### **How It Works**

  

![how 4G LTE mobile phone signal booster Orange Bouygues SFR signal booster for calls 100m2 coverage UK mobile booster enhance mobile signal improve call quality 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 phone signal booster Orange Bouygues SFR signal booster for calls 100m2 coverage UK mobile booster enhance mobile signal improve call quality 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.  Q: What is a mobile phone signal booster?  
    A: A mobile phone signal booster is a device that helps improve the strength of your mobile phone signal. It picks up weak signals from outside, amplifies them, and then sends the stronger signal inside your home or office. This way, you can enjoy better calls and faster internet!
2.  Q: How does the 4G LTE & Calls booster work?  
    A: The 4G LTE & Calls booster works in three simple steps. First, it uses an outdoor antenna to capture weak signals from a mobile tower. Then, the booster amplifies the signals and sends them through an indoor antenna, which makes the signal stronger inside your home. This helps you to have clearer phone calls and faster internet!
3.  Q: Is it easy to install the signal booster?  
    A: Yes! Installing the signal booster is quite easy. You just need to connect the outdoor and indoor antennas, find a good spot for them, and power it on. You don’t need any special tools or skills, and most people can do it themselves without difficulties.
4.  Q: How much area does this booster cover?  
    A: This particular booster can cover an area of up to 100 square meters. That makes it great for small apartments or offices. If you have a larger space and need even more coverage, you might want to look for other models that cover larger areas.
5.  Q: Which mobile networks does this booster work with?  
    A: The booster works well with multiple mobile networks in France, including Orange, Bouygues, and SFR. It boosts signals for both 4G and 2G networks, which means you can make clear voice calls and send text messages without interruption.
6.  Q: What do I do if there is no signal outside?  
    A: The signal booster can only amplify existing signals, so if there’s no signal outside, it won’t work. You need to have at least 1-2 bars of signal outside for the booster to be effective. Check the signal strength outside before purchasing.
7.  Q: Can I use the booster for multiple devices?  
    A: Yes, you can! The booster can support up to 10 devices at the same time. This is particularly useful for households with several family members who are all using their phones and tablets.
8.  Q: Will the booster make my battery last longer?  
    A: Yes, using a signal booster can help your phone's battery last longer. When your phone struggles to find a signal, it uses more battery power. With a good signal from the booster, your phone won’t have to work as hard, helping the battery to last longer!
9.  Q: Can I upgrade my booster later?  
    A: Absolutely! If you find that you need more coverage or better performance, you can upgrade the antennas or cables. There are options available to enhance your booster’s capabilities.
10.  Q: Do I need to worry about installing a lightning protector?  
     A: Installing a lightning surge protector is a good idea, especially if you live in an area prone to storms. It protects your booster from electrical surges caused by lightning strikes, making sure your system stays safe and functional.
