1. A method for transmitting wireless power comprising:

  • receiving, by a transmitter from at least one of a plurality of antennas, a first communication signal from a receiver coupled to an electronic device, the first communication signal comprising a location and device parameters associated with the electronic device;

    splitting, by the transmitter, the plurality of antennas into at least one communication antenna and a first group of antennas;

    assigning, by the transmitter, the first group of antennas to the receiver based on the device parameters associated with the electronic device;

    transmitting, by the transmitter, two or more power transmission waves from the first group of antennas such that the power transmission waves converge as constructive interference patterns to form a pocket of energy at the location associated with the electronic device;

    receiving, by the transmitter via the at least one communication antenna, a second communication signal from the receiver, the second communication signal comprising a power level associated with the electronic device;

    adjusting, by the transmitter, a phase at which power transmission waves are transmitted by each antenna of the first group of antennas based on the power level associated with the electronic device; and

    transmitting, by the transmitter, two or more power transmission waves having the adjusted phase from the first group of antennas such that the power transmission waves converge as constructive interference patterns to form an adjusted pocket of energy at the location associated with the electronic device.
