$GTCHD The system communicates through an ionospheric propagation environment, one reaching very long distances. The patent covers an AI system and method to overcome any major long-range radio challenges, which communicate through skip zones where there is no reception. The proposed dead-zone coverage solution is based on AI geo-referenced analytics and management to enable continuous, reliable communications regardless of terrain, time of day or year, and other weather-related conditions.
