User’s manual for channel selective repeater MRx41M0090a0a.doc Id.-No. 148092 Page 13 29-Mar-001 Introduction1.1 Intended purposeCellular telephone systems transmit signals in two directions between base stationsand mobile telephones 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 path the repeater will pickup thesignal from a donor antenna of an existing cell, amplifies and re-transmits it into thedesired dark spot. In the uplink direction the repeater will receive signals frommobile stations present in its coverage area and re-transmits them to thecorresponding base station.1.2 About the MRx41The repeater MRx41 is a channel selective amplifier, which bi-directionally amplifiessignals between mobile stations and a base station in the GSM900, GSM1800 undPCS1900 mobile telephone system. It can provide highly selective amplification ofup to 8 channels, thus enabling radio coverage in regions where satisfactory qualityof communication is disabled.MRx41 modules can also be combined with other MRx41 repeater modules in orderto create a combines GSM900, GSM1800 or PCS1900 repeater system. Othermodules, operating in TACS, ETACS and AMPS are available as well. Whendifferent modules are combined, a common antenna terminal and a common controlinterface is available. The basic unit is capable of 2 channels and easily expandableby adding 2-channel extension units delivered in separate cabinets.The repeater can be set locally or remotely. For modem operation differentinterfaces are available. The design of the repeater comprises a large number offunctions which the operator may monitor via terminal emulation program or theMikom OMC software platform. An easy to understand and easy to learncommunication language supports the operator to query status reports from therepeater or to change settings.F Note: It is not possible to combine MRx41 units / modules with MRx40 units/ modules.

User’s manual for channel selective repeater MRx41M0090a0a.doc Id.-No. 148092 Page 18 29-Mar-002.1 Channel modulesTwo different types of conversion modules have been designed.1. Basic module: Channel 1, 3, 5 and 72. Extension module: Channel 2, 4, 6 and 8figure 2-7 Top view of basic / extension moduleThe repeater consists of two amplifier chains, which are connected antiparallel. Thereceive path of one direction is connected to the transmit path of the other directionby a frequency separation unit, in the following denominated as a duplexer, whichcombines both signals to an antenna.The task of the conversion modules is to amplify the receive signals and to convertthem into an intermediate frequency. The signals, then, proceed a filter stagecomprising of highly selective filters, and run through a digital controllableattenuator. The attenuation can be set in steps of 2 dB, locally or remotely. By usingthe same synthesizer frequency, that was used to convert the signals down tointermediate frequency, the intermediate frequency is mixed up to the originalfrequency.The synthesizer is controlled via an I²C-Bus. In case of a breakdown in mains, gainand frequency data are non-volatile stored in an EEPROM on board.BasicmoduleExtensionmodule
User’s manual for channel selective repeater MRx41M0090a0a.doc Id.-No. 148092 Page 19 29-Mar-00The filters of the MRx41 series have the bandwidth of a GSM900; GSM1800 orPCS1900 channel.The RF output is protected by limiting the output power with an ALC circuitry insidethe module.High stability against intermodulation is achieved by isolators before and after thecombiner amplifiers, which inhibits crosstalk into the other amplifier path, thuspreventing the generating of parasitic mixing products. The combiner is followed bya duplexer.F Note: For the exchange of a channel module or the installation of a newchannel module, the slave address of the synthesizer has to beset ( see chapter 8.8).2.2 Termination moduleTo install a repeater system with an odd channel number ( e.g. 1, 3, 5 or 7 channels) a termination module has to be installed instead of an extension module. This isnecessary in order to keep the gain balance, otherwise the last channel provides 3dB more gain and output power.figure 2-8 Mounting drawing of the termination module
User’s manual for channel selective repeater MRx41M0090a0a.doc Id.-No. 148092 Page 20 29-Mar-002.3 Mother boardThe function of the mother board is the communication between the conversionmodules and the control module via the I²C-Bus but also the support of all necessaryDC voltages and connections. All signals are recognized from the mother boardlogic. Furthermore each repeater unit has an allocated address set by means of arotary switch. The address of the repeater has been set already in the factory. Therotary switch is located on the left-hand side of the mother board on top of the board.F Note: Don’t adjust this switch unless it is necessary.Configuration of the rotary switch to set the address of the repeater unit.0 = Main Unit  ( channel 1 and 2 )1 = Extension Unit 1 ( channel 3 and 4 )2 = Extension Unit 2 ( channel 5 and 6 )3 = Extension Unit  ( channel 7 and 8 )4...F Do not use!figure 2-9 Top view of the mother boardMother boardRotary switchto set addressof repeater unitDIP-Switches toactivate theextension I²C-BusOFFON
User’s manual for channel selective repeater MRx41M0090a0a.doc Id.-No. 148092 Page 21 29-Mar-002.4 Control module SM2009The control module SM2009 is a DOS compatible micro computer. The wholecommunication between the operator and the repeater can be done via the controlmodule. By using either the RS232 interface or the PCMCIA slot and a mobile therepeater can be controlled locally or remotely by using a VT100 terminal, or a PCemulating the VT100 terminal.Gain of uplink and downlink can be controlled, channels can be set and statusmessages can be received remotely.The data transfer between the control module SM2009 and the mother board isrealised by the I²C-Bus.The I²C-Bus concept was developed by Philips for the serial connection of integratedcircuits within one device. Two wires, SDA - serial data and SCL - serial clock, carryinformation between the devices connected to the bus. The MRx41 I²C-Bus conceptis working with a bit rate of 1.5 kbit/s. All configuration parameters are stored non-volatile in an EEPROM on the control module, so that in case of a power supplyfailure all user settings can be restored completely.

