Non-terrestrial networks are moving from experimental satellite systems to an increasingly important part of the 5G connectivity landscape. This eBook, developed by Radisys in collaboration with TeckNexus, examines how NTN is evolving through 3GPP standardization, new deployment architectures, and software-driven approaches to mobility and performance optimization. It gives telecom and satellite stakeholders a practical view of how NTN can support broader coverage, direct-to-device connectivity, and new service opportunities across land, sea, and air.
As satellite and terrestrial networks continue to converge, operators face growing pressure to understand how NTN fits into future 5G strategies. This eBook explains how the shift from proprietary satellite systems to 3GPP-aligned NTN architectures is improving interoperability, expanding use cases, and enabling more standards-based global connectivity. It explores how NTNs can support mobile broadband, IoT, emergency response, maritime and aviation communications, remote connectivity, and broader digital inclusion across underserved areas.
Why This eBook Matters
NTN is no longer a niche topic. It is becoming a strategic area of focus for mobile operators, satellite providers, network architects, and infrastructure vendors. The eBook outlines the practical implications of this shift, including deployment trade-offs, mobility complexity, beam design choices, and the role of software-defined RAN in making NTN more scalable and operationally viable. It also explains how 3GPP Releases 17, 18, and 19 are shaping deployment models for transparent and regenerative architectures.
