[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.
