Abstract

Different target transmit powers are determined for different wireless transmissions from a wireless device. The target transmit power of a wireless transmission may depend upon whether any transmitters other than the device to which the wireless transmission is to be sent are within range of the sending wireless device. The target transmit power of a wireless transmission may be based, at least in part, on a current location of a device to which one or more frames carried by the wireless transmission are addressed. The target transmit power of a wireless transmission may be based, at least in part, on confidentiality of data carried by the wireless transmission.

Claims

1. A method in a first wireless device, the method comprising:

determining a target transmit power of a wireless transmission, wherein one or more frames to be carried by said wireless transmission are addressed to a second wireless device and include voice data of a telephone call, said target transmit power determined based, at least in part, on confidentiality of said voice data of said telephone call, said confidentiality depending on an identity of a participant in said telephone call who is not using said first wireless device or said second wireless device; and

transmitting said wireless transmission to said second wireless device.

2. The method of claim 1, wherein said first wireless device comprises a mobile device and said second wireless device comprises a headset.

3. The method of claim 1, wherein said wireless transmission is compatible with a Bluetooth standard.

4. A first wireless device comprising:

a processor;

a memory to store executable code which, when executed by said processor, determines a target transmit power of a wireless transmission, wherein one or more frames to be carried by said wireless transmission are addressed to a second wireless device and include voice data of a telephone call, said target transmit power determined based, at least in part, on confidentiality of said voice data of said telephone call, said confidentiality depending on an identity of a participant in said telephone call who is not using said first wireless device or said second wireless device; and

a wireless transmitter to transmit said wireless transmission to said second wireless device.

5. The first wireless device of claim 4, wherein said wireless transmitter is compatible with a Bluetooth standard.

6. The first wireless device of claim 4, wherein said first wireless device comprises a mobile device and said second wireless device comprises a headset.

7. A non-transitory computer-readable medium having computer-executable instructions which, when executed by a processor of a first wireless device, result in:

determining a target transmit power of a wireless transmission, wherein one or more frames to be carried by said wireless transmission are addressed to a second wireless device and include voice data of a telephone call, said target transmit power determined based, at least in part, on confidentiality of said voice data of said telephone call, said confidentiality depending on an identity of a participant in said telephone call who is not using said first wireless device or said second wireless device.

8. The non-transitory computer-readable medium of claim 7, wherein said first wireless device comprises a mobile device and said second wireless device comprises a headset.

9. The non-transitory computer-readable medium of claim 7, wherein said wireless transmission is compatible with a Bluetooth standard.
