Simultaneous Wireless Information and Power Transmission System Design for Sports Events

In this paper, we design a simultaneous wireless information and power transmission (SWIPT) system for sports events, which achieves efficient and cooperative transmission of information and energy through multi-layer architecture design and adaptive power separation algorithm. Measurements show that the system has an energy transmission efficiency of $27.8 \%$, a data transmission success rate of 97.3%, and a 380% increase in device endurance, which has been successfully applied in the National Basketball League Qualifier, providing a sustainable solution for the construction of intelligent stadiums. The system not only effectively solves the energy bottleneck problem of the traditional wireless system, but also significantly reduces the maintenance cost and improves the stability of technical support for events. In the future, SWIPT technology is expected to be widely promoted in more stadiums and smart city applications.
