A method for selecting which power transmitter should deliver wireless power to a device in a wireless power delivery network, the method comprising: at a management system comprising a cluster of wireless power transmitters, including a first power transmitter, a second power transmitter and a plurality of wireless power transmitter managers: determining that the first power transmitter and the second power transmitter are within a power transfer range of a wireless power receiver, the wireless power receiver being separate from the management system; designating, by the management system, a first transmitter manager that is communicatively coupled to the first power transmitter as a master transmitter of the cluster of wireless power transmitters, wherein the master transmitter is configured to control order and timing of communications with the wireless power receiver among power transmitters in the cluster of wireless power transmitters that are within the power transfer range of the wireless power receiver, wherein each power transmitter in the management system builds a list of all power transmitters of the wireless power delivery network, including identification of one of the power transmitters designated as the master transmitter, the designating of the first transmitter manager as the master transmitter being based on the respective lists built by each power transmitter and that the first power transmitter is not off line; instructing the master transmitter to grant the wireless power receiver access to wireless power transmissions from the first power transmitter and the second power transmitter, wherein the first power transmitter and the second power transmitter transmit radio frequency, RF, power waves to the wireless power receiver after the access is granted, 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 management system comprising a cluster of wireless power transmitters, including a first power transmitter, a second power transmitter and a plurality of wireless power transmitter managers: determining that the first power transmitter and the second power transmitter are within a power transfer range of a wireless power receiver, the wireless power receiver being separate from the management system;
