#### 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.

#### 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 works by receiving weak signals from outside, amplifying them, and then broadcasting the stronger signal inside your home or office. This means you can make calls and use the internet more easily, even in areas where the signal is weak.
2.  Q: How does the 3G & 4G LTE booster work?  
    A: The 3G & 4G LTE booster works in three simple steps. First, it receives the mobile signal through an outdoor antenna. Then, it amplifies this signal inside the booster. Finally, it broadcasts the boosted signal through an indoor antenna, allowing your devices to connect more reliably to the mobile network.
3.  Q: Who can benefit from using this booster?  
    A: Anyone who struggles with poor mobile signal at home or in their business can benefit from this booster. It is especially useful for families with different mobile networks, as it supports multiple operators like EE, O2, Vodafone, and Three. Whether you are in a small cottage or a larger space, this booster can help improve your signal.
4.  Q: What areas can the booster cover?  
    A: The 3G & 4G LTE booster can cover areas up to 250 square meters. This makes it ideal for homes, cafes, restaurants, and other medium-sized spaces. If you have a larger area, you might need additional equipment to ensure full coverage.
5.  Q: Can I use the booster with any mobile phone?  
    A: Yes, the booster is compatible with all mobile phones that support 3G and 4G LTE. This includes most modern smartphones. Just make sure your phone is set up to use the correct frequency bands that the booster supports.
6.  Q: What should I do if I have no signal outside?  
    A: The booster needs a weak signal from outside to work. If you have no signal at all outside, the booster won't be able to amplify anything. You can check your signal strength outside before purchasing the booster to ensure it will work for you.
7.  Q: Is the installation of the booster difficult?  
    A: No, the installation of the booster is quite straightforward. You just need to connect the outdoor antenna to the booster and place it in a location where it can receive a signal. The indoor antenna should be placed where you need better coverage. Detailed instructions are provided with the product.
8.  Q: What upgrades are available for the booster?  
    A: You can upgrade the external cables for longer reach, or choose a higher gain Yagi antenna for better performance if your signal is weak. Additionally, a lightning surge protector is available to safeguard your equipment from electrical surges.
9.  Q: Will the booster help with dropped calls?  
    A: Yes, one of the main benefits of using a mobile signal booster is that it helps eliminate dropped calls. By providing a stronger and more reliable signal, you can enjoy clearer voice calls and a more stable connection.
10.  Q: How can I check the signal strength on my phone?  
     A: To check the signal strength on your phone, you can use specific codes or apps. For iPhones, dial \*3001#12345#\* and look for the 'Serving Cell Info'. For Android phones, you can download the 'LTE Discovery' app to see the signal strength and frequency band information.
