1. A system for transmitting wireless power, the system comprising:
- a processor;
a memory coupled to the processor and storing instructions for transmitting wireless power and receiving beacon signals from a client device according to a power delivery schedule and beacon schedule, respectively;
a clock source configured to synchronize transmission of wireless power;
at least four antenna management units (AMUs) configured to transmit radio frequency (RF) wireless power and receive beacon signals from the client device,wherein each of the AMUs includes;
a transceiver configured to switch between receiving the beacon signals from the client device and transmitting an RF power waveform to the client device;
a phase shifter configured to adjust a phase of the RF power waveform based on the received beacon signals; and
a phase detector configured to detect a phase of the received beacon signals,wherein each transceiver is configured to concurrently transmit the RF power waveform to the client device; and
at least one an antenna coupled to each of the AMUs.

14. A tangible computer-readable storage medium containing machine-implementable instructions which, when executed by a system having at least four antenna management units (AMUs), cause the system to:
-
transmit a beacon signaling schedule to a client device; send a control signal to a transceiver directing the transceiver to switch an antenna from transmitting wireless power to receiving beacon signals; process a beacon signal of the beacon signals received from the client device, wherein the beacon signal is received in accordance with the beacon signaling schedule; amplify the received beacon signal; detect a phase of the amplified beacon signal; determine an adjusted phase for transmitting wireless power to the client device at least partially based on the detected phase of the amplified beacon signal; send control instructions to a phase shifter for transmitting the adjusted phase wireless power; amplify the adjusted phase wireless power for the client device; and transmit the adjusted phase wireless power to the client device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
