ROI Calculation Logic

This technology significantly reduces costs associated with new data service deployment, such as avoiding interference with existing broadcasts and building dedicated infrastructure. For example, by circumventing new frequency band acquisition and large-scale capital investments, and assuming a ~10% reduction in annual operational costs, an economic benefit of ~$1.5M (AI est.) is projected, representing 10% of a broadcast operator's ~$15M (AI est.) annual related investments. This shortens service deployment lead times and prevents market entry opportunity losses.
