The present invention relates to a backscatter communication using a wireless Wi-Fi signal. The present invention relates to a synchronization method for synchronizing backscatter data by a frame unit and transmitting it when a tag device receives a wireless signal from a wireless AP and transmits backscatter data to a terminal device. The tag device detects the start point of a frame and performs a state change according to a transmission data stat, generates the backscatter data synchronized by the frame unit, and transmit it to a terminal device. So, the terminal device can receive synchronized data and lower data transmission error even when a frame transmission period is not constant on a wireless AP side, and can increase the SNR of the received signal by receiving the synchronized signal, and can transmit one data symbol for each frame, and can perform high-speed data transmission.
