The Design And Implementation Of A Campus Wireless Network

With the continuous development of China’s modern education, the constructionof digital campus was put on the agenda. In the school building, in terms of teaching,learning, or daily life, have become increasingly dependent on the campus network. Inthis one, the current need for more wireless networks is particularly urgent.In the process of the traditional campus network construction, generally are theerection of cable network is given priority to, because of limited network stability, inthe network design of computer room, laboratory and teachers, usually use cablenetwork to realize the information transmission. But with the continuousimprovement of living standards, smart phones, laptops and tablets and other mobileterminal equipment in People’s Daily life a lot of popularity, cable network has beenunable to meet the school faculty and students’ daily study and work. Rise andpopularization, and the current4g network show that the bandwidth of the network isno longer the limit of the network. Good network brought us the timing of the betteruse of the wireless network, the school also in urgent need of the construction of thewireless network, campus network to get fully utilized.Combined with the existing network technologies and the campus networkenvironment, analyze the deficiencies of the campus network, to propose a wirelesscampus network-based solutions to solve the blind spot for a wired network cabling;wireless channel detection is divided; wireless network security certification,management; user demand for wireless network and a series of problems. In thecampus wired network architecture, designed the wireless network topology structure;the user VLAN (Virtual Local Area Network) and the management VLAN to bedivided, the core switch configuration; according to the site survey, design andallocation of wireless access points methods and implementation steps; according tothe security requirements of the wireless network presents a line with the campusnetwork authentication solutions and implementation. In the course of the study, thereare two technical difficulties: different authentication systems, different manufacturers,wired and wireless network authentication network authentication seamlesscombination; Detection and divided channel. Through continuous testing, practice, theauthentication information is sent directly to the wired authentication serverauthenticate the finest means to solve the problem. This design results campuswireless network verification and analysis through several verification of signal strength, security services, as well as three roaming authentication technology, thewireless campus network construction as well as the basic realization of the designintent of the project make the campus wireless network to a trusted, controllable andavailable for operation.By enabling universities wireless network, it is possible for the school facultyand students work, study and life more convenient network environment in which theconstruction of the campus network can improve work, promote the development ofthe school.
