NTN X-Haul: Fronthaul, Midhaul et Backhaul par Satellite pour Réseaux 5G et 6G

NTNXhaul analyse l'architecture de transport cellulaire sur constellations satellites à très haut débit, évaluant les découpages fonctionnels O-RAN (Split 7.2x vs Split 2), l'agrégation de bande passante et les SLA opérateur.

NTNXhaul System Architecture

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)
