Frequency Allocation Table

Introduction

The National Frequency Table of Allocations is a compendium of frequency allocations to services applicable to Nigeria as well as a depiction of frequency usage in Nigeria. This table has been developed and periodically reviewed in conformity with the international regulations governing radio spectrum and the international/ regional agreements acceded to by the Federal Republic of Nigeria in the capacity of the National Frequency Management Council. After each World Radiocommunication Conference, as convened by the International Telecommunication Union (ITU), reviews to the table are made to reflect additions and modifications resulting from these conferences.

This table conveys the nation’s compendium prior to the World Radiocommunication Conference of 2015. The objective of developing and sustaining a National Table of Frequency Allocation is to promote spectrum discipline, increase efficiency and usage.
 

Table of Allocations

For the purpose of frequency allocation, the world is divided into three regions. Nigeria falls within Region 1. Article 5 of the Radio Regulations deal with these frequency allocations which have been made from 8.3KHz to 300GHz. It is mandatory for all administrations to adhere to these allocations. The table of allocations show the allocated spectrum bands, which are classified into six ranges (i.e. segments) where each segment represents a range of frequencies. Each of the six segments are presented using five columns as follows.

  1. Frequency Bands: The frequency bands constituting the allocated portion of the spectrum are outlined in the Frequency Bands column.
  2. ITU Region 1 Allocations: The column for ITU Region 1 Allocations specifies the services tied to the various frequency bands for Region 1.
  3. Nigerian Allocations: For each band, the column Nigerian Allocation outlines the services for which allocations could be made by the administrator.
  4. Nigerian Utilization: The column for Nigerian Utilization details the services actually deployed within each band.
  5. Remarks: Further information on band sharing/coordination, usage and (or) technical specifications are portrayed in the column termed Remarks.

Services are allocated either on a primary or secondary basis. If a frequency band is allocated to more than one service, such services are distinguished to reflect their status as either primary or secondary allocations. Primary services are prinited in UPPERCASE letters while secondary services are in lowercase letters with the first letter capitalized. According to technical specfications of the Radio Regulations developed for band sharing between services, stations providing secondary services are restricted from the following;

  1. Causing harmful interference to stations of primary service to which frequencies are already assigned or to which frequencies could be subsequently assigned.
  2. Claiming protection from harmful interference from stations of a primary service to which frequencies are already assigned or could be subsequently assigned

Stations providing secondary services are not restricted from claiming protection, however, from harmful interference from station of the same or other secondary services(s) to which frequencies could be subsequently assigned.

The National Frequency Table of Allocations (separated by Segment) is presented below;

Footnotes

Footnotes provide further information on allocation as well as specifications perculiar to certain bands. These footnotes further illustrate how certain bands are to be utilized. In this document, footnotes applicable to Nigeria have been compiled and presented for easy referencing.

This page contains all the international and country footnotes applicable to spectrum management and administration in Nigeria.
