Frequency allocation
The allocation of radio frequencies is provided according to Article 5 of the ITU Radio Regulations (edition 2012).
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 with-in 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 (see example below)
- secondary allocation: is indicated by small letters (see example below)
- exclusive or shared utilization: is within the responsibility of administrations
