ROI Calculation Logic

By enabling both fixed and mobile reception services on a single broadcast wave, this technology could reduce redundant equipment investments and frequency license fees. For example, if two services each incur ~$1M (AI est.) annually in frequency license and operational maintenance fees, this technology could reduce these costs by approximately 50%, resulting in an estimated annual saving of ~$1M (AI est.) per service. Including further savings from reduced retransmission and complaint handling due to lower adjacent channel interference, total annual cost reductions could exceed ~$2M (AI est.).

Speed to Market
5× faster than in-house development
This technology specifically discloses algorithms and configurations for the core components of modulation devices and receivers, establishing a strong technical foundation. Developing equivalent interference suppression and multiplexing technology from scratch in-house could take approximately 4.0 years from conceptual design to validation and patent acquisition. However, by licensing this patent, companies can leverage established, patented technical knowledge, potentially shortening the development period to around 0.8 years. This enables faster market entry and the capture of first-mover advantages.
