5G covers below 40% of landmass. This Whitepaper particulars how 3GPP Launch 17 addresses six satellite tv for pc challenges: delay, Doppler, path loss, polarization, spectrum, and structure.
What Attendees will Study
- Why non-terrestrial networks at the moment are integral to the 5G roadmap — Perceive how the Third Technology Partnership Challenge (3GPP) Launch 17 incorporates satellite-based connectivity into the 5G system, concentrating on ubiquitous protection throughout maritime, distant, and polar areas the place terrestrial networks attain lower than 40% of the world’s landmass. Study the excellence between New Radio non-terrestrial networks for cell broadband and Web of Issues non-terrestrial networks for low-power machine-type communications.
- How satellite tv for pc constellation design shapes protection, capability, and latency — Look at how orbit altitude (low earth orbit, medium earth orbit, geostationary earth orbit), beam footprint geometry, elevation angle, and inclination decide protection space, round-trip time, and differential delay throughout person tools inside a single beam. Discover the trade-offs between clear bent-pipe and regenerative onboard-processing payload architectures.
- What radio frequency challenges distinguish satellite tv for pc hyperlinks from terrestrial propagation — Discover the six main technical challenges: excessive free-space path loss, time-variant Doppler, differential delay throughout giant beam footprints, Faraday rotation of polarization by the ionosphere, and spectrum coexistence between terrestrial and non-terrestrial bands within the S-band and L-band.
- How 5G protocols should adapt to assist non-terrestrial connectivity — Study the particular amendments to hybrid automated repeat request operation, timing advance management (cut up into widespread and user-equipment-specific elements), random entry process timing extensions, discontinuous reception energy saving variations, earth-fixed monitoring space administration, conditional handover mechanisms, and feeder hyperlink switching for service continuity in a singular propagation surroundings.
