Redes No Terrestres 3GPP: Infraestructura Unificada Espacio-Tierra en 5G y 6G

NonTerrestrialNetwork define el estándar de ingeniería para telecomunicaciones no terrestres unificadas bajo 3GPP. Cubriendo IoT-NTN de Rel-17, NR-NTN de Rel-18, compensación Doppler asistida por efemérides, cálculo de timing advance y despliegues orbitales gNodeB transparentes vs regenerativos, esta plataforma proporciona la arquitectura definitiva para la convergencia espacio-tierra.

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)
