1. A method for charging a mobile device, the method comprising:

  • at a transmitter device that includes (i) a communication component, (ii) at least two antenna elements, wherein the at least two antenna elements are distinct from the communication component, and (iii) a processor coupled to the communication component and the at least two antenna elements;

    receiving, by the communication component, a communication signal from a respective mobile device of a plurality of mobile devices when a level of power available to the respective mobile device falls below a predetermined level, wherein the communication signal from the respective mobile device includes data used to determine a location of the respective mobile device, the level of power available to the respective mobile device, and a history of power consumption of the respective mobile device; and

    ,in response to receiving the communication signal from the respective mobile device;

    determining (i) a location to form a pocket of energy and (ii) a time at which to form the pocket of energy based at least in part on the level of power available to the respective mobile device and on the history of power consumption of the respective mobile device, wherein;

    the location to form the pocket of energy is determined using the data received from the respective mobile device, andthe time is also determined relative to other scheduled times at which respective pockets of energy are to be formed for other mobile devices of the plurality of mobile devices; and

    at the determined time, transmitting, by the transmitter, a plurality of power transmission waves through the at least two antenna elements, wherein the plurality of power transmission waves converge in three-dimensional space near the determined location to form the pocket of energy for charging the respective mobile device.
