### **How It Works**

  

![how 4G LTE Mobile Signal Booster UK Networks EE Vodafone O2 Indoor Coverage Improve Signal 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 4G LTE Mobile Signal Booster UK Networks EE Vodafone O2 Indoor Coverage Improve Signal 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.

1.  What is a Mobile Signal Booster? - A Mobile Signal Booster is a device that helps improve the signal strength for your mobile phone. It takes in weak signals from outside and amplifies them, so you can enjoy better calls and texts inside your home or office.
2.  How does it work? - The booster consists of three main parts: an external antenna that captures weak signals from outside, a base unit that amplifies those signals, and an internal antenna that spreads the boosted signal throughout your space. This allows for better reception inside.
3.  How much area does this booster cover? - This particular mobile signal booster can cover up to 100 square meters. This is perfect for small apartments or offices where you want to improve voice calls and text messaging.
4.  Do I need a good signal outside for it to work? - Yes, the mobile signal booster can only amplify existing signals. If there's no signal outside, the booster won't be able to help you. It's best to check the signal strength with your phone outside before buying.
5.  Can I install it myself? - Absolutely! The mobile signal booster comes with all necessary components for installation. You can set it up following the instructions, but it's recommended to do a 'loose' install first to find the best spot for your antennas.
6.  Is it compatible with all networks? - This booster is designed to work with several networks like A1, Three, and T-Mobile in Austria. It boosts the 900MHz frequency used for 2G services. Just make sure to check your network compatibility!
7.  What if I need longer cables? - If the standard 10-meter cables are not long enough for your setup, you have the option to upgrade to longer cables, such as 20 or 30 meters, so you can reach the best signal location.
8.  What happens if there’s a lightning storm? - It's important to protect your equipment during storms. You can add a Lightning Surge Protector to your installation to safeguard against high surge currents from lightning strikes.
9.  Can it boost internet speed? - This mobile signal booster primarily enhances voice calls and text messaging. It doesn't boost data speeds directly, but by improving your signal quality, you may notice an improvement in your internet connectivity as well.
10.  How do I check my signal frequency band? - You can check the frequency band by dialing \*3001#12345# on your iPhone and pressing call. Then select 'Serving Cell Info' to see the 'Freq Band Indicator'.
