Before a dense Wi-Fi network is deployed, Wi-Fi providers must be careful with the performance promises they made in their way to win a bidding process. After such deployment takes place, Wi-Fi-network owners—such as public institutions—must verify that the QoS agreements are being fulfilled. We have merged both needs into a low-cost measurement system, a report of measurements at diverse scenarios and a performance prediction tool. The measurement system allows measuring the actual goodput that a set of users are receiving, and it has been used in a number of schools on a national scale. From this experience, we report measurements for different scenarios and diverse factors—which may result of interest to practitioners by themselves. Finally, we translate all the learned lessons to a freely-available capacity-planning tool for forecasting performance given a set of input parameters such as frequency, signal strength and number of users—and so, useful for estimating the cost of future deployments.

用于测量用户在密集的Wi-Fi部署和容量规划规则中的吞吐量的工具

在部署密集的Wi-Fi网络之前，Wi-Fi提供商必须谨慎对待以其方式赢得投标过程的性能承诺。部署完成后，Wi-Fi网络所有者（例如公共机构）必须验证QoS协议是否得到满足。我们已经将这两种需求合并到一个低成本的测量系统中，在各种情况下的测量报告和一个性能预测工具。该测量系统允许测量一组用户正在接收的实际吞吐量，并且该系统已在全国范围内的许多学校中使用。从这一经验中，我们报告了针对不同场景和各种因素的测量结果，这些测量结果可能是从业人员自己感兴趣的结果。最后，
