The device disclosed in the specification comprises: a power pickup unit configured to receive wireless power from a wireless power transfer device having a plurality of primary coils at an operation frequency by magnetic coupling to the wireless power transfer device and convert an alternating current signal generated by the wireless power into a direct current signal; a communication/control unit including an in-band communication module configured to be supplied with the direct current signal from the power pickup unit and perform communication with the wireless power transfer device by using the operating frequency, and an out-band communication module configured to perform communication with the wireless power transfer device by using a frequency other than the operating frequency; and a load configured to be supplied with the direct current signal from the power pickup unit. In a one-to-multiple wireless power transfer system using a multi-coil, various applications of wireless power can be efficiently supported by defining configuration information, control information, management information, and procedures for the exchanges thereof as an out-band communication protocol."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for two-channel communication in a wireless power transfer","description":"The present disclosure relates to a device and method for wireless power transfer to multiple devices using a multi-coil.
