RBS 2107
4.3 Compliance Distances for Electromagnetic Exposure
The compliance distance is the minimum separation that should be kept
between the antenna and a person in order to ensure that the ICNIRP RF
exposure limits are not exceeded.
Note: ICNIRP, ‘‘Guidelines for limiting exposure to time-varying electric,
magnetic, and electromagnetic fields (up to 300 GHz)’’, International
Commission on Non-Ionizing Radiation Protection, Health Physics,
vol. 74, no. 4, 1998.
Ericsson has performed a free-space near-field RF exposure assessment of
typical configurations of the RBS 2107 with a recommended antenna. The
resulting dimensions, in metres, for a compliance boundary for both public and
occupational exposure, are shown in Table 4 on page 10.
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 center 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 on page 10 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:
