Abstract: According to various embodiments, an electronic device may comprise an ultra-wideband (UWB) communication circuit, a Wi-Fi communication circuit and a processor controlling the UWB communication circuit and the Wi-Fi communication circuit. The processor may be configured to identify an operation channel of the UWB communication circuit, identify a communication band of the Wi-Fi communication circuit, overlapping the operation channel of the UWB communication circuit, and when the communication band overlapping the operation channel is activated, determine whether to simultaneously perform Wi-Fi communication through the activated communication band and UWB communication through the operation channel. Other various embodiments are possible as well.

Abstract: Disclosed herein are electronic devices and methods for operating the electronic devices according to various embodiments. Such electronic devices may include: a communication circuit configured to perform short-range wireless communication through one link or multiple links generated between an external electronic device and the electronic devices and a processor operatively connected to the communication circuit. The processor may identify the state of multiple links, based on information transmitted by the external electronic device, select one mode from a first mode in which data is divided and transmitted through the multiple links and a second mode in which identical data is transmitted through the multiple links, based on the state of the multiple links, and control the communication circuit so as to transmit the data to the external electronic device through the selected mode. Various other embodiments are possible.

Abstract: An electronic device includes a wireless communication module configured to transceive a wireless signal, a processor operatively connected to the wireless communication module, and a memory electrically connected to the processor and configured to store instructions executable by the processor, wherein, when the instructions are executed by the processor, the processor is configured to determine whether roaming is triggered by a roaming trigger while forming a plurality of links with and connected to an access point (AP), determine a state of the plurality of links by responding to the roaming trigger, and differentiate and perform roaming operations according to the state of the plurality of links. In addition, various embodiments may be possible.

Abstract: In an electronic device and/or an operating method of the electronic device, the electronic device may include: a communication circuit configured to perform short-range wireless communication through a first frequency band and/or a second frequency band lower than the first frequency band; and a processor, wherein the processor may be configured to identify whether a channel in the first frequency band is a non-preferred scanning channel (non-PSC), based on reduced neighbor report (RNR) information included in a signal received through the second frequency band from an external electronic device, determine a quality of a signal to be received through the first frequency band, based on transmit power control (TPC) information received from the external electronic device upon identifying that the channel in the first frequency band is the non-PSC, and determine whether to perform an operation of scanning the non-PSC, based on whether a quality of a signal to be transmitted through the first frequency band sati
