RBS 2207 1 Radio Configurations Introduction The radio configurations described are valid for RBS 2207, equipped with a maximum of three dTRUs/six TRXs per cabinet. The descriptions include basic configurations and site cell configurations. 1.
Radio Configurations RBS 2207 Figure 2 1.2 An example of an RBS 2000 servicing a three-cell site Radio Base Station The Radio Base Station 2000 (RBS 2000) is Ericsson’s second generation of RBSs, developed to meet the GSM specifications for BTSs. 2 3 References 3GPP TS 45:005 Digital cellular telecommunications system (Phase 2+); Radio transmission and reception (3GPP TS 45:005 Release 4).
RBS 2207 Radio Configurations Antenna Reference Point The antenna reference point is the point where the radio signal crosses the RBS border, that is the connector for the antenna feeder. See the figure below. Note: The TMA is inside the RBS border. RBS Antenna TRX Combining system TRX . . .
Radio Configurations RBS 2207 Site Cell Configuration (SCC) The SCC is a geographical concept describing how an area around one RBS site is divided into radio traffic areas. The following types of site are defined: 3.1 Omni-site Radio coverage in one 360 degree sector, that is in one area, using one BTS. 2-sector site Radio coverage in two sectors, that is two distinct areas, using two BTSs. 3-sector site Radio coverage in three sectors, that is three distinct areas, using three BTSs.
RBS 2207 Radio Configurations The radio performance of a configuration is defined at the TX and RX antenna reference points at the RBS border. There is an X close to every reference point in the following figures. The RBS border is not included in the figures. The equivalent output power with SW power boost (TX diversity) configured is the original output power specified for the basic configuration, increased by typically 3 dB (if separate TX antennas are used).

Radio Configurations 6 RBS 2207 Site Cell Configurations (SCC) This section shows SCCs in one RBS. More RBSs can be combined to form larger configurations at a site. The following SCCs are supported by the RBS: 6.1 • Specified basic radio configurations • The RBS with any number of dTRUs within the specified range inserted in the specified position order • CDU-G can exist in earlier versions of RBS 2207 Single Band Configurations This section describes single band configurations for CDU-J.

Radio Configurations 6.3 RBS 2207 Mixing CDU-G and CDU-J Mixing CDU-G and CDU-J within the same cabinet is allowed for all single band and dual band, except for 2x1 CDU-J or CDU-G without hybrid combiner. See Figure 6 on page 9, that is dTRU to 2 x CDU-G or 2 x CDU-J. 6.4 RX Cables CDU-G must be cabled with QMA attenuators or the cables with build-in attenuators. CDU-J must never be cabled with the RX cables with build-in attenuators. It must be cabled without the QMA attenuators. 6.