The passbandwidth of the duplexer is the required width of the uplink band and the downlinkband respectively in the GSM1800 and PCS1900 band.2.6 CombinerAfter passing through the final stage the signals of all channel groups will becombined from the combiner module in the UL and in the DL path. The combiner isonly equipped from 3 channels up to 8 channels.and will be followed by theduplexer. A combiner is not required in an one or two channel repeater.2.7 Measuring aidsWith the built-in RF probe signals can be applied or detected. The probes provide acoupling factor of 30 dB. This facilitates measurements under all operationalconditions, while an antenna or a dummy load may be connected. Each duplexer isequipped with one coupler.2.8 Power supplyThe power supply is provided by 230 Vac (optionally 115 Vac or 48 Vdc or 24 Vdc)mains power. The following figure shows the mounting position of the power supplyin the repeater lid. The secondary voltage is + 8 Vdc for the channel modules andthe mother board logic, + 12 Vdc for the control module.The power supply can beswitched on or off by means of an external switch. The modules of the repeater arevoltage free if the power supply is switched off.F Note: To switch the whole repeater voltage free, you have to disconnectthe power lead from mains.The power supply is factory-set ( with load ) to the following voltages and must notbe changed:•   7.8 V ± 0.1 V• 12.4 V ± 0.1 V

User’s manual for channel selective repeater MRx41M0090a0a.doc Id.-No. 148092 Page 28 29-Mar-003.3 ALCIn order to protect the amplifiers from overload and to prevent the system togenerate spurious emission, the amplifiers have an Automatic  Level  Control,designed to limit the output power to a constant value ( max. output power ). A partof the output power is decoupled, rectified, amplified and used to control anattenuator network in the conversion modules. In order to avoid oscillation, thecontrol amplifier has an integrating characteristic.The threshold for the ALC can be set manually for each motherboard. The ALCsettings affect both modules on the motherboard for UL and DL separately. The ALCthreshold will be set in the factory and can be found on the test data sheet of therepeater In case a new module will be mounted or a module will be exchanged thevalues for the ALC threshold in each link have to be compared. In case they aredifferent the higher value has to be set. An increase of the input signal results in anincrease of the output signal. If the output power exceeds the required power, anALC alarm is triggered.3.4 BITE and alarmsThe  Built-In  TEst concept comprises the monitoring of the power supplies, theoperational currents in the conversion modules, the mother board and the remotecontrol interface. Furthermore the temperature of  the repeater is monitored.There are three multicoloured LEDs mounted on the control module. The LED L3indicates the presence of +12 Vdc in the repeater. Every alarm is indicated by failureLEDs, L1 and L2 together ( simultaneously ), mounted on the control module ( seechapter 2.4 ).In case a hardware failure is detected the concerning hardware module has to bereplaced.

