  • This revision of the Handbook on National Spectrum Management involved a major update and expansion of the 1995 edition. It was developed by a Rapporteur Group established for this purpose by Radiocommunication Study Group 1. Mr. Robert J. Mayher, former Chairman of Study Group 1 served as Rapporteur of the group, assisted by the Counsellor, Mr. Dusan Schuster. Members responsible for revisions to the chapters included Mr. Steven Bond, Mr. Dave Barrett, Mr. Howard Del Monte, Mr. William Luther, Mr. Philippe Mège, Mr. Alexandre Pavliouk, Mr. Thomas Racine, Mr. Jan Verduijn and Mr. Roy Woolsey.

  • Society’s increasing use of radio-based technologies, and the tremendous opportunities for social development that these technologies provide, highlight the importance of radio-frequency spectrum and national spectrum management processes. Technological progress has continually opened doors to a variety of new spectrum applications that have spurred greater interest in, and demand for, the limited spectrum resource. Increased demand requires that spectrum be used efficiently and that effective spectrum management processes be implemented. In this framework, modern data handling capabilities and engineering analysis are important to accommodate the variety of potential users seeking access to the spectrum.

  • The purpose of any planning effort is to organize and focus thoughts and actions for the efficient and effective achievement of directed, or agreed goals and objectives. This effort is important for any country (and especially important for developing countries) which wants to initiate or improve a national spectrum management process.

  • This Chapter considers regulatory and technical aspects of the frequency assignment and licensing process for national radio systems. On one hand, frequency assignments must provide for the normal operation of existing radio systems as well as for new systems with a specified performance. On the other hand, in view of a great and ever growing public demand, frequency assignment procedures should strive to ensure the permissible level of interference among radiocommunication services, among stations within each service, as well as efficient utilization of the radio-frequency spectrum and the satellite orbits. For some applications (e.g., broadcasting and mobile services) appropriate frequencies for different sites may be determined in the aggregate in advance and these frequencies are assigned later during creation and expansion of relevant networks, as necessary. Such activity may be referred to as a “frequency-site” planning process. This may be an allotment process in some administrations.

  • Radiocommunications have become an increasingly vital part of the telecommunications infrastructure and consequently economy of a country and economic approaches to national spectrum management are becoming essential. These approaches promote economic, technical, and administrative efficiency, and help ensure that radio services are able to operate on a noninterference basis.

  • This Chapter addresses issues relating to the financing of a national spectrum management program. It gives some information on the use of new tools, based on spectrum economics, to address issues that have arisen in a number of Administrations, mainly in the developed countries, due to the increase in demand for spectrum following the liberalization of telecommunications. The increase in demand creating problems in frequency assignment that many administrations have found difficult to resolve using the traditional spectrum management tools and which, in turn, has generated an interest in the development and use of new spectrum management tools based on the use of spectrum economics. A number of the ideas that are discussed in Report ITU-R SM.2012-2 (Economic aspects of spectrum management) are presented below, to avoid taking the theory contained in that report out of context the following text concentrates on the various fee types and spectrum pricing mechanisms. For a detailed analysis of spectrum economics reference should be made to the Report.

  • When the amount of data is large and the requirements for analytical studies are complex and diverse, automation techniques become a necessity. Automation can also improve the implementation of limited analysis techniques and databases. Computer systems offer the means to store data in a readily retrievable form, to manipulate the data, to produce reports relating to the data and to perform analytical studies.

  • Spectrum utilization efficiency (SUE) is important since the spectrum is a limited resource that has economic and social value, and because demands for spectrum are increasing rapidly in most frequency bands. In recent years, many improved and emerging radio technologies, made possible considerable improvement in the efficient use of the spectrum. The new techniques help in accommodating the growing demands for spectrum allocation and use. The measure of spectrum utilization efficiency is different for different types of systems or services. For example, the calculation of spectrum efficiency for point-to-point systems is different than that for satellite or land mobile systems. Hence the comparison of spectrum efficiency can only be done between similar types of systems and within a specific frequency band or channel. It would also be beneficial to conduct the comparison of spectrum efficiency or utilization of the same system over time to see if there is any improvement in the specific area under study.
