SuperCell：一种在高塔上使用高增益、高阶扇区化天线的广域覆盖解决方案
SuperCell: A Wide-Area Coverage Solution Using High-Gain, High-Order Sectorized Antennas on Tall Towers
摘要：
在这篇文章中，我们介绍了一种新的解决方案，称为超级细胞，它可以提高投资回报率（ROI）的农村区域网络覆盖。SuperCell提供了两个关键的技术特征：它使用高增益天线的高塔来实现宽覆盖，以及高阶扇区化来实现高容量。我们发现，一个包含超过200米的高海拔平台的解决方案将覆盖范围增加了5倍。结合密集的频率复用，通过使用多达36个方位角扇区从一个位置，我们的解决方案可以充分满足农村覆盖和容量的需求。我们通过传播分析，建模和实验来验证这一点。文章给出了使用不同类型天线的设计视角：Luneburg透镜、有源/无源相控阵和空间复用解决方案。对于每一类，相应的分析模型的信号与干扰加噪声比（SINR）的范围和容量预测。空间复用解决方案也通过现场测量和额外的3D射线跟踪模拟进行了验证。最后，在本文中，我们还阐明了最近使用Luneburg透镜天线系统进行的两次SuperCell现场试验。试验在新墨西哥州和密西西比州的农村进行。在试验中，我们分别量化了SuperCell在贫瘠土地和茂密森林中的覆盖范围和容量。在这篇文章中，我们展示了在试验中获得的结果，并分享了关于绿色领域和棕色领域部署的经验教训。
英文摘要：
In this article we introduce a novel solution called SuperCell, which can improve the return on investment (ROI) for rural area network coverage. SuperCell offers two key technical features: it uses tall towers with high-gain antennas for wide coverage and high-order sectorization for high capacity. We show that a solution encompassing a high-elevation platform in excess of 200 meters increases coverage by 5x. Combined with dense frequency reuse by using as many as 36 azimuthal sectors from a single location, our solution can adequately serve the rural coverage and capacity demands. We validate this through propagation analysis, modeling, and experiments. The article gives a design perspective using different classes of antennas: Luneburg lens, active/passive phased array, and spatial multiplexing solutions. For each class, the corresponding analytical model of the resulting signal-to-interference plus noise ratio (SINR) based range and capacity prediction is presented. The spatial multiplexing solution is also validated through field measurements and additional 3D ray-tracing simulation. Finally, in this article we also shed light on two recent SuperCell field trials performed using a Luneburg lens antenna system. The trials took place in rural New Mexico and Mississippi. In the trials, we quantified the coverage and capacity of SuperCell in barren land and in a densely forested location, respectively. In the article, we demonstrate the results obtained in the trials and share the lessons learned regarding green-field and brown-field deployments.
