Combined System of Wireless Power Transfer and Communication
This presentation will introduce systems combined Wireless Power Transfer (WPT) and communication systems and base stations towards beyond 5G and 6G. With the expansion of IoT business and digital transformation, the number of IoT sensor is expected to continually increase. In the era of beyond 5G and 6G, it becomes essential to provide both information and power wirelessly in order to reduce the effort and cost of battery replacement and wiring. We propose to perform WPT from a transmitter to IoT sensors by effectively utilizing the available resource blocks in communication systems and base stations. This system actively performs beamforming to the target according to TDD timing. This presentation will present experimental results verifying that the developed combined communication and WPT system can provide both data transmission to one target and power transmission to the other target.
