Turangga Resources: Site-Wide Backbone Network Across Mining Clusters

Project Overview

Turangga Resources operates multiple coal mining clusters in South and Central Kalimantan — ABB, TOP, SMM, and PALA — spread across remote terrain. PT Natha Buana Indonesia was engaged to design and operate a site-wide backbone network connecting all clusters with high-capacity, highly reliable microwave radio links.

Network Architecture

The backbone is designed as a protected ring topology — each site has two independent paths back to the network core. If one link fails, traffic automatically reroutes through the alternate path, maintaining connectivity with no manual intervention.

• NBID POP Konut — primary point of presence for the ABB cluster
• NBID POP Hajak — secondary point of presence for the Pala cluster
• Tower Rinjani (ABB) — primary hub, 72m self-supporting tower
• Tower KM45 — mid-point relay, 90m SST
• Sekako (SMM) — ring endpoint with dual-path protection

Technology: Licensed Microwave Radio

• 500 Mbps capacity per link (Ceragon IP20C platform)
• 99% SLA availability commitment
• Licensed spectrum — low interference even in congested radio environments
• All-outdoor unit design for simplified installation and maintenance

Managed Service Commitments

• 24-month minimum service term with 99% availability SLA
• 30-minute Mean Time to Response (MTTR) from fault notification
• Dedicated on-site engineers at Buhut and Paring Lahung
• Monthly performance reports delivered by the 5th of the following month

Business Value

• Fleet Management System — real-time truck and heavy equipment tracking
• Safety monitoring and emergency communications
• Pit-to-Port logistics coordination
• Video surveillance of critical areas
• ERP and MIS data synchronization between site and head office
