USER´S MANUAL FOR BAND SELECTIVE REPEATERS MRX03P User'sManual.doc Id.-No.:154999 Page 11 22-Jan-01 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.
USER´S MANUAL FOR BAND SELECTIVE REPEATERS MRX03P User'sManual.doc Id.-No.:154999 Page 12 22-Jan-01 2.3. 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. Modem connect. (20dB) 30dB Coupler
USER´S MANUAL FOR BAND SELECTIVE REPEATERS MRX03P User'sManual.doc Id.-No.:154999 Page 13 22-Jan-01 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 MRX03P User'sManual.doc Id.-No.:154999 Page 15 22-Jan-01 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. figure 2-5 Control module

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: Modem Network Initstring Siemens M1* GSM900 ATE0S7=60S0=2\N6 Siemens M20* GSM900 ATZE0S0=2&S0+IFC=0,0+CBST=7,0,1 Motorola Mobile MR30 “Surf–Pro”** PCS1900 AT*P1&F&K4E0S0=2\N0+CBST=7,0,1 MIKOM MO4000 GSM900/1800 ATE0S7=60S0=2;+CBST=7,0,1 PCMCIA-modem PSTN AT&FE0S0=2 * The Siemens M1 modem is no longer available and is replaced by the Siemens M20. In future, it is assigned to replace all wireless modems working in GSM900/GSM1800 networks by the new MIKOM modem MO4000. **in connection with Cellect2 Card table 3-1 Standard initstrings for modems For further details to the initstrings, please refer to the user’s software manual.

USER´S MANUAL FOR BAND SELECTIVE REPEATERS MRX03P User'sManual.doc Id.-No.:154999 Page 21 22-Jan-01 3.2. 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 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.

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**: +30 dBm Received level of BCCH: -(-40) dBm ---------------- Allowed max. gain: 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 MRX03P User'sManual.doc Id.-No.:154999 Page 30 22-Jan-01 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 RF-repeaters, 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: 80 dB SGM: - 15 dB ------------- Allowed max. gain: 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 ICE-repeater. 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: 80 dB SGM with ICE-option: +5 dB higher ---------------------- Allowed max. gain: 85 dB For further details to ICE or antenna isolation, please refer to MIKOM “Application Note for Antenna Isolation” or “ICE Datasheet”.

MANUAL SETTINGS Normally, settings are carried out by a VT100 terminal or PC. Additionally, if manual settings are unavoidable, rotary switches on the motherboard enables the operator to optimize the gain and to set the channels. To enable the manual setting of attenuation and channels, ensure that the DIP-switch 1 of the mode switch [1] is in position ON (manual mode). An attenuation of 30 dB max. in steps of 2 dB can be set in the UL- and DL path for channel and band selective repeaters. The channel settings are only available for channel selective repeaters. ∗ Note: While DIP-switch 1 of mode switch (1) is in position ON (manual mode), software settings via VT100 terminal are not possible! Quering the status can still be carried out. figure 5-3 Motherboard Example: Position 0 of the rotary switches S7/S8 equals 0 dB attenuation. Position 1 attenuates the signal by 2 dB, position 8 for instance attenuates by 16 dB. To achieve max. attenuation (30dB), turn the rotary switch of the corresponding path to position F. S4 S5 S6 S7 S8 S9 S1 S2 S3

LEVELLING OF THE REPEATER After software-login, the repeater must be levelled so that the highest output power is achieved without reaching the ALC (Automatic Level Control). ∗ Note: When the local software configuration is finished, don´t forget to switch back DIP-switch 2 of the mode-switch to position ON, otherwise the remote mode via modem will not work!
USER´S MANUAL FOR BAND SELECTIVE REPEATERS MRX03P User'sManual.doc Id.-No.:154999 Page 39 22-Jan-01 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.

USER´S MANUAL FOR BAND SELECTIVE REPEATERS MRX03P User'sManual.doc Id.-No.:154999 Page 43 22-Jan-01 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.
