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

Measuring the Output Power Level
Uplink and downlink output power test ports are found on the directional
couplers (DC) at the MS and BS antenna connectors. These test ports are
marked TEST –30dB (see Figure 4-1) and are intended for measuring
using e.g. a spectrum analyzer.
The coupling is –30dB approximately. There is no directivity in these test
ports, i.e. both uplink and downlink signal can be measured.
Voltage Supply Testpoints
A number of voltage supply testpoints are available in the repeater.
These testpoints are named U7A - U7F for the 7V supply voltages and
U26 for 26V, 13V or 10V supply voltage (depending on the repeater type).
A standard multi-meter can be used on these testpoints.
The testpoints are found on the DIA board in the repeater cabinet. The
testpoint positions on the DIA board is detailed in the Board and Unit
Descriptions section in Chapter 5.
If the repeater is equipped with a second PSU, e.g. for combined
channel/band selective operation, the same set of testpoints are also found
on the cover DIA board.
Repeater Configuration
The repeater is now ready to be configured in accordance with the site
conditions and system performance requirements. Pay especial attention
to the antenna isolation described in the OMT32, User’s Manual.
Commissioning AR Repeaters Allgon Systems AB
4 - 4 Rev. P1A 2000-09 User’s Manual VD203 66/EN
5. Functional Description
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, channel number, 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 System AB AR Repeaters Functional Description
User’s Manual VD203 66/EN Rev. P1A 2000-09 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 channel selective
operation or band selective operation. A combined repeater is normally
equipped for channel selective operation in the cabinet and band selective
operation in the cover.
Different amplifier boards are used to get the various operations (see
below). The amplifier boards are individually shielded and located under
metal cover sheets which can be folded out.
CHA, Channel selective GSM amplifier board
Channel selective GSM repeaters can handle up to eight repeater channels
(four if the CU part number is K103/1). For every even number of
repeater channels, two CHA amplifier boards are required in the repeater,
one CHA board for uplink signaling and one board for downlink signaling.
Each repeater channel is allocated to a radio channel or switched off. In a
GSM type TDMA system (GSM, EGSM, DCS1800 or PCS1900), one
repeater channel can handle eight calls (sixteen if half-rate encoding is
used).
CSA, Channel selective CDMA amplifier board
Current CDMA repeaters can handle two CDMA repeater channels. For
every even number of repeater channels, two CSA amplifier boards and
two PA amplifier boards are required in the repeater, one pair of CSA/PA
boards for uplink signaling and one pair for downlink signaling. Each
repeater channel is allocated to a radio channel or switched off.
BSA, Band selective amplifier board
Band selective repeaters can handle one wide band repeater channel. The
band width is either fixed or adjustable (fixed for 900MHz repeaters only).
A band selective repeater channel requires two BSA boards and two PA
amplifier boards in the repeater. One pair of BSA/PA boards for uplink
signaling and one pair for downlink signaling.
BA, High power CDMA booster amplifier board
CDMA repeaters can be equipped with a high power booster amplifier
board that boosts the output gain with typically 6dB. A high power
CDMA repeater can operate with maximum 2 channels.
Functional Description AR Repeaters ALLGON System AB

The first mixer stage on the CSA amplifier board, which is controlled by a
synthesizer, converts the received frequency down to the IF frequency.
The signal is then filtered by SAW bandpass filters and, not shown in the
figure, amplified before it is fed to the second mixer stage for conversion
back to the original frequency.
The following power amplifier is controlled by the CU. The output gain
can be reduced to avoid instability due to poor antenna isolation.
The output signal from the power amplifier is fed to a combiner, which
combines the signals from the two channels on the channel board.
A detector on the PA board 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 several of the amplification
stages.
BA in high power CDMA
repeaters only. In high power CDMA repeaters, a booster amplifier (BA) boosts the
output downlink signal by typically 6dB. The BA amplifier is powered by
a high power PSU2. Note that the booster amplifier (BA) is only present
in the downlink path, and only in high power CDMA repeaters.
The output signal passes a duplex filter (DPX) and a directional coupler
(DC) before it is fed to the repeater MS antenna.

