The authors of the article consider solutions needed to organize mobile cellular communication systems in remote areas. Modern mobile stations do not have the capability to overcome marshy areas, steppe, heavily rugged reliefs of the desert, water barriers and forests. Moreover, the coverage area from one base station is not highly localized (radio coverage area is not significant). Furthermore, modern mobile communication facilities have poor autonomy. The article proposes measures for an operational organization of cellular communications in large remote areas with a coverage radius of a medium-sized city. Article also considers the issues posed by a temporary organization of communication service in large sections near important locations (pipelines, riverbeds, transport and railway lines). The need for such an operational usage of mobile communication systems is most associated with geological exploration and scientific research in large remote areas and large areas with a damaged communication system due to natural emergencies or military operations.

The article substantiates the assertion that for radio communication design areas in the territory close to the hydrospheric objects (rivers, lakes, sea areas) it is necessary to use calculation methods taking into account the difference in the level of signal attenuation due to seasonality. This is especially true for the Astrakhan region characterized by hot summers (to which it is advisable to add the last month of spring - May - and the first month of autumn - September, also characterized by high air temperatures). Seasonal features of radio wave propagation are determined by the continuous superrefraction above the water part of the radio line, which is formed due to the temperature inversion during the whole period of hot weather in the Astrakhan region. This is a fairly long period of time (at least 5 months a year) that must be taken into account in design systems to obtain an accurate picture of the signal level distribution in the ultra-high frequency range for such systems as television and radio broadcasting systems, cellular communication systems. Upon the results of the research and field tests it has been inferred that the effect of ultra-long-range propagation of radio waves in a tropospheric waveguide does not depend on the frequency range of the radiating system. A new method for calculating the attenuation of radio signals over the water surface in the near-water tropospheric waveguide has been developed.

Purpose of the work is to propose provisions for the aggregation of parameters of a climatic and anthropogenic nature. Regulations are necessary to determine the rating of forest areas in terms of fire hazard level. As a result of the study, theoretical provisions for the aggregation of variables have been proposed. Variables are described on different metric scales and affect the final result in different ways. The provisions are based on the methods of the theory of fuzzy sets and fuzzy inference. The computational complex for determining the rating of the forest areas is implemented in the form of a hierarchical system of fuzzy inference. It is based on the Takagi-Sugeno algorithm. Simulation of the complex operation was carried out. As a result, it was concluded that the generated output pattern has a stepped nature. This makes it possible to classify the analyzed elements into state groups. This allows you to solve the problems of planning work on the implementation of preventive and/or preparatory measures to eliminate or prevent forest fires. The prospect of further research is the formation of decision support systems in the control processes organization of forest areas.
