AXELL D-MBR 3007-3008-PS NFPA REPEATER
PRODUCT DESCRIPTION AND USER’S MANUAL
Compliance with FCC
Note the following: This repeater can be operated as Part 90 Class B repeater.
FCC Part 90 Warning Statement
Note the following
The installation procedure must result in the signal booster complying with FCC
requirements 90.219(d). In order to meet FCC requirements 90.219(d), it may be
necessary for the installer to reduce the UL and/or DL output power for certain
installations.
WARNING: This is NOT a CONSUMER device. It is designed for installation by FCC
LICENCEES and QUALIFIED INSTALLERS. You must have an FCC LICENCE or
express consent of an FCC Licensee to operate this device.
This is a Class B signal booster. You MUST register Class B signal boosters (as defined
in 47 CFR 90.219) online at www.fcc.gov/signal-boosters/registration.
Unauthorized use may result in significant forfeiture penalties, including penalties in
excess of $100,000 for each continuing violation.
FCC Part 15
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may
cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.
One must be aware that FCC regulation mandate that this repeater is to be used only for
in-building applications and thus feed passive or active DAS (Distributed Antenna
Systems) accordingly.
FCC RF Exposure Limits
This unit complies with FCC RF exposure limits for an uncontrolled environment. This
equipment can only be installed in in-building applications, driving passive or active DAS
systems. All antennas must be operated at a minimum distance of 35 cm between the
radiator and any person’s body.
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 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) = 37dBm[EIRP] – (33dbi – 10log(N)(dB) – cable loss in dB).
For example:
No. of Antennas Cable Losses Max Allowed Antenna Gain
4 2 37 - (33+6-2) = 0 dBd
1 2 37- (33+0-2) = 6 dBd
10 2 37- (33+10-2) = -2dBd
Note :0dBd = 2.15dBi
Equation (2) - Max DONOR antenna gain
Max DONOR antenna gain (dBi) = 37 – (27dbi - cable losses in dbi).

PRODUCT DESCRIPTION AND USER’S MANUAL
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 3308 signal booster has a noise level of -43 dBm in 10 kHz measurement at 1 MHz
spectrum outside the passband of the signal booster and an in-band noise level at
around -37 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) = -43+2-11 -11=-63 dBm
The inband input noise to the antenna should be -37+2 -11-11= -57dbm
NOTE: In this example you may be required in general to add an external bandpass filter that would
attenuate by additional 7 dB 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.
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 of 35 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 3.5dB, 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 30 cm entre l’antenne et le corps de
l’utilisateur.

D-MBR 3007-3008 PS NFPA (Digital Multi Band Repeater for Public Safety) is a highpower 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 3007-3008 PS NFPA supports all public safety technologies. For each filter, the
user can specify the start and stop frequencies with different options varying in time
delay and filter slope. This allows the engineer to trade off adjacent channel rejection
and time delay interference against a wider coverage area, permitting D-MBR 30073008 PS NFPA usage in applications where no other booster solution will work.
Every parameter of D-MBR 3007-3008 PS NFPA, including filter tuning and selection, can
be controlled via web based management. The patented Axell Wireless’ digital RF filter
enables simple initial setup for any channel plan and if necessary, allows some basic
reconfiguration due to re-banding.

1.3 NFPA Installation Architecture
To meet the National Fire Protection Association (NFPA) requirements, power to the
Repeater is provided via a UPS and the status of the UPS, Repeater and DAS system
(antennas) is monitored via alarm connections to the Fire Department Control Box.
NOTE: An alternative to the Fire Department Control Box connections is to connect the D-MBR PS
NFPA and UPS dry contact alarms to an Automatic Dialer. Axell Wireless recommends the AD-2000
Automatic Voice/Pager Dialer System.
The alarms are connected as follows:
• From the UPS - the power indicator alarms are connected directly to the Fire
Department Control Box.
• From the Repeater – the Repeater status and antenna status alarms are connected
The Repeater’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 Repeater gain adjustment. Combined with advanced control algorithms, SALC is capable of learning the traffic load characteristics and adjusting the Repeater RF
Gain to the desired value. Smart-ALC effectively reduces isolation problems.
NOTE: To reset the Repeater to its highest set gain value, disconnect the Repeater power cable for
several seconds and re-connect.
