2. INTRODUCTION

2.1. PURPOSE

Cellular telephone systems transmit signals in two directions between basetransceiver station (BTS) and mobile stations (MS) within the signal coverage area.

If weak signal transmissions occur within the coverage area because of indoorapplications, topological conditions or distance from the transmitter, a repeater isused to extend transmission range. In the downlink (DL) path, the repeater picks upsignals from a donor antenna of an existing cell, processes and retransmits them intothe desired dark spot. In the uplink (UL) direction, the repeater receives signals frommobile stations present in its coverage area and forwards them to the correspondingBTS.

2.2. THE MRX01B(i)

The repeater MRX01B(i) is a band selective repeater which bi-directionally amplifiessignals between mobile stations and a base station in the respective mobiletelephone system. It is employed wherever bad topological conditions cause poorfield strengths. It can provide highly selective amplification of the entire band or bandsegments, thus enabling radio coverage in regions where satisfactory quality ofcommunication is not available.

The repeater can be upgraded to provide up to three conversion modules. However,for more than one module, an extension unit is required.

The repeater can be set locally or remotely. A PCMCIA slot or RS232 interface formodem operation is available. The design of the repeater comprises a large numberof functions, which the operator may monitor via terminal emulation programs or theMikom OMC software platform. An easy-to-understand, and fast-to-learncommunication language supports the operator to query status reports from therepeater, or to change settings.

3. FUNCTIONAL DESCRIPTION

3.1. GENERAL

The following figure shows the configuration of a Mikom repeater MRx01B(i).

E0860B1

figure 3-1 Configuration of a MRx01B(i)

The repeater consists of two amplifier chains, which are connected antiparallel.The receiving path of one direction is connected to the transmitting path of theother direction by a frequency separation unit, in the following denominated asduplexer, which combines both signals to an antenna.

After the duplexer the signals pass through a pre-amplifier and afterwardsthrough a conversion module. The task of the conversion modules is to amplifythe received signals and to convert them into an intermediate frequency. Thesignals, then, proceed a filter stage comprising highly selective filters, and passthrough a digitally controllable attenuator. The attenuation can be set in steps of 2dB, locally or remotely. By using the same synthesizer frequency that was usedto convert the signals down to intermediate frequency, the intermediate frequencyis converted back into the original frequency. Then, the signals are combined bythe active combiner and afterwards amplified by the final amplifier, whichprovides the required output power.

3.3. COMPONENTS OF THE MRX01B(i)

The actual configuration of the repeater can be seen at the configuration list, which ispart of the delivery.

3.3.1. Duplexer

The task of the duplexer is to isolate uplink from downlink, i.e. to separate thetransmitting path from the receiving path. The pass bandwidth of the duplexer is theentire width of the UL and DL band of the corresponding network.

With built-in RF probes at the duplexers, test signals can be applied or detected. Theprobes are provided with different coupling factors, 30 dB for measurements and 20dB for the optional modem. This facilitates measurements under all operationalconditions while an antenna or a dummy load may be connected.

3.3.2. Conversion Module

The task of the conversion module is to amplify the received signals and to convertthem into an intermediate frequency. Then, the signals pass a filter stage comprisinghighly selective filters and after that they go through a digitally controllable attenuator.

Each link of a conversion module is provided with filters where the desired bandwidth(for variable bandwidth modules) or the desired center frequency (for CDMA orTDMA modules) can be set.

figure 3-5 Conversion module

By using the same synthesizer frequency that was used to convert the signals downto the intermediate frequency, the intermediate frequency is converted back into theoriginal frequency. The synthesizer is controlled via an I2C-Bus.

3.3.3. Active Combiner

After passing through the conversion module, the signals will be combined by theactive combiner module in the UL and in the DL path.

The active combiner is provided with a power detection which controls the gain andthe output power. This power detection and power control is called Automatic LevelControl (ALC).


M0079A0D.doc

M0079A0D.doc

3.3.6. Control Module

The control module is a DOS compatible microcomputer. The whole communicationbetween 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 PCemulating the VT100 terminal.

To control the repeater remotely, use either the RS232 interface in connection with awireless modem or the PCMCIA interface in connection with a modem card and amobile or PSTN network adapter. The RS232 interface and the PCMCIA interfaceare located on the control module.

