Doc. No.00060CDUM

Date: 17-Jan-16


Page | V



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. www.cobham.com/wireless

D-MBR 3707-3708 PS NFPA Class A Signal Booster


1 INTRODUCTION

D-MBR 3707-3708 PS NFPA (Digital Multi Band Repeater for Public Safety) is a Class A Digital Multi-

Channel Signal Booster (DCSB). It features an array of up to 12 DSP based, software-controlled, variable bandwidth filters (up to 75Khz) per band , 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 A - signal booster for SMR and public safety networks

• Supports APCO 25 phase 1 and 2 for public safety networks

• NFPA 72-2010, Chapter 24 and IFC 510.1 Compliant

• Support of 700MHz D block for LTE network

• Patented DSP filtering™ technology:

• Supports up to 12 independent filters per band

• User programmable bandwidth / frequency

• NEMA4 enclosure

• SALC-Smart ALC mechanism to protect the digital signal booster from oscillation and shutdown the signal booster when required

• Web based management, SNMP traps

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).

NOTE: The Power Feeder Battery Charger is described in Chapter - 4).

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).

As an alternative to the F ire Department Control Box connections, the D-MBR PS NFPA and UPS or

Charger dry contact alarms can be connected to an Automatic Dialer. The AD-2000 Automatic

Voice/Pager Dialer System is recommended.

If the AC power to the UPS fails, the required power is provided by the battery and the AC Power Fail alarm is activated.

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.

NOTE: BATTERY LOW indication is when battery reaches 70% at current consumption of ~ C/25

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.

2.2.3.4 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

WARNING!!

The signal booster must always be installed vertically with the connectors on the underside for protection (see 3.3.3.4). Horizontal installation on a bench for long time may cause damage to the signal booster due to over-heating.

The following criteria should be considered when selecting the Signal Booster installation site location:

• 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

• In outdoor applications it is recommended to install a cabinet or a shielding sunroof for further protection against weather wear.

• Use a suitable mounting surface, such as a flat back rigid wall. www.cobham.com/wireless

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.

3.3 Mounting the System

Note the following:

• The mounting procedure is identical for both Booster and Battery Charger (where relevant) installations.

• The mounting procedure is identical for both indoor and outdoor installations.

• The weight of the Booster requires that two people mount the unit on the wall.

• Washers are not supplied with the unit to be mounted.

• In addition to the bracket assembly, it is recommended to use additional fixings – an example is given in section 3.3.3.4.

3.3.1 Location Criteria

Location criteria

• Plan mount - check the actual fixing centers (see below) and overall dimensions of the unit enclosure. The unit is supplied with two wall mounting brackets; when the unit is mounted on these brackets adequate ventilation is provided between the unit and the wall to which it is fixed.

• 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.

• From the left pane, select 700-800 item and choose the Alarms Configuration tab.

• When activated due to a fault, the alarm is displayed in the selected color. The color corresponds to the alarm level.

• Each alarm can be set to one of the following levels: Minor (yellow), Major (orange) or Critical

(red).
