论文摘要
使用基于地面的蜂窝网络为机载系统提供宽带连接是一种有前途的解决方案，因为它比基于卫星的解决方案具有多个优势。但是，有限范围的地面基站是完全实现这种方法的关键挑战。本文通过提出一个数学框架来解决此问题，以扩展范围扩展，利用基站的大量天线。与以前的作品相反，范围不被视为设计参数，我们将信号与噪声比的建模是天线数量的函数以及视线距离地面到空中系统中的范围。这使我们能够得出分析表达式，以确定在不同频段以及跟踪和非跟踪方案中增加范围所需的天线数量。
Providing broadband connectivity to airborne systems using ground based cellular networks is a promising solution as it offers several advantages over satellite-based solutions. However, limited range of terrestrial base stations is a key challenge in full realization of this approach. This paper addresses this problem by proposing a mathematical framework for range extension leveraging large number of antennas at the base station. In contrast to prior works where range is not considered as a design parameter, we model the signal to noise ratio as a function of both number of antennas as well as the range in line-of-sight ground-to-air systems. This allows us to derive analytical expressions to determine the number of antennas required to increase range in different frequency bands and tracking and non tracking scenarios.
