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 ...
The 2015 ITU World Radiocommunication Conference (WRC-15) approved a new worldwide frequency allocation of 5.351.5–5.366.5 MHz to the amateurs on a secondary basis. The allocation limits amateur stations to 15 watts effective isotropic radiated power (EIRP); however some locations will be permit up to 25 W EIRP.
The 9-centimeter band is a portion of the SHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The amateur radio band, in ITU regions 1 and 2, is between 3.300 GHz and 3.500 GHz, and it is available only on a secondary basis.
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.
The following table lists terrestrial television channels in the ultra high frequency band as they were allocated in their modern form by the Federal Communications Commission on April 11, 1952. The original allocation included 70 UHF channels (14–83) with 6 MHz separation.

The 3-centimeter or 10 GHz band is a portion of the SHF radio spectrum internationally allocated to amateur radio and amateur satellite use on a secondary basis. The amateur radio band is between 10.00 GHz and 10.50 GHz, and the amateur satellite band is between 10.45 GHz and 10.50 GHz.
The 5-centimeter or 5 GHz band is a portion of the SHF radio spectrum internationally allocated to amateur radio and amateur satellite use on a secondary basis. In ITU regions 1 and 3, the amateur radio band is between 5,650 MHz and 5,850 MHz.
