Wireless transmission technology has been around since 1891, invented by the great scientist Nikola Tesla. Wireless transmission is just like the WIFI we usually use, which USES the electric transmitter to transmit the electricity to the surrounding area in the form of radio waves. As long as the receiver is within the range of the radio waves, it can receive the electricity and provide it to the equipment for use, no longer need the wire transmission. At present, most wireless transmission technology is still in the experimental stage, so we seldom see related products in our daily life.
