3) GENERAL DESCRIPTION Mobile phone systems have increasingly been spreading in these last years. Besides providing reliable and good quality connections, telecommunication system services should cover as widest territory as possible. It is well-known that connections to users’ terminals are obtained on air by means of steady stations named radio bases, located through the whole territory so as to obtain a continuous covering through cells one next to another.
Off-Air Repeaters on one side receive the signals from the radio base station, amplify them and re-transmit them in the direction of the shadow area (down-link path). On the other side Off-Air Repeaters receive the signals from the mobiles (MS), amplify them and re- transmit them to the base station (up-link path). When a single Off-Air Repeater does not provide satisfactory coverage, the repeater can be used along with other equipment.
• Tunnels with a length in the 300-meter to 600-meter range. Also in this case, one single Off-Air Repeater is sufficient. The repeater is located at the entrance to the tunnel and equipped with a leaky cable. This cable can be combined with a directional antenna to irradiate a portion of the area in front of the tunnel exit (Figure 4).
b) By an Off-Air Repeater connected to master unit and optical remote units with amplification steps of no more than 1200mt. each. The optical fiber system extends the signal through an antenna or a passive distribution system (Figure 6).

3.2) OPERATING PRINCIPLE – 1800/1900MHz ADJUSTABLE BANDWIDTH OFF-AIR REPEATERS The repeaters described in this handbook have been developed to permit cell coverage as set forth by the DCS (Digital Cellular System) standard for cell phones operating on the 1800MHz band or by the PCS (Personal Communications Service) standard for cell phones operating on the 1900MHz band. The DC powered repeater can be power-fed by a 48Vdc power supply source only.
The 48Vdc powered repeater is equipped with a DC/DC converter, ref. F. The A.C. powered repeater is equipped also with an AC/DC converter, ref. L. The management module, ref. G, makes it possible to manage the repeater in remote mode via a built-in modem, or in local mode through the RS232 connector, available on the management module. The repeater management is performed by means of the Operation and Maintenance Terminal software, both in local mode and in remote mode (ref. Chap. 4). 3.

4) INSTALLATION AND POWER-UP PROCEDURES Ref.: ILL DCS OFF-AIR REPEATERS / ILL PCS OFF-AIR REPEATERS WARNING: Before installing the equipment, carefully read the safety norms herewith attached. A correct repeater installation and setting procedure requires a good knowledge and experience in installing telecommunication equipment. These activities should be performed by skilled personnel only.
2. POSITIONING THE REPEATER The Off-Air Repeater is housed inside a case which provides high-degree environmental protection (IP65). Therefore it is suitable for outdoor wall mount installation. It can also be installed inside specific cabinets equipped with UPS units. Fix the Off-Air Repeater in vertical position on the wall, or on the vertical guides present inside the cabinet: • Lift the equipment and fix its position with four M8 bolts, which are to be inserted in the pre-cut slots (ref. A, FIGURE 2).
• D.C. POWERED EQUIPMENT - - Connect the 15-pole (f) connector on the bottom of the repeater (ref. 55, FIGURE 3) to the 48Vdc/Alarm cable (supplied with the equipment). The cable permits D.C power supply (48Vdc) to the equipment. It also makes available the remote signals detailed into Table 1. Connect the cable to the power supply source (48Vdc) and connect the external signals.
• AC POWERED EQUIPMENT (ALTERNATE CURRENT) - Connect the 230Vac power cable to the connector located on the bottom of the repeater (ref. 54, FIGURE 3). The connector pin assignments is detailed in Table 2. 230Vac POWER SUPPLY CONNECTOR PIN CABLE 230VAC POWER SUPPLY CABLE COLOR 1 2 3 4 LINE NEUTRAL GROUND (GND) NOT CONNECTED BROWN BLUE YELLOW / GREEN TABLE 2 – 230Vac POWER SUPPLY CONNECTOR PIN-OUT - Connect the other end of the cable to the power supply source (230Vac).
4.2) POWER-UP Warning: before power up, make sure that the isolation between the donor antenna and the service antenna is at least 15dB greater than the repeater gain. 1. 2. 3. Connect the cable from the donor antenna to a spectrum analyzer and check input signal presence and level. After measurement disconnect the spectrum analyzer. Switch on the equipment by means of the switches placed inside the repeater (FIGURE 1a and b).
4. 5. Check that the green LED on the 230Vac power supply module (when equipped) is ON (ref. 60, ILL DCS OFF-AIR REPEATERS, sheet 2). Check LEDs status on the 48Vdc power supply module: FIGURE 5 and Table 4 show LEDs status on the power supply module (DC/DC converter) under normal operating conditions. POWER SUPPLY 5V5 10V5 1A 2A FIGURE 5 – DC/DC CONVERTER: LEDS STATUS - CORRECT POWER UP REF. LED 1A LED 2A STATUS ON ON MEANING 5.5Vdc from DC/DC converter available 10.
6.WIRELESS MODEMS a. Models equipped with CDMA modem data communication between repeater (via built-in CDMA modem) and management workstation (PC where OMT/OMC management softwares have been previously installed) via PSTN and/or CDMA modem, must be established in CSD (CIRCUIT-SWITCHED DATA) mode only. All other modalities are not allowed. As CDMA modems don’t use SIMs, the network’s parameters have to be set manually by using the HyperTerminal.
The following procedure explains how to set the modem’s parameters. Please note: AT commands, contained between the inverted commas, must be strictly typed as it follows.
b. Models equipped with GSM modem How to install/remove the SIM card from the built-in modem • Open the repeater. • Check that the switches inside the repeater are set to 0 - OFF (FIGURE 1a and b). • Insert the SIM enabled to data transmission in not transparent mode 9600BPS (FIGURE 6) FIGURE 6 – DETAIL OF THE SIM INSERTION • Close the Management Module • Switch on the equipment (AC voltage circuit breaker, ref. 57, 48Vdc circuit breaker, ref. 22, FIGURE 1a-b). • Close the repeater. 7.
- The connector RS232 (ref. 58,FIGURE 7) and the connector RS232 (ref. 59, FIGURE 7) are connected with a cable (only in models equipped with CDMA modem). Switch on your notebook and start Windows. To Run the program select the related folder in the Windows ‘Start’ menu and click. The ‘Login panel’ is displayed (FIGURE 8). FIGURE 8 – LOGIN PANEL Select read/write user. PLEASE NOTE It’s not requested to insert the password the first opening of the program.
9. SET THE REPEATER GAIN, FREQUENCY CENTER AND BANDWIDTH - Select the menu entry ‘Read’ in the ‘Device’ menu, or click the ‘ equipment configuration and status. The software main window is displayed. By means of the software set the repeater gain as described below. Read’ button, to read the NOTE How to modify parameters: - Click on the ‘edit and save’ button, in the lower part of the window, to enable changes to the repeater parameters. - Click again on the ‘edit and save’ button to save changes.
PLEASE NOTE: should it be necessary to set an attenuation greater than 15dB it is strongly recommended to connect a fixed attenuator between donor antenna and the repeater BTS side port to avoid BTS desensitisation due to excessive radiated up-link noise. g) Check via the spectrum analyzer that the output signal level (MS side) is correct. When the output signal level is correct, disconnect the spectrum analyzer.
