Research On Depth Coverage Technology Of LTE Network And Its Applications

In recent years,from technological breakthroughs to commercial applications,China Mobile has been ahead of other Chinese companies in establishing advanced 4G networks in China and has been used for commercial purposes by the end of 2017.More than 1 million 4G base stations have been established in China,and mobile companies have also drawn up plans for the strategic intent of large links during the 13 th Five-Year Plan period,which is scheduled to end on 2020.The total number of links in our country's overall network has doubled or more.This paper focuses on the analysis of the current situation of TDD-LTE network coverage in China's independent intellectual property rights,combined with the major international 4G technologies,as well as the main technologies of wireless communication,and expounds the optimization methods of network coverage,related technologies and application scope.Major problems in the immediate 5G technical filed.In this paper,the author first analyzes the competitive short board of China Mobile in depth coverage,and the challenges in the age of Vo LTE experience,and expounds the negative effects brought by the lack of depth coverage.At the same time,the paper analyzes the difficulties and challenges to solve the problem of inadequate depth coverage.Further,combining with the actual situation,the paper makes a deep research on the depth coverage solutions such as site planning,product solution and parameter optimization,etc.The method is put forward and lied to practice.Considering the actual situation of Gannan,taking the results of Mr measurement as the main means of evaluation,considering the complex field situation and coverage requirements of the network,considering the current network coverage,business proportion and investment value,The four-step method for making the local depth coverage plan and its practical application.In this paper,parameters optimization,neighborhood optimization,double carrier optimization and weak coverage are presented.Optimization,power parameter promotion and LTE characteristic parameter are tested in depth coverage.Finally,combining with the unique physical and chemical scene of Gannan,the paper puts forward the network construction conception of “three layer logical function four layer construction mode”,and finally,the paper puts forward the network construction conception of “three layer logic function four layer construction mode”.Combined with the latest 3D MIMO technology,the experiment is carried out,and the ideal effect is obtained.
