A power transmitting unit receives, from a power receiving unit, a first out-of-band communication signal identifying the power receiving unit as being available to receive wireless power. The power transmitting unit transmits, to the power receiving unit, a second out-of-band communication signal including a request to transfer useful amounts of wireless power and receives a third out-of-band communication signal including first information about power transfer capability of the power receiving unit. The power transmitting unit transmits, to the power receiving unit, a fourth out-of-band communication signal including second information about power transfer capability of the power transmitting unit, and initiates transmission of the useful amounts of wireless power to the power receiving unit by verifying compatibility of the power transfer capability of the power transmitting unit and the power receiving unit based on the first information and the second information. |
