User’s manual for Repeater MRx01B Power
1 Introduction
1.1 Intended purpose
Cellular telephone systems transmit signals in two directions between base stations and
mobile telephones within the signal coverage area.
If weak signal transmissions occur within the coverage area because of indoor applications,
topological conditions or distance from the transmitter, a Repeater is used to extend
transmission range. In the downlink path the Repeater picks up the signal from a donor
antenna of an existing cell, amplifies and re-transmits it into the desired dark spot. In the
uplink direction the Repeater receives signals from mobile stations present in its coverage
area and re-transmits them to the corresponding base station.
1.2 About the MRx01B Power
This repeater bi-directionally amplifies signals between multiple mobiles and a single base
station in the frequency band. It is employed where poor topological conditions cause weak
field strengths. It can provide highly selective amplification of band segments or channels in
the frequency band.
MRx01B Power modules can be combined with other repeater modules in order to create a
multi-band repeater system. Modules operating in PCS1900, GSM1800, GSM900, or
AMPS800 bands are available. When different modules are combined a common antenna and
control interface are available.
The MRx01B Power can be set-up locally or remotely. A PCMCIA slot for modem operation
is an available option. The repeater has a large number of functions that can be monitored and
changed by the operators via a terminal emulation program or the MIKOM OMC software
platform. An easy to understand and simple to learn communication language is available to
help the operator query status reports from the repeater or to change settings.
1.3 Modular design
The MRx01B repeater’s modular design provides the flexibility in addressing present and
future system needs. Each repeater is custom configured. The main unit includes equipment
common to all systems ( cabinet, control module, power supply, mother board ). To this main
unit hardware modules are added as needed. In addition to different duplexers, a wide range
of conversion modules can be selected depending on the used network system.

User’s manual for Repeater MRx01B Power
1.4 Applications
The ability to customise the equipment in this way makes it possible to target the MRx01B to
specific needs. For example, the following are some of the application options available with
the MRx01B.
• Channel selective or band selective
• CDMA or TDMA
• iDEN and analog networks
• GSM900 or GSM1800
• PCS1900

2 Functional description
The Repeater MRx01B Power can be equipped from one to four bands or channels depending
on the used technology.
The following block diagram shall illustrate the configuration of the system.
*: one physical module contains UL and DL
**: with more than two modules, the amplifiers are included; both are in one housing
figure 2-1 Block diagram of MRx01B Power
2.1 General
The Repeater consists of two amplifier chains, which are connected antiparallel. The
receive path of one direction is connected to the transmit path of the other direction by a
frequency separation unit, in the following denominated as a duplexer, which combines
both signals to an antenna (see chapter 2.5).
After the duplexer the signals get to a pre-amplifier and afterwards to a conversion
module (see chapter 2.2). Then the signals are combined by the active combiner (see
chapter 2.6) and afterwards amplified by the feedforward amplifier (see chapter 2.8),
which provides the required output power.
M0079A1A.doc Id.-No. 151775 Page 13 10-March-00
User’s manual for Repeater MRx01B Power
In the feedforward amplifier a power detection measures the output power and controls
the gain. This is called Automatic Level Control (ALC) and keeps intermodulations
below an adjustable value. Finally, the signals are fed to the antenna.
2.2 Conversion modules
The task of the conversion modules is to amplify the
receive signals and to convert them into an intermediate
frequency. The signals, then, proceed a filter stage
comprising of highly selective filters, and run through a
digital controllable attenuator. The attenuation can be
set in steps of 2 dB, locally or remotely. By using the
same synthesizer frequency, that was used to convert the
signals down to intermediate frequency, the
intermediate frequency is mixed up to the original
frequency.
The synthesizer is controlled via an I²C-Bus. In case of a
breakdown in mains, gain or frequency data are nonvolatile stored in an EEPROM on board.
The yellow label on the top shows the current ALC and
CFO values related to the module.
See figure 2-2 Top view of a conversion module for an
exemplary channel or band module.
figure 2-2 Top view of a conversion module
2.3 Mother board
The function of the mother board is the communication between the conversion modules and
the control module via the I²C-Bus.
In the three and four channel configuration there is a mother board implemented on the lefthand side and on the right-hand side of the Repeater.
In the one and two channel configuration of the Repeater there is only one mother board
mounted on the right-hand side (see figure 9-2 and figure 9-3).
Mother boards are located underneath the conversion modules.

