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 mandates that the EIRP of type B signal boosters should not exceed
5W.
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) = 37 – (33dBi - # of antennas in dBi – cable losses in dBi).
For example:
No. of Antennas Cable Losses Max Allowed Antenna Gain
4 3 37 - (33-6-3) = 13dBi
1 3 37- (33-3) = 7dBi
10 3 37- (33-10-3) = 17dBi
Equation (2) - Max DONOR antenna gain
Max antenna gain (dBi) = 37 – (27dBi - cable losses in dBi).
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 EIRP 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 3709 signal booster has a noise level of -50 dBm in 10 kHz measurement at 1 MHz
spectrum outside the passband of the signal booster and an in-band noise level at
around -34 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:
-43 dBm + Service Antenna gain – Antenna splitter losses in dBi – cable loss in dB
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) = -51.1+2-11-11=-71.1 dBm
The inband input noise to the antenna should be -32+2 -11-11= -52 dbm

PRODUCT DESCRIPTION AND USER’S MANUAL
VI Doc PN 00038UMCD Rev. 1.6 © Axell Wireless Ltd
NOTE: In this example there is no need to add an external bandpass filter to attenuate the out 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.
General Safety Warnings Concerning Use of This System
Always observe standard safety precautions during installation, operation and
maintenance of this product.
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 must be installed only indoors. 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, 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 50 ohm, and that of free space at 377
ohm, 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!
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.
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.

performance when operated in conformity with their intended
design. However, a semiconductor may be damaged by an
electrostatic discharge inadvertently imposed by careless
handling.
Static electricity can be conducted to the semiconductor chip from
the centre pin of the RF input connector, and through the AC
connector pins. When unpacking and otherwise handling the
repeater, follow ESD precautionary procedures including use of
grounded wrist straps, grounded workbench surfaces, and
grounded floor mats.
Caution: Battery
Replacement
Risk of explosion if battery is replaced with incorrect type. Dispose
of used batteries according to instructions.

This manual describes the Axell D-SBR 3709S IP65 High Power Digital Channel/Band
Selective Repeater. The repeater is designed for indoor installations and includes
advanced filtering capabilities to support the SMR 900MHz band for public safety and
commercial operations.
The D-SBR 3709S repeater supports up to eight non-contiguous sub-bands/channels,
where the gain and output power of each sub-band is independently tunable across the
entire band. This provides an optimal solution for operators that have a non-contiguous
spectrum.
The system supports advanced Digital Signal Processing (DSP) technology,
programmable digital filters. These capabilities enable the user to quickly and simply
customize the Repeater according to changing site requirements.
Highly linear MCPA components and unparallel innovative DSP filtering provide top level
performance that support high throughput of the latest modulation technologies such as
HSPA and LTE.
The Smart-ALC power control algorithm automatically optimizes the gain setting by
learning the actual range of RSSI levels over a user-specified period of time. The Smart-
ALC algorithm prevents oscillations, reduces the amount of isolation required by the
system and optimizes the system to minimize noise rise at the donor cell site.
Intuitive Web access monitoring and management GUI is accessible via a local or
remote Ethernet connection.

• 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.
• 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.
• The Repeater is convection cooled so airflow and alternation should be possible.
• Follow Electro-Static Discharge (ESD) precautions.
• Install the Repeater close to the service area to monitor the output power.
• Use low loss cables to connect the antennas to the Repeater.
2.3.4 RF Cable Installation Guidelines
• For all coaxial connections to/from the Repeater - high performance, flexible, low
loss 50 ohm 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.

