1. Safety
Any personnel involved in installation, operation or service of Allgon
repeaters must understand and obey the following:
•Allgon repeaters are designed to receive and amplify signals from one or
more base stations and retransmit the signals to one or more mobile
stations. Also, the repeaters are designed to receive signals from one or
more mobile stations, amplify and retransmit to the base stations. The
repeaters must be used exclusively for these purposes and nothing else.
•Repeaters supplied from the mains must be connected to grounded
outlets and in conformity with any local regulations.
•The power supply unit in repeaters supplied from the mains contains
dangerous voltage that can cause electric shock. Disconnect the mains
prior to any work in such a repeater. Any local regulations are to be
followed when servicing repeaters.
Authorized service personnel only are allowed to service repeaters while
the mains is connected.
•The repeater cover must be secured in opened position, e.g. by tying it
up, at outdoor repeater work. Otherwise, the cover can be closed by the
wind and cause your fingers getting pinched or your head being hit.
•When working on a repeater on high ground, e.g. on a mast or pole, be
careful not to drop parts or the entire repeater. Falling parts can cause
serious personal injury.
•Any repeater, including this repeater, will generate radio signals and
thereby give rise to electromagnetic fields that may be hazardous to the
health of any person who is extensively exposed to the signals at the
immediate proximity of the repeater and the repeater antennas.
BERYLLIUM OXIDE
•The CHA channel board power transistors, the PA amplifier board
power transistors, and the combiners (CMB) contain beryllium oxide
(BeO) that is poisonous if present as dust or smoke which can be
inhaled. The power transistors mentioned are mounted with two
screws as opposed to other transistors.
Do not file, grind, machine, or treat these parts with acid.
Warning signs are applied on boards and units that contain beryllium
oxide. These warning signs are shown in the next section.
HYDROGEN FLUORIDE
•The coaxial cable insulation is made of PTFE, polytetrafluoro ethylene,
that gives off small amounts of hydrogen fluoride when heated.
Hydrogen fluoride is poisonous. Do not use heating tools when
stripping off coaxial cable insulation.
No particular measures are to be taken in case of fire because the
emitted concentration of hydrogen fluoride is very low.
Allgon Systems AB AR Repeaters Safety
VD203 66/EN - User’s Manual Rev. P1A 2000-09 1 - 1

•A lithium battery is permanently mounted on the CU board. Due to
the risk of explosion, this battery must not be removed from the board.
In case of battery malfunction, replace the CU board. The old CU
board can be sent to Allgon for repair.
•The heat sink element on the CDMA High Power repeater can be very
hot. Do not touch this surface during operation.
Warning Signs
The following warning signs must be observed and be kept clean and
readable.
Beryllium oxide
This warning sign is applied on boards and units which contain beryllium
oxide parts.
This warning sign is applied at the bottom, inside the cabinet, below the
power supply unit.
The previous section details parts containing beryllium oxide and how to
avoid dangerous dealing with these parts.
Static Electricity
Static electricity means no risk of personal injury but it can severely
damage essential parts of the repeater, if not handled carefully.
Parts on the printed circuit boards as well as other parts in the repeater
are sensitive to electrostatic discharge.
Never touch the printed circuit boards or uninsulated conductor
surfaces unless absolutely necessary.
If you must handle the printed circuit boards or uninsulated conductor
surfaces, use ESD protective equipment, or first touch the repeater
chassis with your hand and then do not move your feet on the floor.
Never let your clothes touch printed circuit boards or uninsulated
conductor surfaces.
Always store printed circuit boards in ESD-safe bags.

2. Introduction
Allgon repeaters are used to fill out uncovered areas in cellular mobile
systems, such as base station fringe areas, road tunnels, business and
industrial buildings, etc.
A repeater receives signals from a base station, amplifies and retransmits
the signals to mobile stations. Also it receives, amplifies and retransmits
signals in the opposite direction. Both directions are served
simultaneously.
To be able to receive and transmit signals in both directions, the repeater
is connected to a donor antenna directed towards the base station and to
a service antenna directed towards the area to be covered.
Control of the repeaters is performed using a desktop or notebook loaded
with the Allgon OMT32, Operation and Maintenance Terminal, which can
communicate with the repeaters, either locally or remotely via modem.
Remote operation can be performed either via a traditional telephone line
or via a mobile phone that can be installed inside the repeater.
To be able to control many Allgon AR repeaters in common, there is an
Allgon OMS, Operation and Maintenance System.
The repeaters and the OMT32 is described in this manual. The OMS is
described in the OMT32, User’s Manual.