The first mixer stage on the BSA amplifier board, which is controlled by a
synthesizer, converts the received frequency down to the IF frequency.
The signal is then filtered by SAW bandpass filters and, not shown in the
figure, amplified before it is fed to the second mixer stage for conversion
back to the original frequency.
The SAW filter can be either fixed or adjustable depending on the BSA
board used. If the BSA board has fixed band width, this SAW filter is
fixed and selected for the current band width. If the BSA board has
adjustable band width, the SAW filter combination can be software
changed from within OMT32 (or OMS) to cover various band widths.
The following power amplifier is controlled by the CU. The amplifier gain
will be reduced to avoid instability due to poor antenna isolation.
A detector on the PA board 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 several of the amplification
stages.
The output signal passes duplex filter (DPX) and a directional coupler
(DC) before it is fed to the repeater MS antenna.
RCU
The optional RCU Remote Communication Unit is located inside the
repeater (described in Chapter 6, Optionals).
Communication with the base station is performed by means of a built-in
mobile feature that has the antenna connected to the BS directional
coupler (DC). Data is transferred between the repeater and the built-in
RCU unit via the P32 modem port.
The RCU unit is powered via the P27 auxiliary 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 RCU unit in one of the repeaters in
an R2R net. Several RCU units can also be used in the same net.
The repeaters in the R2R net are connected to the P34 port.
The R2R feature is described in Chapter 6, Optionals.

Alarm
Alarm signals from external sensors are received by the ALI board, which
forwards the alarm signals to the CU board.
The software on the CU board is able to activate acoustic or visual alarm
or direct the alarm to the P33 alarm port to be forwarded, via the RCU
unit, to OMT32 (or OMS) located in an operation and maintenance
central.
Alarms can be configured from OMT32 (or from OMS).
Repeater Setup
The repeater parameters can be set locally by means of a desktop or
notebook loaded with the OMT32 software (or the OMS software). The
PC or notebook is connected to the CU via the P31 PC port (see
Figure 5-6, Figure 5-7 and Figure 5-8).
The repeater parameters can also be set remotely by means of a phone
(mobile or via a telephone line) and a modem connected to the CU board
via the P32 modem port (see Figure 5-6, Figure 5-7 and Figure 5-8).

cabinet. The CU board contains a microprocessor, main memory, flash
memory for the CU software, EEPROM memory for parameters, memory
for the event log and statistics, a REFO reference oscillator, ports for local
and remote communication, battery powered real-time clock, etc.
The CU board is used to supervise and control operational parameters
such as gain control, channel handling, etc. The CU takes care of alarms
and the event log, password and logon, and many other procedures.
The CU is also a control interface when using an OMT32/PC or OMS/PC,
locally or remotely via modem.
The CU software can be downloaded from an OMT32/PC or OMS/PC,
either locally or remotely.
The real-time clock on the CU board is used for alarm and for the event
log.
There are currently two CU board variants: K103/1 and K103/2.
CU board and CU software part #s
K103/1 CU board (old)
CU board K103/1 can be run with the SA102 01/2 CU software. This
board can store one version of CU software. The repeater will always
boot on this software version.
K103/2 CU board (current) CU board K103/2 can be run with either the old SA102 01/2 CU software
or the current SA102 02/1 or SA102 02/2 CU software. This board can
store two versions of CU software, located in segment 1 and segment 2 of
the flash memory as Application 1 and Application 2. The repeater will
boot on that software which is set as Primary (description of Primary
application is found in the OMT32, User’s Manual).
Compatibility for CU boards and CU software is detailed in the next
section.
Connection
The CU board is connected to the DIA board via the P2 port.
Caution
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.

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.
OMS is an improved OMC, Operation and Maintenance Center. The latter
is replaced by the OMS and is no longer subject to further development.
Traffic Statistics
Traffic statistics is available for channel selective GSM 900, GSM 1900
and DCS/PCN 1800 repeaters, provided that the repeaters have the latest
CU software versions, the latest CU and CHA boards, and that an OMS is
used to poll and view the statistics.
Battery Backup
Battery backup can be arranged by completing the repeater with an
Allgon UPS (Uninterruptible Power Supply). The Allgon UPS has an
exterior similar to the repeater which means that it can preferably be
mounted adjacent to the repeater.
Fiber Optic Interface
A Fiber Optic Interface that includes transmitter, receiver, alarm board
and power supply is available for all the Allgon repeaters. 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 all the Allgon repeaters. This kit
includes 7/16" antenna connectors for uplink and downlink antennas
mounted on two repeater cable inlet flanges, and cables and connectors
for connection to the DC directional couplers inside the repeater.
