Robustel Industrial Connectivity: LTE Routers for SCADA, Oil & Gas, and Energy

The connectivity challenge in dispersed infrastructure

Peruvian energy, hydrocarbon, and mining companies operate critical assets in remote locations where fiber is inaccessible and private microwave networks are prohibitively expensive for low-density sites. Oil wells on the north coast, small hydroelectric plants in Andean valleys, rural distribution substations in the highlands and jungle — all share the same problem: they need to send SCADA telemetry to the control center but lack fixed communications infrastructure.

The standard market solution has been the industrial LTE router: a rugged device using the commercial cellular network as SCADA backhaul, eliminating dependence on dedicated infrastructure.

Robustel product family for SCADA

R3000 LTE — standard SCADA gateway with dual SIM failover, RS-232/485 for legacy RTUs, VPN support (IPsec/OpenVPN/WireGuard), and -40°C to +70°C operating range. R2000 — dual connectivity (LTE + Ethernet WAN) for critical sites requiring fiber primary with LTE fallback in < 2 seconds. R5020 5G — for greenfield mining/O&G with 5G availability requiring < 20ms latency for remote machine control.

Key applications in Peru

North coast oil wells (Talara) with legacy RS-485 RTUs, Andean small hydroelectric plants (1-20 MW) transmitting COES-SINAC telemetry, and jungle pipeline pumping stations requiring remote monitoring. EMAR SYSTEMS provides configuration templates for Ignition, Wonderware, KEPServerEX, and Node-RED SCADA stacks.
