PRODUCT DESCRIPTION AND USER’S MANUAL
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 ERP of type A signal boosters should not exceed 5W, this is equivalent to 8.2W EIRP.
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) = 39.1 – (33dBm - # of antennas in dB – cable losses in dB).
For example:
Equation (2) - Max DONOR antenna gain
Max DONOR antenna gain (dBi) = 39.1 – (27dB - cable losses in dB).
For example:
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 ERP 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 3302 signal booster has a noise level of -55 dBm in 10 kHz measurement at 1 MHz spectrum outside the passband of the signal booster and an in-band noise level at around ­50 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:
-55 dBm + Service Antenna gain – Antenna splitter losses in dBi – cable loss in dB
© Axell Wireless Ltd DOC PN 0034B-UM REV. 2.1 V
AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL
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) = -55+2-11 -11=-75 dBm The inband input noise to the antenna should be -50+2 -11-11= -70dBm
NOTE: In this example there is no need to add an external band pass filter to attenuate 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. All Axell Wireless repeaters include high selectivity duplexers and filters to attenuate the out of band noise. Should additional filtering be required, we have a comprehensive range of interference filters which can be supplied upon request.
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.
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.
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 58cm between the antenna and your body,
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 58cm entre l’antenne et le corps de l’utilisateur.

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 can either be installed indoors or outdoors. When installed outdoors - wet conditions increase the potential for receiving an electric shock when installing or using electrically powered equipment. 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, (especially at UHF frequencies) 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 50Ω, and that of free space at
377Ω, 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! 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. For FCC compliance, the Maximum Channel output must be <5 watts.
Warning: Antenna
Installation
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.
Installation of an antenna must comply with the FCC RF exposure requirements.
The antenna used for this transmitter must be mounted on outdoor or indoor permanent structures. The maximum antenna gain for indoor operation is 2.2 dBi. In indoor applications the antenna must be installed at a minimum separation distance of 58 cm from all nearby persons.

2.3 RF Cabling Requirements
For all coaxial connections to/from the Repeater - high performance, flexible, low loss
50Ω 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.
Make sure that cable and connector are compatible. Using cables and connectors from
the same manufacturer is helpful.
All connectors must be clean and dry Waterproof all outdoor connections using silicone, vulcanizable tape or other suitable
substance as moisture and dust can impair RF characteristics.
Make sure enough room has been allocated for the bending radius of the cable. RF
cables must not be kinked, cut or damaged in any way
Connect the RF cable to the antenna tightly but without damaging threads Fasten cables tight to cable ladder or aluminum sheet For short length of feeder cables use ½ “, for longer feeder cables use 7/8”. Chose
thicker coax cables for lower attenuation. Minimize the length of the coax cables to reduce the attenuation
Use jumper cable for easy installation. The RF Coaxial cable can be substituted at each
end with a jumper cable.

PRODUCT DESCRIPTION AND USER’S MANUAL
3 Pre-Installation Requirements
3.1 Safety Guidelines
Before installing the Repeater, review the following safety information:
Follow all local safety regulations when installing the Repeater. Only qualified personnel are authorized to install and maintain the Repeater. Ground the Repeater with the grounding bolt located on the underside of the Repeater. Do not use the grounding bolt to connect external devices. Follow Electro-Static Discharge (ESD) precautions.
3.2 Required BTS Information
Required BTS Information
BTS channels BTS output power per channel BTS antenna gain BTS antenna height Distance from Repeater site to BTS
3.3 Selecting a Location
Select a location that will take into account the following criteria:
Relative location of Base Station Cooling and airflow Wall compatibility Access to the repeater for installation or maintenance
3.3.1 Relative Location of Base Station
The repeater site shall be located where the BTS signal strength is great enough to be recognized by the system. For example, a D-CSR 3302 (85dBm max gain) and signal strength of -70dBm at the pickup antenna, a gain in the pickup antenna of 10dBi, a repeater gain of 85dBm and a server antenna gain of 2dBi the resulting ERP would be 27dBm. Losses in cables and other elements would change these figures slightly.
Repeater location near enough to BTS for received signal to be of adequate strength Ideally the repeater’s donor antenna should have line of sight (LOS) contact with the
BTS antenna. If the signal strength is high enough, LOS may in some cases not be necessary.
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.
3.3.2 Cooling and Airflow
Install the Repeater in a shielded, ventilated, and easy-to-reach area. The Repeater is convection cooled so airflow and alternation should be possible. Verify that ambient temperature of the environment does not exceed 50C (122F)
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 itself. Do not block this air

Operating Temperature
The D-CSR repeaters are designed primarily for multi carrier purposes. If the repeater is run at full output power over a long period of time the convection cooling might not be enough. The repeater has a power management function implemented that will step down the power and if needed fully shut down the amplifier chains until temperature has reached normal values. In situations where a repeater will be run in such a manner extra cooling can be provided for instance by putting the repeater in a temperature controlled environment or via external fans.
PRODUCT DESCRIPTION AND USER’S MANUAL
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 shadow to minimize the overall sun loading. If sufficient shielding cannot be obtained, an additional sun shield should be mounted.
3.3.3 Wall Compatibility
Check the suitability of the wall on which the Repeater is to be mounted. The Repeater wall mount brackets assembly should be fixed to a solid wall (these
include brickwork, blockwork, and concrete.);
(Due to the weight of the Repeater, it is NOT recommended to fix to a hollow wall).
3.3.4 Access to the Repeater
Plan connection cable clearances - the Optical, RF and power connections located on
the underside of the Repeater will need at least 300mm vertical clearance below the Repeater to enable the connections to be made. The minimum bend radius for Optical and 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
Repeater 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 analyser.
Allow space around the repeater - 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. Allow an additional 50 cm of space in front of the Repeater when the door is fully open.
Monitoring repeater - install the Repeater close to the service area to monitor the
output power.
