In this repository, we release the dataset and tools in CoNEXT '23 paper, LEO Satellite vs. Cellular Networks: Exploring the Potential for Synergistic Integration.
In this work, we present a measurement study of the Starlink LEO satellite network in comparison with cellular networks, aiming to uncover the potential for synergistic integration. Through a large-scale data collection campaign and in-depth analysis, we (1) identify the performance characteristics of two Starlink configurations, (2) evaluate the coverage of the current Starlink deployment compared to major cellular carriers, and (3) investigate the potential benefits of enabling multipath using both LEO satellite and cellular networks.
To help you easily obtain the figures presented in this paper, we have provided complete scripts and processed data, which come with detailed instructions. The folders and files are organized in the order of the figures as they appear in the paper. Most of the figures can be generated by simply running a single command.
We use the Mobility (MOB) and Roam (RM) plans of Starlink and three cellular carriers, together with three cellular carriers in ths US. We use five smartphones, each connected to one of these services.
We perform extensive drive tests across major cities and interstate freeways in the US. It encompasses diverse geographical regions, including densely populated urban areas with tall buildings and open rural areas with minimal obstructions.
