PRIVATE LTE AND MISSION CRITICAL COMMUNICATIONS AND CONTROL SYSTEMS DOI: 10.22184/2070-8963.2022.102.2.30.38
The paper considers the use of LTE networks for professional purposes at mission critical infrastructure facilities. The feasibility of using private LTE networks for Mission Critical tasks is substantiated. Recommendations are made regarding the selection of bandwidths and a set of equipment for creating private LTE networks. It describes a complex solution for Mission Critical systems based on TRIALINK private LTE technology.
DEVELOPMENT OF FOCL FRAGMENT RESERVATION MODEL DOI: 10.22184/2070-8963.2022.102.2.50.56
A modeling algorithm for the additional routes optimal formation of network redundancy to provide a backup connection of nodes in case of damage to a portion of the FOCL section is proposed. The result of modeling is a set solutions formation for redundant FOCL in those areas where the reliability of communication network reliability does not meet the required values, as well as assessing the characteristics of the communication network fragment and its individual elements.

The paper describes the experience of implementation and installation of electronic price tags and peculiarities of their use in the shops of a Russian mobile operator. It describes the application, whose task is to implement additional functionality needed to optimize sales of subscriber equipment and accessories.
COMPENSATION OF DWDM SIGNAL SPECTRUM INEQUALITIES IN MULTI -SPAN LINES DOI: 10.22184/2070-8963.2022.102.2.58.62
Statistical characteristics of DWDM signal spectrum irregularity depending on the number of spans and statistical characteristics of irregularity of amplifiers used have been investigated. It was found that for a line of EDFA amplifiers with a gain up to 24 dB with 95% probability one amplifier insignificantly (by no more than 0.72 dB) increases spectrum irregularity. Amplifiers with higher gain (up to 35dB) increase the spectrum irregularity by about 0.95dB. Another cause of DWDM spectrum irregularity in multi-span links is the emergence of spectrum irregularity due to optical fiber attenuation spectrum irregularity and nonlinear Raman interaction of spectral channels. It is found that the nonlinear irregularity in the spectrum can be compensated by the coordinated slope of the gain spectrum of EDFA amplifiers.
INTERNET POTENTI AL OF SATELLITE SYSTEMS IN THE TRANSFORMATION ERA DOI: 10.22184/2070-8963.2022.102.2.64.66
