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.
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 28 cm between the antenna and your
body,
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.
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 3.5 dB,
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 28 cm entre
l’antenne et le corps de l’utilisateur.

D-MBR 3707-3708 PS NFPA Class B Signal Booster
PRODUCT DESCRIPTION AND USER’S MANUAL
Cobham Wireless – Coverage Date: 6-Set-15 www.cobham.com/wireless
Doc. No. 00060CDUM Rev. 1.0 Page | 1
1 INTRODUCTION
This manual describes the installation and setup procedures for D-MBR Public Safety Signal Boosters
providing SMR 700 and 800MHz band at 37dBm output power per band.
D-MBR 3707-3708 PS NFPA (Digital Multi Band Booster for Public Safety) is a Class B Digital Multi-
Channel Signal Booster (DCSB). It features an array of up to 12 DSP based, software-controlled,
variable bandwidth filters, that are user-programmable across the 700 and 800 MHz bands.
D-MBR 3707-3708 PS NFPA supports all public safety technologies. For each filter, the user can
specify the start and stop frequencies to reduce the installation time of the signal booster and enable
a very wide range of filters selection.
Every parameter of D-MBR 3707-3708 PS NFPA, including filter tuning and selection, can be
controlled via web based management. The patented Cobham Wireless’ digital RF filter enables
simple initial setup for any channel plan and if necessary, allows some basic reconfiguration due to
re-banding.
The SALC -Smart ALC algorithm will reduce the gain to protect the signal booster from oscillation.
When the gain cannot be reduced anymore a shut-down mechanism will be triggered.
The signal booster protects against degradation of the system’s sensitivity and coverage. This is
implemented by the inbuilt AGC per-channel (filter) feature, which permits equalization of the
channel levels for uniform coverage.
This product meets the rigid requirements as defined by the NFPA and International Fire Code
developmental organizations. The amplifier is painted a Fire Life Safety Red, meets NEMA4
compliance for hose down, and provides all Alarming outputs as defined by NFPA 2010, Chapter 24
including system and antenna failures. The signal booster is a DC fed unit.
An external battery charger unit is available as well. The charger is connected to the AC and includes
a circuit to charge external batteries with all the dry contact alarms as defined in the NFPA standard:
AC failure, Charger failure and Low battery.
1.1 Main Features
• Class B- signal booster for SMR and public safety networks

1.4 Smart-ALC Function
The Signal Booster’s power amplifier includes power-monitoring circuits with Automatic Level Control
(ALC) that prevents excessive output power while maintaining the power amplifier linearity
The Smart Automatic Level Control (Smart-ALC) is an innovative algorithm for automatic Signal
Booster gain adjustment. Combined with advanced control algorithms, SALC is capable of learning
the traffic load characteristics and adjusting the Signal Booster RF Gain to the desired value.
Note: To reset the Signal Booster to its highest set gain value, disconnect the Signal Booster power
cable for several seconds and re-connect.
1.5 Power Feeder and Battery Charger
NOTE: The Power Feeder and Battery Charger is described in Chapter - 4).
For installations where UPS is not available, the AC Feeder and Battery Charger unit can be
purchased (see section 4.1 for ordering information).
The charger is connected directly to the AC inlet and includes a circuit to charge external batteries
(meeting the specifications described in section 4.4.6. The charger also includes the following dry
contact alarms (as defined in the NFPA standard): AC failure, Charger failure and Low battery.

1.7 Functional Description
In the downlink, the signal from the Donor antenna is filtered to the 700MHz and 800MHz bands,
down converted, filtered according to the user defined (via GUI) channels, down converted and
amplified. The signals are then forwarded to the service antenna. In the uplink, the process is
reversed.
The maximum Analog Gain is 95dB, where Channel Gain between 0dB and 95dB is achieved by
reducing the Digital Gain from the System maximum Analog Gain; therefore, filtering and attenuation
is achieved through Digital Processing.
The block diagram showed in the figure below illustrates the overall functionality of the D-MBR PS
NFPA Signal Boosters and shows the operation flow in the downlink path and the uplink path.

3.6.1 Verifying Isolation between Donor and Service Antennas
Note the following:
• The isolation between the Donor and Service antennas is critical especially for high gain, outdoor
applications.
• For proper operation of the Signal Booster, it is recommended that the isolation between the
Donor and Service antennas be at least 15dB higher than the Signal Boosters set gain. (Lower
isolation can lead to high in-band ripple, oscillations and low signal quality.)
• Ensure proper vertical or horizontal distance separation between Donor and Service antennas
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.
3.6.2 Verifying the Link between the BTS and the Signal Booster
This test checks the signal strength from the BTS antenna to the Signal Booster.
Proceed as follows:
1. Using a Spectrum analyzer, measure the received signal from BTS at the Donor antenna port
near the Signal Booster.
2. Adjust the Donor antenna direction to receive the maximum signal strength.
3. Compare the received signal strength with the calculated signal strength from the design phase.
In case of discrepancy, check for one of the following:
• Antenna out of direction
• Antenna tuned to side lobe instead of main lobe
• Antenna connector or antenna cable faulty
• Line-of-sight problem (obstruction), etc.
4. Register the signal strength of the downlink channel for the system operation phase.

