Provided is a base unit for wireless power transfer or charging through a time varying magnetic field, comprising. The unit may include one or more components including a magnetic material or layer, that guide a corresponding magnetic flux generated by a coil in the base unit in one or multiple dimensions and/or to guide the magnetic flux in such a manner as to create a preferential path for returning flux flow in one or multiple dimensions. When one or more power receivers, each having one or more receiver coils or receivers associated therewith, is placed in proximity to a base unit, the coil in the base unit is used to inductively generate a current in the one or more receiver coils or receivers associated with the one or more power receivers. The base unit and the one or more receivers communicate uni-directionally or bi-directionally through the coils by load modulation or another RF communication method including NFC, Bluetooth or WiFi communication to control and optimize the power transfer between the base unit and the one or more receivers.
