1. A system for wireless power delivery, the system comprising:

  • at least one transmitter manager; and

    a plurality of power transmitters communicatively coupled to (i) the at least one transmitter manager and (ii)a power receiver communicatively coupled to a user device,wherein a respective power transmitter of the plurality of power transmitters;

    is configured to transmit to the at least one transmitter manager signals received by the respective power transmitter from the power receiver andhas a respective power transfer range that defines a distance at which the respective power transmitter is able to wirelessly transmit power;

    wherein the at least one transmitter manager is configured to;

    (i) based on the signals received by the respective power transmitter from the power receiver, determine one or more power transmitters with respective power transfer ranges that cover a location of the power receiver;

    (ii) determine a master transmitter and at least one secondary transmitter in the determined one or more power transmitters for transmitting power transmission signals to the power receiver so as to charge or power the user device;

    wherein the master transmitter is different from the at least one secondary transmitter,the master transmitter is configured to (i) notify the at least one secondary transmitter that it is authorized to transmit the power transmission signals to the power receiver and (ii) determine a respective time period for each of the master transmitter and the at least one secondary transmitter in the determined one or more power transmitters to communicate with the power receiver, andthe master transmitter and the at least one secondary transmitter substantially simultaneously transmit the power transmission signals to the power receiver based on respective communications with the power receiver.
