Goal. Architecture and radio access technologies of 5G networks set high requirements towards throughput, latency and reliability of the distributive transport networks. Regarding to this, the goal of this paper is to carry out the analysis of actual characteristics of microwave transmission planning and its application, which is essential for the wireless segment of the distributive transport network of 5G. Materials and methods. The requirements for automatization of the planning processes were defined for communication networks in general and for microwave transmission in particular. This requirements definition is based on analysis of 5G network architecture, its characteristics and development tendency. The automatization must embrace all of the planning phases, including the solutions of the calculation and information tasks. Moreover, the automatization must represent an instrument for the decision support in development, modernization and optimization of the telecommunication networks, including microwave transmission. This must be based on the modelling within a specialized software platform, which is able to cooperate with the external databases and management systems. Results. The longstanding research of the authors is embodied in the software complex for planning and optimization of telecommunication networks ONEPLAN, which has a module architecture. This allows to carry out the planning and optimization of microwave transmission, throughput capabilities and data traffic distribution within the transport networks, as well as to make the analysis for data traffic reliability. Conclusion. Planning process automatization by the software platform ONEPLAN maintains efficiently the forehanded, technically and economically reasonable decision making for the development, modernization and optimization of the telecommunication networks including the wireless segment of 5G transport networks based on microwave transmission.
