大下倾角天线抑制现网高站过远覆盖问题的分析研究

本文对基站过远覆盖形成的原因以及对网络和用户使用感知带来的负面影响进行了详细阐述。针对此问题,创新性地提出采用大下倾角天线来抑制现网超高基站过远覆盖问题的新思路,并结合现网情况进行了实际应用。分析结果表明,大下倾角天线的波瓣抑制能力能够较好的控制超高基站信号的覆盖距离,为网络优化工作中经常出现并难以解决的过远覆盖、导频污染等问题提供了新的、有效的控制手段。

analysis and research on suppression of over-distance coverage of current network high station by large down angle antenna

This paper describes detailedly the root cause of forming the over-distance coverage of the base station and the negative impact of the user experience. In order to address this problem, this paper presents a new idea of using the large down angle antenna to suppress the issue of over-distance coverage of the existing ultra high base station and performs the practical implementation based on the live network situation. The analysis results show that the suppression capability of the large down angle antenna can control the signal coverage distance of high base station very well, and provides a new, and effective solution to address the over-distance coverage and pilot pollution for the network optimization work.
