Frequency allocation

This page was last edited on 15 March 2018, at 20:26.

Frequency allocation (or spectrum allocation or spectrum management) is the allocation and regulation of the electromagnetic spectrum into radio frequency bands, which is normally done by governments in most countries.[1] Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation of RF bands and their standardization.

ITU definition

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".[2]

Frequency allocation is also a special term, used in national frequency administration. Other terms are:

Bodies

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. Allocations are:

  • primary: indicated by writing in capital letters
  • secondary: indicated by small letters
  • exclusive or shared utilization: within the responsibility of administrations.

However, in military usage, in bands where there is civil usage, will be in accordance with the ITU Radio Regulations. In NATO countries, military mobile utilizations are made in accordance with the NATO Joint Civil/Military Frequency Agreement (NJFA).
