May 7 – Radio Day

May 7th went down in the history of world science and technology as the Birthday of Radio.

It was on this day in 1895, at a meeting of the Russian Physico-Chemical Society, that Russian physicist Alexander Stepanovich Popov gave a report and demonstration of the world's first radio receiver, which he created, carrying out the first radio communication session.

In July 1897, Popov, in a letter to the newspaper Novoye Vremya, noted: "The credit for the discovery of the phenomena that served Marconi belongs to Hertz and Branly, then there is a whole series of applications started by Minchin, Lodge and many after them, including me, and Marconi was the first to have the courage to take a practical stand..."

The first irregular radio broadcasts in Russia began in 1919 from the Nizhny Novgorod Radio Laboratory, and from 1920 from experimental radio broadcasting stations in Moscow and Kazan.

The formation and popularization of radio broadcasting in the country in the 1920s was facilitated by the mass amateur radio movement, which began to develop after the opening of the Comintern radio station in Moscow in 1922. Regular radio broadcasting began on November 23, 1924, when the first issue of the radio newspaper was broadcast.

Since 1929, regular foreign broadcasting began from Moscow - broadcasting radio programs to foreign countries.

The invention of radio marked the beginning of the development of information technology. It became the basis for the creation of navigation systems, mobile communications, wireless data exchange networks and the Internet.

Radio Day became an official annual public holiday in 1945, on the fiftieth anniversary of the invention of radio, when, taking into account the role of radio in the cultural and political life of society and in the defense of the country, the USSR government adopted a corresponding resolution. Therefore, today this date is a holiday for workers in all communications sectors.

By the Decree of the Presidium of the Supreme Soviet of the USSR dated October 1, 1980, "On holidays and memorable days," May 7 was included in the list of holidays as "Radio Day, a holiday for workers in all communications sectors."

As part of a structured system for monitoring and managing engineering systems of buildings and structures (CMIS) of the facility, the IC GOChS "BASIS" creates a communication and management subsystem in crisis situations (CCS) in accordance with GOST R 22.1.17-20.16.
