ROI Calculation Logic

Assuming a factory with 500 industrial IoT devices experiences 2 hours of communication error downtime per month, resulting in a loss of $1.7K/hour (AI est.). If this technology reduces downtime by 50%, the annual loss reduction is calculated as (2 hours/month × 12 months × $1.7K/hour (AI est.)) × 50% = ~$20.5K/year (AI est.). This calculation does not include productivity gains from improved communication quality.
