### **How It Works**

  

![how mobile signal booster Ireland mobile booster Three Vodafone Eir boost voice calls indoor signal coverage GSM signal amplifier mobile reception improvement 250m2 coverage work for home office](https://cdn.shopifycdn.net/s/files/1/0488/4129/3976/files/ProductPageHIWhomeoffice-2.webp?v=1650634397)

#### 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.

![how mobile signal booster Ireland mobile booster Three Vodafone Eir boost voice calls indoor signal coverage GSM signal amplifier mobile reception improvement 250m2 coverage work for home office](https://cdn.shopifycdn.net/s/files/1/0488/4129/3976/files/ProductPageboostedcoverage-2.webp?v=1650634397)

#### 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.
