Techniques for forming a wireless RF power harvesting and data network are described. An example electronic device includes an antenna array, a processor, and instructions to direct the actions of the processor. The instructions control the processor to perform a registration process for a power harvesting device. The registration process is to obtain information that enables the transmission of a targeted power packet to the power harvesting device through beamforming. The instructions also direct the processor transmit the targeted power packet to the power harvesting device.
