GSM signal Booster for GSM mobile signal ST900&AI mobile signal booster for car/Vehicle/Home Use Max coverage 300sqm

What is Mobile Phone Repeater?

A mobile phone repeater picks up mobile phone signals from the outdoor antenna, then process and amplified the signal and rebroadcast to indoor areas by the indoor antenna. Mobile phone repeater is designed to increase mobile phone signal strength to all mobile phones on all mobile phone carriers and providers. Mobile phone repeater could virtually eliminate dropped calls, stuck text messages and slow internet speed. Mobile phone repeater system is the one-time investment without extra fees or landline internet connection.

What is AI intelligent Repeater ?

All Intelligence repeater with Smart CPU software and ATT function : 

What is AI function? And what is the advantage?

AI means Artificial Intelligence

The booster is with CPU inside, it can control the gain more intelligence according to surroundings than AGC function.

The booster with AI is energy-effective. When there is no call, the booster will change to a “Stand-By” state, thus can save a lot power.

The boosters with AI function have ALA LED on it, and it can easily help to find out the problem when setting and running.

Smart CPU software have three function :

1.it can help you save power ,when there is no mobile using ,the repeater will auto-turn down the uplink signal ,help you save power ;

2.it can help you check out when your installation have problem , when your installation is wrong , the repeater  can check out and the ARL LED will be lighted and alarm .

3.it can pretect repeater when there is a thunder or there is a very stronger repeater come in suddenly , the repeater ARL will alarm and remind you to re-plug the repeater adaptor;

Features of ST Signal Repeater :

1.High-gain linear power amplifier. 

2.ALC and AGC function technology. 

3.Ultra-low noise receive amplifier. 

4.There is no interference to the base station, right after the opening of the original system and the base station without the need to adjust parameters. 

5.Stable and reliable electromagnetic compatibility design. 

6.The base station dose not cause an increase in background noise, but will not lead to a decline in the quality of the base station communications. 

7.With full-duplex communication mode. 

8.It explores an effective and reasonable method to dispel the heat.

Mobile Phone Signal Repeater Installation Steps

Step 1: Install the outdoor antenna in a suitable place

Step 2: Connect the outdoor antenna to the booster “outdoor” side by cable and connector

Step 3: Connect the indoor antenna to the booster “indoor” side by cable and connector

Step 4: Connect to the power

Notices:

1.Connect outdoor (BTS) port with outdoor antenna. Connect indoor ANT (MS) port with indoor antenna. Outdoor antenna is mounted at a higher position. Both antennas should be 10 meters far away at least from each other. 

2.Indoor and outdoor antennas must be separated by wall. 

3.If the signal is still weak after installation, please check whether or not the outdoor antenna is pointed to signal tower correctly or elsewhere with stronger signal and confirm that the signal strength achieved -70dBm. 

4.If no signal for a long time after installation, please check the device power adapter whether or not connected perfectly and connectors connect well. 

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

6.Packed the outdoor connector by waterproof glue, otherwise wet condition will reduce the signal cover area.