User’s manual for Repeater MRx01B Power
2.4 Control module SM 2009 ( Rev. 07 and higher )
The control module SM 2009 is a DOS compatible micro computer. The whole
communication between the operator and the Repeater can be done via the control module. By
using either the RS232 interface in connection with a modem card and a mobile the Repeater
can be controlled remotely or locally by using a VT100 terminal, i.e. a PC emulating the
VT100 terminal.
Frequency and gain, power down of RF stages and ALC can be controlled and status
messages can be received remotely. In case a modem or a mobile is connected, automatic
alarm messages can be received by the operator.
The data transfer between the control module SM 2009 and the mother board is realized by
the I²C-Bus system.
The I²C-Bus concept was developed by Philips for the serial connection of integrated circuits
within one device. Two wires, SDA - serial data and SCL - serial clock, carry information
between the devices connected to the bus. Each device is recognized by a unique address and
can operate either as transmitter or receiver. The MRx01B Power I²C-Bus concept is working
with a bit rate of 1.5 kbit/s.
All MRx01B Power configuration parameters are stored in an EEPROM on the control
module if a power supply failure occurs.

feedforward amplifier.
figure 2-7 Top view of the active combiner module
2.7 Measuring aids
With built-in RF probes test signals can be applied or detected. The probes provide a coupling
factor of 30 dB respectivly 20 dB. Each duplexer (uplink and downlink) is equipped with one
30 dB coupler, the UL Input duplexer additionally with a 20 dB coupler for a modem or
mobile (see chapter 4 Optional equipment). This facilitates measurements under all
operational conditions, while an antenna or a dummy load may be connected.
The position of the couplers on the duplexers is shown in figure 2-6 Top view of the
duplexers.

STYLEREFSEQARABICFunctions and features
3.1 Band and channel selectivity
The selectivity is achieved by highly selective filters in the IF part of the band / channel
modules.
3.2 Gain setting
The gain can be changed by introducing attenuation into the amplifier chain. By using a rotary
switch the attenuation can be adjusted locally in the range from 0 dB to 30 dB maximum in
steps of 2 dB. The attenuation can be set for the UL and DL path separately.
The rotary switches are mounted on the mother board. These switches are accessible through
the long hole between the two conversion modules (see figure 3-1 Position of rotary

3.3 ALC
In order to protect the amplifiers from overload and to prevent the system to generate spurious
emission, the amplifiers have an Automatic Level Control, designed to limit the output power
to a defined level. A part of the output power is rectified, amplified and used to control an
attenuator network.
FNote: The ALC protects the feedforward amplifier. To keep spurious emissions
below certain limits, the input power into the Repeater and the attenuation
settings of the repeater have to be considered properly.
3.4 CFO
Each conversion module has got a different offset of the set center frequency. This offset is
compensated by software settings (see software manuals).These settings are already factory
set and should only be changed when neccessary. The CFO (center frequency offset) is noted
on the label on top of the conversion module.
3.5 BITE and alarms
The Built-In TEst concept comprises the monitoring of the power supplies, the operational
currents in the conversion modules, the mother board and the remote control interface.
Furthermore, the synthesizer lock and the temperature of the Repeater are monitored.
There are three multicoloured LEDs mounted on the control module. The LED L3 indicates
the presence of electrical power of +12VDC in the Repeater. Every alarm is indicated by the
failure LEDs, L1 and L2.
For the position of the LEDs on the control module see figure 2-4 Configuration of the control
module ( Rev.07 and higher ).
All alarms can be checked by typing the ‘STATUS HIST’ command. Minor alarms with no
influence on the system can be cancelled by typing the ‘ALARMACKN’ command, e.g. ALC
active, VSWR or door open. The following print screen illustrates a possible ‘STATUS
HIST’ report
In case a hardware failure is detected the concerning hardware module has to be replaced. An
alarm can be acknowledged manually by software command. If all alarms have been
acknowledged the summary error LEDs are set back to green indication.
In case of mains power failure all data of the STATUS HIST list are lost.
The alarm can also be sent to the OMC.

