  • receiving, by a transmitter, a communication of a power requirement of an electronic device and a location of a receiver associated to the electronic device;

    upon recognition of the location as an authorized location of the receiver, generating, by the transmitter, power transmission waves that converge to form a pocket of energy;

    controlling, by the transmitter, generated power transmission waves to provide phase shifting and gain shifting with respect to other power transmission waves;

    transmitting, by the transmitter, the power transmission waves through at least two antennas coupled to the transmitter; and
