Abstract

A system for communicating over a plurality of wireless data networks, the system comprising a software defined radio capable of being configured to operate with a plurality of wireless network services; a radio controller for reconfiguring the radio to operate over a wireless data network; a first database containing information about wireless data networks; wireless location technology used to determine a location of the radio; wherein the wireless location technology determines a location of the radio and the controller compares the location with information contained in the first database to determine available wireless data networks.

Claims

1. A method for a programmable software radio to communicate over a plurality of wireless data networks with a central service facility, the method comprising:

providing the radio with wireless location technology;

providing the radio with data about wireless data networks;

providing the radio with data about pre-selected broadcast media channels;

scanning for pre-selected broadcast media channels to determine a location of the radio;

comparing the location of the radio with data about wireless data networks;

determining available wireless data networks based on the location of the radio;

selecting a wireless data network; and

configuring the radio to communicate over the selected wireless data network.

2. The method of claim 1 wherein the step of providing the radio with data about wireless data networks comprises providing data about coverage area, license agreements, and radio software configuration data.

3. The method of claim 1, wherein the step of providing the radio with wireless location technology comprises providing the radio with handset-based wireless location technology.

4. The method of claim 1 wherein the step of providing the radio with wireless location technology comprises providing the radio with network-based wireless location technology.

5. The method of claim 1 wherein the step of scanning for pre-selected broadcast media channels further comprises scanning for pre-selected broadcast media channels based on broadcast media channels data provided to the radio to determine a location.

6. The method of claim 1 wherein the step of providing the radio with data about media broadcast channels comprises providing data about frequencies, coverage areas and license information.

7. The method of claim 1, wherein the step of determining a location of the radio with wireless location technology further comprises allowing the central service facility to determine a wireless location technology to use.

8. The method of claim 1, wherein the step of providing the radio with data about wireless data networks further comprises transmitting data updates from the central service facility to the radio.

9. A system for communicating over a plurality of wireless data networks, the system comprising:

a software defined radio capable of being configured to operate with a plurality of wireless network services;

a radio controller for reconfiguring the radio to operate over a wireless data network;

a first database containing information about wireless data networks;

wireless location technology used to determine a location of the radio;

a frequency scanning device;

a second database containing information about a predetermined set of media broadcast channels;

wherein the wireless location technology determines a location of the radio and the controller compares the location with information contained in the first database to determine available wireless data networks; and

wherein the system uses the frequency scanning device to scan for media broadcast channels and compares results of the scan with information contained in the second database to determine a location of the radio.

10. The system of claim 9 wherein the information contained in the first database comprises coverage areas, license agreements, and radio software configuration information.

11. The system of claim 9 wherein the information contained in the second database comprises license and geographic operation information of the media broadcast channels.

12. The system of claim 9 wherein the predetermined media broadcast channels in the first database comprise information about radio broadcast channels.

13. The system of claim 11 wherein the predetermined media broadcast channels in the first database comprise information about television broadcast channels.

14. The system of claim 9 wherein the wireless location technology comprises handset-based wireless location technology.

15. The system of claim 9 wherein the wireless location technology comprises network-based wireless location technology.

16. The system of claim 9 wherein the radio controller selects a wireless location technology to determine a location of the radio.

17. The system of claim 9 further comprising a central service facility and a transceiver at the central service facility.

18. The system of claim 17 wherein the central service facility selects a wireless location technology to determine a location of the radio and transmits a command to the radio to use the selected location technology.

19. The system of claim 17 wherein the central service facility farther comprises a third database containing information about wireless data networks wherein the first database is a subset of the third database.

20. The system of claim 19 wherein the central service facility transmits a command to the radio to accept updates about wireless data networks from the third database to the first database.

21. The system of claim 9 wherein a user of the radio selects a location technology to determine a location of the radio.

22. The system of claim 9 wherein the system uses information contained in the first database to determine the most cost effective wireless data network.

23. The system of claim 9 wherein the system selects a reliable wireless data network.

24. A method for configuring a radio located on a remote mobile asset for communicating over a wireless network, the method comprising the steps of:

connecting the radio with a first database containing license and geographic operation information for a predetermined set of media broadcast channel frequencies;

connecting the radio with a second database containing information about wireless data networks;

scanning the media broadcast frequency bands to detect the predetermined set of media channels;

determining a location of the remote asset using results from detecting the predetermined set of media channels and comparing with license and geographic operation information contained in the first database;

comparing the location of the remote asset with information contained in the second database for determining available wireless data networks providing coverage at the location;

selecting a wireless data network providing coverage at the location;

configuring the radio for communicating over the wireless data network selected.

25. The method of claim 24 further comprising the remote asset communicating with a central service facility over the selected wireless data network.

26. The method of claim 25 further comprising transmitting data from the central service facility to the first database.

27. The method of claim 25 further comprising transmitting data from the central service facility to the second database.

28. The method of claim 24 wherein scanning to detect the media broadcast channels further comprises scanning to detect radio and television channels.

29. The method of claim 24 wherein selecting a wireless data network further comprises selecting a reliable wireless data network from available networks.

30. The method of claim 24 wherein selecting a wireless data network further comprises selecting a coat effective wireless data network from available networks.
