Integration Roadmap — Estimated 16-Month Deployment
Phase 1: Technical Validation & Requirements Definition
Duration: 2 months
Evaluate the compatibility of the core algorithm with existing systems and define specific functions and system design based on licensee requirements.
Phase 2: Prototype Development & PoC
Duration: 6 months
Proceed with prototype implementation into internet radio receivers or IoT devices based on the design, conducting performance evaluation and Proof of Concept (PoC) in limited environments.
Phase 3: Production System Deployment & Rollout
Duration: 8 months
Integrate PoC results, deploy the system into the production environment, link relevant databases, and conduct extensive operational testing before full market rollout.
Technical Feasibility
This technology can leverage existing broadcast receiving antennas and demodulators, with core functions implemented through software and database integration. Therefore, licensees would not require extensive hardware modifications, enabling integration into existing internet radio receivers or IoT devices via relatively low-cost software updates or module additions. High compatibility with general communication protocols is expected to reduce development burden and enable rapid deployment.
