Abstract

To provide an electronic apparatus capable of stably and efficiently acquiring electric power, and a control method of the electronic apparatus.SOLUTION: An electronic apparatus includes an antenna, and conversion means for converting radio waves received through the antenna into electric power. The electronic apparatus selects one or more channels from a plurality of channels based on electric power detected for each of the plurality of channels that can be used for communication with an external apparatus with which it can communicate through the antenna. The electronic apparatus then transmits a channel setting request including information about the selected one or more channels to the external apparatus.SELECTED DRAWING: Figure 3
