Abstract
A system and method for providing positioning freedom, and support of different voltages, protocols, and power levels in a wireless power system. In accordance with an embodiment, the system comprises a base unit having one or more transmitter coils; one or more components including a ferromagnetic, ferrite, or other magnetic material or layer, that modify the magnitude and/or phase of an electromagnetic field in one or multiple dimensions; and one or more components within the base unit and/or the mobile device, for positioning freedom, and support of different voltages, protocols, and power levels. In accordance with various embodiments, the base unit and mobile device can communicate with each other prior to and/or during charging or powering to determine a protocol to be used to charge or power the mobile device.
