Frequency Allocation is provided according to Article 5 of the ITU Radio Regulations, specifically in the most recent version, Edition of 2020.

In order to improve harmonisation in spectrum utilisation, the majority of service-allocations are incorporated in national Tables of Frequency Allocations and Utilisations, which is within the responsibility of the appropriate national administration.

A different take: Defence High Frequency Communications Service

Primary allocation is indicated by writing in capital letters, while secondary allocation is indicated by small letters. Exclusive or shared utilization is within the responsibility of administrations.

Here's a breakdown of frequency allocation for the fixed-satellite service:

Frequency allocation is a complex process that requires careful consideration of various factors. The ITU-R's allocation table is a crucial resource for this process, as it provides a standardized framework for assigning frequencies to different services.

The ITU-R's allocation table divides the frequency spectrum into different bands, each with its own set of allocated frequencies. This table is updated periodically to reflect changes in technology and user needs.

In the VHF band, frequencies between 30 MHz and 300 MHz are allocated for use by various services, including broadcasting and mobile communications. The allocation of these frequencies is crucial for ensuring that different services do not interfere with each other.

The use of frequency allocation tables like the ITU-R's can help to prevent interference and ensure that different services operate smoothly. This is particularly important in cases where multiple services are using the same frequency band.

In some cases, frequency allocation can be dynamic, with frequencies being allocated or reallocated in response to changing user needs. This can be seen in the way that the ITU-R's allocation table is updated to reflect changes in technology and user needs.

The allocation of frequencies in the VHF band has been particularly important for broadcasting and mobile communications services. In the 1970s, the ITU-R allocated frequencies in this band for use by mobile radio services, paving the way for the development of modern mobile communications.
