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 contains dangerous voltage that can cause
electric shock. Disconnect the mains prior to any work in the 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.
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.
•A lithium battery is permanently mounted on the repeater board. Due
to the risk of explosion, this battery must only be removed from the
board by an authorized service technician.
ALLGON Systems AB ALR Compact Repeater Safety
VD203 67/EN - User’s Manual Rev. P1D 2000-05 1 - 1
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 board as well as other parts in the repeater
are sensitive to electrostatic discharge.
Never touch the printed circuit board or uninsulated conductor
surfaces unless absolutely necessary.
If you must handle the printed circuit board 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 compact repeater is described in this manual. OMT32 is described in
the AR Repeaters and OMT32, User’s Manual. OMS is described in the
Advanced Repeater OMS, User’s Manual.

Repeater Types
The following repeater types are available:
•Band selective repeater with adjustable bandwidth
•Combined repeater
Band selective repeater with adjustable bandwidth
The band selective compact repeater 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
Two separate band selective repeater units for different bandwidths or
systems 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 ALR Compact Repeater Introduction
VD203 67/EN - User’s Manual Rev. P1D 2000-05 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 max.
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 70.0 dB
Repeater output level 0.0 dBm
Cable loss – 2.0 dB
Service antenna gain 7.0 dBi
Radiated output level 5.0 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.
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

5. Functional Description and Design
Allgon repeaters work as bi-directional on-frequency amplifiers.
A repeater receives, amplifies, and retransmits signals downlink and
uplink simultaneously, i.e. from the base station via the repeater to the
mobile stations and from the mobile stations via the repeater to the base
station.
The repeater is connected to a BS antenna, directed towards the base
station, and to a MS antenna directed towards the area to be covered.
These antennas are connected to the repeater with N type male
connectors.
To prevent instability due to poor antenna isolation, a built-in antenna
isolation supervision feature reduces the gain level automatically when
poor antenna isolation is detected.
The Allgon repeaters are controlled by powerful microprocessors.
Alarm and operational LEDs are visible on the repeater front.
The repeater works with convection cooling without fan.
Operational parameters such as gain, power levels, etc. are set using a
desktop or notebook and the Allgon OMT32, which communicate, locally
or remotely via modem, with the repeater. Remote operation is
performed using a telephone line or a built-in mobile phone equipped with
a data interface.
ALLGON Systems AB ALR Compact Repeater Functional Description
VD203 67/EN - User’s Manual Rev. P1D 2000-05 5 - 1
Repeater Design
The repeater is housed in a cast aluminium chassis that is waterproof,
class NEMA4/IP65, for outdoor use. The chassis has a design suited for
outdoor use as well as indoor use.
The chassis consists of a cabinet and a cover joined with hinges. The
cabinet contains the repeater circuitry. The cover can either be a thin
cover or a large cover. The latter consists of another cabinet which can
be used as an empty cover or be equipped as an independent repeater unit.
The cover has two external LEDs for operation and alarm indication.
The cabinet as well as a large cover can be equipped for band selective
operation with adjustable bandwidth. A combined repeater can be
equipped for different bandwidths or different systems.
Both the uplink and downlink circuitry is built up on a single BSC board
inside the repeater. The various amplifiers and RF modules are
individually shielded by metal covers.
The BSC band selective compact repeater board
The band selective compact repeater board can handle one wide band
repeater channel, uplink and downlink. The band width is adjustable.
Other units
In addition to the BSC repeater board, the repeater contains:
•DPX Duplex filter, located on the upper part of the repeater.
•CMB Combiner unit, located on the RCC unit in repeaters with an RCC
unit that works in the same system as the repeater.
•RCC unit (optional), see Chapter 6, Optionals. This is located to the
right in the cabinet.
•PSM Power Supply unit, located to the left in the cabinet, and in the
cover, if equipped.
•The repeater is equipped with an R2R, Repeater to Repeater Link
feature that can be used between different repeaters or between the
cabinet repeater unit and the cover repeater unit.

Dual Band Repeater Units
Figure 5-2 shows an example of a combined band selective repeater for
dual bands. The repeater part in the cabinet is equipped with an RCC
unit that is used for communication between both the repeater parts via
the R2R feature. This feature can also be used to communicate with other
repeaters, ALR Compact repeaters as well as standard AR repeaters.
Both the BSC boards are used for band selective systems with an
adjustable bandwidth within 890 – 915MHz uplink and 935 – 960MHz
downlink.
If both the repeater parts are linked to the same base station, then the BS
antenna cables are connected to the same antenna via a combiner unit
(CMB). Otherwise separate antenna cabels are used from the repeater to
the antennas.
If both the repeaters cover the same area, then the same thing is
applicable to the MS antenna cables.

