This study assesses telecommunications infrastructure and traffic engineering in Raja Ampat, Indonesia, comprising four main islands and over 1,500 smaller islands across 46,000 km² of marine protected area. Field measurements at 48 points over 2023–2024, combined with QoS evaluation and SWOT-based assessment, revealed adequate signal coverage (–65 to –80 dBm) only within 1 km of shore-based stations, degrading to –95 to –110 dBm at offshore diving locations (5–15 km), where throughput dropped to 2–5 Mbps against the 10–50 Mbps requirement. A Modified Erlang B Model showed 3–4× seasonal traffic variation, with peak busy-hour demand reaching 2.5–4 Gbps from 300–560 concurrent users and the Misool–Salawati backhaul reaching 95% utilization. Capacity forecasting (R² = 0.91) indicates saturation within 2–3 years. An integrated approach combining additional base stations, expanded backhaul, LEO satellite integration, and renewable energy is essential.
