Frequency allocation

[1] Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation of RF bands and their standardization.

The International Telecommunication Union defines frequency allocation as being of "a given frequency band for the purpose of its use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specified conditions".

Other terms are: Several bodies set standards for frequency allocation, including: To improve harmonisation in spectrum utilisation, most service allocations are incorporated in national Tables of Frequency Allocations and Utilisations within the responsibility of the appropriate national administration.

In NATO countries, military mobile utilizations are made in accordance with the NATO Joint Civil/Military Frequency Agreement (NJFA).

Some of the bands listed (e.g., amateur 1.8–29.7 MHz) have gaps / are not continuous allocations.
