【摘要】：WLAN網(wǎng)絡是作為有線網(wǎng)絡的擴展進入人們視野的，隨著WLAN網(wǎng)絡相關協(xié)議的發(fā)展，WLAN網(wǎng)絡相關技術的進步，WLAN網(wǎng)絡產(chǎn)品的廣泛應用，豐富了人類社會的物質文化生活。然而，WLAN網(wǎng)絡應用規(guī)模的擴大以及運營商的廣泛參與使得并不寬裕的WLAN公用帶寬捉襟見肘。用戶增多、頻率資源貧乏、網(wǎng)絡干擾帶來各種各樣的網(wǎng)絡問題，進一步限制著WLAN網(wǎng)絡的健康發(fā)展。由于用戶對網(wǎng)絡質量的要求逐步提高，WLAN網(wǎng)絡優(yōu)化工作的重要性也不斷提升。 WLAN網(wǎng)絡作為公用頻段有其自身的優(yōu)勢與缺陷，如何最大程度的開發(fā)WLAN網(wǎng)絡的優(yōu)勢，規(guī)避、消除、減少WLAN網(wǎng)絡目前存在的缺陷，并結合WLAN網(wǎng)絡應用場景、技術成熟度和發(fā)展趨勢，從終端、網(wǎng)絡部署、投資等方面考慮WLAN網(wǎng)絡優(yōu)化的廣度與深度，作為本文優(yōu)化方法試驗與討論的一個重要環(huán)節(jié)。 本文著重論述WLAN網(wǎng)絡日常優(yōu)化方法的研究，以用戶感知為出發(fā)點和落腳點。通過對廣大用戶提出的普遍問題，結合網(wǎng)絡實際，從WLAN網(wǎng)絡相關協(xié)議發(fā)展進程和關鍵技術的更新?lián)Q代到WLAN組網(wǎng)結構、網(wǎng)絡與終端設備等方面，以工程優(yōu)化、日常優(yōu)化、專項優(yōu)化的方式，從施工質量、網(wǎng)絡結構、網(wǎng)絡覆蓋、網(wǎng)絡容量、傳輸帶寬、頻率、網(wǎng)絡干擾等方面進行優(yōu)化方法的探討與實驗，從而找出問題根本原因，并探討適用于WLAN網(wǎng)絡本身特點的優(yōu)化方法，，逐步改善網(wǎng)絡運行質量。 本文將通過對WLAN網(wǎng)絡優(yōu)化的方法進行研究與探討，通過與相關企業(yè)、運營商的合作，以實驗的方式結合網(wǎng)絡運行實踐，并統(tǒng)計相關的網(wǎng)絡優(yōu)化方法信息，系統(tǒng)描述WLAN網(wǎng)絡優(yōu)化的方法、步驟、流程等，從組網(wǎng)結構、網(wǎng)絡覆蓋、網(wǎng)絡容量、網(wǎng)絡干擾、設備、終端等基礎優(yōu)化入手，探討WLAN網(wǎng)絡基礎優(yōu)化的方法。 由于WLAN在發(fā)展過程中經(jīng)歷了IEEE802.11a、IEEE802.11b、IEEE802.11g、IEEE802.11n協(xié)議的演進，支持不同制式的終端用戶提出的各類問題，成為我們的優(yōu)化對象。因此，在基礎網(wǎng)絡優(yōu)化的基礎上進行數(shù)據(jù)業(yè)務優(yōu)化，提升用戶感知，進一步在WLAN網(wǎng)絡智能化方面做一定的研究與探索。針對運營商、校園、企業(yè)、家庭等不同場景，通過廣泛收集與現(xiàn)場試驗相結合的方式，總結出適合WLAN網(wǎng)絡發(fā)展的優(yōu)化方法、步驟、流程，為WLAN網(wǎng)絡建設和發(fā)展增值、提速。 隨著時代的發(fā)展，技術的進步，移動蜂窩網(wǎng)與WLAN網(wǎng)絡的融合成為未來通信發(fā)展的重要方向，2014年，三大運營商已先后組網(wǎng)建設4G-LTE網(wǎng)絡，這對于WLAN系統(tǒng)來講既是挑戰(zhàn)也是機遇，4G-LTE網(wǎng)絡的建設與發(fā)展將進一步培育數(shù)據(jù)用戶的發(fā)展，使得數(shù)據(jù)用戶的需求將進一步提升，并進一步改變?nèi)藗兊纳钯|量與生活習慣，數(shù)據(jù)業(yè)務的發(fā)展將逐步深入到人們生活的每個角落，WLAN將更加滲透人們?nèi)粘Ｉ畹姆椒矫婷妫琖LAN網(wǎng)絡優(yōu)化工作將更加復雜與深入，優(yōu)化方法的研究與應用的重要性將更加凸顯。
[Abstract]:As the extension of wired network, WLAN network has entered people's field of vision. With the development of WLAN-related protocols, WLAN-related technology has been widely used and enriched the material and cultural life of human society. However, the expansion of WLANs application scale and the wide participation of operators make the limited WLAN public bandwidth overstretched. With the increase of users and the shortage of frequency resources, network interference brings various network problems, which further restricts the healthy development of WLAN network. The importance of WLAN network optimization is improved because of users' demand for network quality. As a common frequency band, WLAN network has its own advantages and disadvantages. How to develop the advantage of WLAN network to the maximum extent, how to avoid, eliminate and reduce the existing defects of WLAN network, and combine with the application scenario of WLAN network, technology maturity and development trend, WLAN network has its own advantages and disadvantages. Considering the breadth and depth of WLAN network optimization from the aspects of terminal, network deployment and investment, it is an important link in the experiment and discussion of the optimization method in