Antenna Installation

Installation of an antenna must comply with the FCC RF exposure requirements. The

antenna used for this transmitter must be mounted on permanent structures.

The FCC regulation mandate that the ERP of type A signal boosters should not exceed 5 W,

this is equivalent to 8.2W EIRP.

Therefore the max antenna gain allowed for this type of signal booster should be limited to

the values given by equation (1) for the service antenna and equation (2) for the donor

antenna

Equation (1) - Max SERVICE antenna gain

Max SERVICE antenna gain (dBi) = 39.1 – (37dBm - # of antennas in dB – cable losses in dB).

For example:

No. of Antennas

Cable Losses

Max Allowed Antenna Gain

39.1 - (37-6-3) =11.1dBi

39.1- (37-0-3) = 5.1dbi

39.1- (37-10-3) = 15.1dbi

Equation (2) - Max DONOR antenna gain

Max DONOR antenna gain (dBi) = 39.1 – (27dBm - cable losses in dB).

For example:

No. of Antennas

Cable Losses

Max Allowed Antenna Gain

39.1 - (27-2) = 14.1dBi

Compliance with FCC deployment rule regarding the radiation

of noise

Good engineering practice must be used in regard to the signal booster’s noise radiation.

Thus, the gain of the signal booster should be set so that the ERP of the output noise from

the signal booster should not exceed the level of -43 dBm in 10 kHz measurement

bandwidth.

In the event that the noise level measured exceeds the aforementioned value, the signal

booster gain should be decreased accordingly.

In general, the ERP of noise on a spectrum more than 1 MHz outside of the pass band

should not exceed -70 dBm in a 10 kHz measurement bandwidth.

The CSR3x04 series of signal boosters have a noise level of -55 dBm in 10 kHz

measurement at 1 MHz spectrum outside the passband of the signal booster and an in-band

noise level at around -50 dBm in a 10 kHz bandwidth. Therefore, the noise at the antenna

input port should be calculated based on equation (3).

Equation (3) - Input Noise to service antenna

Input Noise to service antenna:

-55 dBm + Service Antenna gain – Antenna splitter losses in dB – cable loss in dB

AXELL CSR 3604-3304 UHF REPEATER

PRODUCT DESCRIPTION AND USER’S MANUAL

Example:

Signal booster connected to 10 service antennas with a 100m long ½ inch cable.

Losses of such a cable with the connectors = ~ 11dB

Gain = ~ 2 dBi

Assuming 10 service antennas: antenna splitter losses = 11 dB

Based on equation (3) Input antenna noise (to the antenna) = -55+2-11 -11=-75 dBm

The inband input noise to the antenna should be -50+2 -11-11= -70dbm

NOTE: In this example there is no need to add an external band pass filter to attenuate the out of

band noise.

Conclusion:

Good engineering practice requires that in general when the out of band noise measured at

the service antenna input is more than -70 dBm per 10 kHz measurement bandwidth, an

external band pass filter should be added to attenuate the out of band noise level.

All Axell Wireless repeaters include high selectivity duplexers and filters to attenuate the out

of band noise. Should additional filtering be required, we have a comprehensive range of

interference filters which can be supplied upon request.

Compliance with IC

Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type

and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential

radio interference to other users, the antenna type and its gain should be so chosen that the equivalent

isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner

avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par

Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des

autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope

rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une

communication satisfaisante.

The Manufacturer's rated output power of this equipment is for single carrier operation. For

situations when multiple carrier signals are present, the rating would have to be reduced by

3.5 dB, especially where the output signal is re-radiated and can cause interference to

adjacent band users. This power reduction is to be by means of input power or gain reduction

and not by an attenuator at the output of the device.

