Pervasive connectivity is an essential underlying substrate for smart cities, leading municipalities to start programs where Wi-Fi is the fundamental building block to develop public Municipal Wireless Networks. Even though hundreds of cities around the world offer some form of Wi-Fi access, there are no widely available results regarding the network Quality of Service (QoS), user Quality of Experience (QoE), and overall utilization profile. The Municipality of São Paulo operates a free Wi-Fi Internet program in 120 public spaces called digital squares. We collected user connection data, network performance, and service availability for more than 2 years from the 120 squares and undertook experiments with video streaming in five squares. We used this unique large dataset to evaluate the impact of current admission control practices in public Wi-Fi networks on the network QoS, user QoE and service availability, also providing insights into the most common QoS/QoE issues and their causes. We also leveraged the data set to establish and verify a correlation between the number of users access in the network and specific events occurring in the area.

大型市政无线网络分析

普及连接是智慧城市的重要基础,领导城市在Wi-Fi是发展公共市政无线网络的基本要素的情况下启动计划。即使世界上数百个城市都提供某种形式的Wi-Fi接入,但是有关网络服务质量(QoS),用户体验质量(QoE)和总体利用率配置文件并没有广泛可用的结果。圣保罗市政府在120个称为数字广场的公共场所提供免费的Wi-Fi互联网程序。我们从120平方开始收集了两年多的用户连接数据,网络性能和服务可用性,并进行了五个平方的视频流实验。我们使用这个独特的大型数据集来评估公共Wi-Fi网络中当前准入控制做法对网络QoS,用户QoE和服务可用性的影响,还可以洞悉最常见的QoS / QoE问题及其原因。我们还利用数据集来建立和验证网络中的用户访问数量与该地区发生的特定事件之间的相关性。
