淺析校園無線局域網(wǎng)的構(gòu)建


【摘要】 校園網(wǎng)已經(jīng)成為校園生活的重要組成部分，成為教師和學生獲取資源和信息的主要途徑之一。目前多數(shù)校園網(wǎng)均是建立在有線網(wǎng)絡基礎之上，隨著信息技術(shù)的飛速發(fā)展，“隨時隨地獲取信息”已成為廣大師生們的新需求。但是，傳統(tǒng)的有線校園網(wǎng)存在著諸多“網(wǎng)絡盲點”，比如在圖書館、大型會議室、體育館等許多不宜網(wǎng)絡布線的場所如何聯(lián)網(wǎng)？在校園如何突破網(wǎng)絡節(jié)點限制、實現(xiàn)多人同時上網(wǎng)等等。隨著無線網(wǎng)絡技術(shù)的飛速發(fā)展，這些問題便迎刃而解；從應用需求方面考慮，無線網(wǎng)絡很適合學校的這些不易于網(wǎng)絡布線的場所。本研究通過實際調(diào)查和查閱文獻資料等方法，介紹無線局域網(wǎng)的概念、原理、特點及無線網(wǎng)在校園中的應用現(xiàn)狀，在此基礎上，結(jié)合校園實際需要，建構(gòu)一個可行的無線網(wǎng)物理和邏輯上的基本設計方案。

The Brief Analysis of the Construction of Campus WLAN


【 abstract 】 Campus network has become an important part of campus life, and become one important way which teachers and students can obtain resources and information from it. Currently most campus network are based on cable network, with the rapid development of information technology, "at any time and place for information" has become the new demands for teachers and students. However, the traditional cable campus network exists many "network blind spots", such as in the library, large conference room, gymnasium and many other place where the network is not easy to cable,how to place the internet? For school to break down the network node restrictions, realize that many people can be on the internet together? With the rapid development of wireless technology, this problem can be solved; think of the application requirements, wireless network applications are suitable for some places of school where the network are not easy to cable.This study is based on investigation and review of the literature material,etc, first introduces the concept of the wlan(wireless local area network), the principle,characteristics and the present application situation of the wireless network on the campus, and on this basis, combining with the actual needs of campus for wlan, build a feasible physical and logical design scheme of the campus wlan.
【 key words 】 Campus network; Wlan(wireless local area network); Application; Building
