The University Campus Wireless LAN Design Based On 802.11 Protocol

With the development of wireless technology, more and more industry began to use wireless communication technology, the majority of users agree with the reliability of the wireless technology, and begin to apply it in the more complicated and more massive network layout. With the update of the progress of the society and technology, the wireless network in the various kinds of usage scenarios, there are a home user are central enterprises or cluster users, it can serve as a separate network access mode for the user to provide Internet services, can also be used to supplement the wired network, complete the complicated network environment of network access, in every industry network structure plays an important role.Now most universities/schools have popularized the information management system, the degree of campus informationization construction to improve the quality of teaching, to improve office efficiency is very intuitive. Changes in the education mode and promoting the construction of campus informatization from pure teaching management to the entire campus promotion, at the same time, in the network technology developed in today’s society, a good cultural atmosphere for the students’ physical and mental health development plays a very important role.In this paper, according to the campus network construction project procedures, from the business orientation, network demand analysis, network topology design, validation of user access, business risk prevention and post maintenance of campus network construction were more comprehensive research, and puts forward some improvement measures. The second chapter is to introduce the network architecture and protocol of WLAN, the "fat" "thin" and the two kinds of AP network to make the comparison. The third chapter is the design of the campus network. The paper analyzes the business requirements of campus network, analyzes the two kinds of campus network. The fourth chapter introduces the security risks and preventive measures. The fifth chapter introduces the security risks and preventive measures.
