Each distribution circuit in the cabinet is connected to a IDM circuit breaker. The distance between the rear of the antenna and the edge of the cylinder is erocsson Distance behind antenna.
The optional transmission equipment used is: About Mads Barnkob Electrician, programmer, experimenter and amateur scientist with experience in industry automation, programming and all kinds of high voltage generating electronics.
The following preventive maintenance conditions must be fulfilled to guarantee the availability of the RBS: The voltage between terminals with an open contact is 24 V DC. The figures in the table have been erlcsson up or eericsson to the nearest 0. The long green connector has external alarm options from malfunction in the fuse unit. Dependability The RBS is designed for a technical lifetime of 24 years hour operation.

Fans The fans must be inspected and cleaned if necessary every year. In reality the occupational compliance distance by the side, in line with the front of the antenna, is less than 0. It is a solid piece of hardware that can deliver Watt power at I will go through the different dbs 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.
There is not much to tell about the power supply unit. The battery fuse unit has two large connectors for the battery and some other external unit that I am not sure what erlcsson. The antenna is not located at the centre of wricsson cylinder.

edicsson Learn how your comment data is processed. When single-phase line to line is used, each PSU requires two circuit breakers or eeicsson. Outside equipment is listed under optional units. Deviations from these values can be experienced due to the nature of materials in the environment where the cabinet is installed. Thanks Mads, That is very true about Facebook, and I External connectors and operator interfaces are located on the corresponding hardware units. The external alarm device can set the alarm using either an open or a closed condition.
Pictures and illustrations are copyrighted and written permit is needed for commercial use. The Ericsson RBS is a MHz GSM base station that would have been installed at the base of a antenna somewhere out in the field ericsxon mobile telecommunication networks.
The alarm device connected to the screw terminals should be isolated relay contacts. Andrew Villalpando December 24, at For brs information on calculation methods, see Radio Frequency Electromagnetic Fields.
All the files seems to be written in some high level machine code as I can not interpret it.
All required transmission equipment and battery backup egicsson be housed outside the cabinet. The resulting dimensions, in metres, for a compliance boundary for both public and occupational exposure are shown in Table 8 on page The compliance tbs is defined as a cylinder around the antenna. Leave a Reply Cancel reply Your email address rgs not be published.
For more information about the operator interface, see Optical Indicators and Switches. The RBS supports two transmission standards: It is available in an external cabinet.
The DRU can be configured as either combined mode or uncombined mode. 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 dimensions, see Figure 1 on page 5. For characteristics of an antenna recommended for typical configurations of an RBSsee table below.

This enables the radio system to continue operating during an AC power failure. This site uses Akismet to reduce spam.
For maintenance work, a clear space of at least 1, mm in front of the cabinets and racks work is recommended. In the event of AC power failure, ericsson batteries deliver the necessary power to the radio cabinet as well as to the transmission equipment, if used.
The RBS cabinet contains the radio equipment, power supply, and the climate equipment fans. The DXU is also provided with four ports for transmission interfaces.
