Abstract
A wireless charging network system is disclosed that includes wirelessly charged sensor nodes. The wireless network system can include a gateway node configured to aggregate data from sensor nodes within a coverage area of the gateway node. The gateway node is further configured to wirelessly transmit power to the sensor nodes using a beamformed signal, wherein the gateway node adjusts the beamformed signal to maximize wireless power transfer to sensor nodes within each sector of the coverage area. Location information can be used to adjust the beamformed signal. For example, in various embodiments, the gateway node includes a beamformer sector profile table that defines channel adaptive beam profiles for the beamformed signal for each sector of the coverage area. The gateway node can use location information to define the beam profiles.
