AXELL DIGIMINI- AMERICAS REPEATER

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.

• 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.

• The Repeater is convection cooled so airflow and alternation should be possible.

• Follow Electro-Static Discharge (ESD) precautions.

• Install the Repeater close to the service area to monitor the output power.

• Use low loss cables to connect the antennas to the Repeater.

2.3.4 RF Cable Installation Guidelines

Required:

• 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.

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

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

To connect the antennas to the Repeater

NOTE: If the coaxial cables are NOT weather-resistant type, wrap the exterior coaxial cables with

insulation and holding tape (Type 3M Rubber splicing tape) for environmental protection and to

ensure longer lifetime.

1. Install the antenna cables along their path to the Repeater, and connect them to the Antennas.

NOTE: Be sure to use low loss cables.

2. Connect the Donor antenna to the Repeater BASE port. (Donor antenna specifications and

installation criteria are described in section 2.1).

3. Connect the Service antenna to the Repeater MOBILE port. (Mobile antenna specifications and

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-band 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).

The information can be viewed via the Band Info tab (described on the following page).

• 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. 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.

Fault and most probable cause and Recommendation

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.

RSSI

Fault in the DL or UL path

Most probable cause: caused by a excessively high input signal.

It is recommended to check the LEDs in the Repeater
