2.1     RATIONALE FOR ASSESSMENT OF THE RF EXPOSURE


        The aim of the assessment report is to evaluate the compliance boundary for a set of given input
        power(s) according to the basic restrictions (directly or indirectly via compliance with reference
        levels) related to human exposure to radio frequency electromagnetic fields.
        The chosen assessment method to establish the compliance boundary in the far-field region is the
        reference method as defined in EN50383:2010 Clause 5.2; E-field or H-field calculation. The
        method of calculation used is defined in EN50383:2010; Clause 8.2.2, 8.2.3 and 8.2.4.
        The calculated values have been compared with limits provided in the ICNIRP guidelines.
        Calculations can be made in three separate regions, based on distance from the antenna. These
        are called:

        - far-field region,
        - radiating near-field region,
        - reactive near-field region.
        The theory that defines these regions is given in EN50383:2010 Annex A.

        Far-field region

        As shown in EN50383 Annex A, the far-field calculations are accurate when the distance, r, from
        an antenna of length D to a point of investigation is greater than

              2D 2
         r
                  
        Where, r is the distance from the antenna to the point of investigation.

        Radiating near-field region

        The radiating near-field region of an antenna of length D as shown in EN50383 Annex A, this
        region is defined by

                     2D 2
             r 
         4             
        Reactive near-field region

        The reactive near-field region of an antenna as shown in EN50383 Annex A, this region is defined
        by

              
         r
              4
        Where, r is the distance from the antenna to the point of investigation.
        Recommend λ/4 as the boundary between the radiated near-field and reactive near-field for RF
        exposure compliance assessment.
