14. A method of operating a wireless power and data transfer system through commercial packaging, the method comprising:
determining, by a wireless transmission system, a presence of a wireless receiver system;
starting wireless power and data transfer via the wireless transmission system, if the presence of the wireless receiver system is detected, wherein wireless data transfer via the wireless transmission system comprises transferring a universal asynchronous receiver-transmitter (UART) compliant data signal via near field magnetic induction in accordance with a Near Field Communication (NFC) data transfer protocol, wherein the UART compliant data signal is packetized in a synchronous NFC data stream having a header with a synchronizing command and length command;
determining, by the wireless transmission system, an impedance across the wireless transmission system and wireless receiver system;
determining, by the wireless transmission system, the power at a load associated with the wireless receiver system based on the determined impedance;
determining, by the wireless transmission system, if power at a load associated with the wireless receiver system exceeds a threshold for out of band communications; and
if the power at the load exceeds the threshold for out of band communications, handing over the wireless data transfer to an out of band communications system that is in operative communication with the wireless transmission system.
