1. An electronic device comprising:
ultra-wide band (UWB) circuitry;
memory, storing one or more instructions, comprising one or more storage media; and
at least one processor comprising circuitry configured to control the UWB circuitry,
wherein the one or more instructions, when executed by the at least one processor, individually or collectively, cause the electronic device to:
transmit, through the UWB circuitry operating in a first transmission mode for a first period, a first frame by transmitting a first signal for a first field and a second signal for a second field including reference information;
receive, through the UWB circuitry, a first reflected signal related to the first signal and a second reflected signal related to the second signal, respectively, caused by an external object;
based on a state of the reference information identified from the second reflected signal being a first state, obtain information on the external object based on the first reflected signal; and
based on the state of the reference information being a second state, transmit a second frame by transmitting a third signal for the first field and a fourth signal for the second field, through the UWB circuitry operating in a second transmission mode for a second period different from the first period, switched from the first transmission mode.