3.6.3 RF Cable Installation Guidelines
Note the following:
• For all coaxial connections to/from the Signal Booster - high performance, flexible, low loss 50
ohm coaxial communications cable.
• All cables shall be weather-resistant type.
• If the coaxial cables are NOT weather-resistant type: wrap the exterior coaxial cables with
insulation and holding tape (Type 3M Rubber splicing tape) for environmental protection and to
ensure longer lifetime.
• Cable length - determined by the Signal Booster installation plan. When calculating the cable
length, take into account excess cable slack so as not to limit the insertion paths.
3.6.4 Connecting Antennas
• Connect the Donor and Service antennas.
• Verify all RF connectors are tightened and the cables and antennas are secured.

7 MONITORING AND TROUBLESHOOTING
The D-MBR Booster provides the following indications of Booster failure:
• LED: on Booster front panel
• Booster level Alarms Log – displays a log of past and current generated alarms on a Booster level
• Band level Alarms screen – displays currently active band-level alarms
The following sections provide a description of the troubleshooting procedures according to the
Booster LED indicators and the Web Alarms.
7.1 LED Troubleshooting
Two status LEDs are located on the Booster panel – one for the Uplink and one for the Downlink.
The LEDs provides the following information:
Color Description Corrective Action
Green Normal (UL or DL) operation -
Red Power failure (in UL or DL) Corrective action: Turn off the Booster (this action
causes a reset of the function), and turn it on
anew. If the fault resumes, replace the unit.
Blinking
Orange/red Mute - either user- or
system-initiated.
(System initiated mute may
be due to isolation problem
or temperature).
Check gain of the booster
, if gain is minimum,
then it is an isolation problem -
> improve
isolation.
Turn OFF the Booster (resets the function), and
turn it ON again. If the fault resumes, replace the
unit.

7.4 Band-Level Alarms and Troubleshooting
The Alarms tab displays any alarms generated by the bands. The tab is common to both bands.
To display the Band Level Alarms tab
From the left pane, select the 700-800 item and choose the Alarms tab. The relevant alarms are
displayed.
When at fault, each generated alarm is displayed according to the factory set values for that alarm,
as Minor (yellow), Major (orange) or Critical (red).
NOTE: The alarm settings can be modified via the Alarms Configuration tab.
See the following page for alarm descriptions.
NOTE: Use the ACK ALL button to reset ALL displayed alarms.
Alarm Fault and most probable cause and Recommendation
System Mute Description. Generates an alarm when Booster amplification is
automatically
muted.
Possible causes: Temperature failure, Synthesizer failure,
Hardware failure, High RSSI power DL/UL when the shutdown mechanize is
on.
Recommended action: Check the LED and other alarm from the Booster.
Contact Cobham Wireless Support
User Mute Description: Manual shutdown performed by operator from the Web GUI.
Recommended action: Review unit’s log
Built In Test Possible causes: Hardware failure, Circuitry failure, Software failure
Recommended action: Contact Cobham Wireless Support
Temperature Description: Booster
temperature is exceedingly high due to excessive
external heat.
Recommended action: Check the Booster case for external causes (sun,
hot environment, air flow is blocked). Eliminate the reason for excessive
heat.

Alarm Fault and most probable cause and Recommendation
Donor Power
Too Low Description: Signal from the Donor antenna (DL) is too low - relatively to
the desired output signal configured by the user.
Recommended action:
Check the Donor/Base connections and antenna position. Check the signal
level of the Donor/Base antenna.
If the alarm is still raised, then you can raise, the value of the DL Output
Threshold Delta[dBm] as needed
.
(PAmp) Current Description: Power Amplifier current is not within limits (too high or too
low). If the Mute option is enabled, then this is not a fault since it indicates
low Power Amplifier current caused by the mute.
Recommended action: Check the LEDs status in the Booster and Contact
Cobham Wireless service support.
RSSI Description: Generates an alarm when a high
donor
input signal causes
system gain reduction
VSWR Description: This alarm is triggered when the return loss of the Downlink or
Uplink antenna or cable connection exceed the allowed limit.
This alarm provides an indication of the status of the cable/antenna
connected to the antenna. If a cable/antenna is defective, the VSWR is
decreased and the alarm is triggered.
Recommended action: Check the cable.
