In the past years of nineteenth century have been registered a several significant discoveries and contrivances that caused development of wireless telegraphy and evolution of further branchs of learning simultaneously.

• In the 1886 the German physicist Heinrich Hertz proved the existence of electromagnetic waves. On this evidence began to develop the wireless telegraphy and later radiotechnique.

• From the 1893 Nikola Tesla using so called ,Tesla´s steams for wireless transformation of reports.

• The Guglielmo Marchese Marconi was the first one who emited Morse´s signs wireless to several hundred metres. In the first time he broadcasted the radio siqnals in 1894. In the 1901 he realized a wireless broadcasting over the Atlantic Ocean.

• The Russian electrical engineer A. S. Popov showed to public radio-telegraphic transfer. In the 1897 he succeeded in transmision between mainland and ship to 5 Km distances.

• In the 1897 Karl Ferdinand Braun contributed for initial development of wireless telegraphy, he stopped closed osillatory circumference.

• In the 1904 a Slovak native Jozef Murgaš obtained two patents from the U S Patent Office for wireless broadcasting. In the 1905 wireless telegraphy with its own system broadcasting and receiving (tone-system) attained connection up to 200 Km distances. He obtained 12 American patents in branch of wireless telegraphy.
