Historical Background
Since the early 1960s, the Soviet Union implemented mobile communication technology through the wireless telephone system “Altai,” which entered operational service. It is important to note that subscriber equipment of that period differed significantly from modern mobile phones. It had substantial weight and lacked contemporary portability and design. These were complete radio communication units installed in vehicles, often occupying significant space in the passenger compartment and trunk. Nevertheless, such equipment enabled wireless connections to the public telephone network in fully automatic mode.
The original “Altai” units, similar to foreign counterparts of the time (U.S. mobile data networks), were primarily installed in vehicles of government officials and senior executives, or deployed in remote areas. By the late 1980s, the “Altai” system underwent significant upgrades, including solving the roaming problem and implementing automatic frequency switching without loss of connection. The new communication system was named “Volemot,” formed from the names of the cities involved in its development: Voronezh, Leningrad, Molodechno, Ternopil. Subscriber equipment production was established at the “Sputnik” radio plant in Molodechno and the “Kvazar” Design Bureau in Nizhny Novgorod.
As a result of the restructuring period and subsequent changes, “Volemot” was introduced only in a few major cities of the USSR. Nevertheless, despite limited competition from more advanced forms of mobile communication, “Volemot” continued to operate at least until the 2010s in the cities of Samara and Syzran. The unmodernized “Altai” system continued to be used in Novosibirsk for a long time, serving the city’s emergency and utility services.