3.5.1 Handling of alarms
As soon as the software recognises a valid alarm, a message is transmitted to the OMC.
If the repeater is operating in modem mode the alarm message ‘MIKOM> REPEATER
REQUIRES OPERATOR ATTENTION’ will be sent via modem to the terminal or the OMC.
The first of two stored telephone numbers will be dialled. In case a connection cannot be
established the second telephone number will be dialled. If this should be unsuccessful as
well, the call will be repeated after a pre-set delay. Default setting is 10 minutes. The
repetition cycle can be set by software.
The alarm check routine is searching every 10 seconds for alarms ( polling principal ). To
decide whether an alarm is a valid alarm it must remain for 5 polling cycles, only then it will
be recognized and entered in the alarm history. As soon as the alarm is valid the contacts of
the alarm relay at the mother board are set. Additionally two summary error LEDs are set to
red light to indicate an alarm. These LEDs are mounted on the control module (see figure2-4).
The entry in the alarm history describes the alarm type, the time and the date when it
occurred. It is not possible to locate the defect module, only the reason.
Entered alarms in the alarm list can be acknowledged by simply ringing back and typing a
software command. It is also possible to acknowledge alarms in local mode. Acknowledged
alarms will be indicated with ‘-ACK’. As soon as the alarms have been acknowledged the
alarm relay will be reset and the summary LEDs switch back to green light again. To switch
off external alarm indication devices can only be done by acknowledging the alarms.
If the same alarm cause occurs again, it will be entered in the alarm list ( not acknowledged )
after 5 polling cycles. An already acknowledged alarm must have an interruption of at least 5
polling cycles to be detected by the software as a new alarm. Only then the alarm will be
entered again in the alarm history ( not acknowledged ).
All data of the alarm history are lost, if the repeater will be booted by software or if the
repeater was disconnected from mains. There exists no command to delete the alarm history,
to boot the repeater is the only way to clear the alarm history.
The alarm list has a capacity of about 50 alarm entries. If more alarms occur the oldest
message will be deleted first ( FIFO principal ).
In the software exists no alarm clear message, i.e., the repeater sends no message to the
terminal or the OMC if an alarm has disappeared by itself.

User’s manual for Repeater MRx01B Power
3.5.2 Status report
Two instructions enable the operator to gain knowledge of the system status. Typing the GET
command will be responded by a listing of all settings of the Repeater. STATUS will be
responded by a listing of all individual status information.
The complete listing of the dialogue language with the processor of the control module
including the instructions to and the messages from the system is available as a separate
manual.
3.5.3 Severity levels
This parameter defines five severity levels for an alarm and can be set in the alarm mask
(detailed description in the software manual). The severity levels indicate how the capability
of the managed object has been affected.
The levels are described below and are ordered from most severe to least severe:
- Critical: The critical severity level indicates that a service affecting condition has
occurred and an immediate corrective action is required to restore the
capability of the managed object.
- Major: The major severity level indicates that a service affecting condition has
developed and an urgent corrective action is required. Such a severity can be
reported, for example, when there is a severe degradation in the capability of
the managed object and its full capability must be restored.
- Minor: The minor severity level indicates the existence of a non-service affecting fault
condition and that corrective actions should be taken in order to prevent a more
serious failure. Such a severity can be reported, for example, when the detected
alarm condition is not currently degrading the capability of the managed object.
- Warning: The warning severity level indicates the detection of a potential or impending
service affecting failure before any significant effect has been caused. Action
should be taken to further diagnose and correction of the problem shall prevent
a more serious service affecting failure.
- Disable: The disable severity level indicates that the detected failure has no influence on
the system and shall not be sent to the terminal.

