Why high fronthaul latency forces the Distributed Unit (DU) to stay on the ground while backhaul uses space.
Deploying o-ran splits over satellite in non-terrestrial environments requires solving fundamental physics constraints: path loss over 1000km distances, rapid carrier frequency shifts due to Doppler effects, and power-thermal limits of spaceborne hardware. The architecture provides deterministic mitigation strategies.
The protocol workflow for o-ran splits over satellite coordinates physical layer signal acquisition with higher-layer transport resilience. By leveraging open-loop ephemeris calculations and adaptive retransmission timers, communication links maintain uninterrupted throughput across satellite handoffs.
