Mobile broadband speedtest traces

The goal of this research is to collect a wide range speedtest traces for the mobile broadband (MBB) networks, as seen from actual users while moving around the city using public or private vehicles. For collecting this dataset we ask students to participate and run Mobile BroadBand speedtest. You can find the instruction of our test here. Traces were mostly collected in the city of Torino in Italy, and refer to three technologies (WiFi, 3G, and 4G), and multiple Mobile Network Operators (MNO). The networks were in normal operating conditions (and unaware of our tests). Our terminals (both Android and iOS smartphones) accessed the mobile networks to upload data to a server on campus, using both TCP and UDP at the transport layer. We used a hybrid method in the trace collection process: we run repetitive active measurements from mobile terminals using iperf2, and we collect passive traces on server side using tcpdump. In each experiment, the mobile terminal runs iperf2 in the upload direction for 600 seconds while tcpdump captures packets at the server. We collected traces for different MNOs in Italy (Tim, Wind, and Vodafone). For WiFi, we considered the open WiFi community WoW-Fi offered automatically by Fastweb customers that share their DLS or FTTH home network via the access gateway. Mobile phones automatically authenticate using IEEE 802.1x with no action from the user. Traces shorter than 300 seconds are iperf2 experiments run from the stationary MONROE nodes or failed experiments.本研究的目标是采集广泛的移动宽带（Mobile BroadBand, MBB）网络测速轨迹，数据来源于实际用户乘坐公共或私人交通工具在城市中移动时产生的测速记录。为采集该数据集，我们邀请学生参与并运行移动宽带测速任务，本次测试的操作说明可在此处查阅。 本次采集的轨迹主要来自意大利都灵市，涵盖WiFi、3G与4G三种技术，以及多家移动网络运营商（Mobile Network Operator, MNO）。所有被测网络均处于正常运营状态，且未察觉本次测试活动。我们的终端设备涵盖Android与iOS智能手机，通过传输层的TCP与UDP协议接入移动网络，并向校园内的服务器上传数据。 本次轨迹采集采用混合方案：一方面通过iperf2在移动终端上执行重复性主动测量，另一方面在服务器端使用tcpdump采集被动网络轨迹。每次实验中，移动终端将以上传方向运行iperf2程序600秒，同时服务器端的tcpdump将同步捕获网络数据包。 我们采集了意大利境内多家移动网络运营商的测速轨迹，包括Tim、Wind与Vodafone。对于WiFi网络，我们选取了Fastweb客户通过接入网关共享其DLS或FTTH家庭网络所提供的公开社区WiFi网络WoW-Fi，移动终端将通过IEEE 802.1x协议自动完成身份认证，无需用户进行任何操作。 时长不足300秒的轨迹，均来自静止MONROE节点发起的iperf2实验或失败的实验任务。