This equipment complies with IC RSS-102 radiation exposure limits set forth for an uncontrolled

environment. This equipment should be installed and operated with minimum distance of 47cm

between the antenna and your body,

La puissance de sortie nominale indiquée par le fabricant pour cet appareil concerne son

fonctionnement avec porteuse unique. Pour des appareils avec porteuses multiples, on doit réduire la

valeur nominale de 3.5dB, surtout si le signal de sortie est retransmis et qu'il peut causer du

brouillage aux utilisateurs de bandes adjacentes. Une telle réduction doit porter sur la puissance

d'entrée ou sur le gain, et ne doit pas se faire au moyen d'un atténuateur raccordé à la sortie du

dispositif.

Cet appareil est conforme aux limitations de la norme IC RSS-102 concernant l’exposition aux

radiations dans un environnement non contrôlé. Cet appareil doit être installé et utilisé avec une

distance minimale de 47cm entre l’antenne et le corps de l’utilisateur.

General Safety Warnings Concerning Use of This System

Always observe standard safety precautions during installation, operation and maintenance

of this product. Only a qualified and authorized personnel should carry out adjustment,

maintenance or repairs to the components of this equipment.

NOTE: Please refer to Axell Wireless for additional information and for requests for

notifications to authorities.

Caution labels!

Throughout this manual, there are "Caution" warnings. "Caution" calls

attention to a procedure or practice, which, if ignored, may result in injury

or damage to the system, system component or even the user. Do not

perform any procedure preceded by a "Caution" until the described

conditions are fully understood and met.

Danger: Electrical Shock

This equipment can either be installed indoors or outdoors. When

installed outdoors - wet conditions increase the potential for receiving an

electric shock when installing or using electrically powered equipment. To

prevent electrical shock when installing or modifying the system power

wiring, disconnect the wiring at the power source before working with un

insulated wires or terminals.

Caution: RF Exposure

RF radiation, (especially at UHF frequencies) arising from transmitter

outputs connected to AWL’s equipment, must be considered a safety

hazard.

This condition might only occur in the event of cable disconnection, or

because a ‘spare’ output has been left un-terminated. Either of these

conditions would impair the system’s efficiency. No investigation should

be carried out until all RF power sources have been removed. This would

always be a wise precaution, despite the severe mismatch between the

impedance of an N type connector at 50Ω, and that of free space at

377Ω, which would severely compromise the efficient radiation of RF

power. Radio frequency burns could also be a hazard, if any RF power

carrying components were to be carelessly touched!

Where the equipment is used near power lines or in association with

temporary masts not having lightning protection, the use of a safety earth

connected to the case-earthing bolt is strongly advised.

For FCC compliance, the Maximum Channel output must be <5W ERP.

Warning: Antenna

Installation

Antenna positions should be chosen to comply with requirements (both

local & statutory) regarding exposure of personnel to RF radiation. When

connected to an antenna, the unit is capable of producing RF field

strengths, which may exceed guideline safe values especially if used with

antennas having appreciable gain. In this regard the use of directional

antennas with backscreens and a strict site rule that personnel must

remain behind the screen while the RF power is on, is strongly

recommended.

Installation of an antenna must comply with the FCC RF exposure

requirements.

The antenna used for this transmitter must be mounted on outdoor or

indoor permanent structures. The maximum antenna gain for indoor

operation is 2.2 dBi. In indoor applications the antenna must be installed

at a minimum separation distance of 47 cm from all nearby persons.

PRODUCT DESCRIPTION AND USER’S MANUAL

1 Introduction

The Axell CSR 3604-3304 (Channel Selective Repeater) is a repeater operating in the UHF

bands of 450MHz to 510MHz. Channel selective repeaters are mainly used for in-building

coverage, as well as coverage of dead zones, shadows, or other uncovered patches within

the current coverage area. The gap-filler repeaters can be used as a complement to the

network of base stations. They acquire their signal over-the-air from the Base Station and

transmit over the designated coverage area via service antennas.

A range of CSR repeater models are available for various site coverage requirements. This

manual describes the installation procedure for the US market.

PRODUCT DESCRIPTION AND USER’S MANUAL

10 DOC PN 3633B-UM Rev. 2.1 © Axell Wireless Ltd

2.3 RF Cabling Requirements

 For all coaxial connections to/from the Repeater - high performance, flexible, low loss

50Ω coaxial communications cable.

