-   External Signal Needed: The signal booster can only amplify signal but can't create signal. If there is no signal outside, it won't work, please make sure you get 1-2 bars signal outside.

### Custom your solution

#### **Expandable coverage by adding indoor antenna if the outside signal is strong.**

### **How It Works**

  

![how 3G mobile phone signal booster 4G LTE booster mobile signal booster indoor coverage mobile phone reception signal booster installation compatible with multiple users UK mobile boosters 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 3G mobile phone signal booster 4G LTE booster mobile signal booster indoor coverage mobile phone reception signal booster installation compatible with multiple users UK mobile boosters 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 quality of your phone signal in areas where it is weak. It captures weak signals from outside, boosts them, and then sends the stronger signal inside your home or office, allowing you to make calls and use data more effectively.
2.  Q: How does the 3G & 4G LTE Mobile Phone Signal Booster work?  
    A: The booster has three main steps: First, it receives the outside mobile signal through its antenna and sends it to the booster unit. Next, the booster amplifies this signal, making it much stronger. Finally, the enhanced signal is broadcasted inside your space, improving your call quality and data speed.
3.  Q: Who can use the 3G & 4G LTE Booster?  
    A: This booster can be used by anyone who struggles with weak phone signals inside their home or offices. It supports multiple users, so families or small businesses can all benefit from a better signal at the same time.
4.  Q: Does it work for all phone networks?  
    A: Yes, the 3G & 4G LTE Mobile Phone Signal Booster is designed to work with various mobile carriers. So, if you have a compatible device, you can enjoy improved signal coverage regardless of your service provider.
5.  Q:  
    A: How much area does the booster cover? The booster provides coverage up to 100 square meters, making it perfect for small apartments or offices. If you need to cover a larger area, you can consider additional antenna options for expanded coverage.
6.  Q: Is it difficult to install the booster?  
    A: Not at all! The installation is pretty straightforward. You just need to connect the outdoor antenna to the booster and place the indoor antenna where you want to improve the signal. The kit comes with clear instructions to guide you through.
7.  Q: What if there is no signal outside?  
    A: The booster needs at least a little signal from outside to work. If there is no signal at all, the booster won’t be able to improve your reception. You’ll need to find a spot where there is some signal, even if it’s weak.
8.  Q: Can the booster affect my phone's battery life?  
    A: Generally, using a signal booster can actually help your phone's battery life. When the signal is weak, your phone works harder to connect, draining the battery faster. With the booster, your phone has a stronger signal, which may help improve its battery performance.
9.  Q: How do I know if I need a stronger antenna?  
    A: If you notice that your phone still has a weak signal indoors after installing the booster, especially with only one or two bars of reception, upgrading to a stronger antenna can help you capture the signal better and improve your overall experience.
10.  Q: What are the benefits of using a signal booster?  
     A: Using a signal booster can lead to clearer voice calls, faster data speeds, and fewer dropped calls. It's especially beneficial if multiple people in your household are using phones at the same time. You’ll enjoy a better and more reliable connection!
