Which agency regulates the design, installation, and operation of two-way radio systems?

The Federal Communications Commission (FCC) is the agency responsible for regulating two-way radio systems, among other communication technologies. This includes overseeing the allocation of radio frequencies, licensing of radio operators, and ensuring compliance with federal standards related to radio communications. The FCC's role is crucial in preventing interference between different communication systems and ensuring that emergency services, such as fire and police departments, can operate effectively using radio communications.

By managing the technical specifications and operational guidelines, the FCC helps maintain safety and reliability within communication networks that are vital during emergencies. This regulatory oversight ensures that fire departments and other emergency responders can effectively communicate with one another and coordinate their efforts during incidents. Other agencies, such as the FAA (Federal Aviation Administration), focus on aviation, and the FDA (Food and Drug Administration) oversees food and drug safety, while FCA (Farm Credit Administration) pertains to agricultural financing, making them unsuitable for the regulation of two-way radio systems.
