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.
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.

PRODUCT DESCRIPTION AND USER’S MANUAL

1 Introduction
Axell Wireless DIGImini (digital mini) is a scalable in-building mini-repeater with advanced digital
filtering capabilities. Each repeater supports two bands where two repeaters can be easily cascaded
into a compact assembly to provide tri-band and quad-band solutions.
For each band, the user can configure up to six non-contiguous sub-bands, where the gain and power
of each of the sub-bands can be individually defined. The Repeater provides highly accurate out-of-
band-rejection and simple, GUI based procedures for adjusting the pass band according to the
relevant frequency spectrums.
DIGImini includes the SmartALC power control algorithm that automatically optimizes the gain
setting by learning the actual range of RSSI levels over a user-specified period of time. The
SmartALC algorithm prevents oscillations, reduces the amount of isolation required by the system
and optimizes the system to minimize noise rise at the donor cell site.
A state-of-the-art Interference Mitigation and Oscillation Prevention (IMOP) is used to measure the
isolation between the antennas and gain is reduced immediately to prevent oscillation. Local Web
based management is available via an RJ45 connection.
Optional, complete, remote Web-based management via a GPRS/CDMA modem provided by the
DIGImini Control Unit (DMCU). The DMCU is ordered separately, where a single DMCU can
support a single DIGImini or two cascaded units.

DIGImini can be installed in two configurations: procedures:
• Single DIGImini unit – details in Chapter 3.
• Quad-band assembly consisting of two DIGImini units – details in Chapter 4
1.4 Smart-ALC Function
The Smart Automatic Level Control (Smart-ALC) is an innovative algorithm for automatic repeater
gain adjustment per sub-band.
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 eliminates the need to perform initial settings for maximal traffic load conditions and on-
site gain adjustments.
Smart-ALC maintains the Uplink/Downlink gain balance for system transparency. In addition, Smart-
ALC prevents oscillations that may occur due to insufficient isolation while maintaining the gain in a
linear range operation by adjusting the repeater paths’ gain accordingly.
IMOP (Isolation Measurement and Oscillation Prevention) algorithm effectively reduces oscillation
problems.
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.

3.1.5 Before Connecting the Antennas or Power
Before connecting the antennas or power perform the following procedures described in this section:
• Verify isolation between the donor and mobile antennas
• Verify link between the BTS and the Repeater
3.1.5.1 Verifying Antenna Isolation between Donor and Mobile Antennas
The isolation between the Base/Donor and Mobile/Service antennas is critical. Lower isolation
can lead to high in-band ripple, oscillations and low signal quality.
The isolation between the Base/Donor and Mobile/Service antennas is critical especially for high
gain, outdoor applications.
• For proper operation of the Repeater, it is recommended that the isolation between the Donor and
Service antennas be at least 10dB higher than the Repeaters set gain.
• Insure proper vertical or horizontal distance separation between Donor and Service antennas
NOTE: Lower isolation can lead to high in-band ripple, oscillations and low signal quality.
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.
3.1.5.2 Verifying Link between the BTS and the Repeater
WARNING!
PERFORM THIS PROCEDURE BEFORE CONNECTING THE ANTENNAS TO THE
REPEATER OR POWERING ON THE REPEATER. THE REPEATER SHOULD NOT
BE OPERATED PRIOR TO THE VERIFICATION OF THE OPERATING PARAMETER IN
ITS INSTALLATION ENVIRONMENT.
Before connecting the antennas or powering up the Repeater, verifying the Link
between the BTS and the Repeater
This test checks the signal strength from the BTS antenna to the Repeater.
AXELL DIGIMINI- AMERICAS REPEATER
PRODUCT DESCRIPTION AND USER’S MANUAL
© Axell Wireless Ltd Doc PN 4000003431 Rev. 3.8 25
Proceed as follows:
1. Using a Spectrum analyzer, measure the received signal from BTS at the Donor antenna port near
the Repeater.
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.
3.1.6 Antenna Connections
CAUTION! DO NOT CONNECT THE ANTENNA CABLES TO THE REPEATER
BEFORE VERIFYING THE INSTALLATION PARAMETERS.
CAUTION! DO NOT POWER-UP THE REPEATER WITHOUT EITHER THE
ANTENNAS BEING CONNECTED OR THE ANTENNA CONNECTIONS TERMINATED

5.2.3 Signal Levels and Channel Configuration
This section provides a description of the RF Gain setting criteria (set via the Controls and Params
Pane), the criteria determining the number of available bands and a step-by-step procedure of the
signal level and channel configuration procedure.
5.2.4 RF Gain Setting Criteria
The RF Gain is set automatically by the Repeater’s SALC function. The function sets the optimum
gain without exceeding the isolation limit.
The gain range is up to 73dB for all bands and is set by default to its maximum value.
The gain will then be modified automatically to its optimum value by the SALC mechanism. This
mechanism performs gradual learning of traffic load characteristics and adjusts the Repeater RF Gain
accordingly. (See section 1.3 for more information on the SALC mechanism).

5.2.5 Bandwidth and the Number of Available Bands
Each repeater supports either one or two bands (single or dual-band). Up to Six sub-bands may be
defined per two bands per repeater (e.g. on a dual-band repeater supporting bands 850MHz and
1900MHz, 4 sub-bands may be set for the 850MHz band and 2 sub-bands for the 1900MHz band,
with a total sum of 6 sub-bands). The number of available sub-bands or channels depends on the
technology and selected bandwidth as detailed below (note that some bandwidths (e.g. 15 or 20MHz
at 700/1900 MHz GSM) take up two channel resources).

repeater functionality.
• Temperature - Displays Repeater ambient temperature.
• DL Output Threshold Delta (dB) - the delta from the set Composite Output Power, below
which the alarm 'Donor power is too low' is activated.
For example, if the DL Output Threshold value is set to 8dB, when the Measured Composite
DL output power is 8dB less than the set Composite Output Power, an alarm is generated.
• Meas. Composite DL Output Power – displays the currently measured output signal level.
4. To configure each sub-band:
• Checkmark Enable. The configuration parameters in that row will be available.
• In the Downlink area, set the Start and Stop DL Frequency (MHz). (The Uplink Start and
Stop frequencies will be automatically allocated.)
The defined BW will be displayed in the BW KHz column (to the left of the Start Frequency).
• Set the (Downlink) Max Gain as follows: by default, the MAX Gain (DL) parameter is set to
its highest level (73dB). Change the Channel Max Gain (DL) according to the
measured/calculated input power and isolation measurements.
• The recommended Maximum Gain setting is approximately 15 dB less than the isolation
between the service and donor antennas.
5. If the site NOISE LEVEL is high enough to cause interference, adjust the noise level as follows:
• Adjust the Gain Delta parameter – this sets the delta between the uplink and downlink gain
(so the uplink gain is relatively lower than the downlink gain.
• Click Send.
• Repeat the procedure until the desired coverage is achieved.
6. More information on parameters for the selected sub-band:
• DL Set Ch. Max. Gain Sets the power for the antennas. The value is about 15 dB less than
the isolation between the donor antenna and the mobile antenna.
The Value defined in the DL path is reflected in the UL path, however to define
different UL and DL path values the Gain Delta parameter is used and its defined value
is added to the UL value.
• DL Measured RSSI - measured DL signal.
• DL Measured Ch. Gain - measured DL Gain (dB) for the selected sub-band.
• DL Measured Ch. Power - measured Power (dBm) for the selected sub-band.
• UL Gain Δ - used for noise control. Sets the difference between UL and DL gain.
• UL Measured Ch. Gain - measured UL Gain (dB) for the selected sub-band.
