2 Introduction

2. INTRODUCTION

2.1. PURPOSE 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 signals from a donor antenna of an existing cell, processes and retransmits them into the desired dark spot. In the uplink (UL) direction, the repeater receives signals from mobile stations present in its coverage area and forwards them to the corresponding BTS.

2.2. THE MR1934 REPEATER The MR1934 repeater 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 variable bandwidth module can be adjusted from a minimum bandwidth of 200 kHz to the specified maximum. Defined signal bandwidths can be set by the user to maximize the amplification of the desired signals. The MR1934 can be easily configured via an RS-232 serial port. The repeater has a large number of functions that can be monitored and changed by the operators via a terminal emulation program. 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.

3 Functional Description

3. FUNCTIONAL DESCRIPTION

3.1. GENERAL The repeater consists of two amplifier chains, which are connected anti-parallel. The receiving path of one direction is connected to the transmitting path of the other direction by a frequency separation unit, in the following denominated as duplexer, which combines both signals to an antenna. After the duplexer, the signals pass through a pre-amplifier and afterwards through a conversion module. The task of the conversion modules is to amplify the received signals and to convert them into an intermediate frequency. The signals, then, proceed a filter stage comprising highly selective filters, and pass through a digitally controllable attenuator. The attenuation can be set, locally or remotely, in steps of 2 dB. By using the same synthesizer frequency that was used to convert the signals down to intermediate frequency, the intermediate frequency is converted back into the original frequency. Then, the signals are amplified by the final amplifier, which provides the required output power. The following figure shows the configuration of an MR1934 repeater.

figure 3-1 Configuration of an MR1934


M0096A1C.doc

3.2. FACTORY SETTINGS All motherboards and conversion modules are coded. Generally the settings are factory-set. The settings are defined and must be kept in case of an upgrade of the repeater or a replacement of parts. The following figure shows the repeater settings of each motherboard and conversion module.

3.3. COMPONENTS OF THE MR1934 The actual configuration of the repeater can be seen at the configuration list, which is part of the delivery.

3.3.1. Duplexer The task of the duplexer is to isolate UL from DL, 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.

M0096A1C.doc

With built-in RF probes at the duplexers, test signals can be applied or detected. The probes are provided with different coupling factors, 30 dB for measurements and 20 dB for the optional modem. This facilitates measurements under all operational conditions 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 convert them into an intermediate frequency. Then, the signals pass a filter stage comprising highly selective filters and after that they go through a digitally controllable attenuator.

figure 3-5 Conversion module

Each link of a conversion module is provided with filters where the desired bandwidth can be set. By using the same synthesizer frequency that was used to convert the signals down to the intermediate frequency, the intermediate frequency is converted back into the original frequency. The synthesizer is controlled via an I2C-Bus.


3.3.3. Final Amplifier The UL/DL paths are amplified by a final amplifier. It is located next to the conversion module.

figure 3-6 Final amplifier

3.3.4. 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 motherboard is made via 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 distinguished between by a unique address and can operate either as transmitter or receiver.


M0096A1C.doc

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

figure 3-7 Control module

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

figure 3-8 Motherboard


3.3.6. Connecting Board The connecting board is mounted on top of the duplexer and serves as an interface for the mains cable and for external alarms, summary alarms, and the optional PSTN modem.

figure 3-9 Connecting board

3.3.7. Power Supply The power supply transforms the input power from mains into a defined DC voltage by which all active components of the repeater are supplied. An external switch, mounted on the power supply, is provided to disconnect the repeater from mains during maintenance work to ensure that all circuits are voltage-free. The power supply is factory-set and must not be changed. The power supply can be fuse-protected.

M0096A1C.doc

3.4. OPTIONAL EQUIPMENT The actual repeater configuration can be seen at the configuration list, which is part of the delivery.

3.4.1. Modem The modem option enables the provider to set parameters and to query the status of each repeater by remote control. Furthermore, the modem can be set to send all alarms occurred in the repeater directly to a provider’s terminal, e.g. to the OMC. This can either be done 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! ò 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 using the set parameters, the settings have to be changed in PC mode. The same applies to all other parameters which can be set previously for modem mode by software.

3.4.1.1. 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: Modem Network Initstring

Siemens MC35 GSM900/1800/EGSM ATE0S0=1S7=60 &D2+CBST=7,0,1

Siemens MC45 / MC46 *

GSM850/1800/1900

table 3-2 Standard initstrings for modems For further details to the initstrings, please refer to the software manual.


3.4.1.2. PSTN Modem

A Hayes compatible PSTN modem can be connected to the control module SM2009. The telephone cable has to be fed through a labelled grommet of the connector panel and must be connected to the designated clamps (see chapter 3.4.2 External Alarms).

Note: If a PSTN modem is required, the DIP-switches of the External-Alarms switch [4] on the control module* have to be set to position OFF “PSTN Modem”. The DIP-switch 2 of the Mode-switch [1] has to be set to position ON “Remote Mode”.

figure 3-11 Location of PSTN modem kit * The DIP-switch settings are factory-set and should not be changed. For details, see chapter 9.5

DIP-Switch Settings. For any further information, please refer to the Installation Guide for the PSTN modem.


