Advanced 5G/6G D2D Services for NTN Training by Tonex
Built for architects and senior engineers, this course unpacks how device-to-device (D2D) communications extend coverage, resilience, and capacity when paired with LEO/GEO constellations and non-terrestrial networks (NTN). You’ll map 3GPP Rel-17/18 features to real deployment choices, from direct-to-device satellite service to hybrid terrestrial–space routing. Cybersecurity receives focused attention: D2D paths can bypass traditional choke points, so we examine trust establishment, key management, and slice isolation in contested environments. We also address jamming resistance, secure sidelink discovery, and integrity of edge breakout functions to protect mission-critical and tactical operations.
