Background analysis

On January 25, 2017, the General Office of the Ministry of Education issued a notice on the "Key Points of Education Informationization Work in 2017". The main content is to basically realize the full coverage of the school's Internet coverage and the full coverage of the network teaching environment. The access bandwidth is above 10M. The proportion of schools reached 70%, the proportion of multimedia classrooms in ordinary classrooms reached 80%, and the proportion of schools equipped with multimedia teaching equipment in ordinary classrooms reached 60%, promoting the construction of digital campuses and smart campuses. Nowadays, the full coverage of school Internet has become a trend of school development.

Demand analysis

(1) Network speed and network stability issues.

At present, the wireless campus network needs to ensure that each user has a fast Internet access and does not drop the line, while ensuring that teachers and students are connected to the Internet and access the Internet safely.

(2) The signal has no dead angle and does not cause interference.

In the design process, it is necessary to consider the differences in different teaching environments to ensure that the wireless network is unblocked.

(3) The wireless campus network should support various types of terminals.

With the increase in the number of wireless devices with mobile functions, it is necessary to fully consider the smooth access of mobile terminals such as notebooks, various mobile phones, and iPads in the design process of wireless campus networks.

(4) There are many types of equipment, which is difficult to manage and maintain.

For the campus wireless network administrator, the convenience of equipment maintenance management should be fully considered in the process of designing the wireless campus network. For example, unified online management of devices.

(5) Network scale (2000-4000 people).
