ROI Calculation Logic

This technology could improve MIMO communication modulation error rates by an average of 20%. This reduces data retransmission frequency and enhances network bandwidth utilization. For example, in widespread base station operations, it could reduce unnecessary power consumption and processing load from retransmissions by approximately 20% annually. For a communication infrastructure with annual operating costs of $1.5M (AI est.), this translates to an annual cost reduction of $0.2M (AI est.) (calculated as $1.5M × 20% × 0.75 for power/processing costs), plus an additional $0.8M (AI est.) in avoided equipment expansion costs due to improved bandwidth efficiency, totaling an estimated annual economic impact of $1.0M (AI est.).
