2100mhz Mobile Signal Repeater ST-3G Max coverage 1000sqm 

A 3G repeater provides the ultimate solution in any area where cellular communications can not work well due to leak of signals.The repeater device features easy installation & operation, build-in indoor antenna and no interference. It could also improve indoor electromagnetism environments, protract cellular battery life and reduce radiation of cell phones.  A 3G signal booster is ideal for house, home, and office use.

The repeater system work like this :

1.The outdoor antenna collect the signal and transimit it to the repeater

2.The repeater amplify the signal tansimited and send it to the indoor antenna

3.The indoor antenna broadcast the signal and the mobile phone receive the amplified signal.

We deveioped a series of wide band repeater, sepcifically designed and suitable to send and cover signal to homes, offices, restaurant, shopping market , elevators and parking lots etc. 

ST Mobile Signal Booster Features:

1.ALC AGC ensure output level stable and adjustable continuously.

2.Increases indoor signal coverage-up to 1000 sqm.

3.Supports multiple users simultaneously.

4.LED indicate and judge to signal level of uplink and downlink. 

5.Decreases dropped or missed calls.

6.Full-Duplex Communication Mode.

7.Easy to set up – comes complete with everything you need.

8.Extends phone battery life (uses less power when signal is stronger).

9.CE authentication certificated.

Steps that describe the work of Repeater:

1)The outside antenna receives the signal from the nearest mobile base station.

2)The outside antenna sends the received signal to the installed Repeater through the coax cable. 

3)The Repeater accepts the low signal and amplified it.

4)The amplified signal goes to the inside antenna through the connection coax cable.

5)The inside antenna send the amplified good signal to your mobile phone.

Mobile Phone Signal Repeater Installation Steps

1.Mount the Outdoor Antenna. Choose a location for the Outdoor Antenna using your cell phone to determine the area of strongest signal. For example, on window or on roof.

2.Mount the Booster. Choose a place the Booster where you want to create a Cell Zone.

3.Use the coaxial cable to connect between the outdoor Antenna and the Booster.

4.Mount the indoor Antenna. Choose a place indoor Antenna where you need signal.

5.Use the coaxial cable to connect between the Booster and the indoor Antenna.

6.Connect the Booster to the provided power supply and plug into a power outlet.

Signal problem & installation technique supporting

1.If still weak signal receipt after installation, please check if outdoor antenna point to signal tower correctly or elsewhere has stronger signal and confirm signal strength achieve-70DBM.

2.If still have no signal after installation, please check our device power adapter whether connected perfectly? And connectors connect well.

3.If strength is not steady, please check if outdoor and indoor antenna is too close; please ensure outdoor antenna has distance of 10 meters at least, with a barrier and not in a same horizontal line.

4.Packed the outdoor connector by waterproof glue, otherwise wet reduce the signal cover area.
