WIFI coverage solution of medical school in Wuhan City
Background analysis:
With the rapid development of information technology, the tentacle of information construction has also penetrated into the education industry. At the same time, with the development of wireless local area network technology, the pace of deployment of wireless campus network in China is also faster and faster. With the advantages of flexible layout, high bandwidth and wireless access, WLAN can break through the limitations of wired network nodes and realize the simultaneous access of multiple people. It greatly increases the information points of campus network, facilitates the access of information to teachers and students in schools, and further improves the informatization level of schools.
Demand analysis:
The demand analysis of campus wireless coverage is as follows:
1. Campus wireless network covers outdoor areas such as student dormitories, teaching buildings, libraries, gymnasiums and school roads.
2. Because of the need of modern teaching interaction, teaching buildings often have a large number of terminal access at the same time, and wireless AP needs to meet the needs of high bandwidth.
3. Students'dormitories and libraries are mostly used by teachers and students to access information on the Internet. They need to meet the needs of full coverage of all regions and certain access volume.
4. The gymnasium is generally relatively spacious. As the venue for school gatherings, lectures and other activities, the staffs are the most intensive. Wireless AP needs to meet larger access volume and support load balancing.
5. The network construction of the road part is mainly covered, supplemented by capacity, and AP is installed outdoors, so the need of waterproofing and lightning protection should be considered.
6. Wireless AP needs to support transmitting multiple SSIDs, and different SSIDs have different permissions, that is, SSID must support binding VLAN;
7. The general wireless authentication mode of campus wireless network is portal authentication. Teachers and students use their own accounts and passwords to log in and use them.
8. Campus wireless coverage scheme uses more AP, which supports unified management and configuration, and real-time monitoring of the working status of each AP. It is easy to operate and maintain.

Installation and deployment
1. Teaching building part: The main coverage part is the inside of the classroom. According to the size of the classroom and the number of users, we can plan the location reasonably. Generally speaking, the coverage radius of ceiling-suction AP is 10-12 meters, as shown in the following figure:
AP Layout of Teaching Building
2. Student dormitory: You can choose panel AP scheme. AP is installed inside the dormitory. Each AP covers 1-3 rooms. You can also choose ceiling AP scheme. AP is installed in the corridor outside the dormitory, covering 4-6 sides.
Room. As shown in the following figure:
Panel AP Layout
Top-suction AP layout
3. In the library, the top-suction AP can be used to plan the location reasonably according to the actual situation. Generally speaking, the coverage radius of top-suction AP is 10-12 meters, as shown in the following figure:
4. Gymnasium: Relatively empty, fewer barriers, ceiling AP covering 20-30 meters in the open environment, according to the size of the use of discretion, the number of points evenly distributed, as shown in the following figure:
5. Outdoor of School Road and so on: use HUXCOM outdoor high-power AP coverage, in general, the coverage radius can reach 100-300 meters, outdoor installation, waterproof and lightning protection.
Programme features:
The scheme uses HUXCOM commercial wireless products to achieve coverage, and uses wireless controller AC and FIT AP to deploy. It has the following characteristics:
High Availability: AP uses professional antenna, with large capacity and linear adjustable transmitting power. According to the actual environment, the transmitting power of AP can be adjusted reasonably to meet the coverage requirements of different regions.
High reliability: FIT AP scheme is adopted to support load balancing. AC can dynamically adjust the uniform distribution of users among different AP to prevent overload of individual AP.
High scalability: MAC authentication, Portal authentication and other user access authentication methods, which can be combined with external portal server and authentication server to implement web authentication, SMS authentication, authentication and other authentication methods.
Flexible use: Support SSID binding VLAN, flexible and convenient control of different SSID network privileges.
Easy to deploy: AP supports 802.3af/at standard PoE network power supply. It can be installed either by suction or wall mounting. It is flexible to use according to local conditions. Outdoor AP adopts professional outdoor shell design to adapt to various harsh environments.
Easy to manage: FTT AP is managed by wireless controller AC. It can automatically discover and manage AP. It can view AP running status in real time and facilitate network management and maintenance.
