Leveraging Movable-Element STARS for RSMA-SWIPT Under Practical System Imperfections
Moving wireless surfaces to charge devices and send data simultaneously
Researchers developed a wireless system that charges devices and transmits data at the same time using surfaces with movable elements that can change position. The system handles real-world complications like imperfect signal measurements and hardware defects, and delivers stronger performance than existing methods when tested across multiple configurations.
Wireless power transfer could reduce charging infrastructure costs and enable devices in remote or hard-to-reach locations to receive both data and power from a single system. The ability to move reflecting surfaces adds a new dimension for improving signal strength, which matters as wireless networks become denser and more devices compete for the same airspace.
