Innovation:   
  In order to increase the effective communication range, the research will extend from a single drone system to a multi-relay point (Multi-Hop) architecture. In addition, the research also applied the technology to Multi-Hop UAVs long-distance communication by using software-defined radio (SD R) to change its transmission protocol, frequency band, and modulation technology through software, so as to achieve dynamic perception and adaptive adjustment of interference.

The developed multi-hop UAV SDR communication system provides long-distance, low-latency, interference-resistant communication for critical missions. It ensures stable, real-time image streaming between UAVs using fr equency adaptation and frequency-division relays, powered by FPGA-based image processing. The system also features patented buoyancy-assisted stability control for enhanced endurance and aerodynamic collision avoidance to prevent UAV collisions, ensuring robust and safe operations.

This system uses multi-hop UAVs and SDR technology to establish aerial communication links in disaster/war zones without network infrastructure, transmitting high-definition imagery and supporting AI analysis for enhanced decision-making. Applied in earthquake, landslide rescue, and defense reconnaissance, it offers high scalability and flexibility. Aligned with 6G resilient communication trends, it strengthens Taiwan＇s disaster response and tech industry competitiveness.
