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 mobile signal booster? - A mobile signal booster is a device that helps improve the strength of your mobile signal. It takes the weak signal from outside and amplifies it so you can have better connections inside your home or office. This means clearer calls and faster internet!
- How does the 3G & 4G LTE signal booster work? - The 3G & 4G LTE signal booster works by capturing the mobile signal from outside your building. It then boosts this signal and sends it through an antenna indoors. This makes it easier for your mobile devices to connect and communicate without interruptions.
- Which networks does this booster support? - This signal booster supports multiple networks, including Telia, Elisa, DNA, and Alcom in Finland. It improves both 3G and 4G LTE signals, making it helpful for everyone in your household, no matter which carrier they use.
- What areas can this booster cover? - The booster can cover indoor areas of up to 2,000 square meters, which is suitable for large homes, offices, and even warehouses. This means you can stay connected in spacious places without losing signal strength.
- Can I use my 4G phone in a 3G area? - Yes! If you have a 4G-ready phone but are in an area where only 3G is available, you can still use your phone. The signal booster enhances 3G signals, so you can make calls and use the internet even if 4G isn't available.
- What if I don’t have any signal outside? - If there is no signal outside your building, the booster will not work. The device needs an initial signal to amplify; it cannot create a signal from thin air. So, it's essential to have at least a weak signal outside.
- Is it easy to install the signal booster? - Yes! The signal booster comes with everything you need for installation, including antennas and cables. It's designed to be user-friendly, so even if you're not a tech expert, you can set it up without much trouble.
- What is 4G Calling and how does it work? - 4G Calling, also known as VoLTE (Voice over LTE), allows you to make phone calls using a 4G network. This results in clearer and higher quality voice calls compared to traditional methods. If your phone supports this feature and is boosted, your calls will be sharper!
- What can I do if I need more cable length for the installation? - If the standard 10-meter cable isn't long enough for your installation, you can upgrade to a longer cable. This flexibility ensures you can set up the booster in a way that best suits your house or office layout.
- What is the Lightning Surge Protector and do I need it? - The Lightning Surge Protector is a device that protects your signal booster from damage caused by lightning strikes. If you live in an area prone to lightning, it’s a good idea to have this protector to keep your equipment safe and functioning.