Frequency, gain, power down of RF stages and ALC can be controlled and statusmessages can be received remotely. In case a PSTN modem or a mobile isconnected, automatic alarm messages can be received.

The data transfer between the control module and the motherboard is made via theI2C-Bus system.

The I2C-Bus concept was developed by Philips for the serial connection of integratedcircuits within one device. Two wires, serial data (SDA) and serial clock (SCL), carryinformation between the devices connected to the bus. Each device is distinguishedby a unique address and can operate either as transmitter or receiver.

All configuration parameters are non-volatile stored in an EEPROM on the controlmodule if power supply failure occurs.

3.3.7. Connecting Board

The connecting board ismounted on top of the duplexerand serves as an interface forthe mains cable and forexternal alarms, summaryalarms, and the optional PSTNmodem.

In repeaters providing theVSWR option the voltage forthe VSWR module is fed viathe connecting board.

figure 3-11 Connecting board

3.3.8. Motherboard

The purpose of the motherboard is to enable communication between the conversionmodule and the control module via the I2C-Bus and the support of all necessary DCvoltages and connections. All signals will be acknowledged by the motherboard logic.The motherboard is located underneath the conversion modules.

M0079A0D.doc

3.4. OPTIONAL EQUIPMENT

The actual repeater configuration can be seen at the configuration list, which is partof the delivery.

3.4.1.1. Modem

The modem option enables the provider to set parameters and to query the status ofeach repeater by remote control. Furthermore, the modem can be set to send allalarms occurred in 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 SwitchedTelephone Network). Thus, the alarms can be evaluated and eliminated promptly. Itis possible to install the wireless modem or the PSTN modem on site!

ò Check the communication mode between the modem and the terminal. Ifnecessary, 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 differentmodem is required or if the quality of the line does not allow to use the setparameters, the settings have to be changed in PC mode. The same applies for allother parameters which can be set previously for modem mode by software.

3.4.1.2. Initstrings

Depending on the provider’s network and the used modem type, it is necessary toadjust the initstring. The following initstrings are factory set:

3.4.2. VSWR (Voltage Standing Wave Ratio)

The VSWR option is available for GSM900 and GSM1800, only. This feature enablesthe provider to query the status of the antenna system (antenna & cable). The VSWRmodule measures the voltage standing wave ratio of the DL output antenna port. If acable is defect or the antenna is covered with ice, the VSWR will get worse.

If the VSWR falls below approximately 13 dB, an alarm is released. The alarm can beforwarded to the OMC where the faults and irregularities can be acknowledged andeliminated promptly. The VSWR module can not be installed on site.

figure 3-16 VSWR module, location in the F-cabinet

3.4.3. ICE (Interference Cancellation Equipment)

figure 3-17 ICE module

VSWR module


M0079A0D.doc

ICE has been developed for channel selective and CDMA repeaters only, to enhancethe antenna isolation. This feature enables repeater to provide coverage in areaswhere they were previously not effective due to physical site limitations which causedinsufficient antenna isolation.

Antenna isolation is the RF loss measured between the donor antenna and thecoverage antenna. If the gain of the repeater exceeds the path loss, feedback in formof oscillation occurs. The isolation is usually dominated by the direct path loss fromone antenna to the other, but reflections can contribute to or even affect antennaisolation. ICE cancels the signal from the primary feedback path, thus allowing thegain of the repeater to be increased.

The ICE option can be installed on site but it is recommended to have the ICEmodules installed at the factory for better optimization of the repeater.

There are different types of ICE modules, their application depending on the requireddelay resulting from on-site conditions. The following figure shows the delay independence of the cable length and the distance between the antennas.

3.4.4. External Alarms

With the external alarms option, it is possible to monitor the status of connecteddevices via the repeater software, e.g. a UPS. The DIP-switches of the Ext.-Alarmsswitch on the control module have to be set to position ON “Ext. Alarm 1-4”. The DIP-switch settings are factory-set and should not be changed. For details, see chapter9.5 DIP-Switch Settings.

