As 5G technology and Low Earth Orbit (LEO) satellites revolutionize the wireless communication landscape, the need for accurate and comprehensive OTA (Over-The-Air) testing becomes critical. In this paper, we introduce a brand-new OTA measurement system specifically tailored to address the unique challenges posed by 5G and LEO satellite communications. The system encompasses a wide frequency range, adaptive beamforming capabilities, advanced multipath channel emulation, and dynamic moving platform simulation to ensure precise testing of wireless devices. Moreover, it includes features for evaluating digital data throughput in realistic conditions, accommodating the increasing demand for massive IoT device support. With a compact design and optimized procedures, this system significantly reduces measurement time while maintaining accuracy. This paper showcases the innovative features and advantages of our OTA measurement system, positioning it as a powerful tool for accelerating the development and deployment of cutting-edge 5G and LEO satellite technologies in today's connected world.
