Frequency allocation
The allocation of radio frequencies is provided according to ''Article 5'' of the ITU Radio Regulations (edition 2012).
[''ITU Radio Regulations, CHAPTER II – Frequencies, ARTICLE 5 Frequency allocations, Section IV – Table of Frequency Allocations'']
In order to improve harmonisation in spectrum utilisation, the majority of service-allocations stipulated in this document were incorporated in national Tables of Frequency Allocations and Utilisations which is within the responsibility of the appropriate national administration. The allocation might be primary, secondary, exclusive, and shared.
*primary allocation: is indicated by writing in capital letters
*secondary allocation: is indicated by small letters
*exclusive or shared utilization: is within the responsibility of administrations
; Example of
frequency allocation
Frequency allocation (or spectrum allocation or spectrum management) is the allocation and regulation of the electromagnetic spectrum into radio frequency bands, normally done by governments in most countries. Because radio propagation does no ...
