【正文】 WLAN 是當前移動互聯(lián)網的熱點技術。論文文理流暢，有較為詳實的實例支撐相關理論，是一篇合格的畢設論文。無線網絡具有的部署靈活性、終端可移動性、易擴展性等技術特點，使無線網絡比傳統(tǒng)有線網絡具有更佳的經濟效益，使無線網絡技術的應用進入高速發(fā)展階段。 關鍵詞： 無 線局域網；關鍵技術；協(xié)議體系 II Principle and design of WLAN Abstract With the rapid development of WLAN technology in recent years,wireless work is applied widly for its flexible disposition,terminal removability and expansibility. The paper first describes the historical background of the development of WLAN technology,followed by the introduction of WLAN position principle,working principle, key technology and protocol architecture,finally take the Zhongshan Uni office building WLAN construction project as an example,the paper proposed a WLAN solution that helps the implementation of wireless work project. Keywords: WLAN。Protocol architecture III 目 錄 1 緒論 .......................................................................................................................................... 1 選題背景 ........................................................................................................................... 1 論文研究的內容 ............................................................................................................... 1 2 無線局域網的概述 .................................................................................................................. 2 無線局域網的基本概念 ................................................................................................... 2 無線局域網的含義 .................................................................................................... 2 無線局域網的特點 .................................................................................................... 2 無線局域網的優(yōu)點 ................................................................................................ 2 無線局域網的不足 ................................................................................................ 3 無線局域網的組成原理 ................................................................................................... 3 無線局域網的組成結構 ............................................................................................ 3 無線局域網的拓撲結構 ............................................................................................ 3 無線局域網的工作原理 ................................................................................................... 6 無線局域網的關鍵技術 ................................................................................................... 6 無線局域網的協(xié)議體系 ................................................................................................... 7 無線網絡邏輯結構 .................................................................................................... 7 IEEE ......................................................................... 7 3 無線局域網設備 .................................................................................................................... 10 無線網卡 ......................................................................................................................... 10 常見室內 AP ................................................................................................................... 11 室外無線接入點 /無線網橋 ............................................................................................ 13 常見無線網橋 ................................................................................................................. 14 常見無線路由器 ............................................................................................................. 15 無線控制器 AC .............................................................................................................. 15 4 中山聯(lián)通辦公樓無線局域網設計 ........................................................................................ 16 設計思路 ......................................................................................................................... 16 組網方式 .................................................................................................................. 16 Fit AP+AC 的管理方式 ........................................................................................... 17 設計目標 ......................................................................................................................... 17 技術指標 ......................................................................................................................... 18 技術指標 ........................................................
