Exploring the Application of Remote Sensing Technology in 5G Millimeter-Wave Communication System Construction

5G millimeter-wave communication technology has emerged as a cornerstone of next-generation communication systems due to its high-speed and low-latency characteristics. However, its deployment faces challenges such as signal attenuation, coverage blind spots, and complex base station siting. This paper proposes an interdisciplinary solution by integrating remote sensing technology to address these issues. Through literature review and case analysis, the study focuses on the application of remote sensing in signal propagation modeling, base station optimization, and system monitoring and maintenance. The results demonstrate that remote sensing enables precise acquisition of terrain, building, and meteorological data, effectively supporting base station siting and mitigating signal obstruction. Additionally, case studies validate the adaptability of multi-source remote sensing data fusion in complex scenarios. A channel prediction algorithm and an integrated communication-sensing framework are proposed, offering novel insights for intelligent future communication systems. The research confirms that remote sensing technology significantly enhances the construction efficiency and stability of 5G millimeter-wave communication systems, underscoring its critical engineering value.
