  1. 1. ITU“Workshop on Human Exposure toElectromagnetic Fields”Base Station ComplianceMarnus van WykEMSS Consulting, South AfricaTurin, Italy9 May 2013
  2. 2. 2ContentContent• Introduction• Base station compliance– Does base station comply with relevantstandard?• EMF Measurements in public areas– Public risk perception• Summary
  3. 3. 3ContentContent• Introduction• Base station compliance– Does base station comply with relevantstandard?• EMF Measurements in public areas– Public risk perception• Summary
  4. 4. 4IntroductionIntroduction• Various standards / guidelines (ICNIRP, Italy)• Apply to base stations• Balance effort with risk• Risk communication / public perception
  5. 5. 5ContentContent• Introduction• Base station compliance– Does base station comply with relevantstandard?• EMF Measurements in public areas– Public risk perception• Summary
  6. 6. 6Base station complianceBase station complianceSteps Determine “exclusion zone”(IEC 62232) Assess zone accessibility Ensure sufficient safety measures in place(access control, signs, training, etc) Certification
  7. 7. 7Base station complianceBase station complianceSteps Determine “exclusion zone”(IEC 62232) Assess zone accessibility Ensure sufficient safety measures in place(access control, signs, training, etc) Certification
  8. 8. Exclusion zone and accessibilityExclusion zone and accessibility• Where are the exclusion zones and how accessible arethese zones?• Techniques– Generic rules– Computer simulation– Measurement
  9. 9. Exclusion zone and accessibilityExclusion zone and accessibility• Generic rules– Efficiently process many sites where zones are not easilyaccessible
  10. 10. Exclusion zone and accessibilityExclusion zone and accessibility• Computer simulation
  11. 11. Exclusion zone and accessibilityExclusion zone and accessibility• Measurement

  16. 16. 16ContentContent• Introduction• Base station compliance– Does base station comply with relevantstandard?• EMF Measurements in public areas– Public risk perception• Summary
  17. 17. 17EMF MeasurementsEMF Measurements• Why measure EMF levels in in public areas aroundcellular base stations?– Public concern– Normally well outside the exclusion zone
  18. 18. 18EMF MeasurementsEMF Measurements• Use Narda portable spectrum analyzer• Follow established measurement procedure (IEC62232, CENELEC, etc)• Positions– Publicly accessible positions– Points of local maximum exposure– Points of specific interest– Typically 6-10 points per site
  19. 19. 19EMF MeasurementsEMF Measurements• Automated
  20. 20. 20EMF MeasurementsEMF Measurements• Some positions
  21. 21. 21EMF MeasurementsEMF Measurements• Some positions
  22. 22. 22EMF MeasurementsEMF Measurements• Results (77 000 measurements)
  23. 23. 23Longer duration measurementsLonger duration measurements• Spectrum analyzer spot measurements preferred
  24. 24. 24ContentContent• Introduction• Base station compliance– Does base station comply with relevantstandard?• EMF Measurements in public areas– Public risk perception• Summary
