Abstract

A mobile device positioning system is disclosed. In one embodiment, the positioning system uses a plurality of independent communication beacons to triangulate mobile device locations. In one embodiment, mobile devices broadcast their location to other mobile devices which use the mobile device broadcasts to triangulate their location.

Claims

1. A system for determining location information of a plurality of mobile devices comprising:

a plurality of stationary antennas configured to broadcast information indicative of the antennas location;

a first mobile device configured receive the information indicative of the antennas location and to determine a location of the first mobile device;

wherein the first mobile device is further configured to broadcast information indicative of the location of the first mobile device directly to a second mobile device;

a second mobile device configured to receive the information indicative of the location of the first mobile device directly from the first mobile device and to determine a location of the second mobile device based in part on the information indicative of the location of the first mobile device.

2. The system of claim 1, further comprising a central processor configured to receive information regarding the location of a plurality of mobile devices.

3. The system of claim 2, wherein the central processor is further configured to determine traffic patterns based on the received information.

4. The system of claim 3, wherein the central processor is further configured to determine an optimal travel route to a desired location for a user.

5. The system of claim 4, wherein the central processor is further configured to send travel route information to the user.

6. The system of claim 1, wherein the first mobile device comprises a mobile telephone.

7. The system of claim 1, wherein the second mobile device comprises a mobile telephone.

8. The system of claim 1, wherein at least one of the first or second mobile devices comprise one or more of a PDA, portable computer;

pager, and mobile telephone.

9. A method of determining the location of a mobile device comprising:

receiving, at a first mobile device, location information indicative of a location of a stationary antenna;

determining a location of the first mobile device; and

broadcasting the location of the first mobile device directly to a second mobile device.

10. The method of claim 9, further comprising receiving at a second mobile device the broadcasted location of the first mobile device directly from the first mobile device.

11. The method of claim 10, further comprising determining a location of the second mobile device based at least in part on the received location of the first mobile device.

12. A mobile device comprising:

a receiver configured to receive wireless signals representative of location information of a plurality of transmitters;

a processor configured to determine a location of the mobile device based on the signals representative of location information of the plurality of transmitters; and

a transmitter configured to transmit the location of the receiver directly to a second mobile device.

13. The mobile device of claim 12, wherein the receiver is reconfigurable to receive signals from different communication protocols.

14. The mobile device of claim 13, wherein the receiver is reconfigurable using software.

15. The mobile device of claim 12, wherein the transmitter is reconfigurable to transmit signals using different communication protocols.

16. The mobile device of claim 14, wherein the transmitter is reconfigurable using software.

17. A system for determining the location of a mobile device comprising:

a plurality of stationary antennas operating independently of a wireless carrier network;

the plurality of antennas configured to broadcast location information indicative of the location of the antennas;

wherein the broadcast locations are configured to be received by a mobile device and used to determine the location of the mobile device.

18. The system of claim 17, wherein the plurality of antennas are further configured to broadcast on an unlicensed spectrum.

19. The system of claim 18, wherein the unlicensed spectrum comprises one or more of 900 MHz, 2.3 GHz, 2.4 GHz, 3.5 GHz, 5.3 GHz and 5.8 GHz.

20. The system of claim 17, further comprising a central station configured to receive information indicative of the location of the mobile device.

21. The system of claim 20, wherein the central station is configured to determine travel route information based on the location of the mobile devices.

22. The system of claim 21, wherein the central station is configured to communicate travel route information to a user.
