THE OPERATIONAL REALITY
Four Connectivity Crises Costing You Millions Per Incident
🔥 ATEX Zone Communication Void
Standard industrial WiFi cannot be deployed in IEC 60079 Zone 1/2 hazardous areas. Operators in compressor stations, flare zones, and wellhead areas rely on wired comms or exit the zone to radio in — creating dangerous, costly communication delays during critical operations.
↳ HCT: ATEX Zone 1/2 certified 5G devices. Intrinsically safe handsets with guaranteed connectivity throughout the hazardous perimeter.
🌊 Offshore Platform Isolation
Offshore rigs in the Arabian Gulf sit 50–200km from shore — beyond all terrestrial coverage. Legacy VSAT delivers 1–5 Mbps shared across 200 workers. Real-time SCADA, remote expert video support, and HSE video surveillance are impossible on bandwidth-starved satellite links.
↳ HCT: Platform-mounted private LTE with microwave backhaul to shore + VSAT failover. 100+ Mbps dedicated per platform.
🔌 SCADA on Public Networks
ICS/SCADA systems managing valves, pumps, and compressors along pipeline corridors are increasingly routed through commercial carrier networks — creating cybersecurity attack surfaces. A latency spike of 100ms on a valve control signal can trigger a cascade failure across the pipeline system.
↳ HCT: Dedicated private LTE for SCADA with <5ms deterministic latency. Air-gapped from public internet. IEC 62443 compliant.
🚁 Remote Site Crew Connectivity
Pipeline inspection crews, wellsite geologists, and maintenance technicians in remote desert or mountain terrain operate with zero coverage. Real-time LiDAR inspection data, drone feeds, and location tracking cannot be transmitted — creating HSE compliance gaps and delayed decision-making.
↳ HCT: Band 28 700MHz for 20–40km cell radii in open terrain. Rapid-deploy masts for remote sites. Drone/UAV data offload.
