  1. ITU Workshop on “Tackling climate change and Specific Absorption Rate (SAR) Measurement” (Cotonou, Benin, 19 July 2012) Overview of ITU-T/SG 5 activities Ahmed ZEDDAM, ITU-T SG5 Chair France Telecom Orange

  2. Outline • Environmental issues and Studies relating to EM radiation and Health in ITU-R • Mandate and Objectives of ITU-T/SG5 • Human exposure to electromagnetic fields (EMFs) due to radio systems and mobile equipment : ITU-T/SG5/Q3 • Recommendations under the scope of Q3 • Resolution 72 of ITU-T • ITU-T/SG5 Regional Group for Africa • Conclusion

  3. International Telecommunication Union 193 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 standardizationSGs:- 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. 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 (SG1 and SG6) Fields from broadcasting stations :RecommendationITU-R BS.1698 • Evaluation of E.M fields for assessing exposure  ITU-R Recommendations can be used for evaluating radiation levels and for helping to identify a hazardous situation

  6. Structure of ITU-T SG5 ITU-T SG5 “Environment and Climate Change ” Q.14 Terminology WP3/5 ICT and climate change WP2/5 Electromagnetic fields: emission, immunity and human exposure WP1/5 Damage prevention and safety 7 Questions 7 Questions 7 Questions Question 3/5 Human exposure to EMFs Question 5/5 & 6/5 Lightning protection & Earthing and Bonding Question 18/5 Methodologies

  7. SG 5 Mandate Study Group 5 is responsible for : • Studies relating to protection of telecommunication networks and equipment from interference and lightning; • Studies relating to electromagnetic compatibility (EMC), to safety and to health effects connected with electromagnetic fields produced by telecommunication installations and devices, including cellular phones ; • Studies on the existing copper network outside plant and related indoor installations. • Studies on ICT & Climate Change

  8. Objective • Study environmental issues to define PROTECTIVE MEASURES, INSTALLATION TECHNIQUES & METHODOLOGIES by means : • Recommendations: K & L-series • Directives • Handbooks • Lightning Handbook, Earthing Handbook • Measuring Handbook, Mitigation Handbook • Handbooks on ICT & Climate change • Recommendations for limiting the RISK of : • Damages to telecommunication installation and equipment • Disturbances to and from telecommunication systems • Injury to people : Safety &Human exposure to e.m. fields (EMF) produced by telecommunication installations (Q3/5) • Recommendationson : • Methodologies for evaluating the ICT effects on climate change, • Energy efficiency of the power feeding systems • Methodologies to reduce environmental effects such as recycling

  9. ITU-T SG5 Question 3/5 "Human exposure to electromagnetic fields (EMFs) due to radio systems and mobile equipment" Rapporteur: Fryderyk Lewicki (Poland) Associate Rapporteur: Tariq Alamri (Saudi Arabia)

  10. Main tasks & Responsibility • Assignment of the exposure limits considered as safe for people : • Standards for evaluation and measurement of exposure levels : • Best practices, Implementation and guidance on telecommunication installations : • Compliance with ICNIRP exposure limits WHO, ICNIRP, National medical authorities IEC, CENELEC, COST 281, National standardization committees ITU-T SG5

  11. ITU-T Study Group 5 Question 3/5 :Human exposure to electromagnetic fields (EMF) due to radio systems and mobile equipment Guidance for the telecommunication sector  Collaboration with other standardization bodies (IEC, CENELEC, WHO) in order to avoid duplication of work Support to developing countries – Resolution 72

  12. ITU-T Recommendations related to human exposure to E.M. fields • ITU-T Recommendations K.52 and K.61 • Guidance on complying with safety limits for human exposure to e.m. fields from a telecommunication installation or mobile handset • Adopts a step-by-step approach to determine an exceedance zone (within which field exceeds reference limits) • Compliance achieved if exceedance zone is not accessible to personnel under normal conditions • ITU-T Recommendation K.70 • Mitigation Techniques to limit human exposure to EM fields in the vicinity of radiocommunication stations • Software provided that implements methodology: EMF- estimator

  13. ITU-T Recommendations related to human exposure to E.M. fields • ITU-T Recommendations K.83: “Monitoring of EMF levels” • Gives guidance on how to make long-term measurement for monitoring of electromagnetic fields (EMF) in the selected areas that are under public concern in order to show that EMF are under control and under the limits. • The purpose of Recommendation K.83 is to provide for the general public clear and easily available data concerning electromagnetic field levels in the form of results of continuous measurement. • The balance between costs and • accuracy is very important

  14. ITU-T Recommendation K.91 • Guidance on how to handle the problem of the human exposure assessment in order to help the user to apply existing standards • Gives guidance on how to assess and monitor human exposure to (EMF) in the areas with surrounding radiocommunication installations based on existing exposure and compliance standards in the frequency range of 9 kHz to 300 GHz. • Oriented to the examination of the area accessible to people in the real environment of currently operated services with many different sources of RF EMF • Gives references to standards and recommendations related to EMF compliance of products. • A software is provided in order to help in the calculation of the uncertainty • Recommendation ITU-T K.91 developped with Resolution 72 taken into account "Guidance for assessment, evaluation and monitoring of human exposure to radio frequency electromagnetic fields”

  15. ITU-T SG5 Regional Group for Africa • Created by SG5 (In accordance with Resolution 72), in May 2009 • Objectives : • Encourage national authorities, operators and consumers from developing countries to work together and better contribute to ITU-T activities on the achievement of EMC in telecommunication installations as well as on EMF and human health • To enhance the collaboration on all activities related to “Climate change” in conformity with SG5 extended mandate • Contact: tsbsg5rgafr@itu.int

  16. Conclusion • Presentation of the objectives of ITU-R and ITU-T with regard to studies on EMF • Activities relating to EMF exposure assessment for which Recommendations can be used to identify potentially hazardous situations and to comply with exposure limits • ITU-T SG5 takes part in standardization by preparing Recommendations, which give appropriate guidance for administrations and telecommunication operators and supports developing countries (Resolution 72) • ITU activity is complementary to the works carried out in other international standardization bodies involved in this subject - there is no duplication of work • Objectives of the SG5 Regional Group for Africa

  17. All the SG5 activities are reported in our web site: http://www.itu.int/ITU-/studygroups/com05/index.asp The vast majority of all Recommendations are available in electronic (PDF) form free of charge • For a complete picture of SG 5 Publications: Guideto the use of ITU-TSG5 publications • The document is aimed at telecommunications equipment designers and operators and will also be very helpful for users in developing countries
