2. FUNCTIONAL DESCRIPTION
2.1.
GENERAL
Cellular telephone systems transmit signals in two directions between base
transceiver station (BTS) and mobile stations (MS) 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 (DL) path, the repeater picks up
the signal from a donor antenna of an existing cell, processes and retransmits it into
the desired dark spot. In the uplink (UL) direction, the repeater receives a signal from
mobile stations present in its coverage area and forwards them to the corresponding
BTS.
2.2.
REPEATER DESIGN
The repeater MRx03P is a band selective amplifier which bi-directionally amplifies
signals between a base transceiver station and mobile stations in the corresponding
network. It can provide highly selective amplification, thus enabling radio coverage in
regions where satisfactory quality of communication is disabled. The following figure
shows the configuration of a MIKOM repeater MRx03P.
figure 2-1 Configuration of a MRx03P
The MRx03P can also be combined with other repeater systems to create a
combined repeater system. When different modules are combined, a common
antenna terminal and a common control interface is available.

COMPONENTS OF THE MRX03P
The actual repeater configuration can be seen at the configuration list which is part of
the delivery.
2.3.1. Duplexer
The task of the duplexer is to isolate uplink from downlink, i.e. to separate the
transmitting path from the receiving path. The pass bandwidth of the duplexer is the
entire width of the UL- and DL band of the corresponding network.

figure 2-2 Duplexer
2.3.2. Measuring Aids
With built-in RF probes at the duplexers, test signals can be applied or detected
(see figure 2-2). The probes are provided with different coupling factors, 30 dB for
measurements and 20 dB for the optional modem. Each antenna port is equipped
with one coupler. This facilitates measurements under all operational conditions while
an antenna or a dummy load may be connected.

USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P
2.3.3. Conversion Module
The task of the conversion module is to amplify the received signals and to convert
them into an intermediate frequency. Then, the signals proceed a filter stage
comprising of highly selective filters and run through a digital controllable attenuator.
figure 2-3 Conversion module
Each link of a conversion module is provided with filters which guarantee the high
selectivity. There the desired bandwidth and the desired centre frequency can be set.
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.

USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P
2.3.5. Control Module
The control module is a DOS compatible micro computer. The whole communication
between the provider and the repeater can be done via the control module.
The repeater can be controlled remotely or locally via a VT100 terminal or a PC
emulating the VT100 terminal.
To control the repeater remotely, use either the RS232 interface in connection with a
wireless modem or the PCMCIA interface in connection with a modem card and a
mobile or PSTN network adapter. The RS232 interface and the PCMCIA interface
are located on the control module.
Frequency, gain, power down of RF stages and ALC can be controlled and status
messages can be received remotely. In case a PSTN modem or a mobile is
connected, automatic alarm messages can be received.
The data transfer between the control module 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, serial data (SDA) and serial clock (SCL), 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.
All MRx03P configuration parameters are non-volatile stored in an EEPROM on the
control module if power supply failure occurs.

3. OPTIONAL EQUIPMENT
The actual repeater configuration can be seen at the configuration list which is part of
the delivery.
3.1.
MODEM
The modem option enables the provider to set parameters and to query the status of
each repeater remotely. Furthermore, the modem can be set to send all occurred
alarms of the repeater directly to a provider’s terminal, e.g. to the OMC. This can be
done either via a wireless modem or a PSTN modem (Public Switched Telephone
Network). Thus, the alarms can be evaluated and eliminated promptly. It is possible
to install the wireless modem or the PSTN modem on site!
∫
Check the communication mode between the modem and the terminal. If
necessary, set the following parameters:
Bit rate / bit per second:
9600 baud
Number of data bit:
8 bit
Parity bit:
No parity
Stopbit:
1 stopbit
These settings can only be changed after connection to the terminal. If a different
modem is required or if the quality of the line does not allow to use the set
parameters, the settings have to be changed in PC mode. The same applies for all
other parameters which can be set previously for modem mode by software.
3.1.1. Initstrings
Depending on the provider’s network and the used modem type, it is necessary to
adjust the initstring. The following initstrings are factory set:

3.1.2. PSTN Modem
A Hayes compatible PSTN modem can be connected to the control module SM2009.
The telephone cable has to be fed through a labeled grommet of the connector panel
and must be connected to the designated clamps.
For the standard modem type DigiTel 56Euro, use clamps 2 and 3 to connect the
telephone lines a and b. Previous standard modems type DigiTel 34P use clamps 1
and 4. In case of failure try both possibilities to check the functionality of the modem
connection.

