Systems and methods are described for receiving wireless power and providing wired power. In some embodiments, a predictive phase estimation apparatus comprises a transceiver module configured to receive a plurality of beaconing signals from a wireless client during a beacon cycle. The predictive phase estimation apparatus also comprises a phase compensation module configured to store the received plurality of beaconing signals, a phase predictor module is coupled to the transceiver module and configured to calculate predictive phases based on the received plurality of beaconing signals and based on beaconing signals received from the wireless client prior to the beacon cycle, and a signal converter coupled to the transceiver module. The signal converter is configured to form transmission signals based on the predictive phases and supply the transmission signals to the transceiver module. The transceiver module also transmits the transmission signals for delivery of wireless power to the wireless client.
