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

  • 16. 16ContentContent• Introduction• Base station compliance– Does base station comply with relevantstandard?• EMF Measurements in public areas– Public risk perception• Summary
  • 17. 17EMF MeasurementsEMF Measurements• Why measure EMF levels in in public areas aroundcellular base stations?– Public concern– Normally well outside the exclusion zone
  • 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. 19EMF MeasurementsEMF Measurements• Automated
  • 20. 20EMF MeasurementsEMF Measurements• Some positions
  • 21. 21EMF MeasurementsEMF Measurements• Some positions
  • 22. 22EMF MeasurementsEMF Measurements• Results (77 000 measurements)
  • 23. 23Longer duration measurementsLonger duration measurements• Spectrum analyzer spot measurements preferred
