The Altai mobile telephone system is the pre-cellular 0G radiotelephone service that was first introduced in the Soviet Union in 1963, and became available in the most large cities by 1965. It is a fully automated UHF/VHF network that allows a mobile node to connect to a landline phones, and was originally conceived to serve government officials and emergency services, but has since spread into general use, and is still in use in some places, where its advantages outweigh those of conventional cellular networks. Work on the system of automatic duplex mobile communication started in 1958 in Voronezh Research Institute of Communications (VNIIS, now concern Sozvezdie). It was established subscriber stations and base stations for communicating with them.
From the technical standpoint "Altai" was fairly ordinary UHF/VHF trunked radio, but it was equipped with the automatic switching circuits on both mobile and static nodes that allowed the mobile end of the link to generate and transmit dialing signals and to connect the static end to the PSTN. Few initial installations used 150 MHz frequency, but as the network grew the later iterations switched to 330 MHz. Base stations have had up to 22 independent trunks of 8 channels each, and were commonly mounted together with the TV transmitters, sometimes even sharing the HF circuitry. This allowed for good coverage, as there were generally only one base station per city.
The city of Altai (Mongolian: Алтай) is the capital of the Govi-Altai province (aimag) in western Mongolia. The capital is officially named Yesönbulag sum. It is not to be confused with the separate sum also named Altai in the south of the aimag. City population is 15,800 (2008 est.)
The Altai Airport (LTI / ZMAT) has one unpaved runway and is served by regular flights to Arvaikheer and Ulan Bator.
Altai has a subarctic climate (Köppen Dwc) with semi-arid influences. City experiences a long, dry, very cold winters and short, mild summers.

The childhood of the scientist has passed in Biryulka village in Siberia.
In 1938-1961, Okladnikov worked in the Leningrad Division of the Archeology Institute of the USSR Academy of Sciences.
Since 1961 Head of the Division of Human Research of the Economics Institute, Siberian Division of the USSR Academy of Sciences.
Since 1966 Director of the Institute of History, Philology and Philosophy, Siberian Division of the USSR Academy of Sciences.
Since 1962, Professor and Head, Department of History, of Novosibirsk State University.
His works include research on ancient history of Siberia, Far East, Mongolia, and Middle East. He identified numerous cultures of the Paleolithic, Neolithic, Bronze, and Iron Ages in Siberia and the Far East.
