天线倾斜是蜂窝网络最重要的性能调优参数之一，它对蜂窝网络的站点间干扰水平有很大的影响。在本文中，我们分析了天线倾斜对LTE覆盖和容量的影响。通过系统模拟，我们研究了两种倾斜类型（电倾斜和机械倾斜）之间的分布如何影响宏细胞场景中的路径增益和细胞边缘、峰值和平均吞吐量。虽然总倾斜对容量和覆盖都有很强的影响，但我们发现倾斜类型仅对容量有明显的影响。
Antenna tilt is one of the most important performance tuning parameters of a cellular network, since it has a strong impact on the inter-site interference level in the system. In this paper, we present an analysis of the impact of antenna tilt on LTE coverage and capacity. Using system simulations, we study how the distribution between two types of tilt, electrical and mechanical, affects path gain and cell edge, peak, and average throughput in a macro-cellular scenario. While the total tilt has a strong impact on both capacity and coverage, we find that the type of tilt has distinct impact only on capacity.
