In 1876, Alexander Graham Bell, using copper cable, performed the first in the history of the transmission of human speech. The same scholar, four years later, its first wireless transmission of human speech, using for this purpose the light. The device he built was named fotofon and for many years attracted considerable interest of researchers.

At about the same time, the German inventor Heinrich Rudolf Hertz discovered the waves that the emissions could be captured by a set at a distance receiver. A few years later, Guglielmo Marconi sent the waves at a distance of several kilometers and called them radio. Radio quickly took the place of the aforementioned fotofon. In contrast, light, radio waves may be freely transmitted under conditions and in areas where the light transmission was difficult or impossible.

Quickly began to appear the first proposals for the use of the properties discovered radio waves. One option, already in 1891, was the launch of wireless telephony ATS1. First developed applications were used for maritime communications. At the beginning of all such news were accepted very reluctantly, but after the disaster of the Titanic interest in both communication between ships at sea between the ship and the port has grown very rapidly