The connecting clamps are located on the connecting board mounted on theduplexer (BTS side).

figure 3-19 Location of external alarm clamps

All external alarms are normally high (5V) without connection. Via the softwarecommand 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 alarmsare set to low active, otherwise the status will always show an alarm.

F Note: The name for each external alarm and the name for the alarmmessage can be defined by the customer with the correspondingsoftware command (see software manual).

F Note: A special software blocking must be removed to use the externalalarm option. This can only be carried out by authorized personsfrom Mikom.

3.4.5. Battery Backup

Battery backup is provided for the control module to transmit alarm information incase of power failure. The battery type is a NiCd 8.4V/300 mAh. The battery backupis sufficient to support multiple dial out attempts via modem in case of ‘systemengaged’ or other communication problems for at least ten minutes under normalenvironmental conditions.

The batteries are protected from deep discharge by use of a low voltage disconnectunit. A local switch is provided to disconnect the battery backup option duringmaintenance to ensure that all circuits are voltage-free. For the location of the switchrefer to chapter 8.2.11 Battery Backup Module.

The module is directly plugged into the control module. During the charging processa 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.

M0079A0D.doc

4.2. ELECTRICAL INSTALLATION

4.2.1. General

Read the health and safety warnings in chapter 1.2 Health and Safety Warnings.

1. This unit contains dangerous voltages. Loss of life, severe personal injuryor property damage can be the result if the instructions contained in thismanual are not followed.

2. It is compulsory to ground the unit before connecting power supply. Agrounding bolt is provided on the cabinet to connect the ground bondingcable.

3. Although the repeater is internally protected against overvoltage, it isstrongly recommended to earth the antenna cables close to the repeater’santenna connectors for protection against atmospheric discharge. In areaswith strong lightning it is strongly recommended to insert additionallightning protection.

4. Hard wired installation of mains supply for the repeater requires an easilyaccessible separation device in the mains circuit.

5. Make sure that an appropriate circuit breaker and an overcurrent limitingdevice are connected between mains and repeater.

6. A connection of mains supply to a power socket requires the power socketto be nearby the repeater.

7. The repeater might be supplied from IT mains. (The maximum nominal lineto line voltage must not exceed 400VAC).

8. Incorrectly wired connections can destroy electrical and electroniccomponents.

9. To avoid corrosion at the connectors caused by electrochemical processes,the material of the cable connectors must not cause a higher potentialdifference than 0.6V (see electrochemical contact series).

10. It is sufficient to tighten the 7/16 or N antenna connector hand-screwed. Anyuse of a tool (e.g. pair of pliers) might cause damage to the connector andthus lead to malfunctioning of the repeater.

11. For unstabilized electric networks which frequently generate spikes, it isadvised to use a voltage limiting device.

12. Observe the labels on the front panels before connecting any cables.

ID No: 151997

4.2.2. Grounding

Grounding must be carried out. An earth bonding cable must be connected to thegrounding bolt provided at the outside of the cabinet on the left-hand side. Do not usethe grounding screw for connecting external devices. The complete grounding kit ispart of the delivery schedule.

figure 4-3 Grounding bolt

4.2.3. Power Connection

Before connecting electrical power to the repeater, it must be grounded. The repeateris equipped with a firmly connected mains cable which is fed into the housing througha watertight cable gland. Due to safety reasons, the power supply lead must beprotected by fuses. Inside the repeater, the mains cable is connected to a screwterminal on the connecting board. In case the length of the power cable should not besufficient, it can be replaced by a longer cable.


M0079A0D.doc

4.2.4. Connection of the Antenna Cables

The repeater has female antenna connectors 7/16 (N as an option) located on thelower side of the cabinet. For mounting the cable connectors, it is recommended torefer to the corresponding documentation of the connector manufacturer. Thebending radius of the antenna cables must remain within the given specifications.

For the selection of cable and antenna some points should be considered. A cablewith higher loss is less expensive but on the other hand it impairs performance.Highly directional antennas providing a good front-back-ratio are recommendable asdonor antenna to the BTS because they increase isolation.

It is sufficient to tighten the 7/16 (or N) connectors hand-tight. The useof a tool (like pliers) may cause damage to the connector and therefore,lead to a malfunctioning of the repeater.

