Chapter 1. Introduction

1.1 About Celletra’s Cellular RF Repeaters

Celletra’s Cellular CDMA RF Repeaters provide Up-link (UL) and Down-link

(DL) cell coverage extension. They serve as a sophisticated wireless bi-

directional boosters, sensing and re-amplifying the RF cellular transmission in

DL (from the donor base-station to the mobile users), and in UL (from the

mobile-users to the donor base-station), simultaneously. Coverage extension

results in increasing traffic through the donor base station, thus improving

utilization of the Base Transceiver Station (BTS) resources.

Optimization of this network involves -above all- coverage and interference

control. Repeaters in the CDMA network are therefore interactive with the

donor cell and the neighbouring cells, and require flexible tuning and control.

Their effectiveness depends highly on these and other features.

Overall Unique Advantages

The Celletra Repeater product line shares unique features for exceptional

coverage, low impact on the cell, high controllability, and low maintenance

cost. The repeater system guarantees low Noise Figure (NF), high power

efficiency, unique flexibility in installation, and high reliability.

CCMS software through the RS-232 communication port

NOTE: For antenna installation tools, refer to your antenna

installation guide.

2.2 Run Sweep Test

Before installing the Repeater, run a sweep test of all RF cables and record

the cables loss. Perform the sweep test using a Time-Domain Reflectometer

(TDR) or a Network Analyzer.

• Perform open/short tests on the donor and distribution RF cables.

• Record in Appendix D the following parameters for each RF cable:

o Insertion loss of the cable

o Return loss (VSWR)

• If you detect a fault in any of the cables, repair it and re-check until all the

cables are good.



2.3 Mount the Donor and Distribution Antennas

The donor and distribution antennas are supplied by the Customer. Perform

the following steps, described in detail in later sections:

• Mounting the antennas in their selected positions

• Connecting the cables

• Testing the isolation between the antennas.

2.3.1 Mount the Antennas

NOTE: Be sure to mount and align the donor and distribution

antennas according to the manufacturer’s instructions and the

location parameters that affect the radiation pattern.

To achieve the required isolation between the two antennas, mount them on

opposite walls of the same building

NOTE: If the site conditions do not allow for the required isolation

under the given conditions, isolation screens (not supplied by

Celletra) may be used to provide the necessary results.

2.3.2 Measure Donor BTS Power.

Refer to Figure 2-1.

1. Connect a Power Meter to the Donor Antenna jumper in order to verify that the

requested sector is relayed.

2. Tune the antenna azimuth and elevation for signal reception.

3. Fine-tune the donor antenna for the maximum signal strength and tighten the

azimuth and elevation adjustments.

4. Record the maximum RSSI level at the donor antenna port:

Figure 2-1: Donor BTS Power Measurement Setup

5. Tighten and secure all donor antenna screws according to the antenna vendor’s

instructions.

2.3.3 Align the Distribution Antenna

The distribution antenna alignment is done according to planned coverage

requirements.

2.3.4 Measure The Isolation Between Antennas

Use the cables from the previous section to perform the isolation test.

Connect a signal generator instead of the power meter and a spectrum

analyzer instead of the Repeater.

Note: Make sure that the power meter operates in Peak Mode!



Isolation= PSG - CLSG - CLSA - PSA

Where: Isolation = Isolation between the antennas in dB.

PSG = Signal generator output power [dBm].

CLSG = Signal generator cable loss [dB]

(positive value of loss).

CLSA = Spectrum analyzer cable loss [dB]

(positive value of loss).

PSA = Spectrum Analyzer power reading [dBm].

NOTE: Correct isolation between the antennas ensures the Repeater

will work with the required gain without going into oscillations. If the

isolation is not sufficient, it will be necessary to reduce the Repeater

gain – affecting the Repeater coverage area.

2.4 Mount the Repeater

2.4.1 Precautions

CAUTION

The Repeater is an electrical equipment and should be

treated accordingly.

CAUTIONS

• Always shut down AC supply to the Repeater before

handling, replacing, or removing the unit from the

2.4.2 Repeater Unit Installation - General Instructions

• See detailed dimensions of the mounting hardware in Appendix C.



• RF coaxial cables connecting the Repeater:

• Type: low loss type

• Diameter: 1/2” or 7/8"

• Length: The cables should be as short as possible. Cable length

should not exceed 100m.

2.4.3 Sealing and Weatherproofing

Sealing and weatherproofing RF connectors is of prime importance to assure

good electrical contact for long term service and prevent passive RF inter-

modulation effects. Thus, special care should be taken with the RF connectors

sealing and weatherproofing.

For sealing instructions, refer, for example, to Andrews weatherproofing

recommendations with 3MTM Cold ShrinkTM Weatherproofing Kit, or an

equivalent sealing method.

