【摘要】：近年来,基于WLAN无线通信技术的无线局域网取得了飞速发展,已成为组建无线校园网的主流技术。目前伴随着国家互联网+的概念逐步渗透到国民经济中的各个领域,大部分高、中等院校目前正在加紧对信息化教育的规划和建设,作为有线校园网络的延伸,无线校园网已成为数字化校园的基础,学生和教师日益增长的网络需求,对无线校园网络建设提出了巨大的挑战。本论文首先概述了无线局域网的发展历程,对比了无线局域网的相关技术标准,分析了无线局域网组网的关键技术,研究了无线局域网的安全措施。重点以XX专科学校无线校园网建设为背景,指出了传统的校园网的存在的一些问题,结合目前校园网应用现状,通过对学校广大师生无线上网需求的调研,得出了无线校园网建设的必要性,并分析了无线校园网建成后广阔的应用需求。在此基础上提出了一套完整的的无线校园网的设计方案,在设计方案中对无线校园网的设计原则、设计目标、覆盖方案、信道规划、无线认证、网络管理、网络安全、工程设备选型、施工工艺等方面进行了详细的论述。根据校园里不同建筑物、不同覆盖场景提出了室内、室外具体的点位部署方案,室内覆盖根据信号穿越障碍物的衰减原理,结合建筑物的不同结构采用多个AP连接全向或定向天线部署在走廊天花板上,来实现室内各个房间区域的全覆盖。室外则采用高功率的室外AP连接高增益定向天线,实现对篮球场、运动场等室外空间覆盖。论文针对校园内的每种应用场景制定了单独的规划设计方案,绘制了每栋建筑物的具体工程施工图纸,工程实施结束后,对运行中的无线校园网进行了整体测试,给出了优化解决方案,保障了网络的高效、平稳的运行。本论文从先期工程勘察到后期具体工程设计中,都结合学校当前教学的实际需要,做出了科学合理的网络规划部署,满足了校园无线网络的应用需求和拓展需求。通过工程施工后的网络运营表明工程方案设计合理、能够满足广大师生的日常上网需求,达到预期效果,并且衍生出很多人性化的无线应用需求。全文具体的呈现了网络需求分析、技术设备选型、整体规划设计、工程实现优化的整个过程,为今后的无线校园网工程设计提供了可以借鉴的思路。
[Abstract]:In recent years, WLAN based on WLAN wireless communication technology has made rapid development, and has become the mainstream technology of establishing wireless campus network. At present, the concept of national Internet has gradually penetrated into all fields of the national economy. Most of the high and middle schools are now stepping up the planning and construction of information education. As an extension of the wired campus network, the wireless campus network has become the basis of the digital campus, and the growing network needs of students and teachers. This paper first summarizes the development of WLAN, compares the related technical standards of WLAN, and analyzes the key technologies of WLAN networking. In this paper, the security measures of WLAN are studied. Based on the construction of wireless campus network in XX College, some problems of traditional campus network are pointed out, and the current application situation of campus network is combined. Through the investigation and research on the demand for wireless internet between teachers and students, the necessity of the construction of wireless campus network is obtained. Based on the analysis of the wide application requirements of wireless campus network, a complete design scheme of wireless campus network is put forward. In the design scheme, the design principle, design goal and coverage scheme of wireless campus network are introduced. Channel planning, wireless authentication, network management, network security, engineering equipment selection, construction technology and other aspects are discussed in detail. According to the attenuation principle of the signal passing through the obstacle, the indoor coverage is arranged on the ceiling of the corridor with multiple AP connection omnidirectional or directional antennas according to the different structure of the building. Outdoor use of high power outdoor AP connection high gain directional antenna, to achieve the basketball court, The paper makes a separate plan and design plan for each application scene in the campus, and draws the concrete construction drawings of each building, and after the implementation of the project, The wireless campus network in operation is tested as a whole, and the optimized solution is given to ensure the efficient and stable operation of the network. According to the actual teaching needs of the school, scientific and reasonable network planning and deployment have been made to meet the needs of campus wireless network application and expansion. The network operation after construction shows that the project design is reasonable. Can meet the daily needs of teachers and students, achieve the desired results, and derive a lot of humanized wireless application requirements. The full text presents the network demand analysis, the selection of technical equipment, the overall planning and design. The whole process of engineering optimization provides a reference for the future wireless campus network engineering design.
