大规模 MIMO 技术通过增加基站天线的数量，有望将无线移动网络的容量提高许多倍。因此，它已成为即将推出的第五代（5G）移动网络的关键技术。之前的工作主要集中在构建概念验证系统以展示大规模 MIMO 的可行性及其优势。然而，要证明大规模 MIMO 在大规模密集部署中的性能，仍有大量工作要做。在本文中，我们介绍了构建 ArgosNet 的经验，ArgosNet 是一个可扩展的多小区校园范围大规模 MIMO 测试平台。 ArgosNet 的目标是在现实的大规模环境中为该技术提供可扩展性、可编程性和易于部署性。我们介绍了我们在构建 ArgosNet 时所做的设计选择，并提供了它们如何帮助我们实现这些目标的详细信息。通过表征主要组件的性能，我们讨论了 ArgosNet 如何释放我们进行现有系统无法进行的研究的能力。
Massive-MIMO technology promises many-fold improvement in the capacity of wireless mobile networks by scaling up the number of base station antennas. Hence, it has become a key technology for upcoming fifth generation (5G) mobile networks. Previous work has mainly focused on building proof-of-concept systems to show the feasibility of massive-MIMO and its benefits. However, much work remains to demonstrate the performance of massive-MIMO in at-scale dense deployments. In this paper, we present our experience in building ArgosNet, a scalable multi-cell campus-wide massive-MIMO testbed. The goal of ArgosNet is to provide scalability, programmability, and ease of deployment for this technology in realistic large-scale environments. We present the design choices we made in architecting ArgosNet and provide details in how they helped us achieve these goals. By characterizing the performance of major components, we discuss how ArgosNet unlocks our ability to do research that is not possible with existing systems.
