Abstract
In one embodiment, a method includes wirelessly coupling a transmitter to a wireless device; determining a first power transfer value of a signal transmitted from the transmitter to the wireless device with a first transmit impedance; determining a second power transfer value of the signal transmitted from the transmitter to the wireless device with a second transmit impedance; and selecting the first transmit impedance based on received power-level information indicating that the first power transfer value is greater than the second power transfer value.
