Telemetry architecture for long-distance pipelines: RTUs at compressor stations, LTE/Mesh communications to central SCADA, and automatic failover on link failure. Applied to Peru's natural gas transport system.
Long-distance pipeline telemetry faces three challenges: extreme terrain (Andean crossings at 4,600m), absence of cellular coverage for hundreds of kilometers, and the need for sub-30-second valve actuation response in emergencies.
The architecture layers three technologies: Robustel R5000 industrial LTE routers as primary RTU gateways (dual-SIM, −40°C rated, built-in VPN), Rajant BreadCrumb 900MHz for backhaul in LTE-dead zones (15-20km per hop at 3-8 Mbps), and Inductive Automation Ignition SCADA in Lima with OT-IT segmentation per NIST CSF. After 24 months in a 550km Cusco-Ayacucho pipeline: 99.92% telemetry availability, 19s average remote valve closure time.
Technical guide for designing telemetry and remote SCADA networks using Robustel industrial LTE routers. Applications in north coast oil & gas, hydroelectric plants, and rural electrical substations in the Peruvian context.
