某地住宅小区室内无线网络覆盖系统设计.doc

毕业设计 题 目： 住宅小区无线网络室内覆盖系统设计 摘要 无线局域网络（Wireless Local Area Network；WLAN）是相当便利的数据传输系统，它用射频技术（Radio Frequency；RF）的技术，取代旧式的双绞铜线（Coaxia）所构成的局域网络。应用无线通信技术将计算机设备互联起来，客户可通过笔记本电脑，PDA等终端以WLAN随时随地接入互联网和企业网，获取信息、娱乐或进行办公。支持多媒体功能，上传下载，随时欣赏网上影片或音乐。提供急速而稳定的无线连接。 本文首先对WLAN技术在国内外的现状以及发展趋势进行了概述并且对住宅小区无线网络室内覆盖的需求进行了分析；然后本文对目前的无线网络技术进行了详细的分析，对无线网络的优点与不足、无线局域网的分类、无线局域网的组成、无线局域网的拓扑结构、无线局域网协议体系结构进行了表述；接着本文进行了住宅小区无线网络室内覆盖系统设计，在设计中明确了住宅小区无线网络室内覆盖设计原则，综合考虑多种因素选择了合适的协议标准，并且对组网所需的各，种设备进行了选择，明确了现场勘测原则，对住宅小区无线网络室内覆盖的设计进行了分析并得到了设计方案。最后本文对住宅小区无线网络室内覆盖系统的安全与防护进行了研究，并得到集中常见的攻击方式以及防御措施。 关键词：WLAN ，设计 ，室内. Abstract Wireless Local Area network （Wireless Local Area Wireless local-area network,WLAN）is quite grow independently;the gata transmission system is convenient,have been using RF(RF);the technology,replace old-fashioned double ground wire（getting Coaxial）that form the Local Area network,making.Wireless communciation technology willbe applied computer equipment,customers can through interconnected up laptop computer,PDA,etc in WLAN anytime terminal access tothe internet and enterprise nets obtaining information,entertainment or office.Support multimedia function uploads and downloads.always appreciate,music videos or online.Provide speed and stable wireless connection. Based on the present situation of WLAN technology at home and abroad and its development trend are summarized and the residential area wireless network indoor coverage needs of analysis; Then this paper discusses the present wireless network technology are analyzed in detail, and to the wireless network advantages and shortcomings, the wireless local area networks classification, the wireless local area networks composition, wireless LAN topology structure, the wireless local area network protocol system structure of expression; Then this paper the residential area wireless network indoor coverage system design, the design was made clear in the residential area wireless network indoor coverage design princi
