6.3 Heat Dissipation
The heat dissipation value given in this section is dependent upon configuration,
equipment and site-specific conditions. The value represents the worst-case
power consumption of a fully equipped RBS. For power consumption during
traffic, see Section 10.2 on page 42, where maximum power consumption
is given.
The maximum heat dissipation from the RBS is described in the table below.

6.4 Acoustic Noise

6.5 Radio Frequency Electromagnetic Exposure
This section provides information on Radio Frequency (RF) Electromagnetic
Field (EMF) exposure from a typical antenna connected to the RBS 2111
Second Generation.
6.5.1 Compliance Boundaries for Electromagnetic Exposure
The compliance boundary defines the minimum separations that must be kept
between the antenna and a person to ensure that the ICNIRP Reference [1]
and FCC Reference [2] Reference [3] RF exposure limits are not exceeded.
Ericsson has performed RF exposure assessments of typical configurations
with the RBS 2111 Second Generation and with three recommended antennas.
The resulting dimensions, in meters, for a compliance boundary for both public
and occupational exposure are shown in Table 11.
The compliance boundary is defined as a cylinder surrounding the antenna,
see Figure 13. A directional antenna is not located at the center of the cylinder.
Instead it is located almost at the edge, facing towards the center of the
cylinder. The distance between the back of the antenna and the cylinder is the
“Distance behind antenna”. The height of the cylinder is the antenna height
plus equal distances above and below the antenna.
