Abstract
Low-Earth-Orbit (LEO) satellite networks, such as Starlink, are transforming global network connectivity by bringing Internet access to remote and underserved areas. However, the current coverage and performance of the LEO satellite network service compared with those of cellular networks are under-explored. 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.
