The advantages using the architectural concept of the Network 2030 technology focus group using the recommendations ITU-T, FG NET-2030 (FG NET-2030) for building highly efficient multiservice wireless packet-switched cellular networks when providing a wide range multimedia services are analyzed. A review of the results of the Network 2030 study, carried out by the ITU-T FG NET-2030 focus group to study the capabilities and principles of building fixed communication networks for the period up to 2030 and beyond, is reviewed and analyzed. The efficiency indicators wireless cellular networks based on digital technologies have been studied and performance quality criteria have been selected to ensure acceptable quality of service QoS (QoS, Quality of Service) and Quality of Experience (QoE, Quality of Experience) of useful and service traffic. Based on the research, a new approach has been developed to create a method for calculating performance indicators of multi-service wireless cellular networks using end-to-end digital technologies. A general block diagram model of a digital wireless communication system under the influence of various noise sources is proposed to study the reliability of the transmission and reception discrete messages. Based on the proposed calculation method, complex indicators communication quality such as throughput were studied, taking into account the self-similarity property of heterogeneous traffic, the probabilistic-time characteristics of networks, and the energy consumption hardware and software of mobile wireless networks. As a result of the study, analytical expressions were obtained for estimating the parameters of the output modulated communication channel, predicting efficiency in the time and frequency domains, signal-to-noise ratio per bit, as well as energy consumption indicators in mobile wireless communication networks.
