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

  • receiving by a transmitter that includes a communications component, a plurality of antennas and a controller;

    via the communications component, a first control signal from a first electronic device coupled to a first receiver, the first control signal comprising information used to identify a location of the first electronic device, andvia the communications component, a second control signal from a second electronic device coupled to a second receiver, the second control signal comprising information used to identify a location of the second electronic device;

    assigning, by the controller of the transmitter, (i) a first group of the plurality of antennas of the transmitter to the first electronic device and (ii) a second group of the plurality of antennas to the second electronic device, wherein the first and second groups of antennas are distinct;

    determining, by the controller of the transmitter;

    a first effective waveform feature for transmitting power transmission signals to the first electronic device, anda second effective waveform feature for transmitting power transmission signals to the second electronic device; and

    transmitting;

    via the first group of the plurality of antennas, power transmission signals to the location of the first electronic device using the first effective waveform feature; and

    via the second group of the plurality of antennas, power transmission signals to the location of the second electronic device using the second effective waveform feature.
