Abstract: An electronic device may include: a communication module that supports ultra-wideband communication; a memory that stores correction values respectively corresponding to a plurality of data ranges divided according to a specified condition, in relation to data for positioning of an external electronic device; a processor operatively connected to the communication module and the memory; and a location determination module operatively connected to the processor. The location determination module may be configured to: acquire a phase difference of arrival of a signal calculated on the basis of the signal received from the external electronic device via the communication module; determine a data range corresponding to the acquired phase difference of arrival of the signal from among the plurality of data ranges; and calculate the angle of arrival of the signal by using a correction value corresponding to the determined data range from among the correction values. Various other embodiments are possible.

Abstract: An electronic device is provided. The electronic device includes an antenna to transmit or receive a signal of a specific frequency band, a wireless local area network (WLAN) communication module, and an ultra-wide band (UWB) communication module, wherein the UWB communication module may be configured to transmit a first signal notifying that the specific frequency band is to be used to the WLAN communication module, and use the specific frequency band, wherein the WLAN communication module may be configured to terminate, in case that the specific frequency band is being used, a use of the specific frequency band within a preset time in response to reception of the first signal, and transmit, when the use of the specific frequency band is terminated, a second signal indicating whether the specific frequency band is used by the WLAN communication module to the UWB communication module.
