USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P 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.
USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P 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. 30dB Coupler Modem connect. (20dB) figure 2-2 Duplexer 2.3.2.
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.
USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P 2.3.4. Final Amplifier The UL- and DL path are amplified by a final amplifier. It is located next to the conversion module. figure 2-4 Final amplifier User'sManual.doc Id.-No.
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.
USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P 2.3.6. Motherboard The function of the mother board is the communication between the conversion module and the control module via the I2C-Bus.

USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P 4. INSTALLATION 4.1. MECHANICAL INSTALLATION 4.1.1. General F 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.
USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P 4.2. WALL MOUNTING PROCEDURE Check the suitability of the wall mounting kit and the wall. ∫ Dismount the mounting brackets which are screwed to the housing with four socket head cap screws M8x16 and two tire bolts. ∫ Use the wall mounting template to mark the position of the drilling holes. Drill four holes and screw the mounting brackets to the wall. ∫ Attach the upper two socket head cap screws M8x16 to the repeater housing.
USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P 4.2.1. Pole Mounting Procedure Standard mounting hardware can not be used to mount the repeater to a pole, a mast or other similar structures.

The bending radius of the antenna cables must remain within its specification G0847Z2 figure 4-4 Top view of antenna connections User'sManual.doc Id.-No.
USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P 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.
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.
USER ´S MANUAL FOR BAND SELECTIVE REPEATERS MRX 03P 5.2. BOOT PROCESS As soon as 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 twocoloured LEDs.
