A background requirement
With the popularization of campus network informatization, people are increasingly demanding the most convenient, fast, and mobile use of the network. At the same time, as the prices of laptop computers and wireless network card products gradually decrease, more and more people own According to surveys of wireless network client products, the average proportion of laptop computers owned by teachers and students in colleges and universities in China has exceeded 15%, and is increasing at an annual rate of 10%. Therefore, many colleges and universities began to think about how to make it impossible to extend many wired networks, as well as places such as large classrooms, auditoriums, conference rooms, library stadiums, etc., to also be able to access the campus network, and extend the network radius to the greatest extent. Let the network penetrate into every corner of the campus. For managers and builders of campus networks, this is a problem that needs urgent consideration and solution.
Two wireless LAN networking
One or more wireless switches are installed in the network center and connected to the core switch. Each wireless access point is connected to the access switch in the building nearby. A proprietary tunnel is established between the wireless access point and the wireless switch to achieve cross-wired Telecommunication.
Three wireless network applications
Four success stories
Mobile broadband
Mobile broadband is one of the basic applications of the wireless campus network. Its outstanding feature is that it allows users to access the campus LAN and the Internet anytime, anywhere, and obtain the information they need. The large bandwidth can ensure that multiple users can access network resources at the same time. Through such a mobile broadband to integrate the resources inside and outside the campus, the efficiency of resource utilization inside and outside the campus can be greatly improved, making up for the current situation where campus resources are generally tight.
Mobile security
On the wireless campus network, with Wi-Fi cameras, sensors and other related equipment, it is possible to build a wireless campus security network that can be inexpensive, on-demand, rapid response, and work intelligently. Campus safety has always been a very important aspect.
The wireless campus security network allows the school to increase or decrease the security surveillance cameras at any place at a low cost and little time, and even complete the security surveillance coverage of the entire campus. The security monitoring of school buildings, teaching buildings and other facilities can be quickly Respond to crimes, violations, fires, damage to buildings, etc.
Mobile communications
The wireless campus network can provide users on the campus with anytime and anywhere communication services, including: telephone (VoIP), video calls, SMS, e-mail, etc. By combining with appropriate billing and charging systems, the wireless campus network can reduce campus On the basis of communication expenses, it provides additional economic income for the campus. Users on campus do not need additional mobile terminals, and can use existing notebooks, PDAs, Wi-Fi phones and other devices.
Mobile campus management
Examination supervision, invigilators can check the examination room at anytime and anywhere.
Mobile school affairs, mobile management of student situation, logistics, etc.
Students can inquire about campus conditions, including meals, activities, etc.
Through the wireless campus network, school management personnel can access school management information anytime, anywhere, and conduct school management. For example, school administrators can access the campus network via PDA to view the status of students and teachers, or view logistics information to achieve dynamic and timely management of school affairs.
Mobile teaching
Through wireless, traditional teaching methods can be further improved. With the help of the wireless campus network, students can download the tutor's course anytime, anywhere, and replay the live tutor's course live; conduct online discussions with tutors and classmates; organize or participate in important academic video conferences, etc. Instructors can also use wireless networks to transmit data to students, arrange homework, organize exams, and even teach hundreds of students at the same time in their homes.
Mobile research
The wireless network can also make the scientific research on campus become anytime and anywhere. With such a network, scientific research can be carried out indoors and outdoors, while moving. For example: outdoor experiments need to call the data stored in the indoor equipment, or call the indoor equipment for data analysis, etc., can be carried out through the wireless network, and get the returned results. The freedom, convenience, and even safety of scientific research experiments and experiments are improved.
Mobile library
With a wireless network as a platform, a library that works continuously for 24 hours, can be updated and consulted anytime, anywhere, and meets the personal habits of users is completely possible. Teachers and students can refer to the books they need at any time and any place, to achieve convenient paper writing, homework completion, and interest reading.
Mobile entertainment
According to the management of the school, through the wireless campus network, teachers, students and other personnel on the campus can enjoy rich entertainment anytime, anywhere during the open time period. After combining a certain billing and charging system, under the guidance of the school, the wireless campus network can not only build a healthy, open and attractive entertainment atmosphere on the campus, but also realize economic income.
Mobile e-commerce
With the coverage of the wireless campus network, the school can effectively organize an e-commerce network anytime, anywhere. In this network, all expenses of teachers, students, etc. on campus can be settled through the system. For example: the cost of using the campus library, the cost of using the tutor's special courses, etc.
