5G Technology, while being operationalized before the implementation of the specific assigned standard IMT-2020, is considered to be a game changer in the communications field with an impact on the industry and society equivalent with the Internet breakthrough. 5G has the capacity to enhance civil and military communications systems, the intelligence field and critical communications infrastructures. Despite all the benefits brought by the new technology, 5G has become the source of the first strategic dispute between US and China in the technological field (non-literary known as the first „cold war in technology field”). This article is presenting an analytic perspective of the risks associated with the 5G with regard to national security. [ABSTRACT FROM AUTHOR]

This paper presents the robustness analysis of the interdependencies between urban critical infrastructures (CI) against cascade failures. An analytical approach based on the dynamic percolation theory was introduced to investigate the multilayer interactional CI networks and to predict the urban calamity spreading as illustrate with example of China. The synergetic effect of the functional and geographical interdependencies between the networks on cascade failures of CI was studied by comparing four relevance patterns: no interdependency, the functional interdependency, the geographical interdependency, and the functional with geographical interdependency, where three different attack strategies were simultaneously considered. The results indicate that the geographical interdependency has a remarkable influence on the robustness of networks compared with functional interdependency. Moreover, excavating the scope and extent of the impact of these interdependencies, one can also find that the power network basically governs the cascade failures of global systems in contrast with water or gas network.
