Ericsson has performed a free-space near-field RF exposure assessment
of typical configurations of the RBS with a recommended antenna. The
resulting dimensions, in metres, for a compliance boundary for both public and
occupational exposure are shown in Table 4.
The compliance boundary is defined as a cylinder around the antenna, see
figure below. The antenna is not located at the centre of the cylinder. Instead
it is located almost at the edge, facing towards the centre of the cylinder.
The distance between the antenna’s rear and the edge of the cylinder is the
"Distance behind antenna". The height of the cylinder is the antenna height
plus equal distances above and below the antenna. The cylinder shape
overestimates the compliance distances right beside the antenna.

Note: Table 4 shows an example for a typical antenna. As the antenna field
distributions will differ, complete calculations or measurements may
be necessary in order to establish the compliance boundary for other
configurations chosen by the customer. For further information on
calculation methods, see Radio Frequency Electromagnetic Fields.
