WIRELESS POWER TRANSMISSION METHOD FOR PREVENTING FREQUENCY INTERFERENCE
First Claim
1. A wireless power transmission method for preventing frequency interference in a wireless power system including a wireless power transmitter and an adjacent-frequency-using apparatus, the method comprising:
- generating and transmitting, by the wireless power transmitter, a power signal to the adjacent frequency-using apparatus;
receiving, by the adjacent-frequency=using apparatus, the power signal and obtaining power from the power signal; and
generating and transmitting, by the adjacent-frequency-using apparatus, a power transmission restriction signal to the wireless power transmitter when preparing for an operation start.
