1. FIXED BAND OFF-AIR REPEATERS - OR2-SBLP1 SERIES
Over the past decade, the growing diffusion of portable terminals has created the need for capillary coverage
of the territory. Telecommunications networks must permit coverage services throughout the territory in the
most extensive manner possible and, at the same time, guarantee the reliability and quality of the connection.
From this point of view, the availability and quality of the services must be also guaranteed indoors, i.e. inside
buildings.
OR2-SBLP1 SERIES has been designed specifically to improve cell coverage to indoor environments (indoor
applications): offices, stores, parking lots, malls, airports and train stations.
Each equipment in OR2-SBLP1 series is dedicated to a mobile standard (please refer to TABLE 1).

2. OPERATING MODE
Off-Air Repeaters for indoor applications are connected, by means of coaxial cables, to two antennas. The
‘donor antenna’, an outdoor one, interfaces the equipment with the Mobile Operator’s Base Transceiver
Station (BTS). The ‘service antenna’, an indoor one, empowers the coverage of the indoor dead spot, and so it
interfaces mobile terminals.
The signal to be enhanced follows two distinct paths (FIGURE 1). The up-link path, from mobile terminals to
the BTS, and the down-link path, from the BTS to mobile terminals.
Along the down-link path, the outdoor antenna receives the signal from the BTS and then, by means of the
connecting cable, delivers it to the repeater BTS connector (ILL OR2-SBLP1 SERIES, ref. 4). The repeater
filters, amplifies and transmits the signal by feeder cable to the indoor antenna “filling” the indoor dead spot.
Indoor antenna is connected to the repeater MS connector (ref. 7, ILL OR2-SBLP1 SERIES).
Along the up-link path, the indoor antenna receives the signal from the mobile terminals (MS) and delivers it to
the repeater. The repeater filters, amplifies and transmits the signal by the outdoor antenna to Operator’s BTS.
FIGURE 1 – DOWN-LINK and UP-LINK PATHS
OR2-SBLP1 series repeaters have got built-in attenuators to allow adjustable gain. DIP-switches (ref. 5 and
ref. 6, ILL OR2-SBLP1 SERIES) are available to adjust the gain separately for up-link and down-link paths.
During installation, equipment gain can be adjusted to reduce interference towards the BTS and to avoid
problems related with the isolation between the antennas.
During operation, the equipment Automatic Level Control (ALC) protects against the emission of high
intermodulation products, both in case that the user is in the nearby vicinity of the indoor antenna (ALC uplink) and in case of a temporary level increase of the signal coming from the donor antenna (ALC down-link).

4. PROCEDURES FOR INSTALLATION AND POWER-UP
• Before installing, carefully read the safety norms herewith attached.
• The equipment must be connected to ancillaries specifically designed for the standard in use
and the band to be enhanced.
• The OR2-SBLP1 SERIES has been designed for indoor use only. Changes in temperature
and humidity can influence the reliability of the equipment. The best place to install the
equipment is a tempered and well-ventilated environment.
• A correct equipment installation and setting procedure requires a good knowledge and
experience in installing telecommunication equipment. These activities should be performed
by skilled personnel only. Remember that if the equipment is not installed correctly, it may:
- cause a temporary failure in the BTS,
- be damaged by excessively high input or output signal levels.
To install the equipment we strongly suggest to follow the steps described in the paragraph below.
4.1. PLANNING INSTALLATION
• Selecting the position for the outdoor antenna
The power of the signal coming from the outdoor antenna (donor antenna) has a direct influence on the
efficiency of the indoor coverage. Therefore, it is extremely important to take care in choosing the position
for this antenna and in installing it correctly.
Before installing the outdoor antenna, it is necessary to point the donor BTS to guarantee the best
reception of signal to be enhanced. The best way to perform this activity is by connecting the donor
antenna to a spectrum analyzer (or to a field intensity level measurement instrument) to evaluate the
orientation and position of the antenna which can provide the best signal level.
It is strongly recommended to keep both antennas away from obstacles such as mountains, tall buildings
or billboards.
It is furthermore recommended to use a directional outdoor antenna with, at least, 10dBi gain and to
make sure, insofar as possible, that the antenna is pointing directly towards the BTS.
Please Note:
To obtain the best equipment performances, the outdoor signal must be stronger than -70dBm
and must not go above -20dBm. If the outdoor signal is weaker than -70dBm, it is strongly
recommended to use a high-gain directional outdoor antenna.
The ideal outdoor signal level is in the -60 to -70dBm range.

