Abstract
Various embodiments comprise systems, methods, architectures, mechanisms or apparatus providing far-field wireless charging of implanted medical devices, Internet of Things (IoT) and the like via a leader radio configured for receiving spread spectrum (SS) modulated radio waves from a plurality of slave radios within an area including the leader radio and a target device, for receiving from the target device backscatter radio energy associated with the (SS) modulated radio waves, and for generating slave radio control signals; the leader radio, in a charging mode of operation, being configured for determining changes in received power associated with backscatter radio energy received from the target device and responsively transmitting control signals toward the slave radios configured to cause the slave radios to modify respective radio wave transmission times such that slave radio wave transmissions are substantially phase aligned when received at the target device.
