ROI Calculation Logic

Assuming a satellite broadcast service provider experiences an average annual loss of approximately 500 hours due to service interruptions or quality degradation from rain fade. If this technology reduces this loss by 30%, the economic benefit is estimated by: personnel costs for service recovery and customer support ($67/hour (AI est.) × 500 hours × 0.3 = $10,000 (AI est.)), plus lost revenue ($66.5M/year (AI est.) in satellite broadcast revenue × 1.5% service loss rate × 30% improvement = $300,000 (AI est.)), combined with associated infrastructure maintenance cost reductions (~$650,000/year (AI est.)), totaling approximately $960,000 (AI est.).
