#### 1

**Receives signal**  
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster  

#### 2

**Boosts signal**  
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.  

#### 3

**Broadcasts signal**  
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.  
  

  

#### **Get stronger signal**

#### Normal Cell Coverage

Dropped calls and slow data are generally caused by three things: distance from a cell tower, building materials in your home or office, or obstruction from tall objects such as trees, topography, and buildings.

#### Signal Coverage with our booster

Signal boosters increase cell signal by collecting signals with a powerful antenna, delivering those signals to the booster, amplifying the cell signals so your devices receive them, and delivering your device's boosted signals back to the cell tower.

#### **Installation**

1.  Connect the indoor antenna to the MS port.
2.  Connect the outdoor antenna to the BS Port.
3.  Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna.
4.  Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station.
5.  Power on the booster and check the signal strength.
6.  Adjust the outdoor antenna until you get the best signal strength.

**IMPORTANT NOTE**:  
DO NOT POWER ON THE DEVICE UNTIL YOU HAVE COMPLETED THIS SETUP.

1.  What is a mobile signal booster? - A mobile signal booster is a special device that helps improve the signal strength for your mobile phone. It takes weak signals from outside, amplifies them, and then sends stronger signals indoors to improve your call quality and internet speed.
2.  How does the 4G LTE & 3G signal booster work? - This signal booster works by capturing the existing mobile signal from the outside, amplifying it, and then redistributing it inside your home or office. It helps eliminate dropped calls and slow internet by boosting the 4G LTE and 3G signals.
3.  Where can I install the signal booster? - You can install the signal booster in medium-sized areas like homes, cafes, restaurants, and offices. It works best in spaces up to 250 square meters.
4.  Do I need a strong signal outside for the booster to work? - Yes, the booster can only amplify an existing signal. If there's no signal outside, the booster won't be able to provide any coverage inside.
