While the digital divide still persists across social, economic, and geographic boundaries, low-earth orbiting (LEO) satellite networks show great promise in bridging the Internet connectivity gap. These networks feature a dense constellation of satellites that orbit at low altitudes, allowing users to bypass many challenges of terrestrial connectivity by transmitting packets directly to space. As a result, LEO network companies like Starlink, Project Kuiper (Amazon), and OneWeb frequently advertise their ability to bridge the connectivity gap. 

In this talk, we introduce a measurement study with the goal of understanding how well Starlink, the most widely deployed LEO network, is actually able to improve Internet access in low income and remote regions. Using a combination of data from speed tests, traceroutes, and custom simulations, we show that Starlink, like similar attempts to reach low income and remote regions, is still an incomplete solution as currently deployed. However, our findings regarding client to edge server mapping and inter-satellite link deployment suggest that there are clear opportunities for improvements in these regions.
