The article considers a new method for calculating the attenuation of cellular signals during their propagation in the forested areas frequently occurring in the Astrakhan region (linden) and the regions where the above trees predominate. There are also discussed the empirical models of a radio wave propagation in the forested areas, such as a Weisberger model and a COST-235 model. There have been built the curves of signal losses on the routes derived by the new method. There was conducted the experiment determining the effectiveness of the developed method. The obtained method has been found efficient for improving the accuracy of the preliminary design of radio communication systems

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.
