A radio frequency identification (RFID) interrogator for determining a bandwidth of a backscattering signal to be backscattered by an RFID tag and a method of operating the same are provided. The RFID interrogator senses a predetermined frequency band to determine whether the predetermined frequency band has been occupied and determines a sensing result. The RFID interrogator further controls the bandwidth of the backscattering signal in response to the sensing result.
