Abstract
In a wireless power transmitter, a wireless power receiver, and a signal collision avoiding method disclosed herein, when a new wireless power receiver is placed in a specific area while the wireless power transmitter is performing communication with a specific wireless power receiver, the new wireless power receiver analyzes a response signal formed by the specific wireless power receiver through a listening mode, and transmits its own response signal at a collision-avoided time point, thereby allowing an efficient stable data communication.
