Abstract

In one embodiment, a method for controlling antenna use in a computing device comprises determining which wireless transceiving devices are active, and if multiple wireless transceiving devices are active, disabling transmission/reception diversity such that each wireless transceiving device may only use one respective antenna.

Claims

1. A method for controlling antenna use in a computing device, the method comprising:

determining which wireless transceiving devices are active; and

if multiple wireless transceiving devices are active, disabling transmission/reception diversity such that each wireless transceiving device may only use one respective antenna.

2. The method of claim 1, wherein determining which wireless transceiving devices are active comprises using a basic input-output system of the computing device.

3. The method of claim 1, wherein disabling transmission/reception diversity comprises providing a transceiving device status accessible by transceiving device drivers of the computing device.

4. The method of claim 3, wherein providing a transceiving device status comprises providing a transceiving device status to an operating system of the computing device.

5. The method of claim 3, wherein providing a transceiving device status comprises updating a look-up table accessible by the transceiving device drivers.

6. The method of claim 1, further comprising providing a default antenna identification that indicates to transceiving device drivers which antenna to use.

7. The method of claim 1, further comprising selecting a default antenna using a transceiving device driver.

8. The method of claim 1, wherein disabling transmission/reception diversity comprises providing a control signal to a transceiving device driver that indicates which antenna the transceiving device is to use.

9. The method of claim 8, further comprising selecting an antenna using a transceiving device driver according to the control signal.

10. The method of claim 1, wherein disabling transmission/reception diversity comprises controlling a physical switch associated with an antenna.

11. The method of claim 1, further comprising controlling antenna use to reduce interference.

12. The method of claim 11, wherein controlling antenna use comprises controlling antenna use such that an antenna used by a first wireless technology is separated from an antenna used by a second wireless technology that is relatively distant from the first wireless technology antenna.

13. A system for controlling antenna use in a computing device, the system comprising:

means for determining which wireless transceiving devices are active; and

means for disabling transmission/reception diversity such that each wireless transceiving device may only use one respective antenna if multiple wireless transceiving devices are active.

14. The system of claim 13, wherein the means for determining which wireless transceiving devices are active comprises a basic input-output system of the computing device.

15. The system of claim 13, wherein the means for disabling transmission/reception diversity comprises means for providing a transceiving device status accessible by transceiving device drivers of the computing device and that indicates to the transceiving device drivers which antenna to use.

16. The system of claim 13, wherein the means for disabling transmission/reception diversity comprises means for providing a control signal to a transceiving device driver that indicates which antenna the transceiving device is to use.

17. The system of claim 13, wherein the means for disabling transmission/reception diversity comprises means for controlling a physical switch associated with an antenna.

18. The system of claim 13, further comprising means for controlling antenna use such that an antenna used by a first wireless technology is separated from an antenna used by a second wireless technology that is relatively distant from the first wireless technology antenna.

19. A computing device for controlling antenna use in a computing device, the computing device comprising:

logic configured to determine which wireless transceiving devices are active; and

logic configured to disable transmission/reception diversity such that each wireless transceiving device may only use one respective antenna when multiple wireless transceiving devices are active.

20. The computing device of claim 19, wherein the logic configured to determine which wireless transceiving devices are active comprises logic of a basic input-output system of the computing device.

21. The computing device of claim 19, wherein the logic configured to disable transmission/reception diversity comprises logic configured to provide a transceiving device status accessible by transceiving device drivers of the computing device and that indicates to the transceiving device drivers which antenna to use.

22. The computing device of claim 19, wherein the logic configured to disable transmission/reception diversity comprises logic configured to provide a control signal to a transceiving device driver that indicates which antenna the transceiving device is to use.

23. The computing device of claim 19, wherein the logic configured to disable transmission/reception diversity comprises logic configured to control a physical switch associated with an antenna.

24. The computing device of claim 19, further comprising logic configured to control antenna use such that an antenna used by a first wireless technology is separated from an antenna used by a second wireless technology that is relatively distant from the first wireless technology antenna.
