Project construction cases

This system launches 4 frequency points, 2 frequency points of satellite programs, and one frequency point of city and district respectively, which are transmitted to each station through IP transmission, a total of ten stations, to realize remote control and data detection of each station, including real-time monitoring of air receiver programs. The project is tight in time and difficult in construction, including newly built base stations and frequency-shifted base stations. With the strong support and cooperation of the local bureau, the total project took more than 40 days, and all the projects were completed and reached the acceptance standard. The single frequency network covers a large area, covering the complex terrain and population distribution, and involves the interference processing of the spectrum of the neighboring provinces, cross-regional coverage, and the joint composition of the single frequency network system with several base stations of the national project in the city. This situation is not common in the domestic single frequency network system, so the technical difficulty is great, especially for the antenna feed field coverage technology design, etc. At the same time, the company through field investigation, the antenna field type to do adjustment, the coverage problem has been solved.
