The agency responsible for regulating radio communications in the United States is the Federal Communications Commission (FCC). The FCC oversees all non-federal use of the radio spectrum, managing frequencies to ensure interference-free communication for various services, including public safety, broadcasting, and commercial communications.
This role is critical in maintaining an organized approach to the use of radio frequencies and preventing overlapping communications that could impede emergency services and other essential operations. The FCC establishes regulations that telecommunications and broadcasting companies must adhere to, ensuring a structured and efficient use of communication resources.
In contrast, the other options represent agencies with different responsibilities: FEMA focuses on disaster management and response, the FDA oversees food and drug safety, and NIH conducts medical research. Each of these agencies plays a vital role in their respective fields, but they do not have jurisdiction over radio communication regulations.
