In the late 1880s a previously unknown type of radiation was discovered - radio waves. It was found to have the same nature as light, but with a greater wavelength. Various physicists and technicians investigated whether radio waves could be used to transmit signals. Ferdinand Braun contributed to wireless signal transfer technology in several ways. In the late 1890s, he developed the electronics in transmitters to reduce signal weakening and disruptions between different transmitters.