this paper. This paper focuses on the research of WLAN network daily optimization method, with user perception as the starting point and foothold. Through the general problems put forward by the vast number of users, combined with the network reality, from the development process and the update of the key technologies of the WLAN network related protocols to the network structure of WLAN, network and terminal equipment, etc., to optimize the engineering and the daily optimization, etc. In order to find out the root cause of the problem, special optimization methods are discussed and experimented in terms of construction quality, network structure, network coverage, network capacity, transmission bandwidth, frequency, network interference, etc. The optimization method suitable for WLAN network itself is discussed to improve the network running quality step by step. This paper will study and discuss the method of WLAN network optimization, through the cooperation with related enterprises and operators, combine the network operation practice with experiment, and statistics the relevant network optimization method information. This paper describes the method, steps, flow chart of WLAN network optimization, discusses the basic optimization method of WLAN network from the aspects of network structure, network coverage, network capacity, network interference, equipment, terminal and so on. Because WLAN has experienced the evolution of IEEE 802.11b, IEEE 802.11g, IEEE802.11n in the process of development, it has become our optimization object to support all kinds of problems raised by different end-users. Therefore, on the basis of the basic network optimization, the data service optimization is carried out, the user perception is improved, and the intelligent WLAN network is further studied and explored. Aiming at different scenarios such as operator, campus, enterprise, family and so on, this paper summarizes the optimization methods, steps and processes suitable for the development of WLAN network through the combination of extensive collection and field test, so as to add value and increase speed for the construction and development of WLAN network. With the development of the times and the progress of technology, the integration of mobile cellular network and WLAN network has become an important direction of communication development in the future. In 2014, the three major operators have successively organized networks to build 4G-LTE networks. This is not only a challenge to WLAN system, but also an opportunity for the construction and development of 4G-LTE network, which will further foster the development of data users, further enhance the needs of data users, and further change people's quality of life and habits. The development of data services will gradually penetrate into every corner of people's lives WLAN will penetrate into all aspects of people's daily life WLAN network optimization work will be more complex and in-depth the research and application of optimization methods will become more important.
