ROI Calculation Logic

Assuming an average annual operational cost of $350K (AI est.) per site for time synchronization systems in wide-area networks (including maintenance, power, and dedicated line costs). If this technology enables a 50% operational efficiency improvement by integrating systems across 5 sites and reducing errors due to enhanced precision, the estimated reduction is 5 sites × $350K/site × 50% = $850K (AI est.) annually. Considering additional reduction in opportunity loss from higher precision, the total economic benefit could exceed $1.5M (AI est.) annually.
