherein the public access server is installed in public vehicles.

11. Method according to claim 5, wherein the public access server is installed facing sidewalls.

12. The method according to claim 5, wherein the public access server is installed at gas stations or traffic lights.

13. A wireless transmission system comprising:

a fixed hub connected to an information source, said fixed hub provided with a wide angle beam antenna;

a hand-held mobile terminal provided with a narrow beam antenna;

wherein content from said information source is downloaded to said mobile terminal via said fixed hub only within a small localized area of said fixed hub; and

wherein said fixed hub is one of a plurality of fixed hubs; and

there is no handover between said fixed hubs.

14. The wireless transmission system according to claim 13, wherein the fixed hub is provided with an antenna with a kidney shaped beam in cross-section.

15. The wireless transmission system according to claim 14 wherein said antenna is mounted on a ceiling, and said kidney shaped beam has a local minimum level in said cross section in a direction opposing said ceiling.

16. The wireless transmission system according to claim 13 wherein said small localized area is within 20 meters of said fixed hub.

17. The wireless transmission system according to claim 13, wherein said fixed hub is further adapted to upload information from said mobile terminal.

18. The wireless transmission system according to claim 13, wherein said system is designed for the transmission of data in the 60 GHz range.

19. The wireless transmission system according to claim 13, wherein said information source is a broadband data highway, and said content includes video content.

20. The wireless transmission system according to claim 13, wherein said content includes contents of news information centers.
