The concept of messages being transmitted using radio waves was not conceivable in the 18th century as the existence of radio waves was not discovered until the late 19th century. In 1887, physicist Heinrich Hertz conducted experiments that proved the existence of radio waves and demonstrated that they could be used to transmit information. At that time, the understanding of radio waves and their potential uses was limited, but the discovery laid the foundation for the development of wireless communication.