 All cables shall be weather-resistant type.

 Cable length - determined by the Repeater installation plan. When calculating the cable

length, take into account excess cable slack so as not to limit the insertion paths.

 Make sure that cable and connector are compatible. Using cables and connectors from

the same manufacturer is helpful.

 All connectors must be clean and dry

 Waterproof all outdoor connections using silicone, vulcanizable tape or other suitable

substance as moisture and dust can impair RF characteristics.

 Make sure enough room has been allocated for the bending radius of the cable. RF

cables must not be kinked, cut or damaged in any way

 Connect the RF cable to the antenna tightly but without damaging threads

 Fasten cables tight to cable ladder or aluminum sheet

 For short length of feeder cables use ½ “, for longer feeder cables use 7/8”. Chose

thicker coax cables for lower attenuation. Minimize the length of the coax cables to

reduce the attenuation

 Use jumper cable for easy installation. The RF Coaxial cable can be substituted at each

end with a jumper cable.

AXELL CSR 3604-3304 UHF REPEATER

PRODUCT DESCRIPTION AND USER’S MANUAL

3 Pre-Installation Requirements

3.1 Safety Guidelines

Before installing the Repeater, review the following safety information:

 Follow all local safety regulations when installing the Repeater.

 Only qualified personnel are authorized to install and maintain the Repeater.

 Ground the Repeater with the grounding bolt located on the underside of the Repeater.

 Do not use the grounding bolt to connect external devices.

 Follow Electro-Static Discharge (ESD) precautions.

3.2 Required BTS Information

Required BTS Information

 BTS channels

 BTS output power per channel

 BTS antenna gain

 BTS antenna height

 Distance from Repeater site to BTS

3.3 Selecting a Location

Select a location that will take into account the following criteria:

 Relative location of Base Station

 Cooling and airflow

 Wall compatibility

 Access to the repeater for installation or maintenance

3.3.1 Relative Location of Base Station

The repeater site shall be located where the BTS signal strength is great enough to be

recognized by the system. For example, a CSR 3604-3304 (85dBm max gain) and signal

strength of -70dBm at the pickup antenna, a gain in the pickup antenna of 10dBi, a repeater

gain of 85dBm and a server antenna gain of 2dBi the resulting ERP would be 27dBm.

Losses in cables and other elements would change these figures slightly.

 Repeater location near enough to BTS for received signal to be of adequate strength

 Ideally the repeater’s donor antenna should have line of sight (LOS) contact with the

BTS antenna. If the signal strength is high enough, LOS may in some cases not be

necessary.

 Distance from antenna site - It is recommended that the installation location be as close

as possible to the antenna site in order to maintain the cable loss to a minimum.

3.3.2 Cooling and Airflow

 Install the Repeater in a shielded, ventilated, and easy-to-reach area.

 The Repeater is convection cooled so airflow and alternation should be possible.

 Verify that ambient temperature of the environment does not exceed 50C (122F)

Mount the repeater so that heat can be dispersed from it. The repeater wall mounting kit

ensures an optimum airflow between the wall and the repeater itself. Do not block this air

AXELL CSR 3604-3304 UHF REPEATER

PRODUCT DESCRIPTION AND USER’S MANUAL

12 DOC PN 3633B-UM Rev. 2.1 © Axell Wireless Ltd

channel as it will cause the MTBF of the repeater to drop dramatically, or even in the worst

case cause the repeater to fail completely.

If possible use a wall in the shadow to minimize the overall sun loading. If sufficient

shielding cannot be obtained, an additional sun shield should be mounted.

3-1. Example of a sun shield outdoors

Operating Temperature

The CSR repeaters are designed primarily

for multi carrier purposes. If the repeater is

run at full output power over a long period of

time the convection cooling might not be

enough. The repeater has a power

management function implemented that will

step down the power and if needed fully shut

down the amplifier chains until temperature

has reached normal values. In situations

where a repeater will be run in such a

manner extra cooling can be provided for

instance by putting the repeater in a

temperature controlled environment or via

external fans.

