Role of ITU-T & ITU-R

1. ITU-T Workshop on Delivering Good Quality Telecommunication Service in a Safe Environment in Africa(Nairobi, Kenya, 26 July – 27 July 2010 ) Role of ITU-T & ITU-R Ahmed ZEDDAM, ITU-T SG5 Chair France Telecom Orange

2. Outline • To introduce the ITU and the objectives of the ITU-R and ITU-T • International Spectrum Management • Radiocommunication Standardization • Recommendations (“Standards”) • Environmental issues in ITU-R • Studies relating to RF emissions • EM radiation and Health

3. International Telecommunication Union 191 Member States 572 Sector Members 149 Associates Regional/National SDO’s e.g. ETSI, IEC UN bodies e.g. WHO, WMO Regional Frequency Management e.g. CEPT Industry fora e.g. WiMAX

4. ITU: Committed to connecting the world ITU-T Telecommunication standardization- Network functionality, NGN, tariffs, Environment & Climate change ITU-D Assisting implementation and operation of telecommunications in developing countries ITU-R International Spectrum Management and Radiocommunication Standardization

5. ITU-R mission “To ensure rational, equitable, efficient and economical use of the radio-frequency spectrum by all radiocommunication services, including those using satellite orbits, and to carry out studies and adopt recommendations (standards) on radiocommunication matters.” International regulatory framework : • to facilitate equitable access to and rational use of the natural resources of the radio-frequency spectrum and the geostationary-satellite orbit; • to ensure the availability and protection from harmful interference of the frequencies provided for distress and safety purposes; • to assist in the prevention and resolution of cases of harmful interference between the radio services of different administrations; • to facilitate the efficient and effective operation of all radiocommunication services; • to provide for and, where necessary, regulate new applications of radiocommunication technology.

6. ITU-R Study Groups • SG 1: Spectrum management • SG 3: Radiowave propagation • SG 4: Satellite services • SG 5: Terrestrial services • SG 6: Broadcasting service • SG 7: Science services

7. Environmental issues in ITU-R • Emergency Communications • radiocommunication services and systems for prediction, detection, alerting, damage assessment and relief • meteorological satellite services • fixed (terrestrial and satellite), mobile (terrestrial and satellite), amateur and broadcasting services • Climate and Environmental Monitoring • remote sensing from satellites • meteorological instrumentation, e.g. radiosondes • relaying of climate and weather information • Spectrum Management • economic use of radio spectrum (reduced interference and spectral pollution) • allocation and protection of frequencies for vital services • reduced number and power of TXs, e.g. analogue to digital broadcasting • calculation, measurement and monitoring of electromagnetic fields

8. ITU-R studies on E.M. Radiation (1) E.M. Emissions • ITU-R Study Group 1 • Unwanted emissions • spurious and out-of-band domains • emission limits (e.g. for ISM equipment) • Protection of sensitive services (e.g. passive sensors, RA) • Signal properties, e.g. spectra and bandwidth of emissions, emission types Such information provides fundamental background to the nature of EM radiation

9. ITU-R studies on E.M. Radiation (2) Measurement, Monitoring and Calculation • ITU-R Study Groups 1 and 6 • Measurement of field strength and bandwidth (applicable to all radiocommunication services) • ITU-R Handbooks on “Spectrum Monitoring” and “National Spectrum Management” • Recommendation ITU-R SM.378-7 and SM.1708 on field strength measurement • Fields from broadcasting stations • Recommendation ITU-R BS.1698 Evaluation of E.M fields for assessing exposure

10. Role of ITU concerningHealth Effects from EM radiation Limited • but ITU Recommendations on • wireless technologies • radio frequency emissions, (measurement, calculation, propagation) can be used for evaluating radiation levels and for helping to identify a hazardous situation.

11. Recommendation ITU-R BS.1698 “Evaluating fields from terrestrial broadcasting systems operating in any frequency band for assessing exposure to non-ionizing radiation” • provides basis for deriving and estimating the e.m. radiation from a broadcasting station at a particular distance from a transmitter site • by comparison with reference levels (e.g. ICNIRP), responsible organizations can then take measures to protect humans from undesirable exposure to harmful radiation

12. Recommendation ITU-R BS.1698 • Calculation methods (analytical and numerical) • estimate field to see whether measurements are required • Measurement methods • function of distance • function of frequency • instrumentation • Precautions • Examples of calculated fields and comparison with measurements

13. ITU-T Recommendations related to human exposure to E.M. fields  Next presentation

14. Conclusion • Objectives of ITU-R • international spectrum management • radiocommunication standardization • Environmental issues • Studies on e.m. emissions, including calculation and measurement methods • Activities relating to e.m. exposure assessment for which Recommendations can be used to identify potentially hazardous situations and to comply with exposure limits
