We introduce the world's first hybrid radio platform which combines the strengths of active radio (long range and robustness to interference) and Computational RFID (CRFID) (low power consumption). By a set of laboratory experiments, we show that our hybrid radio - composed of Wi ...
With the rapid development of mobile technology, more and more devices connect to the Internet of Things (IoT). The management of such large-scale networks becomes a challenge. Firstly, a large number of heterogeneous devices are distributed over a wide area, leading to a variati ...
RF-based WPTNs are deployed to transfer power to embedded devices over the air via radio requency waves. Up until now, a considerable amount of effort has been devoted by researchers to design WPTNs that maximize several objectives such as harvested power, energy outage, and char ...

wireless power transfer network (WPTN) aims to support devices with cable-less energy on-demand. Unfortunately, wireless power transfer itself-especially through radio frequency radiation rectification-is fairly inefficient due to decaying power with distance, antenna polariza ...
