Frequency-territorial planning of trunking communication systems

Abstract

The article considers the design of a trunking communication system using the proposed method of automatic placement of base stations and the developed software. The aim of the work is to reduce the complexity of designing trunking communication systems. In the automatic placement method, special attention is paid to calculating the required number of channels for organizing communication between a given number of subscribers. The scientific novelty of the presented solution lies in the fact that in the method of automatic placement of base stations, the coordinates of their installation locations are determined using the proposed greedy algorithm, in which the calculation of the service areas of base stations is carried out on the basis of a modified Hut model. Then, for the obtained coordinates of the base station installation sites, an updated calculation of the service areas is carried out, taking into account additional diffraction losses, tropospheric scattering and losses in the atmospheric waveguide. After that, the guaranteed service area is determined. The results of the design of the trunking communication system in the developed software are presented, graphs of the dependence of the calculation time of the greedy algorithm on the area of the territory that needs to be covered by the connection are given.
