1. A method comprising:
- transmitting, by a wireless power source, a signal with a first characteristic via an in-band communication channel;
receiving via an out-of band communication channel, by the wireless power source, information from a first wireless power device; and
determining, by the wireless power source, if the information includes the first characteristic.

Abstract
Improved configurations for wireless energy transfer can include system elements of a wireless energy transfer system that may pair in-band and out-of-band communication channels by exchanging related information. Energy transfer signals may be modulated according to defined waveforms. Information about the signal may be transmitted using an out-of-band communication channel. A system element that receives both the signal and information may verify that they correspond to the same system element.
