Abstract: According to various embodiments, an electronic device may comprise a first communication module, a second communication module, and a processor. The processor may check the strength of a signal received from an external electronic device by using the communication module or the second communication module. If the strength satisfies a first designated condition, the processor may transmit first data, among data to be transmitted to the external electronic device, to the external electronic device by using a first designated frequency corresponding to the first communication module, and may transmit second data, among the data, to the external electronic device by using a second designated frequency corresponding to the second communication module. If the strength satisfies a second designated condition, the processor may check the position of the external electronic device with regard to the electronic device by using the first designated frequency, and may transmit the data to the external electronic device, at least on the basis of the position, by using the second designated frequency. If the strength satisfies a third designated condition, the processor may transmit the data to the external electronic device through the first communication module and the second communication module by using one corresponding designated frequency among the first designated frequency and the second designated frequency. Various other embodiments are possible.
