【摘要】：WLAN网络是作为有线网络的扩展进入人们视野的，随着WLAN网络相关协议的发展，WLAN网络相关技术的进步，WLAN网络产品的广泛应用，丰富了人类社会的物质文化生活。然而，WLAN网络应用规模的扩大以及运营商的广泛参与使得并不宽裕的WLAN公用带宽捉襟见肘。用户增多、频率资源贫乏、网络干扰带来各种各样的网络问题，进一步限制着WLAN网络的健康发展。由于用户对网络质量的要求逐步提高，WLAN网络优化工作的重要性也不断提升。 WLAN网络作为公用频段有其自身的优势与缺陷，如何最大程度的开发WLAN网络的优势，规避、消除、减少WLAN网络目前存在的缺陷，并结合WLAN网络应用场景、技术成熟度和发展趋势，从终端、网络部署、投资等方面考虑WLAN网络优化的广度与深度，作为本文优化方法试验与讨论的一个重要环节。本文着重论述WLAN网络日常优化方法的研究，以用户感知为出发点和落脚点。通过对广大用户提出的普遍问题，结合网络实际，从WLAN网络相关协议发展进程和关键技术的更新换代到WLAN组网结构、网络与终端设备等方面，以工程优化、日常优化、专项优化的方式，从施工质量、网络结构、网络覆盖、网络容量、传输带宽、频率、网络干扰等方面进行优化方法的探讨与实验，从而找出问题根本原因，并探讨适用于WLAN网络本身特点的优化方法，，逐步改善网络运行质量。本文将通过对WLAN网络优化的方法进行研究与探讨，通过与相关企业、运营商的合作，以实验的方式结合网络运行实践，并统计相关的网络优化方法信息，系统描述WLAN网络优化的方法、步骤、流程等，从组网结构、网络覆盖、网络容量、网络干扰、设备、终端等基础优化入手，探讨WLAN网络基础优化的方法。由于WLAN在发展过程中经历了IEEE802.11a、IEEE802.11b、IEEE802.11g、IEEE802.11n协议的演进，支持不同制式的终端用户提出的各类问题，成为我们的优化对象。因此，在基础网络优化的基础上进行数据业务优化，提升用户感知，进一步在WLAN网络智能化方面做一定的研究与探索。针对运营商、校园、企业、家庭等不同场景，通过广泛收集与现场试验相结合的方式，总结出适合WLAN网络发展的优化方法、步骤、流程，为WLAN网络建设和发展增值、提速。随着时代的发展，技术的进步，移动蜂窝网与WLAN网络的融合成为未来通信发展的重要方向，2014年，三大运营商已先后组网建设4G-LTE网络，这对于WLAN系统来讲既是挑战也是机遇，4G-LTE网络的建设与发展将进一步培育数据用户的发展，使得数据用户的需求将进一步提升，并进一步改变人们的生活质量与生活习惯，数据业务的发展将逐步深入到人们生活的每个角落，WLAN将更加渗透人们日常生活的方方面面，WLAN网络优化工作将更加复杂与深入，优化方法的研究与应用的重要性将更加凸显。
[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.
