Abstract

A system for configuring a wireless module power limit comprises a wireless module having a control module configured to automatically select a power limit setting from one of a plurality of power limit settings to set a maximum output power level for the wireless module to enable an antenna coupled to the wireless module to radiate at a predetermined power level.

Claims

1. A method for configuring a wireless module power limit, comprising:

automatically selecting a power limit setting from one of a plurality of power limit settings of a wireless module to set a maximum output power level for the wireless module to enable an antenna coupled to the wireless module to radiate at a predetermined power level.

2. The method of claim 1 further comprising retrieving at least one control value indicating the power limit setting to select from a memory.

3. The method of claim 1 further comprising selecting the power limit setting to compensate for a coupling loss associated with coupling the wireless module to the antenna.

4. The method of claim 1 further comprising selecting the power limit in response to initialization of the wireless module.

5. The method of claim 1 wherein selecting the power limit setting comprises selecting the power limit setting from a plurality of power limit settings of an amplifier of the wireless module.

6. The method of claim 1 further comprising storing a control value indicating the power limit setting to select in a memory coupled to the wireless module.

7. The method of claim 1 wherein selecting the power limit setting comprises communicating a control signal from a control module of the wireless module to an amplifier of the wireless module.

8. A system for configuring a wireless module power limit, comprising:

a wireless module having a control module configured to automatically select a power limit setting from one of a plurality of power limit settings to set a maximum output power level for the wireless module to enable an antenna coupled to the wireless module to radiate at a predetermined power level.

9. The system of claim 8 wherein the selected power limit setting compensates for a coupling loss associated with coupling the wireless module to the antenna.

10. The system of claim 8 wherein the plurality of power limit settings are associated with an amplifier of the wireless module.

11. The system of claim 8 further comprising a memory storing at least one control value indicating the power limit setting to select.

12. The system of claim 8 wherein the control module is configured to select the power limit setting in response to initialization of the wireless module.

13. The system of claim 8 wherein the control module is configured to retrieve a control value from a memory indicating the power limit setting to select.

14. The system of claim 8 wherein the control module is configured to transmit a control signal to an amplifier of the wireless module for selecting the power limit setting.

15. A system for configuring a wireless module power limit, comprising:

means for automatically selecting a power limit setting from one of a plurality of power limit settings of a wireless module means to set a maximum output power level for the wireless module means to enable an antenna means coupled to the wireless module means to radiate at a predetermined power level.

16. The system of claim 15 further comprising a memory means storing at least one control value indicating the power limit setting to select.

17. The system of claim 15 wherein the selected power limit setting is configured to compensate for a coupling loss associated with coupling the wireless module means to the antenna means.

18. The system of claim 15 wherein the selecting means is configured to select the power limit setting in response to initialization of the wireless module means.

19. The system of claim 15 wherein the selecting means is configured to select the power limit setting from a plurality of power limit settings of an amplifier means of the wireless module means.
