METHOD AND DEVICES FOR TRANSMITTING SIGNAL FROM A PLURALITY OF WIRELESS POWER RECEIVERS TO WIRELESS POWER PROVIDER

摘要

PURPOSE: A method and a device for transmitting signals from multiple wireless power receivers to a wireless power supplier are provided to prevent frequency collisions by using individually different frequencies. CONSTITUTION: Reception signals are inputted into one or more external wireless power receivers(110-1,110-2,110-3,110-4). The reception signals include at least one power communications signal. The existence status of the power communications signals is determined by analyzing the reception signals. A transmission frequency of transmission signals is decided based on the determination result. Transmission data is converted to a transmission signal of the transmission frequency and outputted.
