Analysis And Optimization Of WLAN Interference

It is well known that with the rapid development of mobile communication technology and the Internet,mobile communication technology is experiencing the rapid development from 2G,3G to 4G.The number of mobile users is increasing explosively.The WLAN has so much advantages not only because it is not limited by the location of the cable port,but also with the reason that the network is efficient and low-cost,and the WLAN can divert the data traffic effectively.So the WLAN has been developed rapidly and is widely applied in the world.Most of the world's mainstream telecommunications operators use four-wire collaborative network named "2G + 3G + 4G + WLAN" as the main form of full-service operations.With the popularity of WLAN products and their increase,many WLAN terminals may work in the same frequency band because of the WLAN radio frequency domain resources are limited,and the interference between neighboring WLAN products is increasing day by day,which results in the WLAN system performance's degradation.Therefore,WLAN optimization needs to focus on how to avoid interference,weaken the interference,and even coexist with the interference during both the earlier network planing and the network operation period while optimizing the WLAN interference.Based on the principle of various WLAN interference mechanism,this article introduced the key technologies of WLAN network,deeply analyzed the WLAN interference sources and interference types.The impact of various interference sources on access difficulty,network speed and throughput of WLAN access terminals had been discussed.For the pre-construction of WLAN network,this paper summarized the topology of WLAN network and the channel planning in WLAN network while combing with the actual network scheme design.In the WLAN construction process,we encountered a variety of WLAN problems such as difficult to access,slow network speed,throughput decline and so on.So I sorted out the overall flow chart of WLAN network configuration and optimization in this paper to analyze these problems.Take the WLAN programme of Zhangmutou new hotel which i responsible for designing and opening and the WLAN programme of Dongguan Taishang building that i responsible for opening and checking for example,this paper gave the design programme of the new WLAN indoor distribution system and the new + combining road WLAN.After testing and analyzing the mutual interference problems encountered in WLAN operation between the devices existing in the four-network cooperative network,this paper summarized the optimization flow chart of WLAN interference processing and put forward the optimization suggestions.Take the office's slow network speed for example,it combined with the commonly used of test tools to locate the WLAN interference source and the use of software analyzing,summarized how to locate the WLAN interference problems and gave some analysis ideas and pointed out solutions.Take the mobile phone factory in Dongguan for example,this paper focused on the interference problems of open intensive concurrent access scene,put forward recommendations and optimization about analysis and solution of WLAN interference problems.In order to achieve the maximum coverage and minimize the coverage of the interference,this paper proposed to use the 2.4G + 5.8G hybrid network,and run with the low power expansion coverage,to avoid interference and achieve the maximum network capacity and performance.