3.3.3 Wall Compatibility

 Check the suitability of the wall on which the Repeater is to be mounted.

 The Repeater wall mount brackets assembly should be fixed to a solid wall (these

include brickwork, blockwork, and concrete.);

 (Due to the weight of the Repeater, it is NOT recommended to fix to a hollow wall).

3.3.4 Access to the Repeater

 Plan connection cable clearances - the Optical, RF and power connections located on

the underside of the Repeater will need at least 300mm vertical clearance below the

Repeater to enable the connections to be made. The minimum bend radius for Optical

and RF cables must not be less than the recommendations made by the cable

manufacturer. Plan the cable runs and ensure adequate space is available.

 Allow for door opening - ensure that there is sufficient space at the front of the

Repeater to allow the door to be fully opened and for maintenance engineers to get

access to the unit with test equipment such as a spectrum analyser.

 Allow space around the repeater - verify that there is a minimum of a 50 cm (20”)

radius of space around the Repeater, enabling easy access to the repeater for

maintenance and on-site inspection. Allow an additional 50 cm of space in front of the

Repeater when the door is fully open.

 Monitoring repeater - install the Repeater close to the service area to monitor the

output power.

4.7 EMV Protection

CAUTION! If insufficient Electromagnetic Protection is provided,

or if EMV measures are not taken, warranties issued by Axell Wireless

are not valid.

The lightning hazard to electric and electronic equipment consists in the interferences of

direct lightning current infections and high surge voltages induced by the electromagnetic

field of nearby lightning channels or down conductors. Amplitudes from cloud-to-earth

lightning amounts to several 10kA and may last longer than 2(ms). The damage caused

depends on the energy involved and on the sensitivity of the electronics systems.

Ensure that lightning protection measures are taken to create a reliable repeater site.

Protect all coaxial cables and power cables from the transients caused by lightning. Fit all

cables with suitable lightning protection devices.

For detailed information please refer to IEC 61024-1 and 61312-1 for international standards

for protection of information systems against LEMP, Lightning Electromagnetic Pulse,

including radio transmitters. They define proper planning, installation and inspection of

effective lightning protection systems.

6.3 CSR Channel Configuration

The initial setup procedure consists of defining the required VHF channels. Up to eight

channels can be defined, where each channel is defined according to the following

parameters:

 UL center frequency and DL center frequency

 Type of channel according to usage (High Selectivity or Low Delay)

 Attenuation

 Power level

To configure channel RF parameters

1. Access the Home screen (displayed by default).

A partial image showing only the channel definitions area is illustrated below.

2. Define the Downlink and the Uplink parameters for each required channel:

 Set the Centre frequency.

 Set the type of Filter to Low Delay or High Selectivity according to site requirements.

 Set the Power Level according to the following options:

 Max – maximum power available according to the number of active channels.

 Max-1 to Max-9 – from 1 to 9 dBm less than the maximum power according to

the number of active channels.

 OFF – no power is transmitted on corresponding UL or DL channel.

NOTE: Be sure to disable inactive channels by setting the Power Level to OFF.

Set the Attenuation as follows:

Under the selected Chain (channel), in the Downlink section, set DL Attenuation

to the maximum value. The values shown in the figure below are for example

only.

Lower the Attenuation level step by step until the desired output power level is

reached (zero attenuation = maximum gain).

NOTE: Since the base station is more sensitive than a mobile unit there may be less signal

gain from the mobile unit in to the base station (UL) than in the opposite direction. The

uplink attenuation can be adjusted more accurately later on, once test signal measurements

have been completed.

