Abstract

A beacon is placed at a specific location, such as a bus stop and has a local communicator which transmits a code to a mobile telephone. The code identifies a predetermined item of information stored on a remote server, such as a bus timetable document. This information is retrieved by the mobile telephone using its network communicator. The mobile telephone then transmits a copy of the information to the beacon which stores it in its cache and also displays the document to its user. A PDA, which lacks a network communicator, is then able to retrieve the cached information directly from the beacon using only its local communicator. The PDA then displays the bus timetable document to its user.

Claims

1. A local information delivery system comprising a beacon, wherein:

i) the beacon has a memory adapted to store a code identifying a predetermined item of information;

ii) the beacon has a local communications means adapted to transmit the code wirelessly to at least one client device when the at least one client device is in a vicinity of the beacon, the client device then using this code to upload the predetermined item of information by way of a global communications system;

iii) the local communications means of the beacon is adapted to receive the uploaded item of information when transmitted from the at least one client device;

iv) the beacon stores in its memory the item of information received or uploaded from the at least one client device; and

v) the local communications means of the beacon is adapted to transmit the item of information, in place of or alongside the code, to at least one further client device when in the vicinity of the beacon.

2. A system as claimed in claim 1, wherein the client device is a mobile phone, a Personal Digital Assistant, a camera, another beacon, a smart card, a printer, an electronic lock, or a standalone or personal electronic device.

3. A system as claimed in claim 1, wherein the beacon includes a plurality of local communications means.

4. A system as claimed in claim 3, wherein the beacon transmits using a first local communications means and receives using a second, different, local communications means.

5. A system as claimed in claim 1, wherein the beacon stores multiple versions of the item of information in different formats.

6. A system as claimed in claim 1, wherein the beacon stores multiple versions of the code in different formats.

7. A system as claimed in claim 5, wherein the beacon senses predetermined characteristics of the client device by way of the local communications means and transmits a version of the item of information or code appropriate to the sensed characteristics of the client device.

8. A system as claimed in claim 1, wherein the beacon monitors its memory to determine if the item of information is out-of-date.

9. A system as claimed in claim 8, wherein the beacon is adapted to transmit the code as well as, or instead of, the item of information if the stored item of information is out of date.

10. A system as claimed in claim 1, wherein the beacon is operable to transmit additional information, together with the code, the additional information being information for further transmittal by the client device to a remote system.

11. A system as claimed in claim 1, wherein the beacon is operable to receive an item of information that originates from or is modified by a first client device, and to transmit the item of information to a second client device, thus providing peer-to-peer communications capability.

12. A system as claimed in claim 1, wherein the client device is another beacon.

13. A system as claimed in claim 1, wherein the beacon is provided with means for sensing when a client device is within a predetermined range of

transmission, and wherein the beacon is operable only to transmit the code when a client device is within range.

14. A method of efficiently updating information stored in a beacon having a memory and at least one local communications means, in which:

i) a client device retrieves or uploads a code from the beacon by way of the local communications means, the code identifying a predetermined item of information that is available over a network;

ii) the client device uses a network communications system to retrieve or upload the predetermined item of information from the network and then transmits a copy of the item of information to the beacon using the local communications means;

iii) the beacon stores the predetermined item of information in its memory;

iv) other client devices then retrieve or upload the predetermined item of information directly from the beacon by way of the local communications means.

15. A method according to claim 14, wherein the client device is a mobile phone, a Personal Digital Assistant, a camera, another beacon, a smart card, a printer, an electronic lock, or a standalone or personal electronic device.

16. A method according to claim 14, wherein the beacon includes a plurality of local communications means.

17. A method according to claim 16, wherein the beacon transmits using a first local communications means and receives using a second, different, local communications means.

18. A method according to claim 14, wherein the beacon stores multiple versions of the item of information in different formats.

19. A method according to claim 14, wherein the beacon stores multiple versions of the code in different formats.

20. A method according to claim 18, wherein the beacon senses predetermined characteristics of the client device by way of the local communications means and transmits a version of the item of information or code appropriate to the sensed characteristics of the client device.

21. A method according to claim 14, wherein the beacon monitors its memory to determine if the item of information is out-of-date.

22. A method according to claim 21, wherein the beacon transmits the code as well as, or instead of, the item of information if the stored item of information is out of date.

23. A method according to claim 14, wherein the code is transmitted to the other client devices together with the item of information.

24. A method according to claim 14, wherein the beacon transmits additional information, together with the code, the additional information being transmitted further by at least one client device to a remote system.

25. A method according to claim 14, wherein the beacon receives an item of information that originates from or is modified by a first client device, and transmits the item of information to a second client device, thus providing peer-to-peer communications capability.

26. A method according to claim 14, wherein the client device is another beacon.
