A method for selecting which power transmitter should deliver wireless power to a device paired with a wireless power receiver in a wireless power delivery network, the method comprising: at a 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 and a second power transmitter communicatively coupled to a second transmitter manager, detecting, by the first transmitter manager, based on communication signals received from the wireless power receiver, a first signal strength level associated with the wireless power receiver; detecting, by the second transmitter manager, based on communication signals received from the wireless power receiver, a second signal strength level associated with the wireless power receiver; instructing, by the first transmitter manager, the first power transmitter to transmit radio frequency power waves to the wireless power receiver when the first signal strength level i) is greater than the second signal strength level, ii) is greater than a signal strength threshold, and iii) has been greater than the signal strength threshold for a minimum amount of time; and instructing, by the second transmitter manager, the second power transmitter to transmit RF power waves to the wireless power receiver when the second signal strength level i) is greater than the first signal strength level, ii) is greater than the signal strength threshold, and iii) has been greater than the signal strength threshold for the minimum amount of time, wherein 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. at a 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 and a second power transmitter communicatively coupled to a second transmitter manager, detecting, by the first transmitter manager, based on communication signals received from the wireless power receiver, a first signal strength level associated with the wireless power receiver; detecting, by the second transmitter manager, based on communication signals received from the wireless power receiver, a second signal strength level associated with the wireless power receiver; instructing, by the first transmitter manager, the first power transmitter to transmit radio frequency power waves to the wireless power receiver when the first signal strength level i) is greater than the second signal strength level, ii) is greater than a signal strength threshold, and iii) has been greater than the signal strength threshold for a minimum amount of time; and instructing, by the second transmitter manager, the second power transmitter to transmit RF power waves to the wireless power receiver when the second signal strength level i) is greater than the first signal strength level, ii) is greater than the signal strength threshold, and iii) has been greater than the signal strength threshold for the minimum amount of time, wherein 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.
