Ericsson shall have no liability for any error or damage of any kind resulting from the use of this document. The RBS 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 or with their backs against a wall.
For dimensions, see Figure 1 on page 5. A shorter distance may restrict the airflow. A space of mm is recommended above the cable ladder to make cable installation work easier. The cabinet cover protrudes 77 mm in front of the cabinet. Expansion cabinets and racks can be positioned to the left or to the right of the master cabinet. However, expansion to the right is recommended in order to follow the same standard globally. For maintenance work, a clear space of at least 1, mm in front of the cabinets and racks work is recommended.
Note: Space for future expansion must be considered, as indicated by the dotted lines in the figure above.
Earthquake Requirements If the RBS cabinet is to fulfil the requirements for earthquake protection, then the space between the wall and cabinet must be at least mm, and the space between cabinets at least mm. The base frame is used as a template to mark new holes. Functions automatically return to specified levels as soon as the environmental conditions return to within normal operating limits.
Refers to a period of no more than 72 consecutive hours and a maximum of 15 days in a year. Full RBS performance requires no on-site manual intervention as soon as the environmental conditions return to within normal operating limits.
Refers to a period of no more than 96 consecutive hours and a maximum of 5. The figures show test points and the tables show the noise dispersion generated by a free-standing RBS with three fans and by an RBS mounted against a wall.
Note: The acoustic noise dispersion values for a free-standing cabinet and a cabinet installed against a wall were tested according to the ISO standard. Deviations from these values can be experienced due to the nature of materials in the environment where the cabinet is installed. Objects near the cabinet can reflect or absorb sound and thus affect acoustic dispersion.
The acoustic noise dispersion values were tested by measuring the sound intensity by scanning at 0. The cabinet is tested for seismic exposure with a test frequency of 1—35 Hz. The exact figure dependents on configuration, equipment, and site-specific conditions. Ericsson has performed a free-space near-field RF exposure assessment of typical configurations of the RBS with a recommended antenna.
The resulting dimensions, in metres, for a compliance boundary for both public and occupational exposure are shown in Table 8 on page The compliance boundary is defined as a cylinder around the antenna. See figure below. The antenna is not located at the centre of the cylinder. Instead it is located almost at the edge, facing towards the centre of the cylinder.
The distance between the rear of the antenna and the edge of the cylinder is the Distance behind antenna. The height of the cylinder is the antenna height plus equal distances above and below the antenna. The cylinder shape overestimates the compliance distances right beside the antenna.
As the antenna field distributions will differ, complete calculations or measurements may be necessary to establish the compliance boundary for other configurations chosen by the customer. For further information on calculation methods, see Radio Frequency Electromagnetic Fields.
In reality the occupational compliance distance by the side, in line with the front of the antenna, is less than 0. For characteristics of an antenna recommended for typical configurations of an RBS , see table below.
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. Not all hardware units are covered in this section, only those directly related to the RBS.
It is the interface between the transceivers and the antenna system. The DRU can be configured as either combined mode or uncombined mode. Number of units per cabinet: 1—6. Number of units per cabinet: 0—1. The DXU is also provided with four ports for transmission interfaces. It can handle both kbps E1 and kbps T1 transmission interfaces. Each distribution circuit in the cabinet is connected to a IDM circuit breaker. It improves the receiver sensitivity. Overvoltage protection for external alarm cables.
Number of units per cabinet: 0—2 7 Interfaces This section describes all external and the operator interfaces. The earth grounding screws are located on the top and bottom of the cabinet on the left-hand side.
External connectors and operator interfaces are located on the corresponding hardware units. For more information about the operator interface, see Optical Indicators and Switches.
It is available in an external cabinet. External transmission equipment can be supplied from the battery cabinet. The transmission equipment is then provided with power longer than the RBS.
In the event of AC power failure, the batteries deliver the necessary power to the radio cabinet as well as to the transmission equipment, if used. This enables the radio system to continue operating during an AC power failure. The figures in the table have been rounded up or down to the nearest 0. Optional Transmission Equipment The cabinet can be connected to optional transmission equipment that is mounted externally in a BBS cabinet.
The external alarm device can set the alarm using either an open or a closed condition. The alarm device connected to the screw terminals should be isolated relay contacts. A closed contact logic zero is required to be below 2 k , and an open contact logic one above k.
The current through a closed 0 W contact is 1. The voltage between terminals with an open contact is 24 V DC. The external alarms are defined at the installation. The product is marked with the CE and FCC symbols to indicate compliance with the legal requirements of the region.
Dependability The RBS is designed for a technical lifetime of 24 years hour operation. The following preventive maintenance conditions must be fulfilled to guarantee the availability of the RBS: Fans The fans must be inspected and cleaned if necessary every year.
Their estimated lifetime is at least 10 years. Vandal Resistance If cover is used, unauthorized access is not possible without damaging the unit.

I will go through the different ericsson starting with the battery fuse unit, then the CPU, then the power supply and at last, which also have a long teardown video, the power amplifier.
