Abstract
According to one embodiment, an electronic apparatus for feeding power to an electronic device by an electromagnetic wave in a first frequency band, includes a receiver and a transmitter. The receiver receives a beacon from the electronic device via at least a part of the first frequency band. The beacon includes an unmodulated signal at least partly. The transmitter transmits a first electromagnetic wave for feeding power to the electronic device via the first frequency band based on the beacon. A time length of the beacon is different from a time length of the first electromagnetic wave.
