  • Page 51 Radio Base Station Footprint The footprint of the RBS 2106 is 1300 mm wide and 710 mm deep. Note that the door, which is 242 mm deep, is not included in the footprint, as it does not reach down to the ground. The installation frame of the RBS 2106 has the same bottom holing pattern as that of the RBS 2102.
  • Page 52 Environmental Impact This section describes the effects that the cabinet has on the environment. Heat Dissipation The RBS 2106 generates an average heat load of 3000 W. The exact figure is dependent upon configuration, equipment and site-specific conditions. Acoustic Dispersion The cabinet noise dispersion for an RBS 2106 with Combined Climate Unit is shown in the two figures below.

  • Page 54 Ericsson has performed a 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 4.
  • Page 55 The maximum power fed to the antenna, as a function of the number of transceiver units (TRUs) per antenna and the maximum power (including tolerances and transmission loss) per TRU, for RBS 2106 at 900 MHz and 1800 MHz, are given in Table 6.

ACCU – AC Connection Unit The ACCU connects, disconnects, and distributes the incoming AC power supply to the PSUs and the climate unit.
  • Page 58 All signals are filtered before transmission and after reception by means of bandpass filters. The CDU allows several dTRUs to share antennas. There are a maximum of three CDUs in one RBS 2106. The CDU combines transmitted signals from several transceivers, and distributes the received signal to several transceivers.
  • Page 59 RBS 2106 Radio Base Station DF – Distribution Frame The Distribution Frame (DF) is a connection and overvoltage protection (OVP) device for external alarms and PCM links. The DF protects equipment inside the RBS from overvoltage and overcurrent which may occur in external lines.
  • Page 60 Antenna sharing is part of co-siting, that is, using another cabinet together with a GSM RBS 2106 cabinet in the same sector. The ASU allows a TDMA (or other) cabinet and a GSM RBS 2106 cabinet to share RX antennas.
  • Page 61 RBS 2106 Radio Base Station DC/DC Converter The DC/DC converter can supply -48 V DC power to transmission equipment in the TM compartment. It converts +24 V DC to -48 V DC. Number of units: 0 – 2 ddTMA The ddTMA is to be mast-mounted and placed close to the antenna. It improves the receiver sensitivity.

  • Page 382 An indicator on the front panel is illuminated for each TMA in operational mode. Whether an indicator is illuminated depends also on the actual configuration, see Chapter Radio Configurations, RBS 2106 and RBS 2206. If the TMA or the feeder cable short-circuites, the TMA-CM limits the current to 500 mA.
