Satellite Constellations for Direct-to-Device Service Fundamentals Training by Tonex
Modern networks are racing to bridge space and smartphones—this course equips you to design the constellation side of Direct-to-Device services with confidence. You will learn how to select orbits, size footprints, steer beams, and route traffic across inter-satellite links while meeting handset constraints. Security is integral throughout. We discuss jamming resilience, interference containment, and secure cross-link routing so the constellation protects data from space to pocket. Expect practical trade studies that balance coverage, capacity, and cost, alongside cybersecurity measures that harden control and user planes against evolving threats.
