Abstract
A system and method for determining a microwave beam and a power setting for wireless power transfer within a volume with a beamforming antenna. The method includes determining a perimeter for the volume, and determining a transmit power threshold based on the perimeter. The method includes establishing a communication link with a mobile electronic device within the volume, and determining a position of the mobile electronic device. The method includes sensing whether a person is located within the volume, and, when a person is located within the volume, sensing a position of the person, determining a microwave beam based on the position of the mobile electronic device and the position of the person, and determining a power setting for the microwave beam based on the position of the mobile electronic device, the position of the person, the transmit power threshold, and a power density distribution for the microwave beam.
