1. A method for applying wireless power for charging a wireless power receiver by a wireless power transmitter, the method comprising:
- detecting a change in impedance of the wireless power transmitter caused by a placement of the wireless power receiver;
applying driving power for the wireless power receiver, in response to detecting the change;
receiving a signal from the wireless power receiver, wherein the driving power is used to transmit the signal from the wireless power received to the wireless power transmitter;
establishing a communication network with the wireless power receiver, wherein the communication network is associated with the signal;
registering the wireless power receiver in a wireless power network managed by the wireless power transmitter by using the established communication network; and
applying charging power for the wireless power receiver.
