The present invention relates to a wireless power transfer network and a wireless power transfer method and more specifically, to a wireless power transfer network which wirelessly transfers power using a magnetic field and performs in-band communication through the magnetic field used for the wireless power transfer, and a wireless power transfer method using the same. According to an embodiment of the present invention, the wireless power transfer method is performed by a base station in a wireless power transfer network which performs wireless power transfer using a magnetic field and performs the in-band communication through the magnetic field, and comprises the base station and one or more electronic devices which receive power. The wireless power transfer method comprises: a step of transmitting a first magnetic field signal to one or more electronic devices; a step of receiving a second magnetic field signal including information regarding which area among a charging area and a communication area the second magnetic field signal is included in, as a response to the first magnetic field signal from one or more electronic devices; and a step of supplying power to the electronic device included in the charging area, among one or more electronic devices, using the magnetic field. |
