ROI Calculation Logic

Assuming an IP broadcast service, improved retransmission efficiency could reduce server load by 20% and improve bandwidth utilization by 15%. For annual operational costs (servers, network, etc.) of ~$1.5M (AI est.), the cost reduction from efficiency gains is estimated at ~$1.5M × 20% = ~$350K/year (AI est.). Stabilized communication quality could also reduce customer churn, leading to indirect revenue growth.
