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