Band Selective Compact Repeater Block Diagram
Figure 5-3 shows a block diagram of the band selective compact repeater.
This diagram is applicable to repeaters for e.g. NMT, TACS/ETACS and
AMPS/DAMPS systems.
Downlink signal path
The signal from the base station is received via the repeater BS antenna
and is forwarded through a combiner (CMB) to the ANT input of a duplex
filter (DPX). The signal from the LO output of the duplex filter is, via
the P126 port, fed to the BSC board. On the BSC board, the signal is
amplified in a low noise amplifier (LNA) and is then entered the band
selective amplifier circuitry.
The first mixer stage in the BSC amplifier, which is controlled by a
synthesizer, converts the received frequency down to the IF frequency.
The signal is then filtered by a SAW bandpass filter and, not shown in the

figure, amplified before it is fed to the second mixer stage, controlled by
the same synthesizer as the previous one, for converting back to the
original frequency.
The SAW filter is adjustable and can be software changed from within
OMT32 (or OMS) to cover various band widths.
The following power amplifier (PA) is controlled by the Control Unit
(CU). The output gain can be reduced to avoid instability due to poor
antenna isolation.
A detector in the PA stage measures continuously the output level. The
signal from this detector is used by the automatic gain control, AGC, to
supervise and, if necessary, reduce the output power to keep it under a
maximum level. The AGC gain control affects all the amplification stages.
The output signal from the BSC board is taken from the P128 port and it
is fed to the HI port of a duplex filter (DPX). The output signal from the
ANT port of the duplex filter is fed to the repeater MS antenna.
RCC
The optional RCC Remote Communication Control unit is located inside
the repeater, see Figure 5-1 on page 5-3.
Communication with the base station is performed by means of a built-in
mobile feature that has the antenna connected to the BS combiner
(CMB). Data is transferred between the repeater CU and the built-in
mobile feature via the P130 port.
The RCC unit is powered via the P130 port and the unit has a battery
with capacity to send a number of alarms if a mains power failure occurs.
R2R
The Repeater to Repeater Link feature makes it possible to communicate
with a number of repeaters via one RCC unit in one of the repeaters in an
R2R net. Several RCC units can be used in the same net.
The repeaters in the R2R net are connected to the P118 port and to the
P124 port.
The R2R feature is further described on page 5-18.

repeater network with up to 13 repeaters, one or several of which can
contain a phone line for communication with an OMT32 or an OMS.
All Allgon standard Compact repeaters include this feature.
All Allgon repeaters can be mixed in R2R nets (see Figure 5-9). For
standard AR repeaters, the R2R Repeater to Repeater Link feature is
optional and require certain hardware and CU software versions.
Installation
All required R2R, Repeater to Repeater Link, circuitry is included in the
compact repeater. Only interconnecting cables are required to set up an
R2R net.
At least one RCC unit (or telephone line with modem) is required for the
remote communication.
Configuration
Configuration is described in AR Repeaters and OMT32, User’s Manual.

RCC, Remote Communication Control Unit
As the mobile phone technology is developing very fast, this RCC may be
modified after issuing this manual. New types may also have been added.
For the latest details, please contact your local Allgon representative.
For remote control of Allgon Compact repeaters in band selective systems
an RCC Remote Communication Control unit is available. This unit
contains an integrated mobile phone, modem and power supply backup.
The RCC unit for the Compact repeater is mounted to the right inside the
repeater cabinet, see Figure 6-1.
The RCC is connected to the P130 port as described in the Connection
section in Chapter 3.
Do not forget to put a jumper between pin 1 and 2 on the P130 connector if
the RCC unit is disconnected.
A jumper should be located in the P113 parking device (a 2-pole connector
used for this purpose).

OMT32, Operation and Maintenance Terminal
The OMT32, Operation and Maintenance Terminal is an Allgon software
package for configuration and controlling a repeater by using a computer
with Windows 95/98 or NT 4.
The OMT32 can be used either locally, i.e. connected to the repeater, or
remotely via an RCC unit or a traditional telephone line and modem.
All repeater parameters and settings can be configured by menas of the
OMT32.
OMS, Operation and Maintenance System
The OMS, Operation and Maintenance System is an Allgon software
package for controlling a large repeater fleet by using computers with
Windows NT in networks with a common database.
The OMS is capable of operating a large number of repeaters. Multiple
modems can be used for several incoming and outgoing parallel activities,
such as polling, radio parameter configuration, software downloading, etc.
Battery Backup
Battery backup can be arranged by completing the repeater with an 25Ah
or 50Ah Allgon BBU, Battery BackUp unit. The Allgon BBU has an
exterior similar to the repeater which means that it can preferably be
mounted adjacent to the repeater.
Fiber Optic Unit
A FOU, Fiber Optic Unit that includes transmitter, receiver, alarm board
and power supply is available for the Allgon Compact repeater. The fiber
optic interface can be adapted for separate uplink and downlink fiber as
well as for bi-directional one-fiber distribution.
7/16" Antenna Cable Connectors
A 7/16" antenna cable kit is available for the Allgon Compact repeater.
This kit includes 7/16" antenna connectors for uplink and downlink
antennas
