NTNCommunications: Comunicazioni Non Terrestri Unificate e Convergenza 5G/6G

NTNCommunications standardizza il framework di protocolli per integrare satelliti LEO, MEO, GEO e HAPS nelle reti 3GPP.

NTNCommunications 3D Heterogeneous Non-Terrestrial Network Topology

Harmonized control plane unifying terrestrial cellular with multi-orbit constellations

Central System: Terrestrial Sub-6GHz / mmWave RAN - High-density urban microcells and regional macro towers

Network Nodes

Terrestrial Sub-6GHz / mmWave RAN
Stratospheric HAPS Layer (20 km)
Dense LEO Constellation (600 km)
Unified 3GPP Rel-18/19 Core Network

Architectural Protocol Layers

Spaceborne PHY/MAC Layer (3GPP Rel-17 TS 38.300): Doppler compensation, HARQ disabling, and timing advance extension.
Orbital Mesh Routing (CCSDS / Delay-Tolerant Networking): Dynamic topology routing over intermittent laser crosslinks.
Regenerative Core Processing (OpenRAN / 3GPP CU-DU Split): Onboard user plane function (UPF) local breakout.

Key Metrics: < 18ms (LEO Orbit-to-Ground Roundtrip) | 100 Gbps (Optical Crosslink Throughput) | ±48 kHz (Doppler Shift Compensation) | 99.999% (Orbital Constellation Availability)
