The FCC, which is an independent regulatory agency, administers spectrum for non-Federal use ( i.e., state, local government, commercial, private internal business, and personal use) and the NTIA, which is an operating unit of the Department of Commerce, administers spectrum for Federal use ( e.g., use by the Army, the FAA, and the FBI).

Within the FCC, the Office of Engineering and Technology ( OET ) provides advice on technical and policy issues pertaining to spectrum allocation and use.

OET maintains the FCCs Table of Frequency Allocations, which is a compilation of allocations.

For a more detailed description go to the Table of Frequency Allocations Chart.

Note: The print edition of Title 47 of the Code of Federal Regulations is revised yearly to include all final rules that amended the Table of Frequency Allocations and that were published in the Federal Register prior to October 1st.

By contrast, the Commission regularly updates its Online Table of Frequency Allocations shortly after a final rule has been released.

The History File contains the complete citation for each document, including information concerning its publication in the Federal Register and in the FCC Record.

If a box (which represents a frequency band) is revised, then the changes are fully explained in the History File.

Note: On October 4, 2004, the format of the History File was revised and some of the features described above are only available as of that date.
