National Railway keeps rolling with private to public cellular wireless roaming
5 PagesA US‑based Class 1 freight railroad operator across 22 states struggled with spotty public‑carrier 4G coverage that disrupted operations and delayed train certification in rail yards. Celona’s 4G private wireless software created a deterministic, secure LAN that seamlessly roams with the operator’s dual‑SIM strategy, eliminating erratic connectivity between public and private networks.
