Democratizing Direct-to-Cell Low Earth Orbit Satellite Networks

Explore the groundbreaking research on democratizing direct-to-cell Low Earth Orbit (LEO) satellite networks in this 18-minute conference talk from NSDI '24. Dive into the challenges of current hop-by-hop stateful cellular sessions and their impact on LEO satellite accessibility. Learn about MOSAIC, an innovative solution that introduces policy-embedded one-time tokens for pay-as-you-go local satellite access. Discover how this approach enables self-serve multi-tenant LEO satellites, simplifies many-to-many service relationships, and allows for on-demand multi-tenancy. Examine the attack-resilient and incrementally deployable aspects of MOSAIC through its SIM-based solution. Gain insights from empirical studies using real satellite data and evaluations with commodity 3GPP NTN protocol stack, validating MOSAIC's viability in revolutionizing global 4G/5G access for phones and IoT devices.