CAUTION

Improper sealing can cause damage not covered by the

Celletra warranty.

From this point, the following functions are accessed by pressing the Right or

Left keys:

Gain <> Frequency <> Lock <> Alarms <> PA <> ALC <> Donor Pin Level

Pressing Enter when one of the above appears leads to its sub-menu.

Again, the functions of the sub-menus are accessed by pressing the Right or

Left keys.

When changing the frequency, each keystroke advances the frequency

groups a<>a1<>b<>c, and the display shows the respective channels

numbers.

Changing the values of these functions is done by pressing “Enter”, then the

Up or Down keys and “Enter” again, to confirm the changed value.

In addition, there is a graphical bar display of the Donor Pin level. One star is

the minimum (-75 dBm), 8 stars are the maximum (-30 dBm). The three digits

at the end are the power in dBm.

In order to exit the system, return to Lock in the menu and press “Enter”.

Notes:

The first pressed key will turn on the backlight, which will turn off within 10

seconds if no other key is pressed.

The system reverts to Lock state after 10 minutes of inactivity.

The system has only one security level of “Administrator” when using the

keypad and LCD. This level enables monitoring and changing parameters.

3.9 Repeater System setup instructions

Note that all power measurements should be made in Peak Mode!

3.9.1 ALC setting

Set the DL ALC to 28 dBm.

Set the UL ALC to 20 dBm.



3.9.2 Repeater DL Gain Setting

Isolation between the donor antenna and the sector distribution antenna

should exceed the overall Repeater gain by at least 10db.

G max =Isolation-10dB

The reason for this limit is avoid operation near oscillations of the Repeater. It

s on the isolation between the donor and the distribution antennas.

The required DL gain calculation is based on not exceeding 30 dBm output at

full traffic in all channels within the bandpass of the repeater. The DL gain can

be set within a range of 40 to 80dB as long as the gain does not exceed the

G max defined above.

CAUTION

Do not set excessive gain in the DL, otherwise, the Repeater

may enter the ALC state and the Power Control loop.

The gain set-up is done at night, when traffic is nil and only the BCCH is on

air. Leave a margin, related to the number of channels, for peak time

operation

If the repeater is approaching ALC during peak time, reduce the Gain

respectively.

NOTE: If reduced coverage is required, reduce the gains

accordingly.

3.9.3 Repeater UL Gain Setting

Set the Repeater UL gain value to the same value as the DL. This will make

the received signal at the base station somewhat higher than the noise floor. It

will be optimized at a later stage.



3.9.4 Repeater UL Optimization

1. Drive with a MS to the outskirts of the Repeater coverage area, and

observe the Mobile Tx Power (in test mode). Alternatively, walk indoors to

the worst-case locations.

2. Operate the CCMS software to remotely control the UL gain.

3. If the Mobile Tx Power reaches its maximum power, increase the UL gain

in 1dB steps until the Mobile Tx Power drops by 2dB below its maximum

value.

4. Do not, in any case, set the gain to a higher value than that set in this

Section.

3.10 Noise Rise Check

After completion of the optimization process, verify that the noise at the UL

channel at the BTS does not rise more than 1-2dB due to the Repeater

installation.

In case of noise rise greater than 2dB, decrease UL gain until reaching the

desired noise-rise.



Yes

Chapter 4. In Service Monitoring

This chapter explains how to use the CCMS software to setup and maintain the

Repeater system.

4.1 Launch Local CCMS

NOTE: This section is for local RS-232 connections only.

Double-click the CCMS icon on the desktop. The opening screen will open ,

showing the CCMS

Version:

4.2 Launch CCMS Via Modem (Optional)

Choose the modem type (instead of RS232) in the following screen



Figure 4-3

Key-in the modem phone number in the following screen:

Figure 4-4

Click Apply.

Main screen appears, as shown in Figure 4-6: Local Launch- Main Screen

4.3 Access the System

When you click the CCMS icon on the desktop, you enter CCMS with user authorization. To

change from the user authorization level:

Click on the security tab

From the Password menu, select Enter Password. The following dialog appears showing the

current authorization level.



Figure 4-5: Password Entry

Enter the Password corresponding to the authorization level you require.

Click OK.

NOTE: All authorization levels revert to User level after five minutes of

inactivity.

To change from a higher authorization level to user level, select Low Level from the

Password menu.

4.4 System Monitoring

The power screen monitors the Repeater gain and power on each of the links (UL

and DL).

NOTE: This screen defines also the setup parameters of the Repeater unit.

Figure 4-6: Main (Power) Screen



If the actual gain differs from the set gain by more than 1dB, the ALC has been

activated. Lower the gain by the value of the difference between them.
