Design of Wireless Powered Communication Systems for Low-Altitude Economy

With the rapid development of the low-altitude economy, efficient energy supply and communication systems have become key demands for low-altitude vehicles and Internet of Things (IoT) devices. This study investigates wireless powered communication systems (WPCSs) for low-altitude economy, focusing on the energy consumption characteristics of different power supply schemes under various practical application scenarios. Through simulation experiments, we compared the energy efficiency of traditional battery power, simple wireless power supply, optimized wireless power supply, and the proposed efficient WPCS (with dynamic adjustment) under changes in transmission distance, communication frequency, weather conditions, flight speed, and task complexity. The results show that traditional battery power schemes exhibit high energy consumption in long-distance transmission and high-frequency communication scenarios, while the proposed efficient WPCS significantly reduces the rate of energy consumption increase through dynamic energy transmission adjustment mechanisms, demonstrating the lowest energy consumption levels across all test scenarios. This research provides important theoretical and practical references for the design of WPCS in the low-altitude economy, highlighting the significant advantages of dynamic adjustment mechanisms in improving energy efficiency and offering technical support for the sustainable development of the low-altitude economy.
