Band plan

From CECS wiki
Jump to navigation Jump to search

The FCC divides the radio spectrum up into multiple bands for different purposes. (frequency allocation) Each frequency range is allocated to groups of users on either a primary or secondary basis.

Additionally, the amateur bands are further subdivided for specific purposes by mutual agreement. These uses are less formal, more localized, and not always followed strictly.
