Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. [1] Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation ...
Review of the 88 Expanded Band authorizations made by the Federal Communications Commission on March 17, 1997. [5] In the table below: For the "Original Standard Band Assignment" entries, the FCC's March 17, 1997 notification listed station's call signs and frequencies as of June 30, 1993, dating to when the stations initially notified the commission that they were interested in participating.
In 1986, the FCC allocated an additional 5 MHz of spectrum for each channel block, raising the total amount of spectrum per block to the current total of 25 MHz. [3] The wireline/non-wireline distinction for Cellular Service licensees no longer exists. The 1850–1990 MHz PCS band is divided into six frequency blocks (A through F). Each block ...
FM audio for analog television channel 6 is broadcast at a carrier frequency of 87.75 MHz, and many radios can tune this low; full-power stations ceased analog operations in 2009 under FCC orders, but a very small amount of low-power stations are still operated solely for their right to use this frequency for broadcasting an FM audio carrier ...
The FCC is also responsible for reallocating bands of frequencies to different allocations. As new technologies develop the demand for frequency bands changes and makes some bands more desirable than previously. [8] When this occurs, the FCC may make a decision to move an application to a different band of spectrum to make room for something else.
Class A power was doubled to six kilowatts, and the frequency restrictions noted above were removed. As of late 2004, a station can be "squeezed in" anywhere as long as the location and class conform to the rules in the FCC separation table. [4] The rules for second-adjacent-channel spacing do not apply for stations licensed before 1964.

In the Americas (defined as International Telecommunication Union (ITU) region 2), the FM broadcast band consists of 101 channels, each 200 kHz wide, in the frequency range from 87.8 to 108.0 MHz, with "center frequencies" running from 87.9 MHz to 107.9 MHz. For most purposes an FM station is associated with its center frequency.
