Abstract: An electronic device using a millimeter wave, according to various embodiments, includes a communication circuit and at least one processor. The at least one processor can be configured to: control the communication circuit so that a first millimeter wave signal is output at a first strength; use the communication circuit so that the first millimeter wave signal receives a first reflection signal reflected by an object; confirm whether the object is positioned within a first distance from the electronic device; determine the strength of a second millimeter wave signal to be a second strength corresponding to a second distance between the electronic device and the object, the second distance being shorter than the first distance; and control the communication circuit so that the second millimeter wave signal is output at the determined second strength.

Abstract: An electronic device includes: a UI; a wireless communication circuit configured to wirelessly communicate with an external electronic device by using a short-range wireless communication protocol; a processor; and a memory. The memory stores instructions, which when executed, cause the processor to receive first data from the external electronic device at a first time through a wireless communication channel by using the wireless communication circuit, receive second data from the external electronic device at a second time after the first time through the wireless communication channel by using the wireless communication circuit, compare a first reception state related to the first data and a second reception state related to the second data, and transmit, to the external electronic device, a request for change from a first mode to a second mode by using the wireless communication circuit, based on a result of the comparing.
