1. A method of wirelessly transmitting power waves at a far-field transmitter based on parameters received from a receiver, the method comprising:

  • before receiving any communications from any device within a transmission field of a far-field transmitter, transmitting, by the far-field transmitter that includes a plurality of antenna elements and a communications component, a plurality of exploratory power waves, including at least one exploratory power wave, towards different segments of the transmission field of the far-field transmitter, using at least one of the plurality of antenna elements;

    receiving, by the far-field transmitter and from a receiver, a communication signal via the communications component, the communication signal including one or more parameters;

    (i) identifying a first location of the receiver within a segment of the different segments at which the at least one exploratory power wave of the plurality of exploratory waves was received by the receiver within the transmission field associated with the transmitter and (ii) providing feedback to the far-field transmitter regarding the at least one exploratory power wave of the plurality of exploratory waves;

    upon receiving the one or more parameters;

    storing, by the transmitter, the one or more parameters into a mapping memory comprising non-transitory machine-readable storage media configured to store the one or more parameters;

    determining, based on the first location and the feedback from the receiver, a set of characteristics for a plurality of power waves;

    transmitting, by at least some of the plurality of antennas of the far-field transmitter, the plurality of power waves with the determined set of characteristics to the first location; and

    continuing to transmit exploratory waves while transmitting, by at least some of the plurality of antennas of the far-field transmitter, the plurality of power waves with the determined set of characteristics to the first location.
