Business band



The business band is the name used by US scanner hobbyists who listen to Federal Communications Commission licensees using Industrial/Business pool frequencies. The regulations listing frequencies in this pool are contained in Subpart C of Part 90, Title 47 CFR.

Artifacts

The pool describes 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, in the USA 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 electromagnetic spectrum between approximately 450 and 470 MHz is used largely for UHF business communications, although this spectrum is not exclusively for business use. In some large metropolitan areas, such as New York, the UHF-T band (between 470 and 512 MHz) is also used, due to congestion on the standard VHF or UHF bands. 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.

History

In the 1980s,[dubious] the FCC acknowledged the need for private frequencies for business to transmit on, and, with congressional authorization, reserved a selection of frequencies in the 450-470MHz range for this purpose.[citation needed] Business Radio Service (BRS) is a collection of 56[dubious] UHF frequencies selected by the FCC, that are reserved exclusively for business use. Many enterprises choose to use these frequencies because they are exclusive, and therefore have less cross-chatter with unaffiliated parties. To obtain a license for conducting transmissions at these frequencies, licensees must be registered as a business with the Internal Revenue Service.[citation needed]
