校园无线局域网规划

摘要

21世纪网络技术在飞快的发展,伴随着各样电子设备的创新以及用户用途的增加,传统网络技术已经渐渐的不能满足使用的需求。一种计算机网络与无线通信技术相结合的技术靠着具有快捷高效、组网灵活等特点已经在飞速的发展起来,这就是无线网络技术。

无线网络具有许多独特的优势:首先,最重要的是可移动性,它提供了不受线缆限制的应用,用户可以随时随地上网;其次安装容易、WLAN网桥传输系统的安装快速简单,可极大的减少铺设管道及布线等繁琐工作;三是成本低,性价比非常高特别适合于变化频繁的工作场合。;四是上网灵活,无线技术使得WLAN设备可以灵活的进行安装并调整位置,使无线网络达到有线网络不易覆盖的区域。

现在笔记本电脑的普及以及手机等移动设备的发展,为了方便广大师生试用。校园无线网络的建设势在必行。校园网是一个以应用为核心的综合性信息系统,应以高效、安全、易用为原则,充分满足校园扩展需要,确保高吞吐量以及有线网络的无缝集成。通过本论文的介绍,希望大家能对无线网络和校园网更加了解,认识到无线校园网络的重要性。

The campus Wireless LAN Planning

Abstract

Network technology in the 21st century is a rapid development, along with the increase in the use of innovation as well as users of all kinds of electronic equipment, the traditional network technologies have gradually can not meet the demand. The combination of technologies relying on a computer network and wireless communication technology with efficient and flexible networking has been a rapid development, and this is a wireless network technology The wireless network has a number of unique advantages: First of all, the most important is mobility, which provides applications without cable restrictions, the user can access anytime, anywhere; Secondly easy to install, the WLAN bridge transmission system is quick and easy to install, can begreatly reduce the tedious work of laying pipes and wiring, etc.; Third, low cost, and the cost is very high particularly suited to the frequent changes in the workplace. ; Flexible Internet and wireless technology makes the WLAN device can be flexible to install and adjust the position of the wireless network to the wired network is not easy to cover the area.

Laptop now the popularity of mobile phones and other mobile devices, the trial for the convenience of the teachers and students. The construction of the campus wireless network is imperative. The campus network is a comprehensive information system applications at the core, should be efficient, safe, easy-to-use principle, and fully meet the expansion needs of the campus, to ensure high throughput and seamless integration of wired networks. With the introduction of this paper, it is hope that we can learn more about the wireless network and campus network, recognizing the importance of the wireless campus network.
