Preface

This User Manual provides installation, configuration, operation and maintenance guidance of the

repeater. Specifications are also provided at the end of this User Manual in order to help users better

understand the repeater. Please read the manual thoroughly and follow the instructions outlined in this

manual to ensure a long life span and a trouble-free repeater unit.

Warranty

Lightning protection must be done for all outdoor antennas. Damage to power modules, as a result of

lightning is not covered by the warranty.

Switching on the AC or DC power prior to connection of antenna cables is considered as an incorrect

installation process and therefore faults arising thereafter are also not covered under the warranty.

This entire manual should be read and understood before operating or maintaining the repeater system.

We assume no liability for customer's failure to comply with the precautions mentioned. This warranty

will not cover such failures to comply.

Safety Information

Do not operate equipment in an explosive environment. Appropriate AC or DC power needs to be supplied

to the repeater. To avoid power supply spark, please perform the grounding connection of the equipment.

In order to avoid equipment damage or human injury by lightning, static electricity and other phenomenon

of leakage electricity, we suggest all products must do the electric-discharge of the electrical grounding in

setup process. Incorrect power settings can damage the repeater and may cause electrical related injury

to the user.

1. Introduction

1.1 Appearance of the Repeater

The 10~30dBm Series Repeater is compact in size and light in weight. Hence, the

installation of the Repeater is easy, simply just plug and play. With the control panel in

front of the repeater, the repeater status can be seen during installation.

1.2 General Installation Layout

Figure 2 Profile

For indoor application, a typical installation layout of the Repeater is shown in Figure 2.

The Yagi antenna is used as the donor antenna, and is connected to the repeater. Omni

and panel antennas are being used as the service antennas.

The donor antenna is placed outside of the building, while the repeater is placed inside the

building to extend radio coverage to the dead zones.

1.3 Advantages

◆Fast & easy Installation

The installation of a repeater is easy and simple. With its plug and play design,

installation simplicity, and operational user friendliness, these features appeal greatly to

many operators for the purpose of indoor coverage or for temporary coverage during

network optimization.

◆Smart Function

Compare to the worldwide repeater brand, the 10~30dBm series repeater has a smart

function which can be activated via the front panel. This function can prevent UL

interference and self-oscillation caused by insufficient isolation between donor and service

antennas, and also setup parameters to keep optimal condition automatically; the only

thing for users is just activating this function by front panel.

Notify that the users can’t adjust by manual setting when smart function is initiated.

◆Auto Level Control

The 25dB ALC is used to maintain steady output power even when the donor source

signal fluctuates. Also when the ALC is activated, the ISOLATION LED indicator would be

lighted in orange, which means the Isolation may not be enough. It also prevents UL

interference and self-oscillation from insufficient isolation between donor and service

antennas.

◆Antenna isolation testing

The 10~30dBm series product also has a repeater mounted antenna isolation

detection function. Equipment installation completed boot automatically after the onset

detection transceiver antenna isolation, if transceiver antenna isolation can not meet the

installation requirements, the device will automatically reduce the gain to guarantee the

equipment in normal working, not self-excitation vibration, guarantee not to interference

protection of base station, repeater itself. At the same time alarm exhibit of lanterns bright

red light alarm. Device LED gain display panel will display device is reduced after the

equipment current gain state, which has the advantages of convenient construction, but

also to protect the base station equipment, and does not generate interference.

2. Installation

2.1 Isolation

Isolation is an important concept for the repeater system, and it is one of the factors

that affect the location of the donor antenna and server antenna. In the repeater system,

the isolation must be enough, which means the donor antenna cannot be installed too

close to the repeater. But what is isolation? The isolation is the propagation loss between

the donor antenna and the service antenna which needs at least 15dB higher than the

gain value of the repeater. Non-compliance to this criterion would result in poor signal

quality or poor signal strength in the coverage area and the amplifier of the repeater may

also be damaged.

Isolation ≧Repeater Gain + 15 dB

2.1.1 Self-Oscillation Resistance

Self-oscillation is a phenomenon that would occur when the isolation for the repeater

system is not enough. In other words, insufficient isolation betweendonor and server antennas

would result in self-oscillation. Which means part of the signal that is being amplified by the

repeater radiates back towards the donor antenna and gotpicked up by the donor antenna and

went through the repeater amplification process again. Severe oscillation would result in poor

signal quality and even damage the repeater. Self-oscillation will deteriorate the signals inside

the coverage area and interfere towards the BTS.

2.1.2 The Isolation Value

The precise estimation of the isolation value can be obtained via a physical test

measurement. This test measurement is done at the actual environment where the donor

antenna and the server antenna are installed for a repeater system. The test

measurement procedures are as follows:

1. Connect the signal generator (SG) to the donor antenna and transmit a signal with a

frequency (For GSM900, uplink is 890~915MHz and downlink is 935~960MHz.

Choose frequency 920MHz to do the test. For DCS1800, uplink is 1710~1785MHz

and downlink is 1805~1880MHz. Choose frequency 1795MHz to do the test. For

WCDMA2100, system uplink is 1920~1980MHz and downlink is 2110~2170MHz.

Choose frequency 1995MHz to do the test. In simple words, choose the idle

frequency of the system to do the test) of certain power level from the SG.

2. Connect the spectrum analyzer (SA) to the service antenna and scan for the known

frequency (The frequency used by the signal generator). Mark the received power

level on the SA.

3. Subtract the power level received at the spectrum analyzer from the output power

(OP) level of the signal generator to obtain the isolation value.

Isolation (dB) = OP from the SG –Received Power on the SA

Transmit a strong OP from the SG is recommended (excess of 20dBm) for easy

recognition and detection by the SA.

2.2 Precautions and Preparation

1. Ensure the power applied to the repeater is within its working range. A separate

circuit breaker is recommended.

2. Ensure the donor antenna is installed at the location where signal from the donor

BTS (Node B) is good enough.

3. Ensure there’s sufficient isolation between the donor and server antenna.

4. The repeater is designed for indoor application. Ensure the location of the repeater

is dry and ventilative.

5. Ensure there are adequate resources to handle the weight of the repeater.

2.3 Donor Antenna Installation

The location of the donor antenna strongly influences the performance of the RxLev

(RSCP for 3G) and RxQuality (Ec/No) of the intended coverage area.

The donor antenna is usually installed outside of the building, pointing towards the donor

BTS (NodeB) for best reception of the receiving signal. When choosing the location for the

donor antenna, there are 3 criteria need to be met:

For 2G Systems

1. The Rxlev of the signal, at the input to the BTS port of the repeater is suggested to be

in the range of -55dBm to -70dBm

2. The RxQuality index ranging from 0 to 2 is required.
