Design And Implementation Of The Configuration Function In Wlan Spectrum Analysis Sub-Sysytem

As the highly rapid development of Internet, it accelerated the application of the mobile Internet. At the same time, the popularity of mobile terminals has brought the rapid development of wireless local area network (WLAN). At present, the wire equipment becomes more and more popular. However, it makes the application environment of WLAN become more complicated. Hence, the analysis for interference of non-WLAN signals in the wireless local area network environment is an effective means for improving the quality of the wireless spectrum.Wireless frequency channel used by WLAN equipment is open. Meanwhile, there are many wireless signals of other equipment. However, those signals are potential interference sources of the WLAN signal. The main task of this study is to develop a spectrum analysis system based on AP (Access Point). Spectrum analysis system for WLAN is a distributed system, where the network equipment is connected by wired or wireless. To keep the normal WLAN application in the WLAN environment, the most important work is to keep the real-time monitoring of the channel quality, which can effectively avoid low efficiency problem brought by interference signals.The solution of the above problem is to develop a WLAN spectrum analysis system. The highlight of this paper is the design and implementation of the configuration function module of a WLAN spectrum analysis system. Many configuration tools can be used in the process of configuration management of wireless devices. In this paper, three common configuration methods will be introduced, which include the command line configuration, MIB configuration and WEB configuration. The configuration function of a WLAN spectrum analysis system is the precondition of keeping the normal work of the system. After configuring all the parameters of the spectrum analysis system, non-WLAN signal data can be collected from AC, then the data is processed on the AC, and sent to the spectrum analysis and management software for drawing the spectrogram.This paper analyzes the implementation process of various configuration function, including requirements analysis, detailed design and the function implementation, according to standards of the software engineering development process.
