1. A communication and power control method of a wireless power transmission system, comprising:
- comparing a transmission efficiency to a target device from a source device and a transmission efficiency to the target device from another neighboring source device, through communicating with the target device and the another neighboring source device;
determining that whether the target device is in a magnetic coupling zone of the source device based on the comparison; and
transmitting, by the source device, a power to the target device if the target device is in the magnetic coupling zone of the source device.
