WSR: Integrating Wireless Power Transfer with Communication Systems: Techniques and Strategies

Presentation Abstract
With the widespread use of mobile phones and smartphones, the contract for communication lines has shifted from being household-based to device-based. The wireless and mobile transformation of communication lines has improved communication speed and convenience, bringing significant changes to our society. However, electricity contracts remain at the household level and are limited to wired supply. The advancement of social implementation, such as DX (Digital Transformation), is predicted to significantly increase the number of sensors and IoT devices. In recent years, the development of 5G (fifth-generation mobile communication system) has aimed to establish a communication infrastructure capable of managing high volumes of traffic. However, significant challenges still persist regarding power supply methods for devices. To build a communication infrastructure capable of accommodating the increasing number of devices, wireless power supply methods to simplify battery replacement and charging are essential. This workshop focuses on research and development projects related to the integration of communication and power transmission. The requirements for research on the fusion of communication and power transmission include additive methods for incorporating wireless power transmission functionality into communication systems, power supply systems for communication purposes, mechanisms for simultaneous communication and power reception, device development for efficient conversion of radio waves into electrical energy, and the development of high-efficiency and cost-effective high-gain antennas. Wireless power transmission has recently been institutionalized in Japan and has begun commercial use. In the future, this theme will be of great importance in collaboration with Beyond-5G and 6G. The technologies presented in this session have the potential to significantly transform our energy utilization practices.
