LTE高站越区覆盖优化方案研究

摘要

针对LTE高站容易导致越区覆盖问题的背景和原因进行分析，探讨了现有解决方案的缺陷，提出了应用大下倾角电调天线的解决方案，并对方案进行了详细分析。通过对方案进行现网实验，结果表明大下倾角天线方案能够有效地解决高站越区覆盖问题，从而提升覆盖效果以及网络性能。%The background and cause of cross-boundary coverage resulting from LTE high station were analyzed. Deficiencies of existing schemes were discussed. A scheme of applying large inclination antenna was proposed and analyzed in detail. The scheme was tested in current network and results show that the proposed scheme not only effectively solves the problem of cross-boundary coverage, but also improves coverage effect and network performance.
