1. A system for selecting which power transmitter should deliver wireless power to a device in a wireless power delivery network, the system comprising:

  • a plurality of power transmitters, each respective power transmitter communicatively coupled to a respective transmitter manager, the plurality of power transmitters including;

    a first power transmitter communicatively coupled to a first transmitter manager that is configured to detect, based on communication signals received from a wireless power receiver, a first signal strength level associated with the wireless power receiver and;

    a second power transmitter communicatively coupled to a second transmitter manager that is configured to detect, based on communication signals received from the wireless power receiver, a second signal strength level associated with the wireless power receiver;

    wherein;

    when the first signal strength level is greater than the second signal strength level, the first transmitter manager instructs the first power transmitter to transmit radio frequency (RF) power waves to the wireless power receiver; and

    when the second signal strength level is greater than the first signal strength level, the second transmitter manager instructs the second power transmitter to transmit RF power waves to the wireless power receiver;

    the wireless power receiver is configured to convert energy from the RF powers waves into usable power for charging the wireless power receiver or a device that is coupled with the wireless power receiver.
