infrastructure includes communication network infrastructure represented by 5G, Internet of Things, industrial Internet and satellite Internet, new technology infrastructure represented by artificial intelligence, cloud computing and blockchain, and computing infrastructure represented by data centers and intelligent computing centers.

Information infrastructure mainly refers to network equipment and facilities such as optical cable, microwave, satellite and mobile communication. It is not only the basic support for the informatization construction of the country and the army, but also an important part of the infrastructure to ensure social production and people's life. The construction of information infrastructure is characterized by large investment, long construction period, strong universality, strong public welfare, and military and civilian sharing.

Information infrastructure is not only the premise and foundation of informatization construction and application in various fields, but also the embodiment of informatization level. With the development and innovation of information and communication technology, information infrastructure is also developing in a new direction. In recent years, broadband network construction has been put in the first place, and high-speed broadband network has become the goal pursued by many countries and regions.
