Best Practices of Zhengzhou University Wireless Campus
In the Internet era, web-based applications are everywhere in this world. It's hard to imagine what the world would look like without the Internet ... And today, with the advancement of wireless technology and the rapid popularization of smart terminals, the convenience of wireless networks has made them more widely used. Here we will introduce the best practices of wireless campus based on H3C product technology of Zhengzhou University.
Speaking of Zheng Da, I believe many people are familiar with it, and I will no longer introduce the school profile and go directly to the topic. The wireless campus project of Zhengzhou University started in the first half of 2011 and started trial operation by the end of May this year. It has basically achieved its expected goals: teachers and students use the wireless network with real names; teachers use campus card numbers, all of which can be used; graduate students, undergraduates, and junior college students 1. International students use student IDs, only campus network users have the right to use them; seamlessly connect with the school's unified identity verification system; record all usage logs, and locate users by IP address.

Preliminary work of the project
The wireless campus project of Zhengzhou University started its investigation in 2010. After repeated comparisons, the idea of ​​the campus wireless layout was determined, that is, the fixed information point is mainly used, and the wireless is supplemented for construction.

Professor Gao Jinfeng, director of the Network Management Center of Zhengzhou University, said, "In fact, the wireless network construction of Zhengzhou University is relatively late. At first, it was only a small-scale trial, technology tracking and mastering. At that time, we thought it was not very good. When we were mature, we did not push wireless technology on a large scale, but focused on fixed information points. With the increase of mobile devices and the maturity of wireless technology in recent years, we began to consider wireless technology.
During the construction of the project, network security and management issues were also fully taken into account. Zhang Hongpo, director of the Operations Department of the Network Management Center of Zhengzhou University, said, "In fixed information points, the IP is used by the department as the unit, and the IP is determined by the department. Who can use it, the home area and the student living area are also accurately located to people by binding IP and account numbers, and then managed by unified identity authentication. "
Wireless campus best practices
Zheng Da's network deployment uses a plug-in AC controller, two SSIDs are enabled, and the AP address and user address are all assigned by DHCP. At the same time, the unified identity authentication platform is used for user identity authentication. Zhang Hongpo said that at present, the application of wireless networks is people-oriented, and the account permissions assigned by people with different roles are also different. The construction of the wireless network allows faculty, staff and students to understand their relevant information whenever and wherever needed.

Professor Gao Jinfeng said, "From an informatization perspective, no matter how advanced the technology is, the key is to satisfy users. That is to say, the development of technology and the real user experience are at a distance. Users can experience earth-shaking changes. In the construction of the wireless campus, we have also fully considered this. Zhengzhou University is a local school, so the funds are limited, and we have to ensure that every penny is spent on the blade. "
Zheng Zhisong, director of H3C's product department, also said, "The challenges we face in the future wireless must be how to better improve the customer experience, how to better adapt to the development of explosive growth of smart terminals, who can solve this problem, who 'S wireless will definitely take the lead in the global market. "

When introducing the successful case of Zheng Da ’s wireless campus, Professor Gao Jinfeng also talked about some of the difficulties currently facing: there is no problem for desktops and notebooks, but for mobile devices, compatibility is a big problem . This is also a bottleneck restricting the in-depth application of wireless networks.
In the process of wireless campus construction, operators are also competing for this market. In response to this phenomenon, Professor Gao Jinfeng put forward his own view: "While we are building our own wireless network, we also allow operators to build their own wireless network on campus, but the management of the export of the network should be placed on the school side for unified Identity authentication. This is convenient for unified management, and can quickly locate people if there is a problem. This is a prerequisite for the operator's wireless network to enter the campus. "
In response to the problem of integrated network wired and wireless management of Zhengzhou University, Director Zhang Zijiao of the Network Management Center said that the network construction of Zhengzhou University is supplemented by wired and wireless, but in fact it is one. There is no such two problems. . When doing wireless network planning from the beginning, it was considered to reduce the cost of accessing the cable. The other is the integration of wired and wireless.
Project experience sharing
The wireless campus project of Zhengzhou University lasted one year and basically achieved the initial target. The wireless campus project can be successfully implemented, and Professor Gao Jinfeng also said, "I think that we did not do wireless in the past few years, and we did not make large-scale investment. In fact, the decision is correct. There have been successful cases in the past few years. Failure cases. The implementation of wireless projects must take into account user experience, user experience, and user utilization. If you do not consider the characteristics and needs of users and adopt a one-size-fits-all approach, you will definitely encounter many setbacks and even projects Will die. "
Summing up the successful experience of the wireless campus of Zhengzhou University, we can see that the preliminary investigation of the project accurately grasps the characteristics and needs of users, chooses the solution that suits them, costs control, unified identity management, etc. Constitutes the success of today's project. At the same time, effective communication between manufacturers, integrators, and schools is also very important throughout the project.
Generally used in restaurants, cafes, hotels and other public eating places, can be used as advertising accessories to enhance the image.
The colorful plastic coasters are added to the company and the corporate LOGO is more prominent, closer to people's lives, and the strong friction prevents the glass and porcelain cups from slipping.
It also protects the desktop from burns.
