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 42 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 42 cm entre
l’antenne et le corps de l’utilisateur.

1 INTRODUCTION
This manual describes the installation and setup procedures for Cobham Wireless SMR 700 800 high power,
Class A digital, public safety signal boosters.
All booster models relevant to this manual operate in the same manner will be referred to as the ‘booster’,
where any differences in the software configuration procedure or parameters will be addressed in the
relevant section.
It features up to 24 DSP based, software-controlled, variable bandwidth filters that are user-programmable
across the 700 and 800 MHz bands. All public safety technologies are supported.
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 configuration parameter, 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.
NOTE: Optionally, 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.

1.3 Architecture
To meet the National Fire Protection Association (NFPA) requirements, power to the Signal booster is
provided via an uninterrupted power source. This can either be a UPS or (if a UPS is not available), an AC
Feeder and Battery Charger (purchased separately).
The booster and its power source (UPS or Battery Charger), each provide dry-contact alarms towards the
Fire Department Control Box. (The Battery Charger alarms are described in the dedicated manual. In case of
UPS, refer to the manufacturer’s instructions).
The booster supports the following alarms:
• Two dry-contact alarms
• One external alarm from the Battery Charger or UPS
Alarm connections to the Fire Department Control Box are used to monitor the status of the uninterrupted
power source, Signal Booster and DAS system (antennas). The Alarm conditions are described in section 6.4
and section 3.4.3.3.
NOTE: As an alternative to the Fire Department Control Box connections, the booster and UPS or Charger
dry contact alarms can be connected to an Automatic Dialer. The AD-2000 Automatic Voice/Pager Dialer
System is recommended.

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 Battery Charger installation instructions are provided in a dedicated manual.
For installations where UPS is not available, the AC Feeder and Battery Charger unit can be purchased (see
Appendix B for ordering information).
The charger is connected directly to the AC inlet and includes a circuit to charge external batteries. The
charger also includes the following dry contact alarms (as defined in the NFPA standard): AC failure, Charger
failure and Low battery.
NOTE: BATTERY LOW indication is when battery reaches 70% at current consumption of ~ C/25

2.2.2 Enabling Monitoring of Service Antennas
For both indoor and outdoor service antennas:
The Booster supports monitoring of DC Service antennas. This requires a DC path through the transmission
line (and lightning protector) to the Service antennas. If the LAST Service antenna doesn’t provide a DC
return path, install a 1dB attenuator as illustrated in Figure 2-1.
NOTE: It is required to install a
single
1dB attenuator on the last service antenna (or on
one
of the last
service antennas if a splitter is used). If used on an antenna installed outdoors, be sure provide suitable
weatherproofing over attenuator and connectors or fit inside building.

2.2.4.2 Vertical Separation Configuration
The Vertical Separation configuration is recommended in cases where the BTS is relatively far and the
service coverage area is relatively small.
In Vertical Separation configuration, the Donor antenna can be installed either above or below the Service
antenna on a COMMON tower. It is required to set the distance between them to achieve maximum
isolation.
The figures below illustrate the installations.

2.2.4.4 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.
2.3 Required BTS Information
Required BTS Information
• BTS channels
• BTS output power per channel
• BTS antenna gain
• BTS antenna height and distance from antenna site
2.4 Selecting the Booster Location
When selecting a location, verify the requirements described in this section are met.
2.4.1 Installation Location Criteria and Environment
Location criteria
• Application type – indoor or outdoor
• Distance from antenna site and BTS antenna height.
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.
• General surroundings and accessibility of location
• Mounting surface - Use a suitable mounting surface, such as a flat back rigid wall.
• Plan mount – according to overall dimensions of the unit enclosure.
• Plan connection cable clearances - the connections located on the underside of the unit will need at
least 300mm vertical clearance below the unit to enable the connections to be made. The minimum
bend radius for 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 unit 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 analyzer. Allow an additional 500mm of space in front of the unit when the door is fully
open.

• Allow for heat dispersion - 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.) Do not
block this air 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 shade to minimize the overall sun loading. If sufficient shielding cannot be
obtained, an additional sun shield should be mounted.
Figure 2-7: Example of a sun shield
2.4.2 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.
2.5 RF Cable Installation Guidelines
• 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.

6 MONITORING AND TROUBLESHOOTING
The Booster provides panel LEDs, external alarms connectors and two types of (WEB GUI) alarm screens
used for viewing status and for alerting and troubleshooting the causes of Booster faults or failure.
The following sections provide a description of the various alarms, a description of possible faults and
corrective actions. In addition, the relevant screens for viewing the alarms are described.
6.1 Booster Panel LEDs
Two status LEDs are located on the Booster panel:
• Upper LED - UL status for one or two bands
• Lower LED - DL status for one or two bands
Figure 6-1. UL and DL Status LEDs located on Underside Panel
The LEDs provide the following information on status and possible faults:
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.

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 mechanizm 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.
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.