FIXED BAND OFF-AIR REPEATERS

ENG Edit. 02
• Isolation between the antennas
Since the equipment is a bi-directional amplifier, the isolation between the outdoor antenna (donor) and
the indoor antenna (service) must be at least 15dB greater that the repeater gain. For example, if the
repeater gain is 60dB, the minimum isolation between both antennas must be greater than 75dB.
To guarantee the correct isolation between the antennas, it is necessary to plan for an adequate distance
between them, both horizontally and vertically. Also walls and floors can be useful to increase the
isolation between the antennas.
• Repeater gain setting
During installation, it is necessary to adjust the equipment gain. The right calculation of the gain to be set
cannot be made without an evaluation of all the variables which characterize each installation.
The minimum gain value to be set on the up-link / down-link path is determined by considering the
maximum output power and the maximum allowed input level of the equipment (-20dBm).
The balance between losses and gains for the equipment (link budget) permits adjusting the attenuation
of the two paths (down-link / up-link), in order to reduce interferences towards the BTS and to avoid
problems connected with the isolation between the antennas. Link budget also permits checking whether
or not the output signals from the equipment (towards the BTS and towards the mobile terminals) are
adequate.
PLEASE NOTE:
The repeater has been developed to operate at maximum gain. If attenuated, maximum
output power will be reduced proportionally. ALC is always enabled.
It is strongly recommended to set the repeater gain at maximum level. Attenuation should
be set only if antenna isolation is not enough (less than 75dB).

4.2. MECHANICAL AND ELECTRICAL INSTALLATION OF THE REPEATER
Upon completion of the planning stage, you can proceed with the installation of the antennas (indoor and
outdoor) and then with the installation and power-up of the repeater.
Please remember: the OR2-SBLP1 SERIES is designed for indoor use ONLY.
• Initial check
Check the contents of the supply in terms on its completeness and/or eventual damage undergone by the
material during transport.
The materials included in the supply are:
• OR2-SBLP1 SERIES equipment,
• External AC/DC adapter,
• Technical manual.
If there should be anything missing or damaged in the supply, you should notify the Sales Dept. of RFS, to
facilitate the reinstatement and/or repair of the equipment involved.
Before beginning installation of the equipment, make sure that ON/OFF switch, ref. 3 (ILL OR2SBLP1 SERIES), is in the OFF position. The green LED, ref. 2 (ILL OR2-SBLP1 SERIES), must
be turned off.
• Positioning
To avoid damages to people, it is highly recommended to install the equipment at 2.5metres high
positioning, in order to prevent electric shock caused by contact.
Position the OR2-SBLP1 SERIES equipment and fix its position with the four M4 bolts, which are to be
inserted in the pre-cut slots, ref. A (FIGURE 2).
Check the correct positioning of the equipment before completely tightening the bolts.

• Connections
A) Connect the cable from the outdoor antenna to connector N (f) BTS side, ref. 4 (ILL OR2-SBLP1
SERIES).
B) Connect the cable from the indoor antenna to connector N (f) MS side, ref. 7 (ILL OR2-SBLP1 SERIES).
C) Connect the power supply connector for the external AC/DC adapter (standard supply) to the power
supply socket connector of the equipment, ref. 1 (ILL OR2-SBLP1 SERIES).
D) Connect the power supply plug of the external AC/DC adapter (standard supply) to the line power source
corresponding to the specs of the equipment (i.e. 100-230V A.C.).
For the connections, it is recommended that an RF cable having characteristics similar to the RFS cable type
LCF14-50, be used.
• How to set the repeater gain
PLEASE REMEMBER:
It is strongly recommended to set the repeater gain at maximum level. Attenuation should
be set only if antenna isolation is not enough (less than 75dB).
The OR2-SBLP1 SERIES equipment comes with selectors which permit separately adjusting the gain for both
up-link and down-link paths. The maximum gain for the equipment is 60dB (typical). The attenuation of the
gain can be adjusted in the 0÷30dB range with steps of 1dB.
The variations to be made to the gain on the up-link and down-link paths are determined during link budget
calculation stage (ref. paragraph 4.1).
Please set the gain as shown in FIGURE 3 (Example of gain adjustment).

ENG
1.4 Caution and warning statements
Caution It's used to indicate the correct operation and maintenance, in order to prevent damage or
destruction of equipment or other property. Warning of danger Used to indicate the potential hazard that
requires correct procedures or practices in order to avoid personal injury.
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 semiconductor 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 below:

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.
