9. Read and translate the text «Radio Communication» Part 2, then put the paragraphs in the correct order: Radio Communication (2)

  1. Not only was Popov’s receiver suitable for radio communication, but he also used it, with some added components, for the automatic recording of lightning discharges. This achievement, which also occurred in 1895, marked the beginning of radio meteorology. Active work on the commercial use of radio communication was undertaken in Western Europe and the USA. In 1897, Marconi established the Wireless Telegraph and Signal Company, Ltd., in England. He founded the American Marconi Company in 1899 and the Marconi International Marine Communication Company, Ltd., in 1900. In December 1901 he sent a radiotelegraph transmission across the Atlantic Ocean. A. Slaby, G. von Arco, and K. F. Braun organized the manufacture of radio-communications equipment in Germany in 1902.

  1. Other examples are the fixed service, where communication is between permanently located stations; the mobile service, where communication is between a mobile station and a land station or between mobile stations; radio broadcasting; and television. To meet industrial and official needs special services exist in some ministries and organizations. Thus, there are services for civil aviation, the railroads, river and marine transport, and such municipal agencies as the fire department, police, and health department. Another example is the use of radio for internal communication in industrial and agricultural enterprises and in some institutions. Radio communications are of great importance in the armed forces.

  1. The development of radio communications began after A. S. Popov, in 1895, and G. Marconi, in 1896, constructed sensitive receivers that were fully suitable for achieving wireless signaling—that is, for radio communication. On May 7, 1895, Popov gave the first public demonstration of the radio apparatus he had designed and of the wireless transmission of signals by it. Radio communications can thus be regarded as having originated on this date.

  1. Nowadays, radio services are the organizational-technical measures and means for establishing and maintaining the systematic functioning of radio communications. They can be classified according to, for example, their purpose, their range, and their structure. Examples of services are the earth-space service and the space service, which encompass all types of radio communications involving the use of one or more satellites or other space vehicles.
