Reti Non Terrestri 3GPP: Infrastruttura Spazio-Terra Unificata in 5G e 6G

NonTerrestrialNetwork definisce lo standard ingegneristico per le telecomunicazioni non terrestri unificate 3GPP. Coprendo IoT-NTN Rel-17, NR-NTN Rel-18, compensazione Doppler basata su effemeridi, calcolo del timing advance e nodi orbitali gNodeB trasparenti vs rigenerativi, questa piattaforma offre schemi architetturali di livello industriale per la convergenza spazio-terra.

Central System: 3GPP NTN Core - Space-Ground System

Network Nodes

  • NR-NTN S-Band
  • Direct-to-Cell
  • LEO gNodeB
  • Optical ISL
  • Q/V Feeder

Architectural Protocol Layers

  • User & Terminal Access Layer (3GPP Rel-17/18 NR-NTN & IoT-NTN): Direct communication from smartphones and IoT sensors to satellites
  • Space-Borne Radio Access (gNodeB / Transponder) (Regenerative Digital Payloads & Bent-Pipe Transparent Processing): In-orbit demodulation, digital beamforming, and spectrum channelization
  • Inter-Satellite Mesh & Space Transport (Optical Inter-Satellite Links (OISL) & 60 GHz V-Band Cross-Links): Autonomous multi-hop laser packet routing in vacuum at the speed of light
  • Ground Teleport & Core Cloud Ingress (High-Throughput Q/V-Band Gateways & Optical Ground Stations): Terabit feeder link downlinks connected directly to cloud hyperscalers

Key Metrics: 100 Gbps+ (Optical Cross-Link Bandwidth) | <25 ms (LEO Propagation Latency) | ±50 kHz (Doppler Shift Compensation) | 99.999% (Constellation Transport SLA)
