This Whitepaper details how 3GPP Release 17 addresses six satellite challenges: delay, Doppler, path loss, polarization, spectrum, and architecture.\n\n**What Attendees will Learn**\n\n  1. Why 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.\n  2. 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.\n  3. 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.\n  4. 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.\n\n\n\nDownload this free whitepaper now!",
