1) SAFETY RULES
1.1 Introduction
The equipment described in this technical handbook has been designed and tested in conformity of
international safety standards IEC215 / EN60215 and IEC950 / EN60950; the equipment has to be used
under the responsibility of specialised personnel only. In accordance with IEC215 / EN60215, adjustment,
maintenance and repair of the exposed equipment shall be carried out only by qualified personnel, who are
aware of the hazards involved. The minimum qualifications are established in the standard.
Final installation of the systems must fulfil the EMF emission levels, as requested by regulations in force
(recommendation n. 1999/519/EC).
WARNING: Installation Notes
Modular equipment, intended to be housed insidea rack cabinet, must be installed within a protected
access area only.
This area must be opportunely protected by security system that will exclude the entry, even if accidental, to
not authorized and trained personnel. Alternatively, the cabinet, in which the equipment is housed, must be
closed on all sides, to allow the access to internal parts to authorized personnel only
1.2 AC Power supply
When working on the equipment always make sure that the equipment is not connected to the mains
supply.
Before power up always make sure that the equipment is connected to earth by using the equipment
grounding bolt.
If it is necessary to fit an AC power supply plug to power cable, the User must observe the following colour
codes: LIVE terminal to BROWN lead NEUTRAL terminal to BLUE lead EARTH terminal to GREEN/YELLOW
lead The User must also ensure that the protective earth wire would be the last to break, should the cable be
subject to excessive strain.
1.3 Safety precautions
For the correct and safe use of the equipment it is essential that both operation personnel and services
personnel follow generally accepted safety procedures (see IEC Publications 215: "Safety measures for
radio transmitting equipment" and 61010-1: "Safety requirements for electrical equipment for measureme nt,
control, and laboratory use") in addition to the safety precautions specified in this technical handbook.
Specific warnings and caution statements, where applicable, can be found throu ghout this technical
handbook. Warning and caution statements and/or symbols are ma rked on the equipment where is
necessary. (see also ANNEX n°1).
As far as the equipment safety devices are concerned please remind that: -periodic functional check shall be
carried out on protective devices; -functional check shall be carried out on protective devices, when they
have operated under fault conditions; -safety devices shall not be altered or disconnected except for
replacement; -safety circuit shall not be modified.

1.4 Caution and warning statements
Caution
destruction of equipment or other property. Warning of danger
requires correct procedures or practices in order to avoid personal injury.
It's used to indicate the correct operation and maintenance, in order to prevent damage or
Used to indicate the potential hazard that
1.5 Impaired safety protection
Whenever it is likely that safe operation is impaired, the apparatus must be in-operative and secured against
unintended operation. The appropriate servicing staff authority must be informed.
For instance, the safety is likely to be impaired if the equipment fails to perform the prescribed
measurements, or shows visible damages.
1.6 Electrostatic sensitive devices
In case of electrostatic sensitive devices ( for instance all ICs and many other semicondu ctor devices belong
to this class) it is essential to use a right protection to reduce the risk of personal injury. Careless handling,
during repair, may imply life danger. When repairing, make sure that you are connected with the same
potential as the ground of the equipment by means of the right devices, i.e. a GIRDLE (a wrist wrap with
resistance) and a WINDING CORD to be connected to the girdle and to the relevant socket placed on the
equipment.
You must also keep components and tools at this potential.
1.7 Electrolytic Capacitors
Non-solid electrolytic capacitors must not contain chemicals, which may be regarded as hazardous, if
incorrectly handled. Caution is necessary, should the outer case be fractured.
1.8 Electric shock
In case of electric shock it is recommended not to touch the person before breaking the circuit by means of
the power supply switch; should it be not possible to break the circuit power supply it would be advisable to
try to rescue the person by means of some insulating materials: e.g. a wood stick, a nylon cord or a suitable
service made of plastics, etc.
NEVER TOUCH ELECTROCUTED PEOPLE WITH YOUR HAND AS LONG AS THEIR BODIES ARE
SUBJECTED TO VOLTAGE, OTHERWISE YOU TOO WOULD GET ELECTOCUTED.
Call the doctor and then immediately perform the artificial respiration as described here belo w:
SAFETI RULES ENG
Lay the patient on his back with his arms parallel to his body; if the patient lies on an
inclined plane, please make sure that his stomach be slightly lower than his breast.
Open the patient's mouth and check if there are foreign bodies. Kneel down near the
patient at the same level as his head's, put one of your hands under his head and the
other one under his neck. Lift the patient's neck and let his head fall backwards the
most possible.
Shift your hand from the patient's neck to his chin; put your thumb between his chin
and his mouth, your forefinger along his jawbone, keep your other fingers tight. By
doing these operations start the self-oxygenation by means of deep breathings in
standing open-mouthed. With your thumb between the patient's chin and his mouth,
keep the patient's lips closed and blow into his nasal cavities.
During these operations see if the patient's breast rises. If it is not so, his nose may be
obstructed; in this case, by levering on his chin with your hand, open the patient's
mouth, put your lips on and blow into his oral cavity. Look at the patient's breast and
see if it rises. One can use this second method instead of the first one also if the
patient's nose is not obstructed, provided that his nose be occluded by squeezing his
nostrils with your hand after shifting it from his head. The patient's head must be kept
bent backwards the most possible.
Start with ten fast and deep expirations, then go on at the rhythm of twelve/fifteen expirations per minute.
Continue as long as the patient has recovered consciousness, or a doctor has ascertained his death.
1.9 Burns
As far as burns are concerned: Don't try to take off clothes from the burnt
parts; Pour some cold water on body burnt areas and ask immediately for a
doctor; Don't apply ointments or oily tinctures.

