Introduction 1 Introduction The RBS 2206, a member of the RBS 2000 family, is a 12-Transceiver (TRX) radio base station for indoor applications. This cabinet covers the same floor area as the RBS 2202, its predecessor, and has double capacity. The RBS 2206 V2 is a variant of the RBS 2206, that has a new Electromagnetic Compatibility (EMC) topology and several new Replaceable Units (RU). RBS 2206 RBS 2206 V2 P016586A 1.
RBS Product Description 2 Product Overview The RBS 2206 is a high-capacity indoor base station. It is used for indoor applications, with up to six double Transceiver Units (dTRU). The RBS 2206 is designed to be transported as a fully assembled cabinet to the site. All units in the cabinet 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. 2.

RBS Product Description Ground Vibrations The RBS is designed to withstand random vibrations of up to 0.15 m2/s3, and its resistance to single shocks of up to 40 m/s2 and seismic activity at test frequencies of 1–35 Hz is tested. The maximum test level of the Required Response Spectrum (RRS) is 50 m/s2 within 2–5 Hz. The shape of the RRS is defined by the relevant 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 .
Environment Figure 6 Note: Compliance Boundary Cylinder Table 4 shows an example for a typical antenna. As the antenna field distributions will differ, complete calculations or measurements may be necessary in order to establish the compliance boundary for other configurations chosen by the customer. For further information on calculation methods, see Radio Frequency Electromagnetic Fields.

Hardware Units • Recycling Package Material The package material is recyclable. 6 Hardware Units 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 cabinet contains the radio equipment, power supply and the climate equipment (fans). All required transmission equipment and battery backup must be housed outside the cabinet. Outside equipment is listed under optional units.

Number of units: 0–1. CDU The Combining and Distribution Unit (CDU) is the interface between the transceivers and the antenna system.
Hardware Units CXU-10 This variant of the Configuration Switch Unit (CXU) cross-connects the CDU and the dTRU in the receiver path. The CXU makes it possible to expand or reconfigure a cabinet without moving or replacing any Receiver (RX) cables. The RX inputs/outputs on the dTRU and the CDU are positioned so that they minimize the number of cable types needed to connect the CXU with the dTRUs and the CDUs. The CXU is configured by means of software.
RBS Product Description IDM-01 The Internal Distribution Module (IDM) is a panel for distributing the internal +24 V DC power to the various units. Each distribution circuit in the cabinet is connected to a circuit breaker in the IDM. Number of units: 1 PSU The Power Supply Unit (PSU) are available in two versions, PSU AC for connection to AC mains, or PSU DC for connection to 048 or 060 V DC power supply.

Number of units: 0–1. CDU The Combining and Distribution Unit (CDU) is the interface between the transceivers and the antenna system. All signals are filtered before transmission and after reception by means of bandpass filters.
RBS Product Description • CDU-K can be configured for large capacity or large coverage, with 12 transceivers uncombined in one cabinet. It also allows dual band configurations with 6 transceivers for each frequency. Configurations with 4-way receiver diversity in three sectors can also be built in one cabinet. Number of units: 1–6 CXU-10 This variant of Configuration Switch Unit (CXU) cross-connects the CDU and the dTRU in the receiver path.
Hardware Units external interface for transmission, GPS Synchronization (GPS), ESB, and alarms. Four ports can handle both 2048 kbps (E1) and 1544 kbps (T1) transmission. The DXU supports EDGE. The fan control is integrated in the DXU and controls the fans in the cooling system by regulating fan speed. Number of units: 1 IDM-11 This variant of the Internal Distribution Module (IDM) is a panel for distributing the internal +24 V DC power to the various units.
RBS Product Description BBS The RBS can be provided with a Battery Backup System (BBS) from an external cabinet. ddTMA The Dual-Duplex Tower-Mounted Amplifier (ddTMA) is installed on a mast, close to the antenna. The ddTMA improves receiver sensitivity and saves feeder cables by duplexing RX and TX signals to the same cable. DXX A one- or two-card Digital Cross-Connect (DXX) plug-in unit can be installed in a space for optional equipment (OXU) on the PSU/DXU subrack in the RBS 2206 (not RBS 2206 V2).
Hardware Units 19-inch Space for Optional Equipment A 2U-high 19-inch space for optional equipment, for which the RBS provides climate control. OXU The following space for optional expansion (OXU) is available: • Four positions (RBS 2206) or two positions (RBS 2206 V2) in the DXU/PSU subrack • A 1U-high 19-inch OXU position is available between the CXU and the dTRU subrack. RUs which typically are located in the OXU slots include the DXX and the TMA-CM.
