无线局域网的分析与设计
摘要
随着大学校园网络数据传输需要的逐渐增加,特别是应用数据、话音、视像多媒体的传输量的增加,校园网建设正向数字化、智能化方向发展。而校园无线局域网作为校园网的重要组成部分,因此在校园网中建设无线局域网作为有线校园局域网的重要补充显得尤为重要。
无线局域网是相当便利的数据传输系统,它利用射频技术,取代旧式的双绞铜线所构成的局域网络,使得用户能够利用其简单的存取架构,信息随身化、随时随地连接网络世界。 无线局域网弥补有线局域网络之不足,以达到网络延伸之目的。高校校园网的网络建设与网络技术发展几乎是同步进行的。高校不仅承担着教书育人的工作,更承担着部分台的发展趋势, 为了充分满足高校骨干网对高速、智能、安全、认证计费等的需求,可以利用万兆以太网的校园网组网技术。构建校园网骨干网,实现各个分校区和本部之间的连接,以及实现端到端的以太网访问,提高了传输的效率,有效地保证了远程多媒体教学、数字图书馆等业务的开展。
本文通过分析网络技术特点和目前校园网的普遍需求及实际应用,讲解了校园网络的基本知识,包括路由器、三层交换机、无线AP、服务器等网络设备,VLAN和IP地址,同时对主要设备进行了选型。

ABSTRACT
With the gradual increase need of work data transmission,especially the increase of application data,voice,video and multimedia transmission capacity,the work construction is going in the direction of digitization and campus wireless LAN,however, is an essential part of work, therefore,it plays an important role as a significant supplement of wired campus LAN.
Wireless LAN is very convenient data transmission system,which uses radio frequency technology to replace the old copper twisted-pair posed by local work,allowing users to access its simple structure,information technology players, connect to work anywhere in the world. Wireless local work LAN cables to make up deficiencies,and to achieve the purpose of extending works work technology development carried out almost simultaneously,Universities not only bear the work of teaching,but also bear some of state-level research tasks,taking into consideration the next few years,the development trend work platform, in order to fully meet the colleges and universities for high-speed work,intelligence,security,authentication and accounting needs,etc.,we can use the work Gigabit working of the campus work, the realization of the various campus areas and the connections between the headquarters, as well as end-to-end access and improve the efficiency of the transmission,effectively ensure the long-range
