1. A method for wireless power transmission, the method comprising:

  • determining, by a transmitter, one or more transmission parameters for transmitting chirp power waves to a wireless power receiver located within a transmission field of the transmitter, the one or more transmission parameters based upon mapping data and sensor data, wherein;

    the mapping data and sensor data indicates respective locations of one or more objects and receivers within the transmission field of the transmitter, andthe transmitter comprises a first set of antennas and a second set of antennas;

    determining, by the transmitter, first characteristics to use for generating a first waveform and second characteristics to use for generating a second waveform, the first and second characteristics corresponding to the one or more transmission parameters, wherein the first and second characteristics include characteristics selected from a group consisting of an amplitude and a frequency;

    generating, by a waveform generator of the transmitter;

    the first waveform having the first characteristics, and the second waveform having the second characteristics;

    transmitting, by the first set of antennas of the transmitter and to the wireless power receiver, first chirp power waves using the generated first waveform;

    transmitting, by the second set of antennas of the transmitter and to the wireless power receiver, second chirp power waves using the generated second waveform; and

    adjusting, by the waveform generator of the transmitter, the first and second waveforms based on one or more updates to the one or more transmission parameters.
