#### 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.  What is a Mobile Signal Booster? - A Mobile Signal Booster is a device that helps improve weak mobile phone signals. It takes the outside signal, amplifies it, and then sends the stronger signal inside your home or office. This means you can make clearer calls and send texts without interruptions.
2.  How does the Calls - 100m2 Booster work? - The Calls - 100m2 Mobile Signal Booster works by using a special frequency of 900MHz, which is common in India. It captures the existing weak signal from outside, boosts it, and spreads it throughout a space of up to 100 square meters. This helps ensure you have better reception for calls and texts.
3.  Who can use this Mobile Signal Booster? - This booster is designed for users of MTNL and Loop Mobile networks in India. If you often have trouble receiving calls or texts in your home or small office, this device can help you have better communication.
4.  Will the booster work if there’s no signal outside? - No, the Mobile Signal Booster can only increase signals that it can receive. If there’s no signal at all outside, the booster won’t be able to help. It amplifies an existing signal, so a minimum signal outside is necessary for it to work.
5.  How easy is it to install the Booster? - Installing the Mobile Signal Booster is quite simple! You will need to mount the outdoor antenna in a good signal area, run cables into your home, connect everything to the booster, and then plug it in. It's recommended to do a test setup first to find the best location for your antennas.
6.  What comes with the Mobile Signal Booster kit? - The kit includes everything you need for installation: the booster unit, an outdoor antenna, an indoor antenna, cables, and the power adapter. This means you have all the tools necessary for a complete setup.
7.  Can I increase the length of the external cable? - Yes, if the standard 10-meter cable isn't long enough for your setup, you can choose to upgrade to a longer cable when purchasing the booster. This allows you to position the outdoor antenna in the best possible location to capture signals.
8.  What if I want better performance? - If you want improved performance, you can upgrade to a higher gain Yagi antenna. This antenna works better in areas with weaker signals and can be helpful if your phone shows just 1 or 2 signal bars indoors.
9.  Is there a protection option for the Booster? - Yes! You can also upgrade to a Lightning Surge Protector. This is useful for protecting your equipment from sudden surges in electricity during thunderstorms, ensuring your mobile signal booster remains safe and functional.
10.  How can I check if I'm using the right frequency? - To check the frequency band your phone is using, you can dial \*3001#12345#\* on your iPhone. This will show you the frequency information on your device. Alternatively, you can use apps like CellMapper or Network Signal Info Pro to get more detailed insights.