4 Optional equipment
The following modules can be integrated as an option.
4.1 VSWR module
VSWR signal is continually measured by a special VSWR module. An alarm can be given for
VSWR < 10 dB.
4.2 External alarms
With the following option it is possible to monitor 4 external alarms via the Repeater
software. Hence the status of the connected device, e.g. UPS, can be monitored.
The contacts of the alarms can be accessed at clamps on the main board (right-hand side of
the Repeater).
The electrical connection has to be
as follows:
External alarm 4 (high active)
External alarm 3 (high active)
External alarm 2 (low acitve)
External alarm 1 (low acitve)
Ground
figure 4-1 Clamps for external alarms
Configuration: 5 V / 0.5 mA max. for open collector applications.
All external alarms are normally high without connection. Due to the fact that the external
alarms 3 and 4 are high active, they have to be connected to ground to prevent an alarm
message.
M0079A1A.doc Id.-No. 151775 Page 29 10-March-00
User’s manual for Repeater MRx01B Power
The factory-set response after typing the software command STATUS EXTALARM is for
instance „EXT. ALARM 1 OK“, if the alarm is not active and „EXT. ALARM 1 FAILURE“,
if the alarm is active.
The name for each external alarm and the name for the alarm message can be defined by the
customer with the corresponding software command.
The following example describes the response for the external alarms to control an UPS.
Example: External alarms if the UPS is active
EXTERNAL ALARM STATUS

4.5 Battery backup module
If backup is required only for the control module and the modem, low capacity batteries are
available to operate controller and modem for at least ten minutes under normal
environmental conditions.
Battery backup is provided for the control module to transmit alarm information in case of
power failure. The battery type is a NiCd 8.4V/300 mAh. The battery backup is sufficient
enough to support multiple dial out attempts via modem in case of ‘system engaged’ or other
communication problems for at least ten minutes under normal environmental conditions.
F Note: This battery backup module is provided for the control module only.
The batteries are protected from deep discharge by use of a low voltage disconnect circuit. A
local switch is provided to disconnect the battery backup system during maintenance to ensure
that all circuits are voltage-free.
The switch is located on the battery backup module.
Switch ON (default) OFF
Battery backup active Battery backup not active
The module is directly plugged into the control module. During the charging process a green
LED V7 on the module indicates, that the battery is charged at the moment. After finishing
the process the LED V7 will be switched off.
The batteries are mounted underneath the modem mounting plate (see following figure).

5.1 Mechanical installation
F Note: Due to power dissipation the Repeater may heat up the air volume inside
the cabinet and reach a very high temperature. Therefore it is necessary to mount the
Repeater in the vertical plane to a wall or a mast without additional enclosure to provide
sufficient ventilation. Between the housing and the wall a minimum distance must be
kept in order to provide air circulation.
The Repeater must be mounted in the
vertical plane to a wall or a mast, which
means the connectors have to be located at
the bottom.
Use the mounting brackets, which are part
of the delivery. This will guarantee a
minimum distance between the wall and the
Repeater housing. The cabinet must be
fixed to the wall (brackets) with four
screws.
Check the correspondence of the wall
mounting kit and the wall.

figure 5-3 Wall mounting brackets
Use the wall mounting sheet to mark the position of the drilling holes. Drill 4 holes and screw
the mounting brackets to the wall. Attach the upper two socket head cap screws M8.0x16 to
the Repeater housing. Now it is possible to hang the Repeater into the mounting brackets. Fix
then the lower two socket head cap screws M8.0x16 and the 2 tire bolts.
F Note: The unit is heavy-weight. Make sure that a suitable mounting surface is
used. Only adequate manpower is allowed to handle the system.
The installation position of the Repeater follows from the installation drawing (see figure 9-1
Installation drawing of the Repeater). Make sure that there is free access to the electrical
connections. The allowed bending radius of the connected cables must not be exceeded.
Furthermore the Repeater shall be mounted in a way that there is free access to the individual
units inside the cabinet, while the door of the Repeater is open.
Therefore keep a clearance distance of 1 m on each side, on top and below the unit.
See figure 5-2 Top view and clearance distance.

