Abstract

The invention relates to reduced jamming between receivers and wireless power transmitters. Exemplary embodiments are directed to reducing jamming caused by radiated fields generated by wireless power transmitters. Exemplary embodiments include detecting a jamming condition of a wireless power receiving device resulting from a radiated field from a wireless power transmitter of a charging device. Such embodiments include synchronizing the wireless power coupling with communication of the wireless power receiving device. Synchronizing wireless power coupling may include wireless power coupling at a first level when the wireless power receiving device is expected to receive a signal on a communication channel. Synchronizing wireless power coupling may further include coupling at a higher rate when the wireless power receiving device is not expected to receive a signal on the communication channel.
