Radio Base Station 4.3 RBS 2106 Compliance Distances for Electromagnetic Exposure The compliance distance is the minimum separation that should be kept between an antenna and a person to ensure that RF exposure limits are not exceeded. 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.

ACCU – AC Connection Unit The ACCU connects, disconnects, and distributes the incoming AC power supply to the PSUs and the climate unit.
Radio Base Station RBS 2106 Climate Unit The climate unit maintains the internal temperature and humidity inside the cabinet. The climate unit is mounted in the door of the cabinet. Two types of climate unit are available: • Combined Climate Unit. This unit provides both heating and refrigeration. • Air-to-Air Heat Exchanger climate unit. This provides heating, and cooling through forced convection.
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. Examples of equipment requiring OVP include transmission lines, ESBs, external alarms and positioning devices (GPS and LMU). Number of units: 1 DXU-21 – Distribution Switch Unit The DXU-21 is the central control unit for the RBS.

RBS 2206 5 Radio Base Station Hardware Units A high level of availability is achieved using strict functional modularity with a system of standardised units. A failed unit can easily be replaced by a new one. It is possible to add up to three new units in the PSU/DXU magazine. The RBS 2206 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.
Radio Base Station RBS 2206 CDU – Combining and Distribution Unit The 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. The CDU allows several dTRUs to share antennas. There are a maximum of three CDUs in one RBS 2206. The CDU combines transmitted signals from several transceivers, and distributes the received signal to several transceivers. The CDU is hardwareprepared to support EDGE.
RBS 2206 Radio Base Station climate equipment for the RBS. It has a removable compact flashcard which makes it possible to replace a faulty DXU without the need for loading RBS software from the BSC. The DXU is also provided with four connections for transmission lines. It can handle both 2 Mbit (E1) and 1.5 Mbit (T1) PCM links. The DXU has hardware support for EDGE on 12 TRXs. Number of units: 1 FCU – Fan Control Unit The FCU controls the four fans in the cooling system by regulating fan speed.
Radio Base Station RBS 2206 Number of units: 0 – 1 Bias injector The bias injector is used to provide the ddTMA with DC power, from the TMA-CM, over the RX/TX feeder cables. Six bias injectors can be connected to one TMA-CM. The BIAS-IC is mounted outside the cabinet, as close to the RF output as possible. Number of units: 0 – 6 BBS The RBS 2206 can be provided with battery back-up from an external cabinet, either a BBS 2000 or a BBS 2202.
RBS 2206 Radio Base Station TMA-CM – Tower Mounted Amplifier - Control Module The Control Module is used to provide up to six ddTMAs with 15 V DC power through the bias injector. It is also used to identify TMA faults and forward this information to the alarm module in the RBS. The TMA-CM is mounted in an OXU position. Number of units per cabinet: 0 – 2 6 Interfaces In this section all external and internal connections are listed, as well as the test interface and the operator interface.

Radio Base Station RBS 2206 External Indicators The RBS 2206 has three indicators on the cabinet door: RBS Fault There is a fault in the RBS. External Battery Mode The RBS is operating on battery power. External Alarm There is at least one external alarm present in the RBS.
RBS 2206 Radio Base Station There are two ways to connect power to the base station. They are: • Single phase line to neutral. • Single phase line to line. Note: Table 9 When single phase line to line is used, each PSU requires two circuit breakers.

It is available in an external cabinet. It is possible to supply external transmission equipment from the battery cabinet.
Radio Base Station RBS 2206 • T1 1.5 Mbit/s, 100 Ω balanced PCM line. • E1 2 Mbit/s, 75 Ω unbalanced (balun used), or 120 Ω balanced line. PCM Overvoltage Module This module contains overvoltage protection for the PCM lines. If the PCM lines are terminated in equipment outside the RBS equipment room, these lines must be protected by overvoltage protectors (OVP) in the DF. Failure to do so might damage the DXU-21, if a voltage transient is transported along the cable.
RBS 2206 Radio Base Station DC. The external alarms are defined during installation using the Operation and Maintenance Terminal (OMT) or from the BSC. 10 Standards, Regulations and Dependability In this section a brief overview of standards, type approval, and electromagnetic compatibility are stated. 10.1 Safety Standards In accordance with the market requirements, the RBS 2206 complies with the following product safety standards: 10.
Radio Base Station RBS 2206 Dependability The RBS 2206 is designed for a technical lifetime of 25 years (24-hour operation). The following preventive maintenance conditions must be fulfilled to guarantee the availability of the RBS: Fans The fans must be inspected (cleaned if necessary) every year. The lifetime is estimated to at least 5 years. Air filters The air filters must be regularly inspected and cleaned (interval depends on the environmental conditions at the site).

RBS 2106 and RBS 2206 3 Radio Configurations Definitions 7RZHU 0RXQWHG $PSOLILHU 70$ The TMA compensates for signal loss in the receiver antenna cables, reduces system noise and improves uplink sensitivity. The TMA can consist of a duplex filter. Duplex is the function that allows communication in two directions (sending and receiving) on one channel. The TMA used for 12 TRX products is Dual Duplex TMA (ddTMA). Some configurations can use a TMA designed for reception only (rTMA).

One possible application using SPB together with hybrid combiner is creating overlaid and underlaid cells during cell planning, as described below: 1 One underlaid cell consists of the second TRX in the first dTRU and the first TRX in the second dTRU. SPB is used in this cell. 2 One overlaid cell consists of the two other TRXs. SPB is not used in this cell.

RBS 2106 and RBS 2206 8 Radio Configurations Co-Siting with TDMA RBS Using an ASU The ASU is used for co-siting with a TDMA RBS, more specifically RBS 884 for 800 MHz and 1900 MHz, and RBS 882 for 800 MHz only. The unit allows a TDMA cabinet to share receiver antennas with a GSM cabinet. The ASU is installed in a dTRU based GSM cabinet. The implementation is for 800 and 1900 MHz. The end configuration differs for different site configurations of the TDMA RBS.