5. COMMISSIONING

5.1. GENERAL

Read the health and safety warnings in chapter 1.2 Health and Safety Warnings aswell as the description carefully to avoid mistakes and proceed step by step asdescribed.

Ø Do not operate the repeater without termination of the antenna connections.The termination can be achieved by connecting the antennas, a dummy loador the 50-Ohm-terminated connection of a measuring instrument.

Ø To ensure safety, the electrical and subsequent installations, commissioningand maintenance activities that require the unit to be under power while open,must only be carried out by suitably qualified personnel.

Ø When opening the repeater, do not damage the seals on the devices insidethe repeater. Warranty void if the seals are broken.

F Note: Each connected extension unit must be switched on before themain unit! Otherwise the extension unit(s) will not be recognizedby the control module of the main unit, which scans the systemduring the boot process.

5.2. ANTENNA ISOLATION

Before setting the parameters of the repeater, ensure that the antenna isolation ismeasured and optimized. The gain margin (GM) between the antenna isolation andthe actual gain of the repeater is specified to 15 dB for all RF-repeaters, i.e. the gainhas to be 15 dB less than the measured value of the antenna isolation.

Example:

Antenna isolation: 80 dBGM: - 15 dB

-------------Allowed max. gain: 65 dB

In this case, the antenna isolation should be improved. The operator has to enlargethe distance between both antennas or has to shield the antennas against eachother, which is not always possible.

The ICE option has been designed for (channel selective & CDMA) RF repeaters tosolve the antenna isolation problem. The GM between the antenna isolation and themaximum gain is specified to -4 dB, i.e. gain can be set 4 dB higher than the isolationvalue of the antennas.


M0079A0D.doc

• Repeater with ICE option

Antenna isolation: 80 dBGM with ICE option: +4 dB higher

----------------------Allowed max. gain: 84 dB

For further details to ICE or antenna isolation, please refer to Mikom “ApplicationNote for Antenna Isolation” or “ICE Datasheet”.

5.3. BCCH-CHANNEL

It is necessary to measure the BCCH level (BCCH=Broadcast Control Channel). Theresulting max. allowed repeater gain of the antenna isolation must be compared withthe resulting max. allowed repeater gain of the measured BCCH channel. The lowergain has to be set for the repeater.

The following example illustrates how to set the correct gain:

Antenna isolation:Antenna isolation: 100 dBGain Margin (GM)*: 15 dB

-------------Allowed max. gain: 85 dB

BCCH channel:Power out: +30 dBmReceived level of BCCH: -(-40) dBm

----------------Allowed max. gain: 70 dB

* Refer to chapter 5.2 Antenna Isolation for further information about GM.

In this case, 70 dB gain has to be set for the repeater.

F Note: If a higher gain is set, the ALC will be active. This might affect thequality of the signal.

Common

6. ALARMS

6.1. BITE AND ALARMS

The Built-In Test concept comprises the monitoring of the power supplies, themotherboard and the remote control interface. Furthermore, the synthesizer lock andthe 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 thesoftware command “ALARMACKN”, e.g. ALC active, RSSI, door open or stabilitycontrol. If all alarms have been acknowledged, the summary error LEDs are set backto green indication.

If monitored via a modem, automatic dialling will generate a summary alarmmessage. The provider can acknowledge the alarm message and can request adetailed status report.

6.2. HANDLING OF ALARMS

As soon as the software acknowledges a valid alarm, a message is transmitted to theoperator. In remote mode, the alarm can be acknowledged by simply ringing backand typing ALARMACKN.

If the reason for the alarm has been cleared or if the alarm should continue, a newalarm message will not be repeated. If there was an interruption of at least onesecond after acknowledgement, a new alarm message will be generated.

6.3. SUMMARY ALARM RELAY

The summary alarm relay is a potential-free relay. It canbe used to monitor alarms with an external alarmindicator. Devices connected to this relay must notexceed a maximum switching power of 12Vdc, 0.125A.For the location of the connecting clamps of thesummary alarm relay please see chapter 3.4.4 ExternalAlarms.


M0079A0D.doc

6.4. 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 canbe monitored only, but not influenced by SET commands.

The complete listing of the syntax with the processor of the control module includingthe instructions and the messages as well as all available alarms from the system isavailable as a separate software manual.

