Problems solved by technology

It is necessary to modulate the main frequency to transmit signals by radio, so that the main frequency is more than 10 times higher than the transmitted data, so the driving circuit for transmitting the main frequency and the demodulation circuit for receiving are more complicated and power-consuming
Furthermore, the longer the wireless signal transmission distance, the greater the transmission power will be required, but the long transmission distance is prone to interference or signal distortion due to the Doppler effect
