Which organization sets limitations on radio power, antenna height, and frequency use?

The Federal Communications Commission (FCC) is the regulatory body responsible for setting limitations on radio power, antenna height, and frequency use in the United States. This organization was established to regulate interstate and international communications by radio, television, wire, satellite, and cable.

The FCC's regulations ensure that the radio spectrum is used efficiently, preventing interference between different users and promoting fair access to broadcasting and communication channels. These regulations cover a range of communication services, including public safety communications, ensuring that emergency services can operate effectively without harmful interference from other sources. By establishing these standards, the FCC plays a critical role in managing and protecting the communications landscape.

In contrast, while the National Telecommunications and Information Administration (NTIA) oversees federal radio spectrum use, it does not enforce regulations on commercial users. The American National Standards Institute (ANSI) focuses on setting quality standards across industries, while the Institute of Electrical and Electronics Engineers (IEEE) is primarily involved in developing technical standards for electrical and electronic technologies, not specifically in regulating radio communication practices.