M0096A1C.doc

3.4.1.3. Wireless Modem The optional wireless modem (MC35 or MC46) enables the remote control and maintenance of a repeater. Parameters can be set, status information can be queried and alarms can be forwarded to the OMC software platform.

3.4.2. 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 external-alarms switch 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 chapter 9.5 DIP-Switch Settings. The connecting clamps are located on the connecting board mounted on the duplexer (BTS side).

figure 3-14 Location of external alarm clamps All external alarms are normally high (5 Vdc) 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 5 Vdc / 0.5 mA. When only two external alarms are required, ensure that the other two 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 Andrew Wireless Systems.


M0096A1C.doc

3.4.3. Battery Backup Battery backup is provided for the control module to transmit alarm information in case of power failure. The battery type is NiCd 8.4 V / 300 mAh. The battery backup is sufficient 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. 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. For the location of the switch refer to chapter 8.2.9 Battery Backup Module. 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.

Although the repeater is internally protected against overvoltage, it is strongly recommended to earth the antenna cables close to the antenna connectors of the repeater for protection against atmospheric discharge. In areas with strong lightning it is strongly recommended to insert additional lightning protection.

4. Hard-wired installation of mains supply for the repeater requires an easily accessible disconnect device in the mains circuit.

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

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

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

8. Incorrectly wired connections can destroy electrical and electronic components.

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

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

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

4 Installation

12. The unit complies with the surge requirement according to EN 61000-4-5 (fine protection); however, it is recommended to install an additional medium (via local supply connection) and/or coarse protection (external surge protection) depending on the individual application in order to avoid damage caused by overcurrent.

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

4.2.2. Grounding Grounding must be carried out. An earth-bonding cable must be connected to the grounding bolt provided at the outside of the cabinet on the left-hand side. Do not use the grounding screw for connecting external devices. The complete grounding kit is part 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 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.


M0096A1C.doc

4.2.4. Connection of the Antenna Cables The repeater has female antenna connectors 7/16 (N as an option) located on the lower side of the cabinet. For mounting the cable connectors, it is recommended to refer to the corresponding documentation of the connector manufacturer. The bending radius of the antenna cables must remain within the given specifications. For the selection of cable and antenna some points should be considered. On the one hand, a cable with higher loss is less expensive but, on the other hand, it impairs performance. Highly directional antennas providing a good front-back-ratio are recommendable as donor antenna to the BTS because they increase isolation.

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

5 Commissioning

5. COMMISSIONING

5.1. GENERAL Read the health and safety warnings in chapter 1.2 Health and Safety Warnings as well as the description carefully to avoid mistakes and proceed step by step as described.

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

To ensure safety, the electrical and subsequent installations, commissioning

and maintenance activities that require the unit to be under power while open, must only be carried out by suitably qualified personnel.

When opening the repeater, do not damage the seals on the devices inside

the repeater. Warranty void if the seals are broken.

Note: Each extension unit connected must be switched on before the main unit! Otherwise the extension unit(s) will not be recognized by the control module of the main unit which scans the system during the boot process.

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

5.3. BCCH-CHANNEL It is 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 illustrates how to set the correct gain: Antenna isolation:

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

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


M0096A1C.doc

BCCH channel:

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

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

* Please 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.

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

5.4. BOOT PROCESS After the repeater is switched on, the control module of the repeater starts the boot process; LE3 displays “Power on”. The initialization of the hardware is part of the boot process. The whole process may take up to several minutes. After booting the system, LE1 turns red for a few moments, then flashes green. LE2 also flashes red and then green. This is just an optical functionality test of the two-coloured LEDs.

5.6. SETTINGS VIA SOFTWARE After the boot process, the software login is possible. All parameters of the software can be changed by the provider to optimize the repeater according to the network system. There are two possibilities how to login to the software:

locally, via a VT100 terminal or a PC with VT100 terminal emulation remotely, via a modem e.g. with the Operation and Maintenance Center (OMC)

5.6.1. Local Login The login via VT100 terminal or a PC with VT100 emulation can only be performed at the repeater. Open the repeater carefully and ensure that DIP-switch 2 of mode-switch [1] is in position OFF. Only when DIP-switch 2 is OFF, a local access to the software on the control module is possible (see chapter 5.5 DIP-Switches). Connect the terminal or PC to the RS232-interface on the control module by means of a standard RS232-null-modem cable. Check the communication mode at 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

Please type

<.> (fullstop) and confirm with <CR> (carriage return) to get to the login orders.

Note: Sometimes it is necessary to type the <.> (fullstop)-command two or three times to get access to the repeater software.

Note: All inputs are case sensitive, no blanks allowed. The connection will be torn down after three wrong inputs.