PRODUCT DESCRIPTION AND USER’S MANUAL

6.6 Integration into the AEM

When the repeater has been installed at site and the remote communication has been

enabled, the repeater can be integrated to the Axell Element Manager. This is done by the

operator of the AEM. After entering the telephone number to the repeater, the AEM dials up

the repeater, downloads all the repeater parameters and statuses into a database. When all

parameters have been downloaded, the AEM configures the repeater with the telephone

number where alarms and reports should be sent, and optionally with a secondary

telephone number where the repeater can dial in case connection to primary number fails.

When heartbeat reports and alarms are sent from the repeater to the AEM also the latest

information about the status and RF-configuration is included. This means that the AEM

operator always has information about the current status in the AEM database (and do not

need to call the repeater to find this out).

NOTE: Once the repeater is integrated to the AEM, all changes to the repeater should

preferably be done from the Axell Element Manager in order to ensure that the database

always contains correct information.

8.3 Troubleshooting Remote Communication

Please also refer to the document Common Command and Attributes for guidance.

Since many networks have their own “personality”, performing first time configuration of the

remote communication sometimes requires tweaking of the modem parameters.

This section describes some trouble shooting techniques if configuring the repeater for

remote access fails.

The illustration below is a simplified schematic of the remote communication between a

GSM modem in a repeater and an analogue modem. The analogue modem in the computer

communicates with the Interworking Function Unit (IFU), which is the GSM network

analogue network interface. The call is routed via the switch centre over the air interface to

the data call number in the SIM-card of the GSM module.

The Control Module is responsible for establishing connections with the Axell Element

Manager, and to answer incoming calls to the repeater.

As described in previous sections, the Control Module only accepts one login at a time,

either via Local Maintenance port (LMT) or modem connection. Hence, when verifying the

remote access of the repeater, it is important to log out from the repeater locally before

trying to access the repeater remotely.

8.3.1 Direct Modem Access

To allow for advanced trouble shooting of the communications, it is possible to connect

directly to the modem by opening the repeater and connecting to the Control Module from a

computer.

HyperTerminal™.

When the login is completed, select Terminal Mode, this will give access to the repeater

command prompt in the same way as with HyperTerminal.

When the repeater prompt is accessible, type in the command

ACCESS MODEM <Enter>.

AXELL CSR 3604-3304 UHF REPEATER

PRODUCT DESCRIPTION AND USER’S MANUAL

When typing ACCESS MODEM, the controller will send all the characters that are typed

directly out to the modem port. All characters replied back from the modem will go directly to

the LMT port and back to the computer.

To abort an ACCESS MODEM session, press three ‘-‘ in a row (all three within one second)

to come back to the repeater command prompt.

NOTE: When accessing the modem port the modem might be configured with “echo off”,

meaning that the characters entered will not be echoed back to the screen. In order to

enable “echo”, press Enter.

Type

ATE1 <enter>

(invisible)

The modem replies with

indicating that the echo is enabled. All characters entered will now be echoed back to the

terminal program.

8.3.2 Trace Modem

For troubleshooting purposes it is possible to trace the actual progress of initializing the

modem. This trace is useful when having problems with the modem initialization.

Go to Terminal Mode and type

TRACE MODEM

To end session type CTRL-Z

AXELL CSR 3604-3304 UHF REPEATER

PRODUCT DESCRIPTION AND USER’S MANUAL

8.3.3 Manually Answering Incoming Calls

It is possible to manually answer incoming calls without involving the repeater software at

all, to verify that the remote access and the network itself works as intended. In order to

verify the remote communication, make sure to have someone stand by to dial up the

repeater with a terminal emulation program, for example HyperTerminal™.

Go in to Direct Modem Access as described earlier. When in direct access mode, ask the

person standing by to dial up the repeater.

As soon as a call is received, the text RING will repeatedly be displayed on the screen.

Type ATA <enter>

This will inform the modem to answer (ATtention Answer).

When the connection is established, a connect message will be displayed including the

connection speed. Sometimes the information comes together with some miscellaneous

information, such as error correction protocols etc.

NOTE:Make sure the remote peer dials the Data Call number

If the voice number is dialed instead of the data number, or if the modem contains an illegal

modem initialization string, the message

NO CARRIER

will be displayed almost immediately.

