These technologies have become increasingly relevant as advancements in drones, air mobility, telecommunications, and environmental monitoring create opportunities for economic growth in this airspace.
[0003] 5G-A (5G-Advanced) is an evolution and enhanced version of the 5G network. It has achieved significant improvements in network speed, latency, number of connections, etc., and has introduced new revolutionary technologies such as interawareness, passive IoT , and artificial intelligence. The system aims to use the 5G-A network to build a networked unmanned aerial vehicle (UAV) or drone system to achieve efficient, safe, and reliable operation of drones in the low-altitude economy , thereby promoting the vigorous development of the low-altitude economy. The solution includes key components such as networked terminals (drones) , 5G-A wireless networks, 5G-A core networks, 5G-A+ high-precision positioning , and drone management and operation platforms .
[0004] The 5G-A is featured by an enhanced mobile broadband (eMBB) , extended support for Internet of Things (IoT) , reduced latency, improved energy efficiency, new use cases and network slicing enhancements. The enhanced mobile broadband (eMBB) provides faster data speeds with peak rates expected to exceed 10 Gbps and improved coverage and capacity in dense urban and rural areas. The extended support for Internet of Things (IoT) provides massive Machine-Type Communications (mMTC) enhancements and support for extremely low-power, long-range devices (e.g., smart sensors) . The 5G-A can provide Ultra-Reliable Low Latency Communication (URLLC) refinements, with latencies dropping to less than 1 ms in some cases. The 5G-A can provide better resource utilization to reduce network energy consumption and focuses on sustainability for connected devices. New usages may include integration of AI and machine learning for dynamic network optimization, enhanced support for industrial applications, such as smart factories and autonomous vehicles and immersive experiences like AR / VR and holographic communications.