8 Maintenance

ID No: 151997

8. MAINTENANCE

8.1. GENERAL


F Note: The repeater does not require preventative maintenancemeasures.

It is only recommended to replace the RTC battery and - if installed - the battery packof the battery backup module after three years of usage as a preventive measure.The nominal lifetime of these batteries is five years under normal environmentalconditions.

F Note: The RTC battery must be removed for long term storage.

In the event of malfunction, it is advantageous to check the status of the antennasystems as well as the continuity of the entire cabling including connectors beforereplacing any components.

8.2. REPLACEMENT OF COMPONENTS


Maintenance on the repeater shall be performed by replacing components only.Soldering on printed circuit boards must be avoided. In order to maintain warranty,take care not to damage unintentionally the seals on the components. To open thehousing, the upper screws have to be removed first and then the lower screws.Proceed in reverse order to close the housing.

The spare parts list, consequently, contains only units which can be replaced withouttuning or complex soldering work. Those units are all Mikom parts as well as internaland external cables.

F Note: Defect parts should only be replaced by original parts from Mikom.All interventions inside the housing are at one’s own risk.

F Note: During maintenance ensure that the repeater has beendisconnected from mains and that - if installed - the batterybackup module has been switched off/unplugged.

Open the lock at the left-hand side of the repeater. Use a torx key and unscrew thefour torx screws.

F Note: Before disconnecting any cables, label any unlabeled cables toensure correct reconnection, and check the switch positions of theremoved part to set the switches of the new part accordingly.

F Note: Depending on the repeater configuration some components areequipped with a 50-Ohm termination resistor. In such a case, usethe termination resistor of the removed part to terminate therespective connector of the replacement part.


M0079A0D.doc

For most maintenance procedures appropriate tools are required to ensure correcthandling. All these tools can be ordered from Mikom. For screwing proceduresobserve that all our screws have a right-hand thread, i. e. for fastening the screwsturn the tool clockwise and for unscrewing them turn it counter-clockwise. For SMAconnectors a specified torque of 100 Ncm has to be observed. Therefore, use anappropriate tool. Also, specified torques have to be observed for screws, dependingon the screw type and thread.

The table below shows a survey of the various screws with their respective torques.In order not to exceed these torques, use appropriate tools for screwing procedures.

F NOTE: Each duplexer is equipped with an amplifier at its backside. Do notseparate the two parts. The new duplexer will be supplied with apre-mounted amplifier.

Ø If a conversion module is located opposite the duplexer, it has to be removed inorder to get access to the SMA connectors. To do so refer to chapter 8.2.2Conversion Module.

Ø To remove the duplexer, first disconnect all cables and SMA connectors from theduplexer (and amplifier).

Ø Unscrew the four countersunk head screws M3x10 by which the duplexer isfastened to the connector panel of the repeater (see figure 8-1 Duplexer, positionof screws).

Ø Take the duplexer out completely, making sure that the black seal between theduplexer and the connector panel of the cabinet is also removed.

Ø A new seal is supplied with the new duplexer, therefore, we recommend to throwthe old seal away immediately, in order to avoid confusion.

Ø IMPORTANT: Before starting to mount the new duplexer make sure to have putthe new seal– the one that was delivered with the new duplexer – correctly onthe surface of the duplexer that is fitted on the connector panel of the cabinet. Theleft and right edge of the seal must be level with the left and right edge of thesurface. The position of the seal is not correct if part of it stands out at the bottom.

Ø Fasten the duplexer with the four countersunk head screws M3x10 to theconnector panel of the repeater and reconnect the SMA connectors.

Ø Install the VSWR module according to chapter 8.2.10 VSWR Module if thismodule was mounted on the duplexer.

Ø To mount the conversion module refer to chapter 8.2.2 Conversion Module, then,reconnect all cables and SMA connectors to the duplexer (and amplifier).

8.2.2. Conversion Module

Ø If an ICE or an VSWR module – both optional features – are placed on top of theconversion module, they have to be removed first according to chapter 8.2.12 ICEModule or chapter 8.2.10 VSWR Module, respectively.

Ø To remove the conversion module, disconnect the SMA connectors and unscrewthe six socket head cap screws M3x30.
