无人机（UAV）既是未来无线网络的推动者，也是未来无线网络的用户。它经历与地面上的无线电节点不同的无线电传播条件。因此，重要的是实验研究蜂窝通信和网络创新的性能，同时服务于空中无线电。在本文中，我们研究了由开源软件定义无线电（SDR）网络服务的低空空中节点的性能。我们提供了一个开源的硬件和软件组件建立基于SDR的宽带无线链路所需的详细描述，并提出无线电性能测量。我们对符合标准的软件定义4G系统的研究结果表明，利用商用现成硬件、开源软件和低功耗信令，为无人机通信和网络创新提供先进的无线测试平台是可行的。
An unmanned aerial vehicle (UAV) is both an enabler and user of future wireless networks. It experiences different radio propagation conditions than a radio node on the ground. Therefore, it is important to experimentally investigate the performance of cellular communications and networking innovations while serving aerial radios. In this paper, we examine the performance of low-altitude aerial nodes that are served by an open-source software-defined radio (SDR) network. We provide a detailed description of the open-source hardware and software components needed for establishing an SDR-based broadband wireless link, and present radio performance measurements. Our results with a standard compliant software-defined 4G system show that an advanced wireless testbed for innovation in UAV communications and networking is feasible with commercial off-the shelf hardware, open-source software, and low-power signaling.
