1. A transmitter device for wireless power transmission, the transmitter comprising:

  • a plurality of antennas configured to transmit power waves, wherein at least one antenna is a communications antenna configured to transmit and receive communication signals using a wireless communications protocol;

    a communication circuit coupled to the communications antenna and configured to receive communication signals representing status information from a receiver associated with an electronic device, wherein the status information includes a location of the receiver;

    an integrated circuit connected to the antennas and configured to generate the power waves and to adjust a phase and a gain of each respective power wave; and

    a microprocessor configured to control the integrated circuit configured to generate and adjust the phase and the gain of the power waves to form one or more pockets of energy at the location of the receiver resulting from a constructive interference pattern produced by converging the power waves at the location, and configured to control the communication circuit transmitting and receiving the communication signals containing the status information,whereby the transmitter is configured to wirelessly transmit the power waves to converge at a location associated with the receiver to form pockets of energy for capturing by the receiver, and whereby the transmitter is configured to adjust the phase and the gain of the power waves to converge at a location associated with the receiver to form pockets of energy for reception by the receiver.