Repeater Types
The following repeater types are currently available:
•Channel selective GSM repeater
•Channel selective CDMA repeater
•Channel selective high power CDMA repeater
•Band selective repeater with fixed bandwidth
•Band selective repeater with adjustable bandwidth
•Combined repeater
In the OMT32, the channel selective 900, 1800, and 1900 systems are
called GSM, DCS and PCS respectively, even though these systems may
have different names in other parts of the world.
Channel selective GSM repeater
A channel selective GSM repeater can be equipped with two, four, six or
eight channels. This repeater type is used for channel selective systems,
such as GSM, DCS, PCN and GSM 1900 (PCS).
Channel selective CDMA repeater
A channel selective CDMA repeater can be equipped with one or two
channels. This repeater type is used for digital code division systems in
accordance with IS-95 or J-std-008 standard.
Channel selective high power CDMA repeater
A channel selective CDMA repeater like the previous one, but equipped
with a 6dB (typically) BA (Booster Amplifier) unit.
Band selective repeater with fixed bandwidth
A band selective repeater with fixed bandwidth has fixed filters for a
certain bandwidth. This repeater type is used for analog or digital
systems, such as NMT, GSM, TACS, ETACS, AMPS, DAMPS and CDMA.
Band selective repeater with adjustable bandwidth
A band selective repeater with adjustable bandwidth has filters that can
be set to various bandwidths. This repeater type is used for analog or
digital systems, such as NMT, TACS, ETACS, AMPS, DAMPS and CDMA.
Combined repeater
Some of the above mentioned types can be combined in the same repeater
chassis and be in operation in parallel.

Using Repeaters
In areas where the radio signal propagation is poor repeaters can be used
to fill out those areas which are not covered by the base station.
The following scenarios are examples on this:
–Sports arenas
–Fair halls
–Large shopping centres
–Road and railway tunnels
–Indoors in buildings with metal or concrete walls
Other examples where repeaters can be used to increase the coverage are:
–Shaded areas
–Fringe coverage areas
In areas where the traffic intensity is low, it is not cost efficient to install
a base station. An Allgon repeater, which can be installed with a
minimum of investments, is a much better solution. You save installation
costs as well as operational costs.
Examples of using repeaters
Two examples are described in the following sections. An outdoor example
in a shaded valley and an indoor example in a sports arena.
Allgon Systems AB AR Repeaters Introduction
User’s Manual VD203 66/EN Rev. P1A 2000-09 2 - 3

Shaded Area
A valley is shaded by hills. There is a base station 5 kilometers away, but
the lowest signal strength in the valley is less than –100dBm. A mast
used for other purposes is available for a repeater installation. The mast
height is 42 meter and it is located on a hill. The scenario is illustrated
in Figure 2-2.
The donor antenna of the repeater was mounted at the top of the mast
and the service antenna was mounted at the half mast. The antenna
isolation was measured to over 100dB. The repeater was set to 80dB gain.
Measured levels: Received signal level – 60.0 dBm
Donor antenna gain 15.0 dBi
Cable loss –5.0 dB
Repeater input level – 50.0 dBm
Adjusted repeater gain 70.0 dB
Repeater output level 20.0 dBm
Cable loss – 5.0 dB
Service antenna gain 8.0 dBi
Radiated output level 23.0 dBm
The measured result in the valley was better than –90dBm.

Sports Arena
A 2000 spectators sports arena with metallic roof had an indoor signal
strength too low to provide a fair service in most parts of the arena. The
nearest base station was 8 kilometers away and it was equipped with one
carrier only.
A donor antenna directed towards the base station was mounted on a
mast outside the building and a repeater was installed inside the building
with the service antenna on the arch vault. The scenario is illustrated in
Figure 2-3.
The antenna isolation was measured to over 85dB.
Measured levels: Received signal level – 80.0 dBm
Donor antenna gain 15.0 dBi
Cable loss –5.0 dB
Repeater input level – 70.0 dBm
Adjusted repeater gain 75.0 dB
Repeater output level 5.0 dBm
Cable loss – 2.0 dB
Service antenna gain 7.0 dBi
Radiated output level 10.0 dBm
The signal strength was fair for service in the entire arena.

3. Installation
Before installation, read carefully Chapter 1, Safety.
Siting the Repeater
Allgon repeaters are designed for outdoor usage. However, humidity and
temperature changes may have affect on the reliability. A preferable site
for the repeater is thus indoor, in a tempered and ventilated room.
Sunshine
If a repeater is placed outdoor and can be exposed to direct sunshine, it is
essential that the air can circulate around the repeater with no obstacle.
The operating temperature must not exceed +55°C. A shelter can be used
to shade the repeater from direct sunshine.
Shelter
Allgon repeaters are designed with a weather proof outdoor case that can
be mounted without any kind of shelter from rain, snow or hail.
If a repeater is to be opened on the site when raining, snowing, or hailing
there must be some kind of permanent or temporary shelter. This is
applicable to gentle rainfall, snowfall or hail. Limitations for very bad
weather is found in the next section.
Allgon can provide a shelter designed for these repeaters. This shelter is
shown in Figure 3-1.
Outdoor Installation and Service Limitations
Sited outdoors, the repeater must not be opened for installation or
service at bad weather, such as:
–Intense rainfall, snowfall or hail
–Storm or high wind
–Extremely low or high temperature
–High humidity of the air
