### 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. What is a 4G LTE mobile signal booster? - A 4G LTE mobile signal booster is a device that helps improve your mobile phone's signal inside buildings. It picks up weak signals from outside, makes them stronger, and then sends the stronger signal throughout your home or business. This means you can make calls and use the internet without interruptions!
2. How does the 4G LTE booster work? - The booster works by collecting weak signals from the outside using an outdoor antenna. This signal is then amplified by the booster and sent inside using cables. The indoor antenna spreads the better signal across the area, helping devices in that space have better reception.
3. How much area can the 4G LTE booster cover? - The 4G LTE booster can cover areas up to 250 square meters. This is great for medium-sized homes, cafes, restaurants, or even small offices, ensuring that many people can use their mobile devices comfortably.
4. How do I know if I need a booster? - If you often experience weak signals, dropped calls, or slow internet in certain areas of your home or office, you might need a booster. It's common to check your phone's signal strength: if you see only one or two bars, a booster can help!
5. Can I install the signal booster myself? - Yes! The signal booster comes with everything you need to install it yourself. You'll find clear instructions in the package, and many users find it easy to set up. If you need help, customer support is available.
6. What types of mobile networks does the booster support? - This particular booster works with SingTel Mobile, StarHub, M1, and Circles.Life networks. If you're using one of these carriers in Singapore, this booster will help strengthen your signals.
7. Is the booster safe to use? - Yes, using a mobile signal booster is safe. It complies with all regulations and doesn’t interfere with mobile networks. It simply enhances the existing signals, making your devices work better.
8. What if there's no signal outside? - If there is no signal outside, the booster won't work. It needs a weak signal from outside to boost. You can check your outdoor signal before purchasing to ensure it will be effective.
9. What is the upgrade option for the external aerial? - If you have a weaker signal outside, you can upgrade to a higher gain Yagi antenna, which improves performance. This upgrade is beneficial if you see low signal on your phone or in areas where the signal is not reliable.
10. How do I check the mobile network frequency on my phone? - To check your phone's frequency band, you can dial \*3001#12345#\* and press the call button. Then look for 'Serving Cell Info' and you can find the Freq Band Indicator. This helps ensure compatibility with the booster.