After successful login, the USERID is required. ----------------------------------------------------------------------------------------------------------------- ENTER USER ID: ----------------------------------------------------------------------------------------------------------------- Please enter

<UserID1>* and confirm with <CR> (carriage return). * UserID1 is factory-set and can be changed by software.

Now, the correct password is asked. The following order will be displayed on the terminal:

5 Commissioning

----------------------------------------------------------------------------------------------------------------- ENTER PASSWORD: ----------------------------------------------------------------------------------------------------------------- Please enter

<P-word1>** and confirm with <CR> (carriage return). ** P-word1 is factory-set and can be changed by software. If the software login procedure was successful, the input request shown below displays on the terminal: ----------------------------------------------------------------------------------------------------------------- ANDREW > ----------------------------------------------------------------------------------------------------------------- All parameters of the repeater can now be changed to optimize the repeater to the network system.

5.6.2. Remote Login A login e.g. via modem and the OMC enables the operator to set parameters and to query the status of each repeater. This can be done either via a wireless modem or a PSTN-modem. The access commands to the repeater software are the same as described in chapter 5.6.1 Local Login. If the OMC is used for the remote login, the input “<.> (fullstop) and <CR> (carriage return)” is skipped and UserID and Password are requested right away. For further details on software login and software commands, please refer to the software manual.

5.7. LEVELLING OF THE REPEATER After software login, the repeater must be levelled so the highest output power is achieved without reaching the ALC (Automatic Level Control).

Note: When the local software configuration is finished, do not forget to switch back DIP-switch 2 of the mode-switch 1 to position ON, otherwise the remote mode via modem will not work.

5.8. MR1934 OPERATION WITH MULTIPLE RF CHANNELS The manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction has to be achieved by reducing input power or reducing gain but not by an attenuator at the output of the device.


M0096A1C.doc

5.9. OPTIONAL MODEM MC35 OR MC46 To insert the SIM-card into the optional modem (MC35 or MC46), proceed as follows:

• Loosen the two headless screws at the inner side of the cabinet cover, which hold the locking guide pins of the modem box cover.

• Unscrew the four flat-head

screws with a Torx screw driver or Torx wrench and open the cover of the modem box.

• Open the SIM-card drawer of the MC35 by pressing the push button (e.g. with a

• Close the drawer by carefully pushing it in again.

• Close the cover of the modem box and adjust it with the four flat-head screws.

• Fasten the two headless screws at the inner side of the cabinet cover that hold the locking guide pins of the modem box cover.

6 Alarms

6. ALARMS

6.1. BITE AND ALARMS The Built-In Test concept comprises the monitoring of the power supplies, the motherboard and the remote control interface. Furthermore, the synthesizer lock and the temperature of the repeater are monitored. All alarms occurred 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 stability 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 acknowledges 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. SUMMARY ALARM RELAY

Pin 3 PinPin

The summary alarm relay is a potential-free relay. It is raised when one or more of the alarms is / are raised and is only re-set when all alarms are cleared. It can be used to monitor alarms with an external alarm indicator. Devices connected to this relay must not exceed a maximum switching power of 12 Vdc, 0.125 A. For the location of the connecting clamps of the summary alarm relay please refer to chapter 3.3.6 Connecting Board.

M0096A1C.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 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 available as a separate software manual.

8 Maintenance

8. MAINTENANCE

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

Note: The repeater does not require preventive maintenance measures. It is only recommended to replace the RTC battery and - if installed - the battery pack of the battery backup module after three years of usage as a preventive measure. The nominal lifetime of these batteries is five years under normal environmental conditions.

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 antenna systems as well as the continuity of the entire cabling including connectors before replacing any 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 the housing, the upper screws have to be removed first and then the lower screws. Proceed in reverse order to close the housing. Consequently, the spare parts list only contains units which can be replaced without tuning or soldering work. Those units are all parts from the supplier as well as internal and external cables.

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

Note: During maintenance ensure that the repeater has been disconnected from mains and that - if installed - the battery backup module has been switched off / unplugged.

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

Note: Before disconnecting any cables, label any unlabelled cables to ensure correct re-connection, and check the switch positions of the removed part to set the switches of the new part accordingly.

Note: Depending on the repeater configuration, some components are equipped with a 50-Ohm termination resistor. In such a case, use the termination resistor of the removed part to terminate the respective connector of the replacement part.


M0096A1C.doc

For most maintenance procedures appropriate tools are required to ensure correct handling. All these tools can be ordered from the supplier. For screwing procedures observe that all our screws have a right-hand thread, i.e. for fastening the screws turn the tool clockwise and for unscrewing them turn it anti-clockwise. For SMA connectors, a specified torque of 100 Ncm has to be observed. Therefore, use an appropriate tool. Also, specified torques have to be observed for screws, depending on 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. Screw type Tallow-drop Socket-head-cap Countersunk-head Thread size Specified torque (in Ncm) M 2.0 40 not in use 40 M 2.5 82 not in use 82 M 3.0 145 100 145 M 4.0 330 330 330 M 5.0 650 not in use 650