WARNING! Perform this procedure before connecting the antennas to the Repeater or
powering on the Repeater. The Repeater should not be operated prior to the verification of the
operating parameter in its installation environment.
Before connecting the antennas or power, verify isolation between the donor and
mobile antennas
The isolation between the Base/Donor and Mobile/Service antennas is critical.
• For proper operation of the Repeater, it is recommended that the isolation between
the Donor and Service antennas be at least 12dB higher than the Repeaters set gain.
• Insure proper vertical or horizontal distance separation between Donor and Service
antennas
NOTE: Lower isolation can lead to high in-band ripple, oscillations and low signal quality.
To measure the isolation, proceed as follows:
1. Inject a known signal from a signal generator into one antenna (preferably the
Donor antenna).
2. Measure the coupled output from the Service antenna, using the Spectrum analyzer
and LNA if applicable.
3. Perform this procedure across the frequency range of both the Uplink and Downlink
bands.
4. Register the lower result for system operation.

4.3.2 Adjusting the Signal Levels and Configuring Channels
The Control and Params (parameters) window is used to configure each of the
supported band's sub-bands and Max UL/DL Power. This section describes each of the
fields.
Each sub-band is individually defined by setting the following:
• Bandwidth (start and stop frequency)
• Maximum power
• Maximum gain
• Gain delta (used for noise control)
The defined sub-bands are displayed in the lower part of the screen for reference.
To adjust the signal levels and configure the channels
Note: Be sure to click Send with each change.
1. In the topology tree, click Root, then click CMU and then click the repeater Band.
2. Click the Control and Params tab. The corresponding pane appears.
The window is divided into the following areas:
• System – overall parameters for the service.
• Sub-band (filter) definitions – used to define up to eight sub-bands and
their RF parameters.
• Sub-bands view – graphical display of defined sub-bands for the service.
3. Set the System Level parameters:
• Verify that the RF Transmission Enable parameter is checked.
• Set the Max Composite DL Output Power according to your site
requirements and click Send. The Measured Composite DL Output Power is
displayed in the adjacent field.

If the composite output power exceeds the defined value, the Smart ALC
feature begins working.
• Set the Max Composite UL Output Power according to your site
requirements.
Additional parameters (not required for initial setup) are:
• Oscillation Prevention Enable - Enables oscillation detection mechanism
that maintains repeater functionality.
• Temperature - Displays Repeater ambient temperature.
• DL Output Threshold Delta (dB) - the delta from the set Composite Output
Power, below which the alarm 'Donor power is too low' is activated.
For example, if the DL Output Threshold value is set to 8dB, when the
Measured Composite DL output power is 8dB less than the set Composite
Output Power, an alarm is generated.
• Meas. Composite DL Output Power – displays the currently measured
output signal level.
4. To configure each sub-band:
• Checkmark Enable. The configuration parameters in that row will be
available.
• In the Downlink area, set the Start and Stop DL Frequency (MHz). (The
Uplink Start and Stop frequencies will be automatically allocated.)
The defined BW will be displayed in the BW KHz column (to the left of the
Start Frequency).
Be sure to choose Start/Stop values displayed in the Band Info tab.
• Set the (Downlink) Max Gain as follows: by default, the MAX Gain (DL)
parameter is set to its highest level (90dB). Change the Channel Max
Gain (DL) according to the measured/calculated input power and isolation
measurements.
• The recommended Maximum Gain setting is approximately 12 dB less than
the isolation between the service and donor antennas.
5. If the site NOISE LEVEL is high enough to cause interference, adjust the noise level
as follows:
• Adjust the Gain Delta parameter – this sets the delta between the uplink
and downlink gain (so the uplink gain is relatively lower than the downlink
gain.
• Click Send.
• Repeat the procedure until the desired coverage is achieved.
6. More information on parameters for the selected sub-band:
• DL Set Ch. Max. Gain Sets the power for the antennas. The value is about
15 dB less than the isolation between the donor antenna and the mobile
antenna.
The Value defined in the DL path is reflected in the UL path, however to
define different UL and DL path values the Gain Delta parameter is used and
its defined value is added to the UL value.
• DL Measured RSSI - measured DL signal.
• DL Measured Ch. Gain - measured DL Gain (dB) for the selected sub-
band.
• DL Measured Ch. Power - measured Power (dBm) for the selected sub-
band.

