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.<br> <br> 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.<br> 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.<br>本研究旨在采集覆盖广泛的移动宽带（Mobile BroadBand, MBB）网络测速轨迹数据，数据来源为真实用户搭乘公共或私人交通工具在城市中移动时的实测场景。为完成本数据集的采集工作，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。本次轨迹数据主要采集自意大利都灵市，涵盖WiFi、3G、4G三种技术制式，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，且未感知到本次测试行为。本次测试使用搭载安卓（Android）与iOS系统的智能手机作为终端，终端通过传输层的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法：一方面通过移动终端运行重复的主动测量任务（使用iperf2工具），另一方面在服务器端通过tcpdump工具采集被动轨迹。在每一次实验中，移动终端将以上传方向运行iperf2工具持续600秒，同时服务器端的tcpdump将同步捕获网络数据包。 本次采集了意大利多家移动网络运营商的测速轨迹，包括Tim、Wind与Vodafone。针对WiFi网络，我们选用了由Fastweb客户共享其DLS或FTTH家庭网络、通过接入网关自动提供的开源社区WiFi网络WoW-Fi。移动终端将通过IEEE 802.1x协议自动完成身份验证，无需用户进行任何手动操作。时长不足300秒的轨迹均来自静止MONROE节点发起的iperf2实验，或为未成功完成的实验。
