据我们所知，我们对智能手机上的商用5G性能进行了首次测量研究，仔细研究了美国三个城市的三家运营商（两家毫米波运营商，一家中频运营商）的5G网络。我们在不同的城市环境中对5G性能进行了广泛的现场测试。我们系统地分析了5G中的切换机制及其对网络性能的影响。我们探讨了使用位置和可能的其他环境信息来预测网络性能的可行性。我们还研究了5G上的应用程序性能（Web浏览和HTTP下载）。我们的研究消耗了超过15 TB的蜂窝数据。在5G刚刚亮相时进行，它为研究5G性能如何演变提供了“基线”，并确定了以跨层方式改善5G用户体验的关键研究方向。我们已经在https://fivegophers.umn.edu/www20上发布了从我们的研究（称为5Gophers）中收集的数据。
We conduct to our knowledge a first measurement study of commercial 5G performance on smartphones by closely examining 5G networks of three carriers (two mmWave carriers, one mid-band carrier) in three U.S. cities. We conduct extensive field tests on 5G performance in diverse urban environments. We systematically analyze the handoff mechanisms in 5G and their impact on network performance. We explore the feasibility of using location and possibly other environmental information to predict the network performance. We also study the app performance (web browsing and HTTP download) over 5G. Our study consumes more than 15 TB of cellular data. Conducted when 5G just made its debut, it provides a “baseline” for studying how 5G performance evolves, and identifies key research directions on improving 5G users’ experience in a cross-layer manner. We have released the data collected from our study (referred to as 5Gophers) at https://fivegophers.umn.edu/www20.
