FCC

The Federal Communications Commission (FCC) is a U.S. government agency established by the United States Congress. It oversees broadcasting and telecommunications businesses within the United States. The FCC's scope of supervision includes not only radio frequencies but also electronic devices that emit radio waves. Therefore, when selling wireless devices or electronic equipment that emits radio waves in the United States, it is necessary to ensure compliance with FCC regulations.
