WIRELESS COMMUNICATION DEVICE AND WIRELESS COMMUNICATION METHOD

A wireless communication device includes: a power storage element configured to store an electric power generated by a power generation element; and a processor configured to: calculate a power storage speed of the power storage element from a temporal change in a voltage of the power storage element; estimate a power generation amount of the power generation element based on a power consumption corresponding to a setting of wireless communication, and the power storage speed; and perform the setting of wireless communication according to the estimated power generation amount.
