AXELL 3307D REPEATER

PRODUCT DESCRIPTION AND USER’S MANUAL

Axell 3307D is a 700 MHz band LTE technology selective indoor mid-repeater that simultaneously

supports the LTE lower and upper frequency range: Lower700MHz A,B,C and Upper 700MHz C.

The Repeater supports advanced digital filtering capabilities. Up to 8 or 12 (model dependent) LTE

non-contiguous sub-bands can be selected via simple intuitive GUI, where each sub-band is

independently tunable across the entire LTE band. The gain and output power can be set individually

in each of these sub-bands. This provides an optimal solution for operators that have non-contiguous

spectrum.

The repeater provides highly accurate out-of-band-rejection and simple, GUI based procedures for

adjusting the pass band according to the 700 MHz spectrum.

3307D 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

(wireless connection provided by an integrated modem). Local setup can be performed through a

connection to the Ethernet port using a cross-cable.

AXELL 3307D REPEATER

PRODUCT DESCRIPTION AND USER’S MANUAL

-A

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.

The repeater’s interfaces are located on the front panel. These include Ethernet port, Mobile and

Base antenna connections, Alarm I/O, LED indicators, and power connection.

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

3.8.1 Verifying Isolation between Donor and Mobile Antennas

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 12dB 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.

AXELL 3307D REPEATER

PRODUCT DESCRIPTION AND USER’S MANUAL

The following table provides a description of the displayed alarms.

Alarm

Fault, 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 unit temperature.

Most probable cause: Excessive heat.

Check the Repeater case for external causes (sun, hot environment, air flow

is blocked). Eliminate the reason for excessive heat

Donor Power Too

Low

Generates an alarm when the Pre Amplifier current exceeds the allowed

limits

Fault in the DL or UL path.

Most probable cause: Downlink (Uplink) power amplifier module outputs a

low current.

Check the LEDs in the Repeater

PAmp Current

Generates an alarm when the Power exceeds the allowed limits.

Fault in the DL or UL path.

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.

PRODUCT DESCRIPTION AND USER’S MANUAL

The 3307D Repeater Power LED on its front panel (see 1.4) can be used for troubleshooting. The

following table provides a description of the DL and Power LED troubleshooting procedures.

LED Color Status, Probable Cause and Recommendation

Service Green Normal operation

Blinking - DL power below threshold---

Red Steady - Major error. Replace the Repeater.

Blinking – service muted by user.

Orange Blinking - service initiating on power up or reset.

Steady – high DL/UL signal or VSWR. This may be due to

isolation problem or temperature. Check gain of

repeater. If gain is minimum, then it is likely an

isolation problem -> improve the isolation.

Reset the Repeater by turning if off and on again. If the

fault continues, replace the unit.
