Abstract: A method for operating a plurality of ultra-wide band (UWB) channels by a first electronic device is provided. The method includes receiving a Bluetooth low energy (BLE) advertisement message including information about an UWB channel, from a second electronic device, identifying whether a plurality of UWB channels are operated, based on the information about the UWB channel, and identifying a UWB channel to be used for communication with the second electronic device, based on the information about the UWB channel. The information about the UWB channel may include flag information indicating an area and channel information indicating a UWB channel for the indicated area.
