Exposure at Ground Level
Since the antenna installation height above ground level in the typical system configuration (20 m) is
larger than either of the compliance distances determined in Exposure in Front of the Antenna on page
158, the EME exposure at ground level is always compliant with the exposure limits defined in the
ICNIRP guidelines.
Compliance Boundary Description
Based on the analysis in EME Exposure Evaluation on page 158, the compliance boundaries for
occupational and general public exposure are defined as cylinders enclosing the antenna (see Figure
102: Compliance boundary for general public (GP) and occupational (OCC) exposure on page 159),
extending 75 cm (one wavelength) above and below the physical antenna, with radii:
Occupational exposure:
General Public exposure:

Product Put In Service
Some regulations require that additional exposure assessments be performed when putting the
product in service, to account for antenna site-specific circumstances such as the environment
(e.g. electromagnetic scatterers) and other antennas. In such cases, certain standards [7]–[10] may
need to be considered to determine the most suitable compliance assessment methodology.
