broadcast spectrum
Radio frequency allocation
The broadcast spectrum is the range of radio frequencies allocated for transmitting television and radio signals to the public.
Government agencies regulate who can use which frequencies to prevent interference between stations.
The term often appears in debates about spectrum allocation: Wireless companies are lobbying to buy portions of the broadcast spectrum.
