Non-terrestrial networks are rapidly evolving from experimental satellite systems into an increasingly important part of the global 5G connectivity landscape. This eBook, developed by Radisys in collaboration with TeckNexus, explores how 3GPP standardization, satellite architecture innovation, and software-driven network design are reshaping NTN deployment models. It examines the transition from proprietary systems to standards-based 5G NR approaches, with coverage of transparent and regenerative NTN architectures, mobility management, quasi-Earth fixed and Earth-moving beams, and beam hopping for more efficient resource utilization. The eBook is designed for operators, architects, and industry stakeholders looking to better understand the technical, operational, and performance considerations shaping satellite-enabled 5G connectivity across diverse use cases and geographies.
