Zhengzhou Days Feed System Optimization Design

The main structure of wireless communication system is present based on the development of mobile communication system, and by analyzing the mobile base station feedback system and relating the theory of electro magnetic radiation, the article introduces the antenna theory and feedline system. Precisely mean to the antenna radiation parameter and circuit parameter. Then, the antenna patterns and technique characteristics are proposed, and for the deferent scenes, the article brings to the criterion about the antenna selection. Additionally, antenna radiation parameter and circuit parameter are analyzed with the effects to the network quality. Because of the important effects, the article analyzes the structure, craft and practical material of the base station antenna. For the elements to affect the network quality, the article proposes the reasonable advice to eliminate the interference, which solves the weak and strong coverage in the current communication network. By the measurement and treatment, build up the feedback files and clear up the main interference in the inside and outside network.In order to check the effect of the feedback treatment and optimization, KPI/DT is monitored and compared to analyzing. In the process of feedback optimization and adjustment, the emphasis on the statistical analyzation, tracing of KPI and auxiliary DT is our main job, which is to inspect the affect of the feedback optimization and adjustment. Form the view of the KPI, the affect is observed, and in some else regions, the affect is not reflected from the KPI, but the result is pick up by DT data, compare to the affect of coverage with front and back optimization. Finally, the author analyzes the network indicators after the antenna replacement in the area of the urban district and major roads, summarizes the key issues in the project and proposes the five-year project plan to exchange the antenna.
