Disclosed in the present invention are a channel interference avoiding circuit, method and device thereof, the circuit comprising a Wireless Fidelity (WiFi) chip, and at least one first single-pole multi-throw switch. A movable end of the first single-pole multi-throw switch is connected to a signal transmission pin of the WiFi chip, and the first single-pole multi-throw switch comprises at least two fixed ends, a first fixed end of the at least two fixed ends is connected to a first signal transmission branch and a second fixed end of the at least two fixed ends is connected to a second signal transmission branch comprising a power attenuator, and an input end of the power attenuator is connected to the second fixed end of the first single-pole multi-throw switch. When determining that a first channel and a second channel interfere with each other, the WiFi chip controls the movable end of the first single-pole multi-throw switch to connect to the second fixed end of the first single-pole multi-throw switch, the first channel is a WiFi channel, and the second channel is different from the WiFi channel. |
