摘 要
无线通信和Internet技术的迅速发展给人们的生活方式和生活质量带来了巨大的变化，越来越多的用户希望在移动过程中高速接入Internet，浏览新闻、收发电子邮件、欣赏多媒体影音、聊天、对战网络游戏，不受空间时间限制地享受生活的乐趣。无线局域网作为一种网络接入手段，以其频带免费、组网灵 活、易于迁移等优点，成为无线通信与Internet技术相结合的新兴发展方向 之一。
本文侧重实际应用，覆盖校园内部分区域，为教学和学习生活提供切实可用的无线网络环境；全面的无线网络支撑系统（包括无线网管、无线安全，无线计费等），以避免无线设备及软件之间的不兼容性或网络管理的混乱而导致的问题；保证网络访问的安全性；安全、认证；覆盖要求方面主要包括学生在宿舍外学习的地方，包括图书馆、饭堂、操场及运动场、以及校园各个小区；实现对用户管理、认证、控制功能；实现无线接入所需布设的无线路由器通过校园网的汇聚层设备接入到校园网中，在汇聚层都提供相应的接口给无线网；室内工程布线与安装要确定好较为开阔位置，将网线走暗线铺设到位，无线路由器可利用设备本身自带的安装附件进行安装；如果需要遮蔽，则需要定制非金属安装盒；如果是挂在天花板上，则根据天花板的情况而定，若天花板是非金属结构，可以固定在天花板内。

Abstract
The rapid development of wireless communications and Internet technology to people's lifestyle and quality of life brought great changes, more and more users want in the process of moving, high-speed access to the Internet, browse news, e-mail, enjoy multimedia,Chat, an online game, enjoy life from space time limit. Wireless local area network as a means of network access, with its band free, flexible networking, and easy migration etc., to become the emerging development direction of one of the combination of wireless communications and Internet technology.
This paper focuses on the practical application, covering part of the area within the campus, effectively available wireless network environment for teaching and learning life; comprehensive wireless network support systems (including wireless network management, wireless security, wireless billing, etc.), in order to avoid wireless devices and confusion and lead to incompatibilities between the software or network management issues; guarantee the security of the network access; safety and certification; coverage requirements, including students learning outside the hostel, including a library, dining hall, playground and playground, as well as campus each cell; achieve user management, authentication, control functions; achieve wireless router via the campus network convergence layer devices access to the campus network, wireless access required emplaced in the convergence layer provides the interface to wireless network; wiring and installation of interior work to determine better the more open position, the cable go dark line laying in place the wireless router device comes with its own mounting accessories available to install; if you need shelter, you need to customize the non-metallic mounting box; if hanging from the ceiling, the ceiling, if the ceiling is a non-metallic structure, can be fixed in the ceiling.
