Abstract

A process for controlling radio transmission and/or reception to enforce certain constraints with either single or multiple radio communication is disclosed. In one embodiment, the enforcement control may be by the corporate administrator (such as an Information Technology (IT) department) that is responsible for the company'"'"'s wireless devices. In other embodiments, the enforcement control may be by a regulatory group having governmental control over wireless communication. In yet another embodiment, the enforcement control might be by a provider group, such as a provider of a local private or semi-private wireless network desiring certain controls over the users of the network.

Claims

1. A method of using an SDR-enabled wireless device, the method comprising:

a) initiating a request for wireless communication using the SDR;

b) determining whether the requested wireless communication is allowed; and

c) enabling the requested wireless communication when the requested wireless communication is within predetermined allowed criteria.

2. The method of claim 1, further comprising:

a) initiating a request for simultaneous wireless communication using a second SDR;

b) determining whether the requested simultaneous wireless communication is allowed; and

c) enabling the requested simultaneous wireless communication when the requested simultaneous wireless communication is within second predetermined allowed criteria.

3. The method of claim 1, wherein determining whether the requested wireless communication is allowed comprises receiving criteria about when wireless communication is allowed from a source upon initial communication with the source and comparing the requested wireless communication to the criteria.

4. The method of claim 2, wherein determining whether the requested simultaneous wireless communication is allowed comprises receiving criteria about when simultaneous wireless communication is allowed from a source upon initial communication with the source and comparing the requested simultaneous wireless communication to the criteria.

5. The method of claim 1, further comprising obtaining the allowed criteria from a corporate IT group.

6. The method of claim 1, further comprising obtaining the allowed criteria from a service provider.

7. The method of claim 1, further comprising obtaining the allowed criteria from a regulatory group.

8. The method of claim 1, further comprising allowing unrestricted wireless communication when the requested wireless communication is within the predetermined allowed criteria.

9. The method of claim 1, further comprising allowing restricted wireless communication when the requested wireless communication is not within the predetermined allowed criteria.

10. The method of claim 9, further alerting a user of the wireless device that wireless communication is restricted to certain constraints.

11. The method of claim 2, further comprising allowing restricted wireless communication when the requested wireless communication is not within the predetermined allowed criteria.

12. The method of claim 2, further comprising automatically blocking redistribution of a wireless connection when the requested simultaneous wireless communication is not within second predetermined allowed criteria.

13. The method of claim 2, further comprising automatically disabling a second SDR when the requested simultaneous wireless communication is not within second predetermined allowed criteria.

14. The method of claim 7, wherein obtaining the allowed criteria from a regulatory group comprises obtaining the allowed criteria automatically upon wireless communication with a network that is regulated by the regulatory group.

15. The method of claim 14, wherein obtaining the allowed criteria from a regulatory group comprises allowing a user to enter a country code into the wireless device.

16. The method of claim 14, wherein obtaining the allowed criteria from a regulatory group comprises automatically entering GPS data into the wireless device.

17. A method of using an SDR-enabled wireless device, the method comprising:

a) communicating with a wireless network with a first SDR;

b) thereafter initiating a request for simultaneous wireless communication using multiple SDRs;

c) determining whether the requested simultaneous wireless communication is allowed; and

d) enabling the requested simultaneous wireless communication when the requested simultaneous wireless communication is within predetermined allowed criteria.

18. The method of claim 17, further comprising automatically disabling at least one second SDR when the requested simultaneous wireless communication is not within second predetermined allowed criteria.

19. A computer system, comprising:

programmable circuitry;

software encoded on at least one computer-readable medium to program the programmable circuitry to implement a software defined radio; and

a verification module encoded to enable wireless communication when the wireless communication is within predetermined allowed criteria.

20. The system of claim 19, wherein the verification module is encoded to enable simultaneous wireless communication when the simultaneous wireless communication is within the predetermined allowed criteria.