EXTERNAL ALARMS
With the external alarms option, it is possible to monitor the status of connected
devices via the repeater software, e.g. a UPS. The DIP-switches of the Ext.-Alarms
switch on the control module have to be set to position ON “Ext. Alarm 1-4”.
∗ Note:
If a PSTN modem is required, only two external alarms are
available because the PSTN modem reserves two lines!
The connecting clamps are located on the connecting board mounted on the
duplexer (BTS side).
figure 3-3 Location of external alarm clamps
All external alarms are normally high (5V) without connection. Via the software
command SET LOGIC, the external alarms can be set to high active (H) or low active
(L). Depending on the settings, the external alarms show the status “failure” or “OK”
on the display. The configuration for open collector applications is 5V / 0.5 mA.
When only 2 external alarms are required, ensure that the other 2 external alarms are
set to low active, otherwise the status will always show an alarm.
∗ Note:
The name for each external alarm and the name for the alarm
message can be defined by the customer with the corresponding
software command (see software manual)!
∗ Note:
A special software blocking must be removed to use the external
alarm option. This can only be carried out by authorized persons
from MIKOM.

BATTERY BACKUP
The repeater can be provided with the battery backup option to enable alarm calls in
case of power failure. The battery backup module supports multiple dial out attempts
via modem in case of “System engaged” or other communication problems for about
ten minutes under normal environmental conditions.
The batteries are protected from deep discharge by use of a low voltage disconnect
unit. A local switch is provided to disconnect the battery backup option during
maintenance to ensure that all circuits are voltage-free. The switch is located on the
battery backup module.
The module is directly plugged onto the control module and can be installed on site.
During the charging process, a green LED on the module indicates that the battery is
charged at the moment. After finishing the process, the LED will be switched off.

4.1.
MECHANICAL INSTALLATION
4.1.1. General
Note:
Due to power dissipation the repeater may reach a very high
temperature. Therefore, it is necessary to mount the repeater
vertically to a wall or a mast without additional enclosure. A
clearance distance of one metre above and below the unit should be
kept to provide sufficient ventilation. Between the housing and the
wall, a minimum distance of 20 mm must be ensured.
Note:
The weight of the repeater is
approximately 14 kg in standard
configuration. Only adequate
manpower is allowed to handle
the weight of the system.
Note:
If it is impossible to mount the
repeater with the mounting
brackets due to an uneven
surface (e.g. a bulged wall in a
tunnel), alternative fastening
devices may be used. These
fastening devices must fulfil the
following requirements:
Note:
The external strain must not be
increased by the alternative fastening
devices. Holding devices, which expose
the repeater to enhanced vibration or shock
due to a greater distance from the wall (leverage)
or due to a lower rigidness or stability
(vibration), must not be used.
Note:
The repeater’s external strain specifications must not be exceeded,
particularly the exposure to vibration and shock (please refer to the
MIKOM “Environmental and Safety Leaflet” for further detailed
information).
Note:
Exceeding the specified load limits may cause the loss of warranty!

ELECTRICAL INSTALLATION
4.3.1. Grounding
Grounding must be carried out under all circumstances. An earth bonding cable must
be connected to the grounding bolt provided at the outside of the cabinet on the lefthand side. Do not use the grounding screw for connecting external devices. The
complete grounding kit is part of the delivery schedule.
The complete grounding kit is part of the delivery schedule.
figure 4-3 Grounding bolt
4.3.2. Mains Power Supply
Before connecting electrical power to the repeater, it must be grounded. The repeater
is equipped with a firmly connected mains cable which is fed into the housing through
a watertight cable gland. Due to safety reasons, the power supply lead must be
protected by fuses. Inside the repeater, the mains cable is connected to a screw
terminal on the connecting board. In case the length of the power cable should not be
sufficient, it can be replaced by a longer cable.

5. COMMISSIONING
5.1.
PREPARATION
5.1.1. General
Please read the description carefully to avoid mistakes and proceed step by step as
described. The repeater must not be operated with open antenna ports. This means
that each antenna port has to be terminated with either a 50Ω resistor, a dummy load
or a connected antenna. The repeater could be damaged when operated without any
50Ω terminations.
When opening the repeater, do not damage the seals on the devices inside the
repeater. Warranty void if the seals are broken!
5.1.2. BCCH-Channel
Apart from the antenna isolation measurement described in chapter 5.1.3, it is also
necessary to measure the BCCH level (BCCH=Broadcast Control Channel). The
resulting max. allowed repeater gain of the antenna isolation must be compared with
the resulting max. allowed repeater gain of the measured BCCH channel. The lower
gain has to be set for the repeater.
The following example clarifies how to set the correct gain:
Antenna isolation:
Antenna isolation:
100 dB
Safety Gain Margin (SGM)*: 15 dB
------------Allowed max. gain:
85 dB
BCCH channel:
Power out**:
Received level of BCCH:
Allowed max. gain:
+30 dBm
-(-40) dBm
---------------70 dB
* Refer to chapter 5.1.3 Antenna Isolation for further information about SGM.
** Max. Pout required by customer, but not higher than the rated Pout per channel stated for this
repeater at the required number of channels.
In this case, 70 dB gain has to be set for the repeater.
∗ Note:
If a higher gain is set, the ALC will be active! This might affect the
quality of the signal!

USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P
5.1.3. Antenna Isolation
Before setting the parameters of the repeater, ensure that the antenna isolation is
measured and optimized. The Safety-Gain-Margin (SGM) between the antenna
isolation and the maximum gain of the repeater is specified to +15 dB for all RFrepeaters, i.e. the gain has to be -15 dB less than the isolation value of the antennas.
For better antenna isolation, ICE (Interference Cancellation Equipment) has been
developed for channel selective repeaters in the GSM900/1800 networks as well as
for PCS1900. ICE is specified for a SGM of –5 dB. Following example will show the
significant difference of a repeater with ICE-option compared to a repeater without
ICE-option.
Assumed case of a poor antenna isolation:
• Repeater without ICE
Antenna isolation:
SGM:
Allowed max. gain:
80 dB
- 15 dB
------------65 dB
In this case, the antenna isolation should be improved. The operator has to enlarge
the distance between both antennas or has to shield each antenna from the other.
Sometimes, it is difficult to enlarge the distance or to shield the antenna to reach the
necessary value.
The next example clarifies how to solve the antenna isolation problem with an ICErepeater. The SGM between the antenna isolation and the maximum gain is specified
to -5 dB, i.e. the gain can be +5 dB more than the isolation value of the antennas.
Assumed case of the same poor antenna isolation as in the previous example:
• Repeater with ICE-option
Antenna isolation:
SGM with ICE-option:
Allowed max. gain:
80 dB
+5 dB higher
---------------------85 dB
For further details to ICE or antenna isolation, please refer to MIKOM “Application
Note for Antenna Isolation” or “ICE Datasheet”.

6. ALARMS
6.1.
BITE AND ALARMS
The Built-In Test concept comprises the monitoring of the power supplies, the
operational currents in the conversion modules, the motherboard and the remote
control interface. Furthermore, the synthesizer lock and the temperature of the
repeater are monitored.
All occurred alarms can be checked via software by typing the “STATUS HIST”
command. The provider is then able to acknowledge the alarm manually by the
software command “ALARMACKN”, e.g. ALC active, RSSI, door open or stabilty
control. If all alarms have been acknowledged, the summary error LEDs are set back
to green indication.
If monitored via a modem, automatic dialling will generate a summary alarm
message. The provider can acknowledge the alarm message and can request a
detailed status report.
6.2.
HANDLING OF ALARMS
As soon as the software recognizes a valid alarm, a message is transmitted to the
operator. In remote mode, the alarm can be acknowledged by simply ringing back
and typing ALARMACKN.
If the reason for the alarm has been cleared or if the alarm should continue, a new
alarm message will not be repeated. If there was an interruption of at least one
second after acknowledgement, a new alarm message will be generated.
6.3.
STATUS REPORT
Two instructions enable the operator to get the information of the system status.
Typing GET, commands will be responded by a listing of all settings of the repeater.
STATUS will be responded by a listing of all individual status information which can
be monitored only, but not influenced by SET commands.
The complete listing of the syntax with the processor of the control module including
the instructions and the messages as well as all available alarms from the system is
obtainable as a separate software manual.

8. MAINTENANCE
8.1.
GENERAL
∗ Note
The repeater does not require preventative maintenance measures.
It is only recommended to replace the RAM/RTC battery and the whole battery
backup module 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 by replacing modules only.
Soldering on printed circuit boards shall be avoided. In order to sustain warranty, take
care not to damage unintentionally the seals on the modules. To open the housing,
the upper screws have to be removed first and than the lower screws (see installation
drawing chapter 7.1). Proceed in reverse order to close the housing.
The spare parts list, consequently, contains only units which can be replaced without
tuning or complex soldering work. Those units are all MIKOM modules as well as
internal and external cables.
∗ Note
Defect parts should only be replaced by original parts from
MIKOM. All interventions inside the housing are at one’s own risk.
∗ Note
During maintenance ensure that the repeater has been
disconnected from mains and the battery backup module has been
switched off.
