Anti interference settings in intercom software programming

Brief Introduction It is difficult to completely avoid interference from various same frequency, adjacent frequency, intermodulation mirror image, and strong electrical signals during the transmission process of wireless communication waves. However, we can use methods such as optimizing parameters technically and conducting preliminary environmental noise interference tests on frequency selection to minimize the impact by
