PRODUCT DESCRIPTION AND USER’S MANUAL
Axell Wireless Ltd 1
1 Introduction
Axell’s Digital Multi-Band Repeater for USA (D-MBR-USA) is an in-building, band-selective
repeater with advanced digital filtering capabilities that operates in the LTE 700MHz (simultaneously
in upper and lower band), CELL 850MHz, AWS 1700MHz and PCS 1900MHz bands. It provides an
excellent single unit solution for multi-operators or for operators with a non-contiguous spectrum.
Up to eight or twelve (model dependent) non-contiguous sub-bands can be user configured for each
band, 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.
D-MBR-USA 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.
GUI based web management is supported through both Ethernet and remote wireless connections
provided by an integrated CDMA modem. Local setup can be performed through a connection to the
Ethernet port using a cross-cable.

1.3 Smart-ALC Function
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 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.

4.3 Signal Levels and Channel Configuration
This section provides a description of the RF Gain setting criteria (set via the Controls and Params
Pane) and a step-by-step procedure of the signal level and channel configuration procedure.
4.3.1 RF Gain Setting Criteria
The RF Gain is set automatically by the Repeater’s SALC function (section
0). The function sets the
optimum gain without exceeding the isolation limit.
The gain range is up to 80dB for all bands and is set by default to its maximum value of 80dB.
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
0 for more information on the SALC mechanism).
4.3.2 Adjusting the Signal Levels and Configuring Channels
The Control and Params (parameters) window is used to configure up to 8 channels for each band
and the RF parameters. This section describes each of the fields.
Up to 8 sub-bands referred to as filters can be defined, where each sub-band is individually defined
by setting the following:
• Bandwidth (start and stop frequency) - each sub-band can be set over specific bandwidths. For
example, LTE sub-channels can be defined over the full (upper and lower) LTE for the following
bandwidths: 1.4MHz, 3MHz, 5MHz, 10MHz or 15MHz
• Maximum power
• Maximum gain
• Gain delta
The defined sub-bands are displayed in the lower part of the screen for reference.
Refer to the Band Info tab for information on the relevant bandwidths for each frequency. If you
attempt to define a bandwidth (block) that is not appropriate for the selected frequency, the
appropriate notification will appear.
Note that the number of supported channels depends on the technology as indicated below.
Filter BW Technology Frequency bands Number of
FPGA Resources
2.5Mhz-20MHz
( in 2.5MHz steps)
CDMA 850/1700/1900 MHz 2
1.5,2.5,11Mhz CDMA 850MHz 2
1.4,3,5,10,15,20Mhz LTE 700/850/1700/1900 MHz 2
To adjust the signal levels and configure the channels
1. In the left pane (Topology Tree), select the band (LTE, CELL, etc.) whose sub-bands are to be
configured.
2. Click the Control and Params tab. The relevant window appears.
The window is divided into the following areas:
• System – overall parameters for the selected service.
• Filter definitions – used to define up to 8 sub-bands and their RF parameters.
• Sub-bands view – graphical display of defined sub-bands for the selected service.

3. In the System area:
• Verify that the RF Transmission Enable parameter is checked. (This parameter is
used to disable (and re-enable) RF transmission for the band.)
• Set the user defined maximum output signal level for this band by defining the Max
Composite DL Output Power according to your site requirements (click Send). (The
Measured Composite DL Output Power is displayed in the adjacent field.)
If the Max Composite DL Output Power composite output power exceeds the defined
value, the Smart ALC feature begins working.
• Set the Max Composite UL Output Power according to your site requirements.

Additional parameters (not required for initial setup) are:
•
Oscillation Prevention Enable - Enables oscillation detection mechanism that
maintains 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. Configure each required sub-band (Filter) as follows and then click Send:
• Check the Enable box to activate the sub-band. The configuration parameters in that
row will be available.
• Set the Start and Stop DL Frequency (MHz) in the corresponding fields. (The UL
frequencies are automatically defined according to the DL values).
The defined BW will be displayed in the BW KHz column (to the left of the Start
Frequency).
Be sure to choose Start/Stop values that provide the appropriate BW (i.e. for LTE
1.4MHz, 3MHz, 5MHz, 10MHz or 15MHz).
• Set the (Downlink) Max Gain as follows: by default, the MAX Gain (DL) parameter
is set to its highest level (82dB). 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. The defined sub-band will appear in the display in the appropriate area.
• 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 ∆ - 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.
7. Click Send (top window area option).

6 Monitoring and Troubleshooting
D-MBR-USA provides an automatic system shutdown and recovery mechanism that is activated
when certain alarms are active. In addition, the repeater provides three types of indications and
troubleshooting tools:
• Alarms screen in Web access application
• Alarms Log – used to view a record of past generated alarms
• Status LEDs on Dual-Band Repeater front panel
The following sections provide a description of the troubleshooting procedures according to the
Repeater LED indicators and the Web access Alarms.
6.1 Shutdown and Recovery Mechanism
The D-MBR-USA shutdown-recovery mechanism mutes the system in the event of specific
alarms generation and re-activates the signal after the alarms are shut off.
The following alarms cause the system to enter the shutdown mode:
• Uplink RSSI.
• Downlink RSSI.
• Detection of oscillation.
• Uplink high output power out of range.
• Downlink high output power out of range.
The system periodically samples the above alarms at 0.5 seconds intervals (by default). If an alarm is
active for nine sequential loops (e.g. 0.5 * 9 = 4.5 seconds), the system will 'shut down' by muting the
PAMP.
When the system is in “Shutdown” mode, the recovery function will periodically sample the alarms
every two hours (by default). If the relevant alarm is no longer active, the system will return to
normal operation mode and reactive the signal.
The sampling and timing mechanisms can be modified by a technician level user.
The shutdown mode can be turned off by the user and the system re-enabled in normal operation
mode by setting RF Transmission Enable to ON.

Alarm Fault and most probable cause and Recommendation
System Mute Generates an alarm when Repeater amplification is muted (automatically)
User Mute Repeater amplification is muted (manually) as a result of an operator action.
Built In Test Self test.
Temperature High temperature.
Most probable cause: Unit temperature becomes high.
Excessive heat.
Recommendation: Check the Repeater case for external causes (sun, hot
environment, air flow is blocked). Eliminate the reason for excessive heat
Donor Power Too

Alarm Fault and most probable cause and Recommendation
Most probable cause: Downlink (Uplink) power amplifier module outputs a
low current.
Recommendation: Check the LEDs in the Repeater
RSSI Fault in the DL or UL path
Most probable cause: caused by a excessively high input signal
Recommendation: Check the LEDs in the Repeater
VSWR
This alarm is triggered when the return loss of the Downlink antenna or
cable connection exceeds 3 dB (VSWR 6:1).
This alarm provides an indication of the status of the cable connected to
the antenna. If a cable is defective, the VSWR is decreased and the alarm
is triggered.
Reduced Gain by
IMOP
Shows when the IMOP mechanism was activated in order to respond to
detected oscillations.
GREEN – normal operation – no oscillations were detected.
RED – oscillations were detected and the system reduced gain in order to
eliminate the oscillations.
Check the Donor and Mobile antenna installations for isolation. After
isolation is within the required levels, the system will automatically
increase gain (since it will no longer affect oscillations and) and the LED
will turn GREEN.
Interferer Power
Exceeded
Indicates if there is any external interference at a level that may affect the
operation of the unit.
Green – low or no interference. Unit operation is not affected.
Red – high external interference that may affect the operation of the unit. It is
recommended to identify the source of the interference and distance the
source or the unit from each other.
