Abstract

In one embodiment, there is provided a method comprising determining if one or more devices in a system is a conflicting device which device which conflicts with a wireless communications interface in the system by radio frequency which interferes with an operation of the wireless communications interfaces; and dynamically resolving each conflict during operation of the system. According to another embodiment, there is provided a system which includes a conflict detection unit to detect if one or more devices in the system is a conflicting device which conflicts with a wireless communications interface in the system by producing radio frequency which interferes with an operation of the wireless communications interface; and a conflict resolution unit to dynamically resolve each conflict during operation of the system.

Claims

1. A method comprising:

determining if one or more devices in a system is a conflicting device that conflicts with a wireless communications interface in the system by producing radio frequency that interferes with an operation of the wireless communications interface; and

dynamically resolving each conflict between the one or more devices in the system during operation of the system based on information corresponding to the one or more devices, the information stored in a data structure of the system and including an operating frequency, a priority, a preferred frequency, and

an electromagnetically shielded indication for the one or more devices.

2. The method of claim 1, wherein the determining comprises accessing the data structure to determine if each device operates at a frequency which overlaps with an operating frequency of the wireless communications interface.

3. The method of claim 2, wherein the determining further comprises determining a device being a conflicting device if it is not electromagnetically shielded and there is overlap.

4. The method of claim 3, wherein dynamically resolving each conflict comprises changing an operating frequency of the one or more conflicting devices so as to avoid the conflict.

5. The method of claim 4, wherein changing the operating frequency is in accordance with the priority of the devices, the operating frequency of a lower priority device been changed before changing the operating frequency of a higher priority device.

6. The method of claim 4, wherein changing the operating frequency comprises selecting a highest operating frequency for a conflicting device, which frequency avoids the conflict.

7. The method of claim 6, further comprising notifying a user if an operating frequency of a high priority device is to be changed.

8. The method of claim 7, further comprising:

receiving the user'"'"'s input on whether to change the operating frequency of the high priority device; and

selectively changing the operating frequency of the high priority device based on the user'"'"'s input.

9. A computer-readable medium having stored thereon a sequence of instructions which when executed by a processor causes the processor to perform a method comprising:

determining if one or more devices in a system is a conflicting device that conflicts with a wireless communications interface in the system by producing radio frequency that interferes with an operation of the wireless communications interface; and

dynamically resolving each conflict between the one or more devices in the system during operation of the system based on information corresponding to the one or more devices, the information stored in a data structure of the system and including an operating frequency, a priority, a preferred frequency, and

an electromagnetically shielded indication for the one or more devices.

10. The computer-readable medium of claim 9, wherein the determining comprises accessing the data structure to determine if each device operates at a frequency which overlaps with an operating frequency of the wireless communications interfaces.

11. The computer-readable medium of claim 10, wherein the determining further comprises checking if a device is electromagnetically shielded, a device being a conflicting device if it is not electromagnetically shielded and there is overlap.

12. The computer-readable medium of claim 11, wherein dynamically resolving each conflict comprises changing an operating frequency of the one or more conflicting devices so as to avoid the conflict.

13. The computer-readable medium of claim 12, wherein changing the operating frequency is in accordance with the priority of the devices, the operating frequency of a lower priority device being changed before changing the operating frequency of a higher priority device.

14. The computer-readable medium of claim 12, wherein changing the operating frequency comprises selecting a highest operating frequency for a conflicting device, which frequency avoids the conflict.

15. The computer-readable medium of claim 14, wherein the method further comprises notifying a user if an operating frequency of a high priority device is to be changed.

16. The computer-readable medium of claim 15, wherein the method further comprises:

receiving the user'"'"'s input on whether to change the operating frequency of high priority device; and

selectively changing the operating frequency based on the user'"'"'s input.

17. A system comprising:

a conflict detection unit to detect if one or more devices in the system is a conflicting device that conflicts with a wireless communications interface in the system by producing radio frequency that interferes with an operation of the wireless communication interface;

a data structure to store information for the one or more devices, the information including an operating frequency, a priority, a preferred frequency, and an electromagnetically shielded indication for each device in the system; and

a conflict resolution unit to dynamically resolve each conflict between the one or more devices in the system during operation of the system based on the information stored in the data structure corresponding to the one or more devices.

18. The system of claim 17, wherein dynamically each resolving conflict comprises changing the operating frequency of the one or more conflicting devices to avoid the conflict, devices having a lower priority being changed before devices having a higher priority are changed.

19. The system of claim 18, wherein the conflict resolution unit further to:

notify a user if a conflict cannot be resolved other than by changing an operating frequency of a high priority device; and

selectively change the operating frequency of the high priority device based on a response to the notification.

20. A system comprising:

means for determining if one or more devices in a system is a conflicting device that conflicts with a wireless communications interface in the system by producing radio frequency that interferes with an operation of the wireless communications interface; and

means for dynamically resolving each conflict between the one or more devices in the system during operation of the system based on information corresponding to the one or more devices, the information stored in a data structure of the system and including an operating frequency, a priority, a preferred frequency, and an electromagnetically shielded indication for the one or more devices.

21. The system of claim 20, wherein the means for determining further includes means for accessing the data structure to determine if each device operates at a frequency which overlaps with an operating frequency of the wireless communications interface.

22. The system of claim 21, wherein the means for determining further includes means for determining a device being a conflicting device if it is not electromagnetically shielded and there is overlap.

23. The system of claim 22, wherein the means for dynamically resolving each conflict includes means for changing an operating frequency of the one or more conflicting devices so as to avoid the conflict.

24. The system of claim 23, wherein the means for changing the operating frequency is in accordance with the priority of the devices, the operating frequency of a lower priority device been changed before changing the operating frequency of a higher priority device.

25. The system of claim 23, wherein the means for changing the operating frequency comprises selecting a highest operating frequency for a conflicting device, which frequency avoids the conflict.

26. The system of claim 25, further comprising means for notifying a user if an operating frequency of a high priority device is to be changed.

27. The system of claim 26, further comprising:

means for receiving the user'"'"'s input on whether to change the operating frequency of the high priority device; and

means for selectively changing the operating frequency of the high priority device based on the user'"'"'s input.
