5G Non-Terrestrial Networks Enable Ubiquitous Global Connectivity
Дата публикации: 30-03-2026 10:00:03
5G covers under 40% of landmass. This Whitepaper details how 3GPP Release 17 addresses six satellite challenges: delay, Doppler, path loss, polarization, spectrum, and architecture.What Attendees will LearnWhy non-terrestrial networks are now integral to the 5G roadmap — Understand how the Third Generation Partnership Project (3GPP) Release 17 incorporates satellite-based connectivity into the 5G system, targeting ubiquitous coverage across maritime, remote, and polar regions where terrestrial networks reach less than 40% of the world’s landmass. Learn the distinction between New Radio non-terrestrial networks for mobile broadband and Internet of Things non-terrestrial networks for low-power machine-type communications.How satellite constellation design shapes coverage, capacity, and latency — Examine how orbit altitude (low earth orbit, medium earth orbit, geostationary earth orbit), beam footprint geometry, elevation angle, and inclination determine coverage area, round-trip time, and differential delay across user equipment within a single beam. Explore the trade-offs between transparent bent-pipe and regenerative onboard-processing payload architectures.What radio frequency challenges distinguish satellite links from terrestrial propagation — Explore the six major technical challenges: high free-space path loss, time-variant Doppler, differential delay across large beam footprints, Faraday rotation of polarization through the ionosphere, and spectrum coexistence between terrestrial and non-terrestrial bands in the S-band and L-band.How 5G protocols must adapt to support non-terrestrial connectivity — Learn the specific amendments to hybrid automatic repeat request operation, timing advance control (split into common and user-equipment-specific components), random access procedure timing extensions, discontinuous reception power saving adaptations, earth-fixed tracking area management, conditional handover mechanisms, and feeder link switching for service continuity in a unique propagation environment.Download this free whitepaper now!

What you will learn about:
- How 3GPP Release 17 introduces non-terrestrial network support into the 5G system through two complementary paths: New Radio non-terrestrial networks for mobile broadband services and Internet of Things non-terrestrial networks for low-power machine-type communications.
- How satellite orbit selection — low earth orbit, medium earth orbit, or geostationary earth orbit — determines coverage geometry, round-trip, beam footprint size, and differential delay across user equipment, and why these parameters drive every subsequent design decision
- How the transparent bent-pipe architecture disaggregates the base station into satellite, ground gateway, and terrestrial baseband functions
- How radio frequency challenges unique to satellite links — free-space path loss, time-variant Doppler shift, ionospheric Faraday rotation of polarization, and spectrum coexistence between overlapping terrestrial and non-terrestrial bands — require new compensation strategies at both the device and network level
- How 5G medium access control and radio resource control procedures are amended to function over satellite links, timing advance split into common and user-equipment-specific components, random access window deferral, earth-fixed tracking area management, conditional handover triggers based on distance or timing rather than received power, and discontinuous reception timer adaptations for power saving

More Information
Wireless communications technologies today reach more than 80% of the world’s population — yet cover less than 40% of its landmass. 3GPP Release 17 addresses this gap by bringing satellite-based connectivity into the 5G system with minimal changes to existing specifications. This whitepaper follows the complete technology chain. It begins with International Telecommunication Union spectrum coordination in the S-band and Ka-band, moves through satellite constellation physics and link budget analysis, and concludes with the protocol-layer.
