摘要:
A radio control system in a wireless communication device includes a sensor operable to detect a change in a use mode of the wireless communication device during a communication session according to a pre-determined list of conditions, the use mode being one of a plurality of use modes that the communication device can operate in. The radio control system also includes a power controller connected to the sensor, that is operable to determine a power configuration according to the user mode detected. The power configuration is adjusted to balance the radio frequency coverage of a signal to be transmitted and the SAR. Of the radiation absorption. Each use mode is a different scenario in which the wireless communication device can be used.
