One, 现状及问题 Status and Problems of Smart Campus in Primary and Middle Schools
two, Smart campus needs analysis
Wireless Internet security: Schools hope that the campus network has comprehensive security guarantees to prevent serious teaching accidents caused by leakage or loss of teaching materials. The importance of network security is also clearly pointed out in the main points of education informatization and network security issued by the Ministry of Education in 2018.
Wireless network stability: The wireless network deployed on campus must consider the user experience from multiple aspects. It must not only provide stable and fast Internet access services in the process of surfing the Internet, and ensure that students and teachers do not get disconnected or stuck when using the wireless network to access the Internet. To meet the daily Internet applications.
Mobile office requirements: access to internal business systems for office work, while ensuring user access and data security.
E-schoolbag construction: Currently, e-schoolbags are being piloted in various parts of the country. For the field of elementary and secondary education, e-schoolbags have been improved several times and are now becoming mature. The mobile nature of the terminal PAD has put an urgent need on the wireless construction of general education campuses.
Network management needs: In the process of promoting informatization construction, schools urgently need to simplify the network structure to minimize construction costs, operation and maintenance costs.
