Abstract: An electronic device according to various embodiments of the present invention may comprise a transmission module including a first transmission module and a second transmission module, and a processor. The processor may feedback-receive a transmission power of the first transmission module, calculate a difference value between a target transmission power and the transmission power of the first transmission module, determine a state of the first transmission module on the basis of the difference value, and turn off a transmission operation of the first transmission module and activate a transmission operation of the second transmission module in accordance with the determination that the state of the first transmission module is abnormal. Various other embodiments are possible.
