RBS Product Description
5.3 Compliance Distances for Electromagnetic Exposure
The compliance distance is the minimum separation that must be kept between
the antenna and a person to ensure that the ICNIRP Radio Frequency (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 2106 with a recommended antenna. The
resulting dimensions, in metres, for a compliance boundary for both public and
occupational exposure, are shown in
Table 17.
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
so-called 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.
