RBS 2206                                                                         Antenna Configurations




1                  Introduction
                   The various configurations available for the RBS 2206 are described according
                   to the following example:




                                                 3 x 2 CDU-F
                                   Number                               Type of CDU
                                   of cells
                                   Number
                                   of TRX/cell

                                                                                               P008245B


                   Figure 1   CDU Configuration Key

                   In the example above, the cabinet is configured for three cells, each using two
                   Transceivers (TRX). The total number of TRXs is thus six in this case. The
                   Combining and Distribution Unit (CDU) is of the type CDU-F.

                   Note:   If a Tower Mounted Amplifier (TMA) is used, then the bias injectors
                           must be installed.


2                  Antenna Connection Field
                   This section describes the antenna connection fields in the RBS 2206.

                   Antenna jumpers are connected at the connection field shown in the figure
                   below. The example shown, in this case, is for CDU-G.




                                                              CDU-G   CDU-G    CDU-G




                                                                                               P011001A

EN/LZT 720 0320 Uen R3A                                                                           3 (24)


Antenna Configurations                                                                                          RBS 2206




                         The RF cables between each CDU and its associated TRansceiver Units (TRU)
                         are standardised and do not normally change.

                         Certain configurations require the use of an Antenna Sharing Unit (ASU). In
                         these cases, the signal is shared between RBSs through the antenna sharing
                         connection fields

                         The figure below provides an overview of the antenna sharing connectors and
                         the cabling from the ASU.

1                  Introduction
                   The various configurations available for cabinets are described according to
                   the following example:




                   Figure 1   CDU configuration key

                   In the example above, the cabinet is configured for three cells, each using two
                   TRXs. The total number of TRXs is thus six in this case. The CDU is type
                   CDU-J.

                   Note:   If a tower mounted amplifier (TMA) is used the bias injectors must
                           be installed.

2                  CDU-J Antenna Connections
                   The antenna connectors are located on the top of the CDU, see figures below.

                         This section shows different configurations for CDU-J. It can exist CDU-G in the
                         RBS 2207 but it is configured the same way as CDU-J.

                         Note:   In the figures and tables that follow, only cabinets that are fully-equipped
                                 are shown. Configurations consisting of part of the fully-equipped
                                 cabinet can also be extracted from the following figures and tables.

                         See Figure 1 on page 3 for a description of the column headers in the tables
                         below.
