How It Works

1
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster
2
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
3
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
- Connect the indoor antenna to the MS port.
- Connect the outdoor antenna to the BS Port.
- Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna.
- Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station.
- Power on the booster and check the signal strength.
- 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.

- What is a 4G LTE signal booster? - A 4G LTE signal booster is a device that improves the strength of your mobile phone signal. It works by taking signals from the outside and amplifying them inside your home or office. This helps you enjoy clearer calls, faster internet, and better texting capabilities.
- How does the mobile booster work? - The mobile booster captures weak signals from nearby cell towers and boosts them inside your building. It operates on two frequency bands used by major mobile networks in Singapore: 900MHz and 1800MHz, ensuring that users on different networks like SingTel and StarHub can benefit from improved signal strength.
- Will the booster work if there's no signal outside? - No, the booster needs an existing signal from outside to function. If there is no signal available, the booster cannot create one, so it's essential to check signal strength outside before installation.
- How many people can use the signal booster at once? - The signal booster can support up to 50 users simultaneously. This means that everyone in your home or office can enjoy clear calls and fast data without interruptions!
- What is 4G Calling? - 4G Calling, also known as Voice over LTE or VoLTE, allows you to make voice calls using the 4G network. This typically results in clearer and higher quality phone calls compared to traditional networks. Make sure your phone supports this feature to use it!
- Is installation difficult? - Not at all! The mobile booster kit includes everything you need for easy installation. This includes an external antenna, cables, and the booster unit itself. Even if you're not tech-savvy, you'll find it simple to set up!
- Can I upgrade the cables or antennas? - Yes, if the standard cables included in the kit are not long enough for your area, you can upgrade to longer external cables. Additionally, you can upgrade to a higher gain Yagi antenna for even better performance if needed.
- What should I do if I notice dropped calls? - If you're experiencing dropped calls, it may be due to a weak signal. Installing the mobile booster can help, especially if your phone shows 1 or 2 signal bars indoors. If the problem persists, check if there's enough signal outside.
- What is the Lightning Surge Protector? - The Lightning Surge Protector is a safety device that protects your signal booster from damage caused by lightning. If you live in an area with thunderstorms, this is a good upgrade to have to keep your equipment safe.
- How can I check if my phone supports the required frequency bands? - You can check your phone's frequency bands by using a special code. Just dial *3001#12345#* on your iPhone, press call, and look for 'Freq Band Indicator' in the 'Serving Cell Info'. You can also use apps like 'CellMapper' or 'Network Signal Info Pro'.
