Abstract

Different target transmit powers are determined for different wireless transmissions from a wireless device, the different transmissions having different security requirements. For example, the security requirements of a particular transmission may include a security ranking of a device to which one or more frames carried by the particular transmission are addressed. In another example, the security requirements of a particular transmission may include the confidentiality of data carried by the particular transmission.

Claims (39)

1. A device comprising:

a processor;

a memory to store executable code which, when executed by said processor, determines a target transmit power for a wireless transmission based, at least in part, on a security ranking of a device to which one or more frames carried by said wireless transmission are addressed; and

a wireless transmitter to transmit said wireless transmission.

2. The device of claim 1 , wherein said target transmit power is lower for a wireless transmission carrying one or more frames addressed to a device having a higher security ranking than for a wireless transmission carrying one or more frames addressed to a device having a lower security ranking.

3. The device of claim 1 , wherein said device is a mobile device.

4. The device of claim 1 , wherein said device includes smart card reader functionality.

5. The device of claim 1 , wherein said device is a headset.

6. The device of claim 1 , wherein said wireless transmitter is compatible with a Bluetooth standard.

7. A device comprising:

a processor;

a memory to store executable code which, when executed by said processor, determines a target transmit power for a wireless transmission the based, at least in part, on confidentiality of encrypted data carried by said wireless transmission; and

a wireless transmitter to transmit said wireless transmission.

8. The device of claim 7 , wherein said target transmit power is lower for a wireless transmission carrying encrypted data of higher confidentiality than for a wireless transmission carrying encrypted data of lower confidentiality.

9. The device of 7 , wherein said device is a mobile device.

10. The device of claim 7 , wherein said device includes smart card reader functionality.

11. The device of claim 7 , wherein said device is a headset.

12. The device of claim 7 , wherein said wireless transmitter is compatible with a Bluetooth standard.

13. A device comprising:

a processor;

a memory to store executable code which, when executed by said processor, determines different target transmit powers for different wireless transmissions having different security requirements;

a wireless transmitter to transmit said different wireless transmissions; and

a wireless receiver, wherein said executable code, when executed by said processor, increases a target transmit power for a particular wireless transmission in the absence of receipt of a valid response by said wireless receiver from a device for which said particular wireless transmission is intended.

14. The device of claim 13 , wherein said device is a mobile device.

15. The device of claim 13 , wherein said device includes smart card reader functionality.

16. The device of claim 13 , wherein said device is a headset.

17. The device of claim 13 , wherein said wireless transmitter is compatible with a Bluetooth standard.

18. A method in a wireless-enabled device, the method comprising:

determining a target transmit power of a wireless transmission based, at least in part, on a security ranking of a device to which one or more frames carried by said wireless transmission are addressed; and

transmitting said wireless transmission.

19. The method of claim 18 , wherein determining said target transmit power of said wireless transmission includes determining a lower target transmit power for a wireless transmission carrying one or more frames addressed to a device having a higher security ranking than for a wireless transmission carrying one or more frames addressed to a device having a lower security ranking.

20. A method in a wireless-enabled device, the method comprising:

determining a target transmit power of a wireless transmission based, at least in part, on confidentiality of encrypted data carried by said wireless transmission; and

transmitting said wireless transmission.

21. The method of claim 20 , wherein determining said target transmit power of said wireless transmission includes determining a lower target transmit power for a wireless transmission carrying encrypted data of higher confidentiality than for a wireless transmission carrying encrypted data of lower confidentiality.

22. A method in a wireless-enabled device, the method comprising:

determining different target transmit powers for different wireless transmissions having different security requirements;

transmitting said different wireless transmissions; and

increasing a target transmit power of a particular wireless transmission in the absence of a valid response from a device for which said particular wireless transmission is intended.
