SYSTEM AND METHOD OF CONTROLLING TRANSMIT POWER FOR MOBILE WIRELESS DEVICES WITH MULTI-MODE OPERATION OF ANTENNA
A radio control system in a communication device is disclosed, the radio control system comprising: (a) a sensor capable of detecting a change in use mode of said device; (b) a power controller connected to said sensor to determine a power configuration based on the use mode; and (c) a power regulator connected to said power controller to apply the power configuration to a transmitted signal. A method of controlling a power configuration in a communication device is disclosed, comprising the steps of: (a) detecting a use mode; (b) changing the power configuration as a function of the use mode; and (c) communicating at the changed power configuration. A radio control system in a communication device is disclosed, comprising: (a) a sensor capable of detecting a change in use mode of said device; (b) a radio controller connected to said sensor to determine a radio configuration based on the use mode; and (c) a radio configuration module connected to said radio controller to apply the radio configuration to the transmitted signal.
1 . An apparatus comprising:
a wireless communication device configured to automatically adjust the power level of its output signal based on whether the wireless telephone is in speakerphone mode.
2 . The apparatus of claim 1 wherein the power level is adjusted during a call.
3 . The apparatus of claim 1 wherein the power level is adjusted by setting a maximum output power level.
4 . The apparatus of claim 1 wherein the power level is adjusted by setting a minimum transmit power level.
5 . The apparatus of claim 1 wherein the wireless communication device is a cellular telephone.
6 . The apparatus of claim 1 wherein the communication device is further configured to adjust a transmission rate in conjunction with adjusting the power level of the output signal.
7 . The apparatus of claim 1 wherein the communication device is further configured to adjust an antenna radiating pattern in conjunction with adjusting the power level of the output signal.
8 . The apparatus of claim 1 wherein the communication device is further configured to adjust an antenna gains in conjunction with adjusting the power level of the output signal.

12 . A wireless communication device comprising:
a sensor configured to detect, during a call conducted through the communication device, that the communication device has entered a speakerphone mode during the call; and
a power controller configured to:
use a first transmit power setting upon initiation of the call, and
automatically switch, during the call, to a second transmit power setting, different than the first transmit power setting, in response to the sensor detecting that the communication device has entered the speakerphone mode.
13 . The communication device of claim 12 wherein the first transmit power setting is lower than the second transmit power setting.
14 . The communication device of claim 12 wherein the first transmit power setting is selected to be within a predetermined transmit power limit for when the wireless communication device is near the user's head.
15 . The communication device of claim 14 wherein the second transmit power setting is above the predetermined transmit power limit.
16 . The communication device of claim 12 wherein the sensor and the power controller are parts of a cellular telephone.
