  • Page 3: Product Overview

    RBS 2207 Product Overview The RBS 2207 is a medium capacity indoor base station. It is used for indoor applications, with up to three double Transceiver Units (dTRU). The RBS 2207 is designed to be transported as a fully-assembled cabinet to the site. All interior units are easily accessible from the front of the cabinet, which means that the cabinets can be mounted side by side with their backs against a wall.

  • Page 4: Optional Equipment

    Distribution Frame (DF) with OVP • TMA-CM • Transmission Adapter (TA) • GPS receiver Dimensions The following section describes the measurements of the RBS 2207. Table 1 Weight Unit Weight RBS cabinet (fully equipped including 180 kg (397 lbs.) base frame) Base frame 8 kg (18 lbs.)
  • Page 5 Min.250 P010922A Figure 1 RBS 2207, free space above the cabinet The recommended distance between the cabinet and cable ladder is 250 mm. A shorter distance makes it difficult to exchange fans and may restrict the air flow. A space of 300 mm is recommended above the cable ladder, in order to simplify the cable installation work.
  • Page 6 RBS 2207 Layout for RBS Cabinets a=130 Unit of measurement: mm P007781A Figure 2 Floor layout and space requirements The RBS cabinets and battery back-up system (BBS) racks are mounted on the floor, and may be positioned against a wall, back to back, or free standing without contact with other cabinets.

    The base frame can be used as a template to mark new holes. If an RBS 2202 or an RBS 2206 is being replaced by an RBS 2207, the holes for the old cabinet can be used for the new cabinet.

  • Page 8: Environmental Impact

    5.5 days in a three-year period. Ground Vibrations The RBS 2207 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.
  • Page 9 74, no. 4, 1998. Ericsson has performed a free-space near-field RF exposure assessment of typical configurations of RBS 2207 with a recommended antenna. The resulting dimensions, in meter, for a compliance boundary for both public and occupational exposure are shown in Table 4.
  • Page 10 The maximum power fed to the antenna, as a function of the number of transceiver units (TRUs) per antenna and maximum power (including tolerances and transmission loss) per TRU, for RBS 2207, are given in Table 6. 10 (24) EN/LZT 720 0134 Uen R3A...

  • Page 11: Materials

    A high level of availability is achieved using strict functional modularity with a system of standardized units. A failed unit can easily be replaced by a new one. The RBS 2207 cabinet contains the radio equipment, power supply and the climate equipment (fans). All required transmission equipment and battery back-up must be housed outside the cabinet.

  • Page 12: Standard Hardware Units

    The CDU distributes the received signal to several transceivers. The CDU supports EDGE. Both CDU-G and CDU-J is used in the RBS 2207. CDU-G and CDU-J can be configured either for high capacity or for high coverage. It is a combiner that can be used for synthesizer hopping.
  • Page 13 RBS 2207 CDU uses the hybrid combiner in the dTRU. To achieve coverage, the CDU is used in a configuration when the hybrid combiner in the dTRU is not used. Number of units: 1 - 3 DCCU - DC Connection Unit The DCCU distributes the incoming DC power supply voltages to the PSUs.

  • Page 18: Power System

    The power system of the RBS 2207 depends on the choice of power supply and may include a number of units outside the RBS. The RBS 2207 can be connected either to AC mains supply voltage or to DC supply voltage.
