ROI Calculation Logic

In communication infrastructure maintenance, regular quality checks of base stations and repeaters are essential. This technology automates and enhances the precision of measurement tasks previously performed manually or with expensive specialized equipment. For example, if monthly 5-hour inspection work at 100 locations can be reduced by 50% using this technology, assuming a worker cost of $20/hour (AI est.), the annual savings would be 100 locations × 5 hours/month × 12 months × ($20/hour) × 50% = $60,000 (AI est.). Combined with reduced opportunity loss from communication failures, the total estimated annual savings could reach ~$500K (AI est.).
