Abstract
A wireless signal interference reduction device includes a digital signal converter, an output device, a first adjustable resistor, and a second adjustable resistor. The wireless signal interference reduction device records an initial SNR value, records an SNR value of wireless reception in real-time at a preset interval when wired data transmission is turned on, determines whether a difference between the initial SNR value and the real-time SNR value is less than a preset value, continuously obtains the real-time SNR value at the preset interval to obtain the difference between the initial SNR value and the real-time SNR value if the difference between the initial SNR value and the real-time SNR value is less than the preset value, and reduces the wired transmission bandwidth by one step value if the difference between the initial SNR value and the real-time SNR value is not less than the preset value.
