5. Spectrum Management • Is a combination of administrative and technical procedures to ensure the efficient operation of radio communications without causing Interference • Ensures interference-free access to as many users and as many uses as possible often provides an economic return to the governments. • International – governance of spectrum use on a global basis is a core responsibility of the International Telecommunication Union (ITU) • ITU Radio Regulations, Article 5 - Table of Frequency Allocations establishes a basis for developing a national frequency allocation table.

6. Purpose of Spectrum Management • Spectrum has to be managed to ensure its rational, equitable, efficient and economical use by all radiocommunication services and users, taking into account that: • Interference is caused between radiocommunications systems unless sufficient isolation from each other is provided: in Frequency, Distance or Time domains • Radio spectrum is a finite resource in terms of instant capacity, although it is inexhaustible when used over time. • New applications mean ever growing demand for new spectrum access opportunities. For physical/technical reasons, some parts of the spectrum have greater demand, e.g. VHF/UHF bands due to better propagation conditions • Ensure spectrum use is well coordinated between various users within the same and neighboring countries.

8. Spectrum as Economic Resource • It is interesting to compare spectrum to other natural recourses such as land, oil, and water. www.ictregulationtoolkit.org

9. As a resource, the spectrum has both technical and economic • dimensions • Economically, efficient: Allocating and assigning spectrum to its most economically valuable use • Technically, efficient : use of spectrum, at a basic level, implies the fullest possible use of all available spectrum. Two measures of technical efficiency are occupancy and data rate www.ictregulationtoolkit.org

10. Spectrum Management Activates

11. Spectrum management embodies four main areas of activity • Spectrum planning: provide direction and cohesion in support of policy formulation, and support future steps to achieve optimal spectrum use. Major trends and developments in technology and the needs of both current and future users of the frequency spectrum should be closely monitored and mapped. • Spectrum authorization/licensing: Involves assigning specific frequencies to users, allotting certain frequency bands or sub-bands to specific users under certain specified conditions and in accordance with the national and international table of frequency allocations. • Spectrum engineering: Involves the development of electromagnetic compatibility standards for equipment that emits or is susceptible to radio frequencies. • Spectrum monitoring and compliance: Involves the monitoring of the use of the radio spectrum and the implementation of measures to control unauthorized use

13. Spectrum Management Framework

14. International Framework The governance of spectrum use on a global basis is a core responsibility of the International Telecommunication Union ITU and, in particular, its Radio communication SectorITU-R , The mission of the ITU-R sector is, inter alia, to ensure rational, equitable, efficient and economical use of the radio frequency spectrum by all radio communication services, including those using satellite orbits and to carry out studies and adopt recommendations on radio communication matters.

19. Radio Regulations • The first International Radiotelegraph Convention was signed in Berlin in 1906. The annex (12-page ) to this Convention contained the world’s first set of service regulations on the use of radio.  • Today, known as the Radio Regulations (over 2000 pages), the legal and technical provisions of this document have since been expanded and revised by numerous radio conferences in order to keep in step with the ever-expanding use of radio.  • The Radio Regulations have the status of an international treaty and are binding on ITU Member States.

20. What are the RR? • Principal instrument of the international radio regulatory arrangement based on the use of following concepts: • Frequency block allocations intended for use by defined radio services (Table of Frequency Allocations as contained in AR 5) • Generally provides common frequency allocations to mutually compatible services operating with similar technical characteristics in specific parts of the spectrum • Stable planning environment for administrations, for equipment manufacturers and for users

21. Purpose of RR • To ensure interference-free operations of radiocommunication systems; • To provide ITU Member States with: • Equitable access to the radio spectrum, and • Orbital positions for space stations • Include a Table of Frequency Allocations for the various radio services (inter alia radio broadcasting, television, radio astronomy, navigation aids, point-to-point service, maritime mobile, amateur).  • Include allotment and frequency plans (Appendices) • Deal with ways of avoiding harmful interference and contain various other provisions, such as those relating to the qualifications required for station operators, and the nature and contents of essential documents for international radio service

22. Maintenance of RR • Written and updated by ITU Member States through a procedure of negotiation based on the principles of multilateral cooperation and agreement.  • At the heart of this process are ITU’s World Radiocommunication Conferences (WRCs), normally take place every three to four years: • address issues related to all aspects of radiocommunication services including the revision of the Radio Regulations.  • Regional and national preparatory work done in the period between conferences contributes to an important harmonization of national positions, and most decisions at WRCs are subsequently taken by consensus.

23. Volumes of the RR • Volume 1: Articles • Volume 2: Appendices • Volume 3: Resolutions • Volume 4:Recommendations incorporated by reference

24. Article 5: Frequency allocations • 5.2:Region and areas: delimitation

25. Article 5-Section III: Frequency allocation 220-335.4 MHz

27. General description of SMS4DC • SMS4DC is software designed by ITU based on ITU recommendations • 2007: SMS4DC Version 1.0 • 2008: SMS4DC Version 2.0 (Addition of Digital TV planning tools (GE06)) • 2009: SMS4DC Version 3.0 (Addition of Google Earth and monitoring interface) • 2012: SMS4DC Version 4.0 (link to ESMERALDA monitoring software of Thales and additional enhancements to the Version 3 of the software) • Developed to assist the administrations of developing countries to undertake their spectrum management responsibilities more effectively; • SMS4DC covers terrestrial fixed, mobile, sound and television broadcasting services in the bands above 30 MHz, including GE-06 as well as frequency coordination of Earth stations

31. Security Mechanisms in SMS4DC • In SMS4DC each user is granted permission to access only those features • relevant to his/her tasks and responsibilities. The following access levels have • been implemented in the SMS4DC software: • Data entry (Licensing and Billing): Privileged to read/write licensingand billing data, • Engineers: Privileged to read/write technical data, No read access toadministrative data, • Senior operator: Privileged to read/write all data, as well as to manageuser IDs and passwords, audit trail and to configure and enjoy anyfeatures of software, • Supervisor: The same as senior operator, • Licensing: The same as data entry, • Read-only: Privileged to use software without permission to edit or addany data,
