The embodiments described herein include a transmitter that transmits a power transmission signal (e.g., radio frequency (RF) signal waves) to create a three-dimensional pocket of energy. At least one receiver can be connected to or integrated into electronic devices and receive power from the pocket of energy. The transmitter can locate the at least one receiver in a three-dimensional space using a communication medium (e.g., Bluetooth technology). The transmitter generates a waveform to create a pocket of energy around each of the at least one receiver. The transmitter uses an algorithm to direct, focus, and control the waveform in three dimensions. The receiver can convert the transmission signals (e.g., RF signals) into electricity for powering an electronic device. Accordingly, the embodiments for wireless power transmission can allow powering and charging a plurality of electrical devices without wires.
