#### 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 the Calls - 100m2 Mobile Signal Booster? - The Calls - 100m2 Mobile Signal Booster is a device designed to improve mobile phone signal strength indoors. It works with major Finnish carriers like Telia, Elisa, and DNA to enhance voice calls and text messages on the 900 MHz frequency. This booster can cover an area up to 100 square meters, making it ideal for small apartments or offices.
2.  How do I install the mobile signal booster? - Installing the mobile signal booster is quite simple! First, place the outdoor antenna in a spot with good signal outside, usually on the roof. Then, connect this antenna to the booster inside your home using the provided cable. Finally, attach the indoor antenna to the booster and plug it in. You can do a loose setup first to find the best positions for everything!
3.  Will this booster work if there is no signal outside? - No, the mobile signal booster cannot create a signal. It can only make a weak signal stronger. If there is no signal available outside, the booster won't be able to help you.
4.  How can I check my mobile frequency band? - You can check your mobile's frequency band by dialing \*3001#12345# on your phone, then tapping the call button. After that, go to 'Serving Cell Info' and look for 'Freq Band Indicator.' Alternatively, you can use apps like CellMapper or Network Signal Info Pro.
5.  What is the difference between the standard and upgraded aerials? - The standard aerial is good for most situations, but upgrading to a higher gain Yagi antenna can provide better performance, especially if you usually have low signal bars inside. It's especially useful if your outdoor signal is already decent.
6.  How many users can connect to the booster at once? - This mobile signal booster can support up to 10 users at the same time, so multiple devices can benefit from the improved signal.
7.  What comes in the booster kit? - The booster kit includes everything you need to boost your signal: an outdoor antenna, an indoor antenna, a power adapter, and cables. Basically, it has all the parts required for a complete installation.
8.  Is it safe to use a signal booster? - Yes, mobile signal boosters are safe to use. They are designed to comply with regulations and do not cause harm to your devices or health.
9.  What if my outdoor signal is weak? - If your outdoor signal is weak, consider upgrading to a higher gain external antenna, which can help improve the signal captured and enhance your indoor reception.
10.  Can I use the mobile signal booster for 4G? - This specific model is designed mainly for 2G signals (like voice calls and texts). If you need 4G boosting, you'll have to check for other booster models that support higher frequency bands.
