### **How It Works**

  

![how 3G mobile signal booster 4G LTE booster mobile signal amplifier Three mobile signal booster Vodafone signal booster Eir mobile booster eMobile signal booster UK mobile signal solutions 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 signal booster 4G LTE booster mobile signal amplifier Three mobile signal booster Vodafone signal booster Eir mobile booster eMobile signal booster UK mobile signal solutions 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 signal booster?  
    A: A mobile signal booster is a device that helps improve the strength of your mobile phone signal. It takes weak signals from outside, amplifies them, and sends them inside your home or office. This means you can make calls and use the internet more easily, even in areas where the signal is usually weak.
2.  Q: How does the 3G & 4G LTE mobile signal booster work?  
    A: The 3G & 4G LTE mobile signal booster works by receiving weak signals from nearby cell towers. It then boosts these signals and broadcasts them inside your space. This helps you get better call quality and faster internet speeds, making it easier to stay connected.
3.  Q: Who can benefit from using a mobile signal booster?  
    A: Anyone who struggles with poor mobile signal can benefit from a mobile signal booster. This includes people living in rural areas, those in buildings with thick walls, or anyone who frequently experiences dropped calls or slow internet. It's especially useful for families or businesses with multiple users.
4.  Q: Is the installation of the mobile signal booster difficult?  
    A: No, installing a mobile signal booster is generally straightforward. Most kits come with clear instructions. You just need to place the outdoor antenna where it can receive a good signal, connect it to the booster, and set up the indoor antenna. If you follow the steps, you should have it up and running in no time!
5.  Q: Can I use the booster with any mobile network?  
    A: Yes, the 3G & 4G LTE mobile signal booster is compatible with multiple mobile networks, including Three, Vodafone, and Eir Mobile. It works on both 800MHz and 2100MHz frequencies, which are commonly used by these networks in Ireland.
6.  Q: What is the coverage area of this booster?  
    A: This mobile signal booster can cover an area of up to 250 square meters. This makes it suitable for medium-sized homes, cafes, restaurants, and small offices. If you need to cover a larger area, you might consider adding more antennas.
7.  Q: Will the booster improve my internet speed?  
    A: Yes, using a mobile signal booster can significantly improve your internet speed. By amplifying the signal, it allows for faster uploads and downloads, making activities like streaming videos or video calls much smoother.
8.  Q: What should I do if I have no signal outside?  
    A: A mobile signal booster needs some signal from outside to work. If you have no signal at all outside, the booster won't be able to help. You might want to check with your mobile provider to see if there are any coverage issues in your area.
9.  Q: Are there any additional accessories I might need?  
    A: Depending on your specific situation, you might want to consider additional accessories like longer cables or extra antennas for better coverage. If you have a particularly large area to cover, these can help ensure that everyone gets a strong signal.
10.  Q: Is it safe to use a mobile signal booster?  
     A: Yes, mobile signal boosters are safe to use. They comply with regulations set by telecommunications authorities. They do not emit harmful radiation and are designed to enhance your mobile signal without any negative effects on your health.
