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: A method and an electronic device for ranging are provided. An ultra-wideband (UWB) signal is received from an external device through a first antenna. A communication state between the external device and the electronic device is identified using information about communication quality included in the UWB signal. A signal received through a second antenna is identified by decoding the received signal based on the identified communication state. A distance between the electronic device and the external device is determined based on whether the received signal is a low frequency (LF) signal.
