 Austria (2014) Issued since 2012

  • Precautionary target threshold level: < 1000 µW/m2 sum total of all fixed wireless transmitters inside or outside a building
  • Applies not only to cell tower emissions (e.g. GSM, UMTS, LTE, etc.) but any fixed wireless transmitter from 100 kHz (e.g. broadcasting, TV, Wi-Fi, TETRA, ham radio, etc.)
  • Applies to sensitive areas where humans spend more than 4 hours per day (e.g. residences, schools, workplaces)
  • List of scientific studies on nonthermal biological effects
  • RF measurement protocol of average and peak levels (with broadband RF meter or spectrum analyzer)

Limiting the permissible power output (EIRP)

  • Changing the direction of the main beam
  • Adjusting the beam width
  • Changing the antenna gain
  • Changing the beam tilt angle
  • Adjusting the mounting height
