Optimization Strategy and Case Analysis of 5G NSA Wireless Network

Abstract

In June 2019, the Ministry of Industry and Information Technology issued 5G commercial licenses to China Telecom, China Mobile, China Unicom and China Radio and Television, which marked the official entry of China into the first year of 5G commercial use and the penetration of 5G into every corner of social life, redefining traditional industries, improving efficiency and reducing costs, which will better change society. In this paper, first of all, the principle of 5G NSA wireless network optimization, the causes of coverage optimization and optimization methods were discussed in detail based on the architecture of 5G NSA wireless network system. Secondly, in view of the common coverage problems in a city, the main problems existing in the network area were judged through the statistics and analysis of the main indicators of the network, and the network optimization was effectively implemented by means of adjusting the downward inclination angle and the azimuth angle of the antenna, and adjusting the power of the reference signal, thereby improving the utilization rate of network resources and the performance of the network, and effectively improving the performance of the network and the user experience. Based on the actual work, the different problems in the optimization of 5G NSA wireless network were analyzed, and the practical solutions were given, which are practical.
