If weak signal transmissions occur within the coverage area due to indoor applications, topological conditions or distance from the transmitter, a repeater is used to extend transmission range. In the downlink path, the repeater picks up the signal from a donor antenna of an existing cell, amplifies and re-transmits it into the required dark spot. In the uplink direction, the repeater receives signals from mobile stations present in its coverage area and re-transmits them to the corresponding base station. 1.1 The MR303D Varia The repeater MR303D Varia is a bi-directional amplifier with adjustable RFbandwidth. The first and the last channel of the transmission bandwidth can be set manually by means of rotary switches. The repeater has been designed for applications in medium sized rooms such as suites, offices and basements. A quality connection with a mobile phone can usually not be established in these rooms. The repeater is equipped with a connector for an external receiving/transmitting antenna which provides the RF connection to the mobile. Connection to the BTS can be established via an outdoor antenna. Other components of the D.I.C.E. COAX system can also be connected to the repeater. The final amplifiers are protected by individual level limiters, which allow the mobile unit to be operated in close proximity to the repeater. Third order intermodulation products are kept below the CEPT limit of -36 dBm constantly, even if the repeater receives the signals of more than one mobile unit. M0041A8B.doc Id.-No. 153114 Page 8 26-Oct-2000 User’s Manual for Repeater MR303D Varia 1.2 Functional Description The MR303D Varia is a repeater operating in the GSM900 frequency range. The operation principle for uplink and downlink is depicted in the following block diagram: figure 1-1 Block diagram 1.3 Downlink Downlink signals are received by the external antenna and fed to the duplexer. The duplexer is the frequency separation unit that splits and recombines uplink (UL) and downlink (DL). After processing through the duplexer the signals are transferred to a pre-amplifier and then enter the attenuation selection. The gain of the repeater can be set by introducing attenuation into the amplifier chain (see chapter 3.2 Setting the Attenuation). Then the signals are relayed to a mixer. The mixer converts the signals down to an intermediate frequency (IF). An IF filter provides the selectivity of the repeater. After the IF filter the signals are reconverted to the original frequency again with another mixer. A final amplifier amplifies the signal once again to the required output power. After amplification a power detection feature, called automatic level control (ALC), measures the output power and controls the gain. The ALC keeps intermodulations below - 36 dBm. Finally, the signals are supplied to the antenna output. M0041A8B.doc Id.-No. 153114 Page 9 26-Oct-2000 User’s Manual for Repeater MR303D Varia 1.4 Uplink The uplink signals are received by the antenna and fed into the repeater where a pre-selection of the frequency is made. The signals are then converted down to IF by means of a mixer and an IF filter provides the selectivity against other frequencies. After the re-conversion the signals are amplified in an amplifier that provides the output power. The signals are then fed to the antenna via the duplexer. In this link, an ALC and an automatic power adjust circuit (APAC) is provided. APAC limits the output power if two carriers are present at the one UL input. This again keeps intermodulations to the desired limit. The repeaters with Id.-Nos. 152797 & 154595 provide an attenuation selection unit, which allows the gain to be set on UL and DL -simultaneously, but not separately- by introducing attenuation into the amplifier chain. (See chapter 3.2 Setting the Attenuation). In the MR303D the bandwidth of the RF modules can be set within the GSM900 band to a desired value with rotary-switches on the outside of the modules. To set a defined bandwidth, the start channel, as well as the stop channel must be adjusted with the rotary-switches. (See chapter 3.1 Adjusting the Frequency).

These ports must be connected to the RF cables of the external antennas to/from the BTS and to/from the mobiles. M0041A8B.doc Id.-No. 153114 Page 11 26-Oct-2000 User’s Manual for Repeater MR303D Varia 2.1.2 Power supply The socket for the DC supply is located next to the RF connector to/from the BTS. Power supply voltage is 6.7 Vdc, current is 1.6 A typ for Id.-No.: 152796 and 2.5 A for Id.-Nos.: 152797 & 154595. There are two possibilities to provide the MR303D Varia with power: Ø Use external power supply and connection to the DC socket of the repeater. (Use only the power supply that is delivered with the unit). Or: Ø Bias the MR303D Varia via the cable to the RF port to/from BTS. Ensure that the correct voltage is fed into the repeater. Note: The DC socket of the MR303D Varia must not be connected if the bias via RF cable is carried out. 2.2 Configuration of the LEDs The LED to the left (DC alarm) can show green or red light: Ø Green indicates the normal operation of the repeater. Power is present and the current consumption of the unit is within the specifications. Ø Red indicates that the current consumption of the repeater is not within defined limits and that the repeater might not work properly. If the LED is off, the MR303D Varia does not receive any DC power. The right hand LED is the ALC/APAC alarm LED: Ø LED “on” indicates that the input power received by the repeater is too high. The output power of the repeater must be limited. This can be either done by the UL ALC or APAC, or the DL ALC. Limitation of power ensures that the final stage is not overdriven and that intermodulations are kept below the CEPT limits (- 36 dBm).

The unit can be mounted horizontally or vertically. The alarm LEDs must point downwards (horizontal mounting) or to the left-hand side (vertical mounting). The unit has a weight of approximately 1.6 kg. figure 2-2 Installation drawing M0041A8B.doc Id.-No. 153114 Page 13 26-Oct-2000 User’s Manual for Repeater MR303D Varia 2.4 Electrical Installation F Note: Electrical installation must be carried out in accordance with the safety regulations of the local authorities. Due to safety reasons electrical installation must be performed by qualified personnel only. Connection of the cables to/from the BTS and connection of power supply: The cable to the external antenna to/from the BTS and the SMA-connector must be ordered separately if reqired. If the cable is part of the delivery, adjust the cable to a suitable length and connect the SMA-connector. Cut the antenna cable to the required length. Strip the jacket at the cut end to the length of 14 mm, the copper braiding carefully to 8 mm and the inner insulation to 10 mm. Place the split taper socket over the cable. Insert the inner conductor into the opening at the rear of the SMA pin. Slot the pin and cable into the opening at the rear of the SMA connector. Carefully push the copper braiding over the knurled end of the connector. Take care that none of the wires of the copper braiding contact the inner conductor. Pull the split taper socket over the cable up to the base of the SMAconnector. Complete the connection by crimping the split taper socket with crimping pliers.