User’s manual for channel selective repeater MRx41M0090a0a.doc Id.-No. 148092 Page 30 29-Mar-003.4.1 Handling of alarmsAs soon as the software recognises a valid alarm, a message can be transmitted tothe OMC.If the repeater is operating in modem mode the alarm message ‘MIKOM>REPEATER REQUIRES OPERATOR ATTENTION’ will be sent via modem to theterminal or the OMC. The first of two stored telephone numbers will be dialled. Incase a connection cannot be established the second telephone number will bedialled. 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 ( pollingprincipal ). To decide whether an alarm is a valid alarm it must remain for 5 pollingcycles, only then it will be recognized and entered in the alarm history. As soon asthe 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. TheseLEDs are mounted on the control module ( see figure 12-3 ).   The entry in the alarm history describes the alarm type, the time and the date whenit 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 andtyping a software command. It is also possible to acknowledge alarms in localmode. Acknowledged alarms will be indicated with ‘-ACK’. As soon as the alarmshave been acknowledged the alarm relay will be reset and the summary LEDsswitch back to green light again.If the same alarm cause occurs again, it will be entered in the alarm list ( notacknowledged ) after 5 polling cycles. An already acknowledged alarm must havean interruption of at least 5 polling cycles to be detected by the software as a newalarm. Only then the alarm will be entered again in the alarm history ( notacknowledged ). There exists no command to delete the alarm history.The alarm list has a capacity of about 50 alarm entries. If more alarms occur theoldest message will be deleted first ( FIFO principle ).In the software exists no alarm clear message, i.e., the repeater sends no messageto the terminal or the OMC if an alarm has disappeared by itself.

The severity levelsindicate 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 hasoccurred and an immediate corrective action is required to restore thecapability of the managed object.- Major: The major severity level indicates that a service affecting condition hasdeveloped and an urgent corrective action is required. Such a severitycan be reported, for example, when there is a severe degradation in thecapability of the managed object and its full capability must be restored.- Minor: The minor severity level indicates the existence of a non-service affectingfault condition and that corrective actions should be taken in order toprevent a more serious failure. Such a severity can be reported, forexample, when the detected alarm condition is not currently degradingthe capability of the managed object.- Warning: The warning severity level indicates the detection of a potential orimpending service affecting failure before any significant effect has beencaused. Action should be taken to further diagnose and correction of theproblem shall prevent a more serious service affecting failure.- Disable: The disable severity level indicates that the detected failure has noinfluence on the system and shall not be sent to the terminal or the OMC.F Note:  No entry in the alarm history.

If the VSWR falls below approximately 13 dB an alarm is released.This enables the provider to know the status of the cable to the antenna. If a cable isdefective the VSWR will decrease and the alarm will be released. The alarm can beforwarded to an OMC, so that faults and irregularities can be recognised andeliminated rather quick.Technical data:VSWRMeasuring range 5 to 15 dBFrequency range: whole frequency range of the repeater• 925 to 960 MHz in GSM900/EGSM• 1805 to 1880 MHz in GSM1800• 1930 to 1990 MHz in PCS1900Alarm if VSWR < 13 dB ± 1 dBRequirements:The VSWR option can be implemented in each MIKOM repeater. ( Installation of theoption on site not possible! )4.5 Traffic statistic moduleThe traffic statistic module is available for MIKOM repeaters, working channelselective in the uplink path. With this option the network operator gets statisticalinformation about the efficiency and traffic load of the repeater operating in thenetwork. The processing and evaluation of the data takes place in the controlmodule of the repeater together with the required software.F  Note: Traffic will be measured for each channel separately.The software reads in defined time intervals whether there is a signal above aspecified threshold level on the respective channels or not. This data is assigned todefinite values and these values are read till the next full hour. An average value isthen created and stored in a data list. Date and time of the measurement is givenwith this list as well. When executing the respective command the list shows thetraffic load in percent for each hour of the day which is also called performancedata.

