Abstract
A wireless charging platform for a wireless sensor network is disclosed, which includes a radio frequency energy distributor and data aggregator (REDDA) system configured to aggregate data from sensor nodes and wirelessly transmit power to the sensor nodes using a beamformed RF signal. The REDDA system can set a radiation pattern for the beamformed RF signal that maximizes RF energy transfer to the sensor nodes based on an environment associated with the sensor nodes. In various embodiments, the REDDA system can include an Internet of Things (IoT) interface connected to an IoT network, and the REDDA system can use information gleaned from the IoT network to set the radiation pattern.
