通信 无线覆盖毕业论文.doc

 摘要 随着社会经济迅速发展，互联网与无线通信技术相融合。高速率、高性能和兼容性已成为普遍要求，对随时随地的进行通信和信息服务的要求变得迫切。个人数据通信的发展，功能强大的便携式数据终端以及多媒体终端得到了广泛应用。现有的有线网络某种程度上已经不能满足人们的需求，因此，无线化、智能化的移动通信和快捷的无线接入，无线互联等众多适应当前人们需求的网络应运而生。 校园网是教师和学生获取资源和信息的主要途径之一，它在校园教育中的作用与地位日益显著。教师和学生对校园网的依赖性相当之高，“随时随地获取信息”已成为广大师生们的新需求。但是，传统的有线校园网存在着诸多“网络盲点”，比如在图书馆、大型会议室、体育馆等许多不宜网络布线的场馆设施如何联网？在教室、实验室等场合如何突破网络节点限制、实现多人同时上网的问题？无线局域网络可以成功弥补有线校园网的不足，与校园有线网络相得益彰，共同构建一个无处不在的校园网络。 本论文对校园无线网络的分析为更好地实际应用相对稳定的网络通讯服务而设计。 关键词： 校园网 无线局域网 AP接入  Abstract With the?rapid development of social economy,?the combination of the Internet and?wireless communication technology.?High speed,?high?performance and compatibility?has become the common?requirements,?for?whenever and wherever possible?the communication and information service?requirements are becomingurgent.?The development of personal?data communication,?powerful portable data terminals and?multimedia terminal?has been widely applied.?To some extentthe existing?wired networks?can not meet?peoples needs,?therefore,?wireless,intelligent?mobile communication?and fast?wireless access,?wireless Internet,?to adapt to the?demand?of network?emerge as the times require.
