Abstract

Methods and devices for surveying for active and inactive power receivers within a wireless-power coverage area are described. A method includes causing performance of a survey looking for active power receivers within a wireless-power coverage area using communication radio(s). Information is received from an active power receiver and transmission of RF signals is caused to energize inactive power receivers using a power-transmission antenna. A first RF signal is transmitted using a first value for a transmission characteristic, and a second RF signal is transmitted using a second value for the transmission characteristic. Additional information is received from a first energized power receiver and further information from a second energized power receiver. Two or more frequency bands are identified for radio-frequency wireless-power transmissions by a wireless-power transmitting device within the wireless-power coverage area based on the information, the additional information, and the further information.
