1. PRODUCT INTRODUCTION

The GSM900 BAND SELECTIVE Pico Repeater provides an affordable solution to solve the indoor signal

coverage problems in GSM900 system due to signal fading and attenuation caused by architectureobstacles. And its easy installation and maintenance can help carrier get fast return.

The Pico-repeater is working as a relay between the BTS and mobiles. Pico Repeater is applied

specially in small area indoor DAS system. The base station signal is coupled and amplified by Pico

Repeater into in-building system. The amplified signals are transmitted by indoor antenna. Meanwhile

the indoor antenna receives the cell phone signal, and sends the signal to the base station as uplink.

This method can eliminate the signal dead spot, reject the interference, and provide the stable signal

communication for cell phone users. This Pico Repeater mainly solves the problem spot problem in

building.

Pico Repeater is a bi-directional amplifier that allows for the reception of signals, amplifies the signal

and re-transmits into areas where there is no or very low signal level coverage enabling mobile userto establish a call connection.

Pico Repeater can be deployed in indoor coverage. It is especially advantageous to use in 100-1000

sq.m, which is a very economical solution.

2. USAGE SCOPE

To expand signal coverage or fill signal blind area where signal is weak or unavailable.

residential house villas

basements Hotels

parking lots exhibition centers

border village

offices vessels

shopping malls tunnels

countryside mines

Clubs underground facilities

3. CHARACTERISTICS

AUTOMATIC LEVEL CONTROL FUNCTION

With the function of digital ALC, the dynamic gain adjustment range is more than 20dB. It ensures the

Pico Repeater works in linear status and provides the high reliability and stability.

SELF-OSCILLATION AUTOMATIC DETECTION FUNCTION

It has the function of self-oscillation automatic detection (It detects the isolation when boot time),

which detects the self-oscillation occurred by inadequate isolation between the donor antenna and

service antenna. The Pico Repeater can activate AGC to set the Pico Repeater gain when

self-oscillation occurred.

UPLINK/DOWNLINK GAIN ADJUSTMENT SYNCHRONIZATION UPLINK ANDDOWNLINK GAIN SETUP AUTOMATICALLY

After the system is powered up, the input power is detected automatically and then the output power

is adjusted. After the downlink gain is calculated by the system, the uplink gain can be adjusted

equivalently. This method can balance the system amplification. The both path gain is adjusted

relevantly. The system gain is less than the system path loss. So the Pico Repeater will not bring any

interference and noise into the system link. One base station can hook up more than one Pico

Repeater.

6. INSTALLATION INSTRUCTIONS

1) It supports wall mounting installation, follow the instructions below.

FIGURE 5 MOUNTING HOLE

1. First of all, choose a mounting position for the Pico Repeater in indoor environment. And

then align Pico Mounting hole on the wall and be marked

2. According to formerly marking on the wall to drill the holes, and inserted the rubber plug in

the holes.

3. Use screws fix the Picos mounting hole on the wall where Pico is going to be installed.

4. The BTS port on Pico Repeater is connected to the donor antenna, MS port is connected to

the service antenna.

5. System is supplied by AC100-240V power via connection of the external extension power

cable.

6. The system works properly under the condition of having enough system isolation.

7. With obstruction or no, it must ensure the distance of 5-30 m between the donor antenna

and service antenna.

THE LED INDICATORS

The indicators on the front panel could be lightened are listed in the table below

Indicator Status

Power Indicator

Green light indicates that mian power supply is normal.LED off

indicates the main power is off

Module IndicatorGreen light indicates that main power or battery is normal; LED

off indicates the main power and battery are off

Run IndicatorFlashing green light indicates normal, if the LED is OFF,it means

the MCU of control panel fails.

Modem IndicatorThe indicator lights green while SIM card is being

inserted,signal is being recieved and data cable is disconnected to local

test port at the same time, otherwise indicator is off

System Indicator

Green light indicates that the system is

selected and can be read and set

UL/DL Indicator

Green light indicates that the UL(DL) band is selected

and can be read and set

Smart Function Indicator When the LED indicator is off, the Smart Function is OFF; It is inManual mode

When the LED indicator is green,the Smart Function is ON

Alarm Indicator When the indicator is green , it is in normal status.When the indicator is red, it means the AGC function is active or Pico

Repeater Self-Oscillation is occurring.

Be noted that users cant adjustparameters by manual setting when smart function is

activated (Pico can save data for GSM900 when you adjust it manually).Repeater must not be

powered on before the donor antenna and service antenna are connected.
