1. A method for wireless powering of an electronic device, comprising:

  • receiving, by a transmitter, an activation command via an activation button associated with the transmitter that causes the transmitter to create a first constructive interference pattern by converging a first plurality of radio frequency (RF) power transmission waves near a surface of the transmitter to power an electronic device that has insufficient power to communicate with the transmitter;

    transmitting, by the transmitter, the first plurality of RF power transmission waves to converge to form the first constructive interference pattern near the surface of the transmitter; and

    after the electronic device has sufficient power to communicate with the transmitter;

    receiving, from the electronic device, an indication of a location of the electronic device; and

    transmitting a second plurality of RF power transmission waves that converge to form a second constructive interference pattern, distinct from the first constructive interference pattern, near the location of the electronic device.
