Embodiments disclosed herein may generate and transmit power waves that, as result of their physical waveform characteristics (e.g., frequency, amplitude, phase, gain, direction), converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers associated with an electronic device being powered by the wireless charging system, may extract energy from these pockets of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pockets of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy.

1. A method, comprising: at a transmitter with a processor, a wireless communications component, and a plurality of antennas separate and distinct from the wireless communications component: transmitting, via the plurality of antennas, one or more power waves into a transmission field of the transmitter;receiving, via the wireless communications component, feedback data from a wireless power receiver indicating receipt of at least some of the one or more power waves at an initial location within the transmission field of the transmitter;detecting movement of the wireless power receiver away from the initial location;in response to detecting the movement of the wireless power receiver away from the initial location, determining, by the processor, (i) a predicted location of the wireless power receiver and (ii) a time at which the wireless power receiver is estimated to reach the predicted location based on the movement of the wireless power receiver away from the initial location; andtransmitting, via the plurality of antennas and at the determined time, higher power level power waves that converge and constructively interfere at the predicted location of the wireless power receiver. 2. The method of claim 1, wherein the predicted location of the wireless power receiver and the time are determined based on a speed of the wireless power receiver as it moves away from the initial location. 3. The method of claim 1, wherein the higher power level power waves is transmitted in advance of the wireless power receiver's arrival at the predicted location. 4. The method of claim 1, wherein the one or more power waves are exploratory power waves used to identify the wireless power receiver, and the exploratory power waves have a lower power level as compared to the higher power level power waves. 5. The method of claim 1, wherein detecting the movement of the wireless power receiver away from the initial location includes: receiving information from the wireless power receiver, via the wireless communication component, that indicates the movement of the wireless power receiver. 6. The method of claim 1, wherein detecting the movement of the wireless power receiver away from the initial location includes: receiving information from a sensor associated with the transmitter that indicates the movement of the wireless power receiver. 7. The method of claim 6, wherein the sensor associated with the transmitter is at least partially housed within the transmitter. 8. The method of claim 6, wherein the sensor is external to the transmitter. 9. The method of claim 1, further comprising: before the detecting, transmitting an initial set of higher power level power waves that converge and constructively interfere at the initial location of the wireless power receiver; andafter the detecting, ceasing to transmit the initial set of higher power level power waves. 10. A transmitter, comprising: a plurality of antennas configured to transmit one or more power waves into a transmission field of the transmitter,a wireless communications component separate and distinct from the plurality of antennas configured to receive feedback data from a wireless power receiver indicating receipt of at least some of the one or more power waves at an initial location within the transmission field of the transmitter; anda processor configured to: detect movement of the wireless power receiver away from the initial location;in response to detecting the movement of the wireless power receiver away from the initial location, determine (i) a predicted location of the wireless power receiver and (ii) a time at which the wireless power receiver is estimated to reach the predicted location based on the movement of the wireless power receiver away from the initial location; andcause transmission, via the plurality of antennas and at the determined time, higher power level power waves that converge and constructively interfere at the predicted location of the wireless power receiver. 11. The transmitter of claim 10, wherein the predicted location of the wireless power receiver and the time are determined based on a speed of the wireless power receiver as it moves away from the initial location. 12. The transmitter of claim 10, wherein the higher power level power waves is transmitted in advance of the wireless power receiver's arrival at the predicted location. 13. The transmitter of claim 10, wherein the one or more power waves are exploratory power waves used to identify the wireless power receiver, and the exploratory power waves have a lower power level as compared to the higher power level power waves. 14. The transmitter of claim 10, wherein detecting the movement of the wireless power receiver away from the initial location includes: receiving information from the wireless power receiver, via the wireless communication component, that indicates the movement of the wireless power receiver. 15. The transmitter of claim 10, wherein detecting the movement of the wireless power receiver away from the initial location includes: receiving information from a sensor associated with the transmitter that indicates the movement of the wireless power receiver. 16. The transmitter of claim 15, wherein the sensor associated with the transmitter is at least partially housed within the transmitter. 17. The transmitter of claim 15, wherein the sensor is external to the transmitter. 18. The transmitter of claim 10, wherein the processor is further configured to: before the detecting, cause transmission of an initial set of higher power level power waves that converge and constructively interfere at the initial location of the wireless power receiver; andafter the detecting, cause ceasing to transmit the initial set of higher power level power waves. 19. A non-transitory, computer readable storage medium storing one or more programs, the one or more programs comprising instructions that, when executed by a transmitter with a processor, a wireless communications component, and a plurality of antennas separate and distinct from the wireless communications component, cause the transmitter to: transmit one or more power waves into a transmission field of the transmitter;receive feedback data from a wireless power receiver indicating receipt of at least some of the one or more power waves at an initial location within the transmission field of the transmitter;detect movement of the wireless power receiver away from the initial location;in response to detecting the movement of the wireless power receiver away from the initial location, determine (i) a predicted location of the wireless power receiver and (ii) a time at which the wireless power receiver is estimated to reach the predicted location based on the movement of the wireless power receiver away from the initial location; andtransmit, via the plurality of antennas and at the determined time, higher power level power waves that converge and constructively interfere at the predicted location of the wireless power receiver.
