摘要：21世纪，我们正处在科学信息通信技术发展的高峰时期，为了让人们达到更灵活，便利，高速的网络使用目的，无线局域网因此诞生，并逐步融入到人们生活的方方面面。手机、平板电脑、笔记本电脑甚至是台式电脑都加入了无线局域通信的电子模块，使得只要有无线局域网基站信号覆盖的地方，都能随意连接internet进行上网冲浪。不过目前无线局域网络技术虽处于发展高峰期，但是依然存在较大安全和技术上的缺陷，使得上网的速度和加密性受到到一定量限制，信号覆盖率也有待提升。

　　　本文对无线局域网络这一近年来迅猛发展的新生产业进行从表面的发展历史到深入的技术解析，再到现实中的组建实用进行了尽可能详细的说明。让读者能对无线局域网络有全面深层的认识和了解和对学院尝试进行设计。

Abstract：In the 21st century, we are living in scientific information communication technology development rush age, and in order to let people achieve a more flexible, convenient, high-speed Internet use purpose, the wireless local area network was born, and gradually into all aspects of people's lives. Mobile phone, PAD, laptop and even desktop computer had been installed the electronic module of wireless local area communication. There is the wireless local area network stations signal coverage of place, we can connect to Internet surfing the Internet at will. Nowadays, the wireless local area network technology is a development peak, but still there are many safety and technical flaws, makes the Internet speed and encryption received a certain amount limitation, signal coverage to ascend.

　　　In this paper, the wireless local area network which is the development of new industries, we will begin with the development history to the surface to the in-depth technical analysis, and then to the reality of a practical as far as possible the detailed instructions. Let the reader can have a comprehensive understanding of the deep and understanding on the wireless local area network and try to set up one for SCNUZC.

　　　无线局域网的发展无疑给我们的生活带来了极大的便利。并且当技术的不断改进和提升，无线局域网最终将取代有线局域网络传输的地位，让网络用户能随时随地结合小巧轻便的移动数码产品高速安全的浏览网络信息。通过对无线局域网络的总体了解，不仅能让我们知道无线局域网是如何从发明发现到普遍运用，更能在现有无线局域网络的基础之上进行突破和升级，让人类无限的知识能更广泛的共享，早日实现无线局域网络全球覆盖化。

在本次论文设计中，对无线局域网络进行尽可能深刻的理解和认识，需要查阅大量现有书籍资料，并在家中、学校、大型超市和通信营运商等方面对无线局域网进行探究和了解。
