Dynamic operation adjustment in wireless power transfer system

A wireless power transfer system comprising:

• a wireless transmission system, the wireless transmission system having:
• an input to receive input power from an input power source;
• a transmission antenna configured to couple with a receiver antenna associated with a wireless receiver system in a peripheral device;
• a transmission controller configured to:
• generate AC wireless signals based, at least in part, on the input power, the AC wireless signals including wireless power signals and wireless data signals, transmit the AC wireless signals to the receiver antenna via the transmission antenna, derive a coupling factor for the transmission based on coupling data sent from the wireless receiver system to the wireless transmission system, generate an update frequency based on the derived coupling factor, and to transmit the update frequency to the wireless receiver system in the peripheral device, whereby the peripheral device provides coupling data to the wireless transmission system based on the update frequency.
