On September 29, the XIV International Forum-Exhibition "Professional Mobile Radio Communication, Satellite Communication and Navigation", organized by infor-media Russia, took place in Moscow. Despite the challenging times for the conference business, more than 100 delegates from among the end users of professional communications, executives and leading specialists of companies providing industry solutions and technologies gathered offline to discuss the current state and development trends of the critical telecommunications industry.
NOTES ABOUT (INJECTORS) POWER OVER ETHERNET. PART 1 DOI: 10.22184/2070-8963.2020.92.7-8.68.73
The article is devoted to the issues of Power over Ethernet technology – the development of injectors, their compatibility with other equipment, and operational problems. Over the years, periodically there were problems that the author had to solve and questions that required an answer. Some of them are briefly described in these notes, in the title of which the word "injectors" is placed in parentheses, since everything described applies, to a large extent, to PoE technology in general.
EVOLUTION OF MODELS OF SCS COPPER LINKS AND CHANNELS DOI: 10.22184/2070-8963.2020.92.7-8.26.31
The main models of complex SCS objects are considered: permanent links and channels based on an electrically conductive element base used in the process for constructing classic 4-pair and promising single-pair cable lines. The objective necessity of expanding the range of such models is shown as the list of tasks solved by the building information system expands. Their continuity is demonstrated. The objectivity of the necessity of certain reserves in terms of the parameters of cable lines is substantiated.
WIDELY APPLICATION OF ALUMINUM CONDUCTORS IN COAXIAL TV-CABLES AND TWISTED PAIR CABLES IMPORTED FROM SOUTHEAST ASIA DOI: 10.22184/2070-8963.2020.92.7-8.32.37
The purpose of this article is to warn buyers of telecommunication cables. The use of cables with conductors and/or aluminum braids has serious technical limitations. They can only serve simple tasks at a primitive everyday level. CCA conductors do not allow any form of remote PoE power supply.
FOCL CONTROL PROVIDED BY THE BRILLOUIN REFLECTOMETRY METHOD: PROBLEMS AND POSSIBLE SOLUTIONS DOI: 10.22184/2070-8963.2020.92.7-8.38.44
The urgency of the problem of monitoring the state of fiber optic lines in conditions of temperature-deformation effects is considered. The influence of the optical sensor calibration error and instrumental error on the accuracy of temperature and deformation determination is simulated. A new method of post-processing the reflected Brillouin optical spectrum which makes it possible to obtain more accurate values of temperature or strain in the optics is demonstrated. The results of simulation and experiment showed the reliability of the proposed solutions for simultaneous control of temperature and deformation of an fiber optic cable.
INTELLIGENT TRANSPORT SYSTEMS ARE IN THE CENTER OF ATTENTION DOI: 10.22184/2070-8963.2020.92.7-8.64.67
Transport is one of those industries where digitalization has already been taken seriously both in the center and in the regions. One could be convinced of this at the forum "Intelligent Transport Systems of Russia: Digital Era of Transport" organized by the "Digital Era of Transport" Association for the fifth time, which took place in the capital on October 7-8. The forum has become the main platform in the country that brings together customers and solution providers at the intersection of transport, telecommunications and IT. The key theme of the anniversary event was announced by the organizers: "What? Where? When?" in the digital transformation of the transport complex".
EXPERIMENTAL STUDY A NOISE-IMMUNE CODEC FOR A TRANSMISSION LINE COMMUNICATION SYSTEM DOI: 10.22184/2070-8963.2020.92.7-8.74.75
Improving the modern comfortable urban environment is impossible without the Internet of Things.
DEVELOPMENT OF SUBSCRIBER ACCESS NETWORKS DOI: 10.22184/2070-8963.2020.92.7-8.76
SATELLITES, ORBITS AND FREQUENCIES IN REALITY OF 2020 DOI: 10.22184/2070-8963.2020.92.7-8.48.52
Trends in the development of digital technologies and issues of transformation of satellite communications under the influence of COVID-19 pandemic, the future of the industry in modern realities, development of 5G-based services, problems broadcasting and media industries – themes of the XXV International conference of operators and users of the satellite communication networks of the Russian Federation SАTCOMRUS 2020, held this year in online mode.
INTERNET OF THINGS ON SATELLITE TECHNOLOGIES DOI: 10.22184/2070-8963.2020.92.7-8.46.47
Participants of the online round table "The place of satellite technologies in the market of the Internet of Things", organized as part of the "Russian Week of High Technologies – 2020" of the Federal State Unitary Enterprise "Space Communications" on the initiative of Rossvyaz, discussed the possibilities of using and prospects for the development of satellite technologies in the IoT ecosystem.
V.M.NAGORSKY: THE FATE OF A COMMUNICATIONS ENGINEER AND INVENTOR DOI: 10.22184/2070-8963.2020.92.7-8.78.83
V.M.Nagorsky (1870 – after 1917) is known to a narrow circle of researchers in the history of communications for his unusual inventions at the intersection of telephony and telegraphy. At the beginning of the 20th century, the brilliant engineer and communications organizer V.Nagorskiy made a significant contribution to telephoning the country, in the rebellious 1905 he established communications in Siberia, made an impressive administrative career and deserves to be remembered by descendants and, especially, colleagues.
