A backscattering method for an Internet-of-things (IoT) device includes a frequency-splitting (FS)-simultaneous wireless information and power transfer (SWIPT) wireless communication system. The backscattering method includes collecting energy by simultaneously receiving power having a first frequency, receiving data having a first frequency band, and decoding the data; determining a second frequency band to uplink; and transmitting tag information in the second frequency band using the power having the first frequency in a backscattering manner.
