RBS 2206

Ground Vibrations

The RBS 2206 is tested to withstand random vibrations of up to 0.15 m

It is also tested for single shocks up to 40 m/s

. The cabinet is tested for

seismic exposure with a test frequency of 1 – 35 Hz. Maximum test level of the

Required Response Spectrum (RRS) is 50 m/s

within 2 – 5 Hz. The shape of

RRS is defined by the ETSI standard.

Levelling

For cabinet levelling purpose, the floor must be level to within ±3 mm/2000 mm

and the floor gradient be within ±0.1

4.2 Environmental Impact

This section describes the effects that the cabinet has on the environment.

Heat Dissipation

The RBS 2206 generates an average heat load of 1500 W. The exact figure is

dependent upon confguration, equipment and site-specific conditions.

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 2206 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 12.

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.
