我们提出了一个广泛的实验评估的性能和功耗的60 GHz的IEEE 802.11ad技术的商用智能手机。我们还将802.11ad与其在5 GHz频段的主要竞争对手802.11ac进行了比较，并首次在移动的设备上对802.11ax进行了比较。我们的性能比较集中在两个方面，还没有被广泛研究之前：（i）密集的多客户端和多AP拓扑结构和（ii）流行的移动的应用程序在现实的移动模式。我们的功耗研究涵盖了非通信和通信模式。我们还提出了第一个研究的省电模式，在802.11ad功能的智能手机和其对性能的影响。我们的研究结果表明，802.11ad能够更好地满足智能手机中新兴带宽密集型应用的需求，而不是5 GHz的同类产品。与此同时，我们确定了几个关键研究方向，以充分发挥其潜力。
We present an extensive experimental evaluation of the performance and power consumption of the 60 GHz IEEE 802.11ad technology on commercial smartphones. We also compare 802.11ad against its main competitors in the 5 GHz band – 802.11ac and, for first time, 802.11ax, on mobile devices. Our performance comparison focuses on two aspects that have not been extensively studied before: (i) dense multi-client and multi-AP topologies and (ii) popular mobile applications under realistic mobility patterns. Our power consumption study covers both non-communicating and communicating modes. We also present the first study of the power saving mode in 802.11ad-enabled smartphones and its impact on performance. Our results show that 802.11ad is better able to address the needs of emerging bandwidth-intensive applications in smartphones than its 5 GHz counterparts. At the same time, we identify several key research directions towards realizing its full potential.
