Which federal agency regulates all radio frequencies and radio airwaves?

• A. NASA
• B. FCC
• C. NIST
• D. NSA

Answer: (B)

Controlling and coordinating the radio spectrum so different services don’t interfere is the job of a national regulator. The Federal Communications Commission manages most of the radio airwaves in the United States, issuing licenses for broadcasters, wireless networks, and many other devices, and setting rules on how frequencies are used and how much power can be transmitted. This oversight helps prevent harmful interference and keeps communications reliable for things like emergency services, television, radios, and cell networks.

NASA is a space agency focused on space exploration and mission communications, not regulating the spectrum. NIST works on standards and measurements, not licensing or spectrum management. NSA handles national security and intelligence, not overseeing radio frequencies. The spectrum is a shared, limited resource that needs centralized management to keep all these communications orderly and safe.
