| Traditional mobile communication companies have changed their business to the big data since the industry restructuring and the licensing of 4G.The operators are taking up to changing their strategic targets from "The Expert of Mobile Communication" to "The Expert of Mobile Information".The business in the future will be the world of the big data,big throughput and the high bandwidth.Due to the limitations of traditional mobile communications,tariff packages,the major operators have increased WLAN network construction and operation.With the character of movability,high rate and the IP-based network structure of WLAN,they can cover the shortages of the data business.With the breakthrough point of expanding the business of broadband access,WLAN can make the operators to achive the goal of full business operation.Howerver,there are many shortages in the special application of WLAN belowing beacause of the boundedness in WLAN itself:1.signal intensity in the user side is not stable.2.user connect or disconnect WLAN frequently is a serious problem.3.Download speed is low and have time delay.4.perceptibility is low.All these appearances are caused by signal interference and unreasonable parameter setting.The core content in this article is to confirming the influence of same channel interference and adjacent channel interference based on the research of WLAN protocol and wireless communication technique,and the analysis of operation problems on WLAN.In addition,it achieved the quantitative analysis of same channel interference and adjacent channel interference based on repearing the interference,simulating the network environment,constructing the test platform.The goal of this research is summing up a set of parameter configuration standards that can be applied to different kind of WLAN circumstances.Further more,based on the theory and practice data,it used to finish the network optimization for colleges and universities,and provide a reference for the other circumstances. |
