1. A system in a wireless power delivery network, comprising:

  • a plurality of transmitter managers, each comprising a database storing records associated with a plurality of user devices; and

    a plurality of power transmitters communicatively coupled to (i) the plurality of transmitter managers and (ii) a power receiver coupled with a respective user device of the plurality of user devices;

    wherein at least one power transmitter of the plurality of power transmitters is configured to transmit signals received from the power receiver to at least two transmitter managers of the plurality of transmitter managers;

    wherein a respective transmitter manager of the at least two transmitter managers is configured to, based on (i) the signals received from the power receiver and (ii) the records stored in respective databases of the at least two transmitter managers, determine whether the respective transmitter manager has control over the respective user device; and

    in accordance with a determination that only one of the at least two transmitter managers has control over the respective user device, then the only one of the at least two transmitter managers is configured to instruct at least one of the plurality of power transmitters to transmit a plurality of power transmission signals that converge to generate a constructive interference pattern in proximity to the power receiver; and

    in accordance with a determination that the at least two transmitter managers of the plurality of transmitter managers have control over the respective user device, then each of the at least two transmitter managers is configured to instruct at least one of the plurality of power transmitters to transmit power transmission signals to the power receiver according to time division multiplexing (TDM) of communications between the power receiver and each of the at least two transmitter managers.
