The paper discusses modern approaches to building convergent communication networks that combine reliability of traditional professional mobile radio communication systems with the broadband capabilities of LTE/5G technologies. Using solutions from Hytera as an example, the architectural features, end-to-end integration mechanisms, and practical aspects of implementing such systems in industrial enterprises are analyzed. Special attention is paid to the technological aspects of integrating heterogeneous networks, ensuring uninterrupted communication, and creating a unified communication space for critical services.
