No more device batteries? Researchers at Georgia Institute of Technology’s ATHENA lab discuss an innovative way to tap into the over-capacity of 5G networks, turning them into “a wireless power grid” for powering Internet of Things (IoT) devices. The breakthrough leverages a Rotman lens-based rectifying antenna capable of millimeter-wave harvesting at 28 GHz. The innovation could help eliminate the world’s reliance on batteries for charging devices by providing an alternative using excess 5G capacity.
