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
