The method proposed in this paper examines the power supply to a terminal using electromagnetic waves for wireless power transfer. Packet transmissions used in communication are utilized in analyzing the power supply within the proposed method. Conversion of power into packets allows for traffic analysis, which is similar to conventional communication traffic analysis. Moreover, the power supply can manage charging capacity through queue control. Unlike signals used for traffic analysis, interference conditions can be transformed into power supply energy, making it easier to analyze than when using conventional methods. Consequently, in this study, we built a simulator that transforms power into packets and selected specific parameters.
