PRODUCT DESCRIPTION AND USER’S MANUAL

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 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.

l'émetteur par

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.

AXELL DIGIMINI- AMERICAS REPEATER

PRODUCT DESCRIPTION AND USE R’S MANUAL

1 Introduction

Axell Wireless DIGImini (digital mini) is a scalable in-building mini-repeater with advanced digital filtering capabilities. E ach r epea ter suppo rt s two band s w here two repea te rs 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-ofband-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 onsite gain adjustments.

Smart-ALC maintains the Uplink/Downlink gain balance for system transparency. In addition, SmartALC 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.

easy access to the repeater for maintenance and on-site inspection.

• 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 Repeate r.

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 P ow e r

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 VERI FICATION OF THE OPERATING PARAMETER IN

ITS INSTALLAT ION 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.

PRODUCT DESCRIPTION AND USE R’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 VERIFYIN G T H E INSTALLATION PARAMETERS.

CAUTION! DO NOT POWER-UP THE REPEATER WITHOUT EITHER THE

ANTENNAS BEING CONNECTED OR T HE A NTE NNA CONNECTIONS TERMINATED WITH DUMMY LOADS.

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 cri ter ia are desc ribe d in sect ion

The RF Gain is set automatically by the Repeater’s SALC function. The function sets the optimum gain without exceeding the isola t ion limit.

The gain range is up to 73dB for a ll 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 Availa ble 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).

• 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.

• 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

6 DMCU Installation and Management

NOTE: In case of two cascaded DIGImini repeaters, a single DMCU serves both repeaters.

The DMCU is a separately ordered unit that provides various controls and monitoring functionality, including: Ethernet access, modem functionality (i.e GSM/GPRS, CDMA) and external alarms. A single unit can serve either a single Repeater or a Quad-band assembly comprising of two units.

The DMCU modem antenna is internal, where communication is established with the Repeater via the external Modem connector at the side of the Repeater.

The DMCU is mounted externally, adjacent to the Repeater, and connected to the Repeater (or to one of the Repeaters in case of a quad-band repeater assembly) via two cables: RS485 and SMA. The unit is powered by the Repeater – no power-supply is required.

This section describes the DMCU interfaces, installation procedure and management capabilities provided by the unit.
