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 reception of your mobile phone signal. It takes weak signals from outside and makes them stronger, allowing you to make calls, send texts, and use the internet more easily inside your home or any building.
- How does the 3G & 4G LTE Booster work? - The 3G & 4G LTE Booster works by receiving weak signals from the outside, amplifying them, and then sending the strengthened signals to your phone. This makes it easier to use your mobile phone for calls and internet, especially in places where the signal is normally weak.
- Will it work for all mobile networks? - Yes! This booster works with most mobile networks in Slovakia, including O2, Telekom, and Orange. However, it does not work with the Swan 4ka network. So, if you're using one of the supported networks, you should enjoy improved signal strength.
- How big of an area does this booster cover? - The booster can improve your mobile signal in areas up to 250 square meters. This means it is suitable for homes, restaurants, pubs, and clubs where many people might be using different mobile networks.
- Do I need a special phone for this booster? - You don't need a special phone, but it's best if you have a 4G-capable device to take full advantage of faster data speeds. If you're in an area without 4G, you can still use your device on 3G, and the booster will help with that!
- Is it easy to install the signal booster? - Yes, the kit comes with everything you need to set it up, including antennas and cables. Most people can install it without professional help. However, if you want to be sure, you can have someone assist you with the installation!
- What if I still can't get signal after using the booster? - The booster can only strengthen signals. If there is no signal outside, the booster won't be able to help. It's important to have a certain level of signal from your network for the booster to work effectively.
- Can I use the booster with multiple devices? - Absolutely! The 3G & 4G LTE Booster can support up to 25 devices at the same time. This makes it great for families, offices, or places with many customers who need a reliable mobile signal.
- What should I do if I need stronger performance? - If you need even better performance, you can upgrade components like the external aerial for stronger reception. These upgrades are designed to boost the performance even further for those who might be in tough signal areas.
- Where can I find more information about setup? - For detailed setup help, you can refer to the Quick Start Guide on the product’s page, which provides step-by-step instructions to make the installation process easy for everyone.
