Research On Optimization And Applications Of 5th Generation Mobile Communication Network In YunNan Province

At present,we are entering a new era of rapid development of mobile communication,4G network has become an essential part of people's life,4G network is facing a geometric explosion of data traffic growth,has reached the bottleneck of development,the emergence of 5G network,is to break the deadlock sword.5G network is based on the current and future communication reform and the hot spot of global research and development.Taking the 5G network optimization and industrial application as the research background,this paper analyzes and studies the key technologies of 5G network in Yunnan Mobile Company's large-scale construction,optimization,application and promotion of 5G.The 5G network scheme,5G network optimization and application system design of Yunnan Mobile are completed,and the future application of 5G technology in all walks of life is forecasted.The main work of this paper is as follows:(1)The key technologies of 5G network,such as large-scale antenna array,ultra-dense networking,new multi-carrier,and simultaneous and same-frequency full duplex,are analyzed,providing theoretical support for the design of 5G network scheme.(2)In view of the problems such as unreasonable spectrum allocation,insufficient room resources and insufficient optical fiber core in the large-scale 5G construction of Yunnan Mobile,combined with the current network situation in Yunnan,the spectrum planning scheme and the threelayer three-dimensional network scheme design of 5G network are completed.(3)In 4G and 5G hybrid network with the same frequency interference,local area network capacity is insufficient,the problems of overlapping coverage analysis,through the optimization of the network capacity of an office building,testing,optimization formulation,project implementation from the network,open access equipment,engineering testing the whole process has carried on the practice,has achieved expected effect of optimization.(4)The research analyzed the 5G network,the key technology in industrial,medical,transportation and other industries the application principle,in Yunnan province for 5G unmanned aerial vehicle(uav),5G remote monitoring applications such as display,at the same time to build 5G video platform equipment,core network,interactive media optimization,engineering test has carried on the practice,the practice of the desired effect.(5)It analyzes how to integrate 5G network with traditional industries,how to make innovations in 5G business application in the digital transformation process of the whole industry,and prospects the business applications of several emerging vertical industries covered by 5G network.
