Wireless power control method based on network, and apparatus and system thereof

The invention object of the present invention can provide a network-based wireless power control method and apparatus and system therefor. Wireless power control method in a serving radio power transmission apparatus according to a first embodiment of the present invention, when power is applied, the method comprising: transmitting a beacon signal using a step and the resonance frequency band which activates the Bluetooth function and wireless power receiving device When the uplink Bluetooth signal is detected, it generated by the second to n-th reception corresponding to the Bluetooth signal from at least one other wireless power transmission apparatus of claim 1 connected to phase and the network to measure the receiver sensitivity for the Bluetooth signals by receiving the basis of the first to the n reception sensitivity it may include determining a transmission availability of wireless power. Accordingly, the present invention has the advantage that can be transferred more effectively wireless power using a plurality of wireless power transmission apparatus connected to a network.