4.5.2 IP Address Setup and Repeater Name
The Repeater supports both Static and DHCP addresses. A unique technology enables
applying both types to the same Ethernet port. Both addresses may enable local and
remote management.
• Local IP Address – Static IP assigned by the user to the system. The default Static IP
address is 192.168.1.253. It is highly recommended to preserve this setup. In case
of a change, make sure you record the newly assign IP.
• DHCP Address – address assigned by DHCP server – used for remote management
via an Ethernet connection.
To assign the unit a name and IP address
1. Access the Communication tab according to section 4.5.1.
2. To assign the unit addresses:
• Local address - in the IP Configuration area, assign the unit the Local IP
address, Netmask and Gateway parameters provided by your system
administrator.
• DHCP server address – checkmark the option Request Additional DHCP
Address. The assigned address can be seen in the DHCP Address field.

4.5.3 AEM (Axell Element Manager) Configuration
AEM repeater management configuration is performed only on the AEM side – it is only
required to add the new repeater (element) IP address to the AEM.
This section describes how to configure the repeater for Auto Replacement. Auto
Replacement is used when a repeater is replaced. The new repeater is assigned the
same IP address as the previous repeater and configured with Auto Replacement. This
enables the AEM to download the previous repeater configuration to the new repeater,
minimizing downtime.
To configure the repeater for AEM management
1. Access the Communication Configuration tab (see 4.5.1).
NOTE: The RID (Repeater ID) is automatically detected by the system.
2. To configure the replacement Repeater for Auto Replacement:
• Set Auto Replacement to Enable.
• Set Site UID Type to LAN IP – this identifies the site IP Address
• Verify that the repeater’s IP address is Fixed – section 4.5.2.

Alarm
Fault and most probable
cause Recommendation
System Mute
Cause: Repeater amplification is
muted (automatically). -----
User Mute
Cause: Repeater amplification is
muted (manually) as a result of
an operator action.
-----
Built In Test Cause: Self test. -----
Temperature Fault: High temperature.
Most probable cause: Unit
temperature becomes high.
Excessive heat.
Corrective action: Check the Repeater
case for external causes (sun, hot
environment, air flow is blocked).
Eliminate the reason for excessive
heat.
Donor Power too
Low
The signal from the Donor
antenna is too low. Check connections and antenna
position.
PAmp Current Fault:
the Pre Amplifier current
exceeds the allowed limits.
Fault in the DL or UL path.
Most probable cause:
Downlink (Uplink) power
amplifier module outputs a low
current.
Corrective action: Check the LEDs in
the Repeater (see 6.1).
RSSI Fault: Fault in the DL or UL path
Most probable cause: Excessively
high input signal
Corrective action: Check the LEDs in
the Repeater (see 6.1).
VSWR
Fault: The return loss of the
Downlink antenna or cable
connection exceeds 6 dB (VSWR
3:1).
Most probable cause: This alarm
provides an indication of the
status of the cable connected to
the antenna. If a cable is
defective, the VSWR is decreased
and the alarm is triggered again.
Corrective action:
Check cable
connected to the antenna.
Reduced Gain by
IMOP Description:
Shows when the
iMOP mechanism was activated
in order to re
spond to detected
oscillations.
GREEN – normal operation – no
oscillations were detected.
RED – oscillations were detected
and the system reduced gain in
order to eliminate the
oscillations.
Corrective action: Check the Donor and
Mobile antenna installations for
isolation. After isolation is within the
required levels, the system will
automatically increase gain (since it
will no longer affect oscillations) and
the LED will turn GREEN.
Interferer Power
Exceeded
Indicates if there is any external
interference at a level that may
affect the operation of the unit.
Green –
low or no interference.
Unit operation is not affected.
Red –
high external interference
that may affect the operation of
the unit.
It is recommended to identify the
source of the interference and distance
the source or the unit from each other.
