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 your phone's connection to mobile networks. It works by receiving the existing weak signal from outside, amplifying it, and then sending that stronger signal inside your home or business. This means better call quality, faster internet, and fewer dropped calls.
- How does the 3G & 4G LTE mobile signal booster work? - This booster works by using two different frequency bands: 1800MHz and 2100MHz. These bands are used by many mobile network providers in Denmark, including Three and Oister. When you install the booster, it captures the weak signals from outside, enhances them, and distributes the improved signal throughout the area, making it easier for phones to connect.
- Who can benefit from using a mobile signal booster? - Anyone experiencing poor mobile signal in their home or workplace can benefit from a mobile signal booster. This is especially useful for families with multiple phones on different networks, cafes, restaurants, and other businesses where strong signals are essential for communication and internet access.
- Will this booster work with all mobile networks? - The booster is designed specifically for 3G and 4G LTE networks using 1800MHz and 2100MHz frequencies. While it enhances the signals for Three and Oister networks, it's best to check with your provider to ensure it supports the correct frequencies in your area.
- How much area can this booster cover? - The 3G & 4G LTE mobile signal booster can cover an area of up to 250 square meters. This makes it ideal for homes, cafes, restaurants, and similar spaces where you want to improve the mobile signal for everyone inside.
- Can I use the booster for 2G calls? - The booster mainly strengthens 3G and 4G signals, but if you have a 4G-ready phone and you're not in a 4G area, you can still use 3G to make calls. This means that you can make and receive calls, even if the signal isn't perfect.
- What if I don't have any signal outside? - It's important to know that the signal booster can only amplify signals that are already there. If you have no signal outside, the booster will not work because it cannot create a signal from nothing.
- How is the booster installed? - The mobile signal booster kit comes with everything you need for installation, including the booster unit, an outdoor antenna, an indoor antenna, and all necessary cables. The installation process is designed to be easy, and you'll be able to set it up on your own without needing specialized help.
- Are there any upgrades available for the booster? - Yes, there are several upgrade options available. You can upgrade the external cables if the standard length isn't enough for your area, or opt for a higher gain antenna if your indoor signals are weak. There's also a lightning surge protector available to safeguard your equipment.
- Can the booster improve battery life on my phone? - Yes! By amplifying the signal, the mobile signal booster can help improve your phone’s battery life. When your phone has a better signal, it doesn't have to work as hard to connect to the network, which can save battery power.
