1. A computer-implemented method comprising:

  • transmitting, by a transmitter device, into a transmission field associated with the transmitter device one or more first power waves and a first communications signal, the first communications signal containing a first set of transmission parameters defining one or more characteristics of the one or more first power waves;

    in response to the transmitter device receiving via a receiver communications signal from a receiver device, device data indicating a location of the receiver within a segment of the transmission field;

    transmitting, by the transmitter device, one or more second power waves and a second communications signal including a second set of transmission parameters into respective sub-segments within the segment of the transmission field in accordance with the device data, the second set of transmission parameters defining the one or more characteristics of the one or more second power waves;

    determining, by the transmitter device, one or more refined characteristics for one or more refined power waves defined by a set of refined parameters, wherein the set of refined parameters is determined based upon refined location data received from the receiver device indicating a refined location within a sub-segment;

    generating, by the transmitter device, the one or more refined power waves having the one or more refined characteristics, according to the set of refined parameters; and

    transmitting, by the transmitter, the one or more refined power waves into the sub-segment of the transmission field, thereby forming a pocket of energy at the refined location.
