  • the base station is an important functional component, responsible for the transmission and reception of radio frequency signals, and the access of wireless signals to the mobile switch center. In some systems, there may also be control functions such as channel allocation and cell management. A base station controls one or several cells.
  • the base station antenna should be reasonably selected according to the actual coverage of the network, such as coverage requirements, traffic distribution, anti-interference requirements and network service quality. Since the choice of antenna type is closely related to terrain, ground objects, and traffic distribution, the antenna usage environment can be roughly divided into five types: urban areas, dense urban areas, suburbs, rural areas, and traffic trunks. In addition, during the setting process of the base station antenna, it is necessary to consider parameters such as the downtilt angle, the direction angle, the antenna hanging height, the antenna diversity distance, and the isolation distance.
  • properly setting the antenna downtilt can not only reduce the influence of co-channel interference, but also effectively control the coverage of the base station and the soft handover ratio of the entire network, and can enhance the signal strength in the coverage area of the base station.
  • the setting of the antenna downtilt is focused on two aspects, namely, focusing on interference suppression and focusing on strengthening the cover. These two aspects focus on different downtilt algorithms. In general, areas with densely distributed base stations should focus on interference suppression, while areas with sparse base stations are focused on considering enhanced coverage.
  • the antenna gain decreases slowly due to the half power angle of the base station antenna. After exceeding the half power angle, the antenna gain (especially the upper lobe) decays very quickly. Therefore, from the viewpoint of controlling interference, it can be considered that the intersection of the extension line of the half power angle to the ground (point B) is the actual coverage edge of the base station.
  • the antenna downtilt setting does not need to consider the influence of factors such as the vertical half power angle due to the fact that the base station is sparsely distributed. Therefore, in order to ensure that there is a sufficiently strong signal at the edge of the coverage area, the intersection of the extension line of the antenna main lobe to the ground (point B) is considered to be the actual coverage edge of the base station.
  • the antenna downtilt setting must also consider the reflection and blocking of nearby mountains, water surfaces and tall glass walls. Therefore, the downtilt angle of a specific base station can be determined by using the above method while being combined with a specific environment.
  • the network staff checks the down-tilt angle of each antenna of the base station one by one, and adjusts the antenna with abnormal tilt angle to adjust the down-tilt angle to the expected configuration value.
  • the main reason for this is that the antenna tilt angle of each base station is manually queried to adjust the antenna with abnormal tilt angle. Not only makes the manual maintenance workload relatively large, but also The adjustment of the abnormally-adjusted ESC antenna depends on the time of artificially active inquiry. If there is no manual inquiry for a long period of time, it may be that the antenna signal coverage is incorrect during this period, which may affect the service communication index. . That is to say, when the external irresistible force (such as typhoon, earthquake, etc.) or human factors (such as artificially reinstalling the ESC antenna) causes the downslope of the base station's ESC antenna to be abnormal, it cannot be guaranteed to be adjusted as soon as possible. For the normal downtilt angle, the stability of the business communication indicators cannot be guaranteed. Summary of the invention