Try to change the modem initialization string. The modem initialization string mainly used to

configure the remote communication is AT+CBST.

Successful modem initialization strings used by Axell Wireless includes (most common first):

AT+CBST=71,0,1;\Q3

AT+CBST=7,0,1;\Q3

AT+CBST=0,0,1;\Q3

AT+CBST=7,0,3;\Q3

Once the modem initialization string is entered, try again to dial up the repeater. For details

on the different modem initialization strings, please refer to the modem’s user guide.

If the setup is successful, the connect message will be brought up;

CONNECT 9600

This means that an online connection is established to the remote peer. From now on, all

characters typed on the keyboard will end up on the remote peer’s screen. Similarly, all

characters typed by the remote peer will be displayed on the screen.

In the example, the incoming

call was successfully answered,

and the remote user entered the

text message.

In order to come back to modem command mode, press +++ (three pluses) rapidly (within

one second).

Receiving OK means that the modem is back in command mode.

Type ATH <enter>

This terminates the connection to the remote peer. The message NO CARRIER will be

displayed.

PRODUCT DESCRIPTION AND USER’S MANUAL

8.3.4 Common Problems

8.3.4.1 Problem 1

When enabling the remote access for the repeater, the modem fails to log in to the network.

8.3.4.2 Solution

Signal strength from the donor site is too low. The signal strength can be read directly from

the modem. Go in to Direct Modem Access as described earlier. Use the command

AT+CSQ (documented below) to read out the signal strength.

In order to have good signal quality, Axell Wireless recommends that the signal strength

should be better than -95 dBm. If signal strength is lower, try to adjust the antennas to get a

better signal strength from the donor.

Documentation of +CSQ command from a modem’s manual.

In the example the reply to

AT+CSQ is 0,7 meaning 7*2 dB

above -113 dBm; the modem

detects a signal level of -99

dBm.

AXELL CSR 3604-3304 UHF REPEATER

PRODUCT DESCRIPTION AND USER’S MANUAL

8.3.4.3 Problem 2a

Repeater is configured properly, and answers the incoming call, but when trying to dial the

repeater using an analogue mode, no modem handshaking is heard from the dialing

modem.

8.3.4.4 Problem 2b

When dialing the repeater, the repeater answers the incoming call, but no connection is

established, and after a while the repeater disconnects the call.

8.3.4.5 Solution

The most common cause is that the number called is the voice number of the SIM, not the

data number. Therefore, make sure to dial the data number.

If data call is used, the problem probably is an illegal modem initialization string.

In order to change the modem string, go to the repeater command prompt. Try changing the

modem initialization string and log out to let the controller reinitialize the modem.

If problem remains, try a few different modem initialization strings. Axell Wireless has been

successful with the following modem initialization strings:

AT+CBST=71,0,1;\Q3

AT+CBST=7,0,1;\Q3

AT+CBST=0,0,1;\Q3

AT+CBST=7,0,3;\Q3

Please refer to the modem manual for detailed description of the modem initialization

strings.

8.3.4.6 Problem 3

It is possible to call the repeater from another GSM mobile, but not from an analogue

modem.

8.3.4.7 Solution

This problem is most likely related to the modem configuration and/or the configuration of

the IFU unit. Try to decrease the communications speed and make sure that the modem

error correction is supported by the IFU. Verify the IFU configuration to see if there are any

known problems with the modem connections.

8.3.4.8 Problem 4

When dialing the repeater, or when the repeater is dialing the Element Manager, the

connection is terminated before the handshaking is completed.

8.3.4.9 Solution

When a repeater is answering an incoming modem call, or calling up the OMC to deliver an

alarm or a report, the repeater will wait a configurable number of seconds for the call to be

established. If no communication is established within this time, the call will be hung up. If

this interval is set too low, the handshaking is terminated too fast. In the RMC, verify the

Modem Connect Time to see that it is set to at least 30 seconds.