User’s manual for channel selective repeater MRx41M0090a0a.doc Id.-No. 148092 Page 41 29-Mar-004.6 ICE moduleICE has been developed to enhance the antenna isolation. This feature enablesrepeaters to provide coverage in areas where they were previously not effective dueto physical site limitations, which caused insufficient antenna isolation. Antennaisolation is the RF loss measured from the donor antenna to the coverage antenna.The path between these two antennas is a limitation on the repeater. If the gain ofan on-frequency repeater exceeds the path loss, feedback in the form of oscillationoccurs. The isolation is usually dominated by the direct path loss from one antennato the other, but multipath can contribute to or even dominate antenna isolation. ICEcancels the signal from the primary feedback path, thus allowing the gain of therepeater to be increased.For the installation of a repeater with the ICE module it is unnecessary to measurethe antenna isolation.Different types of ICE modules exist depending on the installation delay option. Thefollowing table displays the delay in dependence on the cable length and thedistance between the antennas.1. If it is possible to calculate the total cable length, the customer can choose theICE module with the corresponding delay option.2. If it is not possible to calculate the total cable length it is possible to choose theICE module with all possible delay options.figure 4-7 Cable length and antenna spacing

The mounting hardwareused is specific to the type of installation. The unit should be positioned so that it isin a secure location, yet easily accessible for maintenance. There should be enoughclearance ( 1 m radius ) for the door to swing completely open and electrical andother connections should be easily accessible. Also note that the bend radius of thecables should not be exceeded when positioning the unit. The repeater shall bemounted in the vertical plane to a wall or a mast, which means the connectors haveto show down to the bottom.figure 5-2 Clearance distanceUse the mounting brackets, which are part of the delivery. This will guarantee aminimum distance between the wall and the repeater housing. The mountingbrackets must be fixed with 4 screws to the wall ( brackets ) and the cabinet mustbe fixed with 4 hex socket screws and 2 tyre screws to the mounting brackets.Check the correspondence of the wall mounting kit and the wall.F Note: Due to power dissipation the repeater may heat up the air volumeinside the cabinet and reaches a very high temperature. Therefore itis necessary to mount the repeater in the vertical plane to a wall or amast without additional enclosure to provide sufficient ventilation.Between the housing and the wall a minimum distance must be keptin order to provide air circulation.F Note: The weight of the MRx41 is approx. 14 kg in standard configuration.

User’s manual for channel selective repeater MRx41M0090a0a.doc Id.-No. 148092 Page 60 29-Mar-007.5 General remarks• After a software download previous user settings ( data default values ) might beoverwritten. Before you start a software download save all user settings:- ARFCN numbers- attenuation- ALC threshold- temperature compensation offset ( gain )- phone numbers etc.• If an ALC alarm occurs during installation or commissioning an user error mightbe the cause, due to wrong measurements, e.g.ALC: Input level too high à reduce gain• RSSI: Input level too low à check antenna and cables andattenuators• Traffic statistic: Measurement is never zero, it is displaying continuouslyvalues evenin periods of low traffic loads, e.g. during night.Cause: Traffic threshold ( factory setting -95 dBm ) is too low. Thetraffic module is then measuring only noise.Solution: Threshold has to be increased ( contact factory ).
