No part of this document may be produced by any process without prior written permission from the Frequency Allocation Board. This document contains texts derived from the International Telecommunication Union (ITU) Radio Regulations and the responsibility for reproduction lies with the Frequency Allocation Board and in no way be attributed to the ITU. Page 2 of 117 FREQUENCY ALLOCATION BOARD PREFACE Radio frequency spectrum is the range of electromagnetic waves over which radio waves can be radiated and is depicted by a tabulation of uses of radio waves arranged in ascending frequency order. Radio frequency spectrum, which is naturally available, is a scarce national resource susceptible to harmful interference and international in character since radio waves can not be confined to national boundaries. Like any other natural resource, radio frequency cannot be owned but shared amongst various services, users, technologies etc. Radio frequency spectrum has great potential of generating socio-economic activities in a country. It is a key input into many vital public services affecting the quality and safety of life of citizens. Radio frequency spectrum contributes to a diverse array of cultural, social and scientific activities. Radio spectrum enables communication across many different media, for many different purposes, individual and collective, commercial and non-commercial. The growth in the use of the mobile telephones, internet, TV broadcasting is a manifestation of the attraction of communication in all its electronic forms to very broad sections of society.
