Abstract

A device and method are provided that reduce interference between a wireless communication device and a speaker. Generally speaking, a microphone input is monitored for detecting noise created by the interference. If noise is detected, a power transmission level of the wireless device is reduced from a standard power transmission level.

Claims (33)

1. A method for reducing an interference between a wireless communication device, the wireless communication device having a first speaker, and a second speaker in a proximity of the wireless communication device, the method comprising

monitoring a microphone input of the wireless communication device for detecting a noise from the second speaker, the noise caused by the interference between the wireless communication device and the second speaker; and

reducing a power transmission level of the wireless communication device from a standard power transmission level in response to a detection of the noise.

2. The method of claim 1 , further comprising:

initiating a predefined event;

monitoring the predefined event to determine when a predefined event threshold is reached; and

returning the power transmission level of the wireless communication device to the standard power transmission level when said predefined event threshold is reached.

3. The method of claim 2 , wherein the power transmission level is reduced to a lower power transmission level.

4. The method of claim 2 , wherein the power transmission level is reduced by not transmitting data from the wireless communication device.

5. The method of claim 2 , wherein the initiating the predefined event comprises starting a timer and the predefined event threshold is a predefined duration of time.

6. The method of claim 2 , wherein the initiating the predefined event comprises determining a geospatial position of the wireless communication device and the predefined event threshold is a predefined distance traveled.

7. The method of claim 6 , wherein the geospatial position and predefined distance traveled are determined using at least one of an accelerometer, global positioning system and a motion sensor.

8. The method of claim 6 , wherein the initiating the predefined event further comprises starting a timer and the predefined event threshold further includes a predefined duration of time.

9. The method of claim 1 , further comprising: determining that data retransmissions are acceptable before reducing the power transmission level.

10. The method of claim 3 , wherein the determining that data retransmissions are acceptable comprises interpreting a Quality of Service indicator.

11. A wireless communication device, the wireless communication device having a first speaker, configured to reduce interference with a second speaker, the wireless communication device comprising:

a microphone;

a noise detection unit monitoring the microphone to detect a noise from the second speaker in a proximity of the wireless communication device, the noise caused by an interference between the wireless communication device and the second speaker; and

a power controller configured to reduce a power transmission level of the wireless communication device in response to a detection of the noise by the noise detection unit.

12. The wireless communication device of claim 11 , further comprising:

an event unit configured to trigger an event in response to the detection of the noise by the noise detection unit; and

an event monitor configured to detect when the triggered event reaches a predefined event threshold and instruct the power controller to return the power transmission level of the wireless communication device to a standard power transmission level.

13. The wireless communication device of claim 12 , further including a data a determination unit configured to determine if data retransmissions are acceptable before reducing the power transmission level.

14. The wireless communication device of claim 12 , wherein the data determination unit determines that data retransmissions are acceptable in accordance with a Quality of Service indicator.

15. The wireless communication device of claim 12 , wherein the power controller is configured to reduce the power transmission level to a lower power transmission level.

16. The wireless communication device of claim 12 , wherein the power controller is configured to reduce the power transmission level by not transmitting data from the wireless communication device.

17. The wireless communication device of claim 12 , wherein the event unit comprises a timer and the predefined event threshold is a predefined duration of time.

18. The wireless communication device of claim 12 , wherein the event unit comprises a geospatial positioning device configured to determine a geospatial position of the wireless communication device and the predefined event threshold is a predefined distance traveled.

19. The wireless communication device of claim 18 , wherein the geospatial positioning device is at least one of an accelerometer global positioning system and a motion sensor.

20. The wireless communication device of claim 18 , wherein the event unit further comprises a timer and the predefined event threshold further includes a predefined duration of time.

21. A non-transitory data storage medium comprising instructions which, when executed on a wireless communication device, the wireless communication device having a first speaker, cause the wireless communication device to facilitate reducing an interference with a second speaker in a proximity of the wireless communication device by implementing:

monitoring a microphone input of the wireless communication device for detecting a noise from the second speaker, the noise caused by the interference between the wireless communication device and the second speaker; and

reducing a power transmission level of the wireless communication device from a standard power transmission level in response to a detection of the noise.
