Business band
The business band is a series of frequencies on the VHF and UHF two-way radio bands. They are reserved for use by businesses, and, although the requirement is sometimes overlooked, they require a license from the Federal Communications Commission prior to use. The exception to this is five specific frequencies that are now part of the Multi-Use Radio Service, which permits unlicensed operation on these frequencies, provided the output power does not exceed 2 watts.
The spectrum between approximately 462 and 467 MHz is used largely for UHF business communications, although this spectrum is not exclusively for business use only. There are also a number of specific frequencies, in both the VHF and UHF spectrum, that are for business use; most of these have color-coded names, such as Blue Dot or Red Star.