5.2 Electrical installation
FNote:
5.2.1 Grounding
Grounding has to be performed by all means. Therefore a grounding bolt is provided at the
cabinet. An earth bonding cable will be mounted in the factory and will be delivered with the
unit. Don’t use the grounding screw for connecting external devices.
The complete grounding kit is part of the delivery schedule, see figure 5-4 Grounding kit.
ESD precautions have to be observed! Before working inside the cabinet
use the available grounding system to connect ESD protection measures.
The electrical installation has to be performed in accordance with the
safety regulations of the local authorities. Due to safety reasons the
electrical installation must be performed by qualified personnel. The
cover of this unit should not be opened while power is applied.
Subsequent installation, commissioning and maintenance activities that
require the unit to be powered with the cover open shall only be carried
out by suitably qualified personnel

5.2.2 Power connection
A firmly installed mains cable 3 x 1.5 mm² is used, which is fed into the housing through a
watertight cable gland. Due to safety reasons the power supply lead has to be protected by two
8 A fuses. Inside the Repeater, mains are connected to a screw terminal.
See figure 5-5 Screw terminal for the position of the two 8 A fuses.
Before connecting electrical power to the Repeater grounding has to be performed. The
Repeater is equipped with a firmly connected power cord 3 x 1.5 mm². Due to safety reasons
the power supply lead of the Repeater has to be protected with two 8 A fuses, type MT. In the
event the length of the power cord should not be sufficient it can be replaced by a longer
cable.
Fuses F1 and F2
figure 5-5 Screw terminal
F Note: If the power supply lead has to be replaced use a cable of the same quality.
5.2.3 Connection of the antenna cables
The Repeater has two female antenna connectors 7/16 (optionally N). For mounting the
corresponding cable connectors we recommend to refer to the applicable documentation of
the respective connector manufacturer. The bending radius of the antenna cables must remain
within its specification. This will warrant proper operation of the system; otherwise changes
in the electrical behaviour of the cable might occur which could cause malfunction of the
Repeater system.

6 Setting to work
6.1 Preparation
F Note: It is not allowed to operate the Repeater without termination of the
antenna connections! The termination can be performed by the antenna
connection as well as a dummy load or the 50-Ohm-terminated connection
of a measuring instrument.
Before bringing the Repeater system into service it is necessary to measure the antenna
isolation. The Repeater system has its maximum available gain when the attenuation is set to
zero. On site the maximum allowed gain is 15 dB less than the value of the antenna isolation.
In order to check the function of the Repeater system on site it is advisable to operate the
Repeater system with 50 Ohm termination. This makes it possible to set the necessary gain
and to test the set value without the necessity of transmitting on air.
In order to perform settings the Repeater has to be opened. Please, ensure not to damage the
seals, which are on the modules situated on the conversion modules inside of the Repeater,
because this would lead to risk the success of warranty claims.

8 Maintenance
8.1 General
F Note: The Repeater does not require preventative maintenance measures.
It is only recommended to replace the RAM/RTC battery after three years usage as a
prophylactic measure. The nominal lifetime of these batteries is five years under normal
environmental conditions.
In the event of a malfunction it is advantageous to check the status of the antenna systems as
well as the continuity of the entire cabling including connectors, before replacing the
modules.
Maintenance on the Repeater shall be performed only by replacing modules. Soldering on
printed circuit boards shall be avoided. In order to sustain warranty take care not to damage
unintentionally the seals on the modules.
The spare part list, consequently, contains only units, which can be replaced without tuning or
complex soldering work.
F Note: Defect parts should be replaced by original parts from MIKOM only.
All interventions inside the housing are at one’s own risk.
During maintenance ensure that the Repeater has been disconnected from
mains.
Open the lock at the connector panel and remove the cover plate. To open the housing use a
Torx key and unscrew the four Torx screws.
8.2 Replacement of the fuses (mains)
The mains cable is protected with two fuses F1 and F2 8A type MT. They are accessible
inside of the Repeater at the fuse terminal on the right side. Open the screw plug for the fuse
and take out the fuse.
F Note: Use only fuses of the same type and the same rating when replacing!
See figure 5-5 Screw terminal for position of the 8A fuses.
