Wireless power transfer system with data versus power priority optimization

A method for operating a wireless power transfer system, the wireless power transfer system including a wireless power transmission system and a wireless power receiver system, the wireless power transmission system configured to couple with the wireless power receiver system and transmit alternating current (AC) wireless signals to the wireless power receiver system, the AC wireless signals including wireless power signals and wireless data signals, the method comprising:

• determining, using an integrated circuit of the wireless power transmission system, an operating mode for transmission of the AC wireless signals, wherein the operating mode includes a power level for the wireless power signals and a data rate for the wireless data signals, the power level chosen from a series of available power levels and the data rate chosen from a series of available data rates, each of the series of available power levels corresponding to one of the series of available data rates, wherein corresponding pairs of available power levels and available data rates are inversely related;
• performing, using the integrated circuit of the wireless power transmission system, one or more of encoding the wireless data signals, decoding the wireless data signals, receiving the wireless data signals, transmitting the wireless data signals or combinations thereof;
• providing, using the integrated circuit of the wireless power transmission system, a driving signal to an amplifier of the wireless power transmission system, the driving signal based on an operating frequency for the wireless power transfer system and the operating mode;
• and
• driving a transmitter antenna of the wireless power transmission system, by the amplifier, based on the driving signal.

A device comprising:

• a transmitter antenna configured to couple with at least one other antenna and transmit alternating current (AC) wireless signals to the at least one other antenna, the AC wireless signals including wireless power signals and wireless data signals;
• and
• an integrated circuit including
• a controller that is configured to:
• (i) provide a driving signal for driving the transmitter antenna based on an operating frequency and an operating mode for transmission of the AC wireless signals,
• (ii) perform one or more of encoding the wireless data signals, decoding the wireless data signals, receiving the wireless data signals, or transmitting the wireless data signals, and
• (iii) determine the operating mode for transmission of the AC wireless signals, wherein the operating mode includes a power level for the wireless power signals and a data rate for the wireless data signals, the power level chosen from a series of available power levels and the data rate chosen from a series of available data rates, each of the series of available power levels corresponding to one of the series of available data rates, wherein corresponding pairs of available power levels and available data rates are inversely related.
