ROI Calculation Logic

For enterprises monitoring large areas, conventional methods required specialized operators for on-site surveys (5 operators × $55K/operator = $275K/year (AI est.)) and expensive scanning antenna systems ($650K/year (AI est.) for operation and maintenance). This technology could reduce these costs by half, saving ~$125K/year (AI est.) in personnel and ~$325K/year (AI est.) in system O&M, totaling ~$450K/year (AI est.) in direct operational savings. Additionally, by reducing communication disruption losses (up to ~$1.5M/year (AI est.)) by 20%, it could avoid ~$300K/year (AI est.) in losses. The total direct cost savings and avoided losses are estimated at ~$750K/year (AI est.). Furthermore, up to ~$950K/year (AI est.) in opportunity loss avoidance is projected, leading to a total potential economic benefit of ~$1.7M/year (AI est.).
