论文摘要
在本文中，我们介绍了WACA，这是第一个同时测量所有24个Wi-Fi通道中能量的系统，该系统允许以微秒尺度粒度在5 GHz处键入通道键合。借助WACA，我们在包括城市热点，住宅社区，大学和一个售罄的体育场（包括98,000名球迷和12,000个同时Wi-Fi连接）的地区进行了首次测量活动。收集的数据集是一个独特的资产，可以在Wi-Fi等多通道技术中找到否则就无法找到见解。为了显示其潜力，我们使用痕量驱动的框架比较了连续和非连接通道键合的性能。我们表明，尽管非连续性优于连续的通道键合的吞吐量（偶尔较大5倍），但它们的平均吞吐量相似。
In this paper, we present WACA, the first system to simultaneously measure the energy in all 24 Wi-Fi channels that allow channel bonding at 5 GHz with microsecond scale granularity. With WACA, we perform a first-of-its-kind measurement campaign in areas including urban hotspots, residential neighborhoods, universities, and a sold-out stadium with 98,000 fans and 12,000 simultaneous Wi-Fi connections. The gathered dataset is a unique asset to find insights otherwise not possible in the context of multi-channel technologies like Wi-Fi. To show its potential, we compare the performance of contiguous and non-contiguous channel bonding using a trace-driven framework. We show that while non-contiguous outperforms contiguous channel bonding's throughput, occasionally bigger by a factor of 5, their average throughputs are similar.
