ARMY-2020 THROUGH THE EYES OF A COMMUNICATION SPECIALIST DOI: 10.22184/2070-8963.2020.91.6.10.18
The Army International Military-Technical Forum, organized by the Russian Ministry of Defense, has celebrated its fifth anniversary this year. The VI Forum "Army-2020" was held 14 months after the previous one – on August 23-30, its central events were held at three traditional sites in the Moscow region: the Patriot-Expo convention and exhibition center, at the Alabino training ground (land and water demonstration clusters) and the Kubinka airfield. In addition, part of the demonstration shows took place at the Ashuluk training ground in the Astrakhan region. The main distinguishing feature of the 2020 Forum was its joint holding with the International Army Games.

BWA INCREASES PERFORMANCE DOI: 10.22184/2070-8963.2020.91.6.36.37
Wireless broadband access (BWA) continues to compete successfully with other last mile technologies. The designers of this class of equipment are constantly improving its characteristics. An interesting example of new developments that can already compete with access networks based on copper and even fiber optic cables are PtMP (Point-to-Multipoint) solutions introduced to the market this year by RADWIN.

STUDY OF POTENTIAL ACCURACY CHARACTERISTICS OF SMALL-BASE SYSTEMS CONSTRUCTED BY TRIANGULATION METHOD FOR DETERMINING THE COORDINATES OF RADIO RADIATION SOURCES DOI: 10.22184/2070-8963.2020.91.6.38.43
Determination of the coordinates of radio emission sources is an important task in many areas of mobile communications, radio navigation and radio monitoring technology and comes down to determining the angular direction to the source and the distance to the radio emission source. If the first problem is solved using sufficiently accurate methods, then the second (determining the range) causes difficulties. Various triangulation methods are the main method for determining the distance to a radio source. When constructing a triangulation measuring system, the concept of a base is introduced, which is characterized as the distance between measuring points. High accuracy in measuring the distance to the radio emission source can be ensured only by creating a measuring system with a large base, reaching in some cases several hundred kilometers. The article examines the possibility of constructing low-base systems for determining the coordinates of radio emission sources based on triangulation methods.

LPWAN TECHNOLOGIES AND THE POSSIBILITY OF THEIR ADAPTATION FOR SATELLITE IoT NETWORKS DOI: 10.22184/2070-8963.2020.91.6.44.53
The technical parameters of the most famous LPWAN technologies are presented. It is noted that the vast majority of LPWAN technologies are proprietary. LoRa technology occupies a special place, which is practically the only open technology. The results of the analysis of the adaptability of LPWAN technologies for use in satellite IoT networks, focused on direct access with terminal sensors, show that LoRa technology is the most promising technology. The article presents graphical data of the relationship between the signal-to-noise ratio and the probability of error per bit, which provide an objective assessment of the budget of subscriber radio links of satellite channels implemented on the basis of LoRa technology.

DEVELOPMENT OF THINKING PROCESSES OF STUDENTS WITH TAKING INTO ACCOUNT THE DOMINANT FORMS OF PERCEPTION DOI: 10.22184/2070-8963.2020.91.6.64.71
The article considers the problem of choosing rational forms and methods of conducting classes, taking into account the dominant forms of representative systems of students and their status potentials in the group. The methodology is based on the method of analyzing hierarchies under the assumption of fuzzy expression and diagnostics of representative systems of students. A number of basic didactic rules of the head’s actions on methodological improvement of classes are also considered.

M.F.FREIDENBERG ABOUT INVENTION IN RUSSIA AND ABROAD DOI: 10.22184/2070-8963.2020.91.6.72.79
M.F.Freidenberg left a noticeable mark on the genesis of automatic telephone communication. The documentary fund of the Central Museum of Communications contains materials reflecting various aspects of the inventor’s multifaceted activity. Of great interest is M.Freidenberg’s manuscript "Memoirs of an Inventor", written in 1913. The problems with Russian invention, which he outlined more than a hundred years ago, are in many ways relevant today.
