ROI Calculation Logic

This technology is estimated to reduce signal error rates in transmission paths by approximately 30% compared to conventional methods. This could decrease the frequency of error correction processing and retransmissions, lightening the processing load on transmission systems and potentially reducing annual power consumption by about 15%. For a system with an annual electricity cost of $650K (AI est.), this could lead to an annual operational cost reduction of $100K (AI est.). Including reduced maintenance due to high reliability, the total economic impact is estimated to be several hundred thousand dollars annually (AI est.).
