Which organization defines the wireless spectrum as a range of frequencies or bands?

• A. ITU
• B. Federal Communications Commission
• C. National Telecommunications and Information Administration
• D. European Telecommunications Standards Institute

Answer: (B)

Spectrum is the set of radio frequencies allocated for wireless use, described as a range of frequencies or bands. In the United States, the organization that defines and regulates this spectrum—how it’s divided into bands, who may use each band, and what rules apply to avoid interference—is the Federal Communications Commission. The FCC issues licenses, sets power limits, and outlines the permissible uses for different parts of the spectrum, effectively shaping how wireless services operate domestically. Other organizations, like the ITU, provide international coordination, while NTIA and European bodies handle different spheres, but for defining and regulating the spectrum in the U.S., the FCC is the authority.
