【摘要】：近年來,基于WLAN無線通信技術(shù)的無線局域網(wǎng)取得了飛速發(fā)展,已成為組建無線校園網(wǎng)的主流技術(shù)。目前伴隨著國家互聯(lián)網(wǎng)+的概念逐步滲透到國民經(jīng)濟中的各個領(lǐng)域,大部分高、中等院校目前正在加緊對信息化教育的規(guī)劃和建設(shè),作為有線校園網(wǎng)絡(luò)的延伸,無線校園網(wǎng)已成為數(shù)字化校園的基礎(chǔ),學(xué)生和教師日益增長的網(wǎng)絡(luò)需求,對無線校園網(wǎng)絡(luò)建設(shè)提出了巨大的挑戰(zhàn)。本論文首先概述了無線局域網(wǎng)的發(fā)展歷程,對比了無線局域網(wǎng)的相關(guān)技術(shù)標準,分析了無線局域網(wǎng)組網(wǎng)的關(guān)鍵技術(shù),研究了無線局域網(wǎng)的安全措施。重點以XX�？茖W(xué)校無線校園網(wǎng)建設(shè)為背景,指出了傳統(tǒng)的校園網(wǎng)的存在的一些問題,結(jié)合目前校園網(wǎng)應(yīng)用現(xiàn)狀,通過對學(xué)校廣大師生無線上網(wǎng)需求的調(diào)研,得出了無線校園網(wǎng)建設(shè)的必要性,并分析了無線校園網(wǎng)建成后廣闊的應(yīng)用需求。在此基礎(chǔ)上提出了一套完整的的無線校園網(wǎng)的設(shè)計方案,在設(shè)計方案中對無線校園網(wǎng)的設(shè)計原則、設(shè)計目標、覆蓋方案、信道規(guī)劃、無線認證、網(wǎng)絡(luò)管理、網(wǎng)絡(luò)安全、工程設(shè)備選型、施工工藝等方面進行了詳細的論述。根據(jù)校園里不同建筑物、不同覆蓋場景提出了室內(nèi)、室外具體的點位部署方案,室內(nèi)覆蓋根據(jù)信號穿越障礙物的衰減原理,結(jié)合建筑物的不同結(jié)構(gòu)采用多個AP連接全向或定向天線部署在走廊天花板上,來實現(xiàn)室內(nèi)各個房間區(qū)域的全覆蓋。室外則采用高功率的室外AP連接高增益定向天線,實現(xiàn)對籃球場、運動場等室外空間覆蓋。論文針對校園內(nèi)的每種應(yīng)用場景制定了單獨的規(guī)劃設(shè)計方案,繪制了每棟建筑物的具體工程施工圖紙,工程實施結(jié)束后,對運行中的無線校園網(wǎng)進行了整體測試,給出了優(yōu)化解決方案,保障了網(wǎng)絡(luò)的高效、平穩(wěn)的運行。本論文從先期工程勘察到后期具體工程設(shè)計中,都結(jié)合學(xué)校當前教學(xué)的實際需要,做出了科學(xué)合理的網(wǎng)絡(luò)規(guī)劃部署,滿足了校園無線網(wǎng)絡(luò)的應(yīng)用需求和拓展需求。通過工程施工后的網(wǎng)絡(luò)運營表明工程方案設(shè)計合理、能夠滿足廣大師生的日常上網(wǎng)需求,達到預(yù)期效果,并且衍生出很多人性化的無線應(yīng)用需求。全文具體的呈現(xiàn)了網(wǎng)絡(luò)需求分析、技術(shù)設(shè)備選型、整體規(guī)劃設(shè)計、工程實現(xiàn)優(yōu)化的整個過程,為今后的無線校園網(wǎng)工程設(shè)計提供了可以借鑒的思路。
[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.
