NETWORK-BASED WIRELESS POWER CONTROL METHOD, AND WIRELESS POWER CONTROL DEVICE AND SYSTEM
First Claim
1. A method for controlling wireless power by a wireless power transmission apparatus for wirelessly transmitting power to a wireless power reception apparatus, the method comprising:
- transmitting a first signal through a first frequency band when power is applied;
measuring, when a second signal corresponding to the first signal is received through the second frequency band, a first reception sensitivity of the second signal,receiving second to n-th reception sensitivities corresponding to the second signal from at least one other wireless power transmission apparatus connected to a network, a reception sensitivity; and
determining whether to transmit wireless power to the wireless power reception apparatus based on the first to n-th reception sensitivities.

Abstract
The purpose of the present invention relates to a network-based wireless power control method, and a device and a system therefor. A wireless power control method, in a wireless power transmission device which wirelessly transmits power to a wireless power reception device, according to a first embodiment of the present invention, comprises the steps of: transmitting a first signal via a first frequency band when a power source is applied; when a second signal corresponding to the first signal is received via a second frequency band, measuring the first reception sensitivity of the second signal; receiving second to n-th reception sensitivities corresponding to the second signal from at least one other wireless power transmission device connected via a network; and determining whether power has been wirelessly transmitted to the wireless power reception device, on the basis of the first to n-th reception sensitivities. As such, the present invention has an advantage of being capable of more effectively transmitting power wirelessly by using a wireless power transmission device connected via a network.
