### Custom your solution
#### **Expandable coverage by adding indoor antenna if the outside signal is strong.**
### **How It Works**
#### 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 takes weak signals from outside, amplifies them, and then broadcasts the stronger signal inside your home or office. This means you can make calls, send texts, and use the internet more easily.
2. Q: How does the 250m2 mobile signal booster work?

3. Q: Is the booster compatible with all mobile networks?
A: Yes, this booster is designed to work with multiple mobile networks, including Three, Vodafone, Eir Mobile, and Meteor. It boosts signals for 2G, 3G, and 4G networks, ensuring you have a reliable connection no matter your provider.
4. Q: Can I use the booster in a large building?
