1. A method of secure wireless transmission of power using unidirectional communication signals from a wireless-power-receiving device, comprising:
receiving, from a wireless-power-transmitting device that includes a first communications radio, a first wireless-power-transmission signal at the wireless-power-receiving device that includes a second communications radio;
in response to receiving the first wireless-power-transmission signal:
broadcasting, via the second communications radio of the wireless-power-receiving device and without establishing a communications channel between the first and second communications radios, a first data packet that includes information identifying (i) at least one power requirement of a power source of the wireless-power-receiving device and (ii) an amount of power received by the wireless-power-receiving device from the first wireless-power-transmission signal;
receiving, from the wireless-power-transmitting device, a second wireless-power-transmission signal at the wireless-power-receiving device;
in response to receiving the second wireless-power-transmission signal, broadcasting, via the second communications radio of the wireless-power-receiving device and without establishing a communications channel between the first and second communications radios, a second data packet that includes information indicating that the power source is charging but needs more power, wherein the wireless-power-transmitting device is configured to utilize the information indicating that the power source is charging but needs more power to adjust characteristics of wirelessly transmitted power waves to increase an amount of power provided to the wireless-power-receiving device;
receiving, from the wireless-power-transmitting device, a third wireless-power-transmission signal at the wireless-power-receiving device; and
in response to receiving the third wireless-power-transmission signal, broadcasting, via the second communications radio of the wireless-power-receiving device and without establishing a communications channel between the first and second communications radios, a third data packet that includes information indicating that the power source is charging but is receiving too much power, wherein the wireless-power-transmitting device is configured to utilize the information indicating that the power source is charging but is receiving too much power to adjust characteristics of wirelessly transmitted power waves to decrease an amount of power provided to the wireless-power-receiving device.
