Abstract
According to various embodiments, a wireless power transmission device comprises: a first-scheme communication circuit; a power source for generating a source signal; a power transmission circuit for forming an RF wave on the basis of the source signal; and a control circuit, wherein the control circuit can be configured to receive, from an electronic device supporting first-scheme communication and second-scheme communication, a communication signal including information on a communication environment according to the second-scheme communication through the first-scheme communication circuit, and to control, on the basis of the information on the communication environment according to the second-scheme communication, the frequency of the source signal generated by the power source and/or the transmission strength of the RF wave. Other various embodiments are possible.