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.
That allows a great number of users to enter the system using few channels.
It is important to maintain the continuity of radio-electrical coverage (and consequently, of service within
each cell) in order to guarantee an acceptable level of communication.
BTS Tri-cellular
FIGURE 1 – SUBDIVISION OF THE TERRITORY IN CELLS
Off-Air Repeaters are proposed as a valid and economical solution to optimize the cell coverage of the
territory and irradiate shadow area as an alternative to solutions requiring dedicated Radio-Bases (Figure 2).

CHAPTER 3
3.1
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. Different solutions are provided: cascade systems, based on Bi-Directional Amplifiers, and
optical fibre solutions, based on Remote Units.
3.1) EXAMPLE: USE IN TUNNELS
The Off-Air Repeater interfaces directly with the BTS of the provider of the services to be extended, and can
be used along with other equipment distributed inside the tunnels. Such equipment can be divided into two
types, according to the radio-coverage system used:
- Bi-directional amplifiers, for cascade systems.
- Remote Units, for optical systems.
The following are a few examples of general projects for radio-elec tric coverage in tunnels.
• Tunnels with a length of less than 300 meters.
In this case, one single Off-Air Repeater is sufficient. It is located at the entrance to the tunnel, equipped
with an antenna which irradiates in the direction of the shadow zone (Figure 3).

• 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).

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 AC powered repeater can be
power-fed from MAINS (230Vac) or from a 48Vdc power supply source or both from MAINS and from a
48Vdc source. The presence of both power supply voltages guarantees the continuity of the coverage
service even in case of failure of one source. The commutation is handled automatically by the repeater.
Off-Air Repeaters are bi-directional amplifiers. The signal to be extended follows two distinct paths: the uplink path, from the mobiles to the radio base station, and the down-link path, from the radio base station
towards the mobiles.
Figure 7 provides a block-diagram of the 1800/1900MHz adjustable band Off-Air Repeater.

In down-link the RF signal from the donor antenna is filtered and pre-amplified by a low-noise amplifier (LNA,
ref. C1).
The selection of the band of frequencies to be extended is handled by two band-selective modules, ref. D1
and ref. D2, which make the band-pass and frequency center programmable entities.
The band of frequencies to be extended can be managed by the user by means of the management system.
The signal is then amplified by the High power amplifier (ref. E1) filtered by the MS side duplexer, ref.
B2,and transmitted by an antenna or a passive distribution system.
A VSWR detector is equipped.
The up-link path is identical to the down-link path described above.

CHAPTER 3
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).

a. Models equipped with CDMA modem
data communication between repeater (via built-in CDMA modem) and management workstation
(PC where OMT/OMC management softw ares 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. Please contact your local Operator, communicating modem’s ESN (check the sticker at the
top of the management module), to get the needed parameters. Most common parameters are:

- Select the menu entry ‘Read’ in the ‘Device’ menu, or click the ‘
Read’ button, to read the
equipment configuration and status.
The software main window is displayed.
By means of the software set the repeater gain as described below.
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.
- The menu entry ‘Write’, in the ‘Device’ menu, makes it possible to apply changes to the repeater. A
password is required: default password is blank. To change the password please refer to the

a) In the tree structure of the repeater system (FIGURE 9) select the repeater (double click on
‘Repeater’): on the right side of the window, the configuration and status panels of the repeater
will be shown (Description, Spectrum, Parameters, Alarms, Communications, Advanced).
b) In the description panel, the user should select ( FIGURE
10) if the system is TDMA or CDMA.
This selection allows to load the right values of RF power transmitted by the HPAs (only for
1900MHz repeaters)
.
FIGURE 10 – Selection TDMA / CDMA
c) In the ‘Spectrum’ panel (FIGURE 11)set both ‘UL-attenuation’ and ‘DL-attenuation’ to 30 (dB) -
maximum attenuation, i.e. minimum gain.
d) Connect the cable from the donor antenna to the BTS connector on the bottom of the repeater
(ref. 52, FIGURE 3).
e) Connect the MS connector on the bottom of the repeater (ref. 56, FIGURE 3) to a spectrum
analyzer.
f) In the Spectrum panel, set the Up-link frequency center and bandwidth.
In the same panel set the repeater gain (UL-Up-link- attenuation, DL-Down-link- attenuation).

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.
FIGURE 11 – ‘SPECTRUM’ PANEL
If the repeater is used in stand-alone configuration, connect the cable from the service antenna to
the MS connector on the bottom of the repeater (ref. 56, FIGURE 3).
If the repeater is the head station of an optical fiber system, refer to the OPTICAL FIBER COVERAGE
SOLUTIONS technical handbook to install and set Master Unit and Remote Units.
If the repeater is part of a cascade system, refer to the IN-LINE AMPLIFIERS technical handbook to
install and set in-line amplifiers.
During operation the equipment can be managed, both in LOCAL and in REMOTE mode, via the software.
In REMOTE mode the equipment is managed via a modem link. On the repeater side the modem is
installed within the equipment management module.
If installing /removing the SIM card from the built-in modem is necessary, please refer to the following
procedure 6b (HOW TO INSTALL/REMOVE THE SIM CARD FROM THE BUILT-IN MODEM).
For details regarding the software, please refer to the software User’s manual.
