Device and method for controlling power in mobile terminal

摘要

A device and a method for controlling a transmission power in a mobile terminal are provided. The device includes an antenna set in an optimized state, a memory including a power control table that includes transmission power control data for satisfying a Specific Absorption Rate (SAR) standard in a state where efficiency of the antenna is optimized, a sensor for detecting a distance between the mobile terminal and a user, a controller for receiving distance data from the sensor and for outputting transmission power control data corresponding to the distance data by referring to the power control table, and a power amplifier connected between a transmitter and the antenna for controlling transmission power of a signal according to the transmission power control data and for outputting the signal to the antenna.

1. A method for controlling a transmission power in an electronic device, the method comprising:
detecting, via a sensor operatively coupled with the electronic device, a distance between a user and the electronic device, the electronic device set to receive a reception signal transmitted using a first power and to transmit a transmission signal using a second power; adjusting the second power to produce a third power based at least in part on the distance; and transmitting the transmission signal using the third power if the distance falls into a specified range.
