Radio Base Station
Ground Vibrations
The RBS 2206 is tested to withstand random vibrations of up to 0.2 m²/s². It is
also tested for single shocks up to 40 m/s². 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/s² 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 an antenna and a person to ensure that RF exposure limits are not
exceeded.
Ericsson has performed a 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 general 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 in 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 a certain distance above and below the antenna.
