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 does a 4G LTE mobile signal booster do? - A 4G LTE mobile signal booster helps improve your mobile phone signals for calls, texts, and data. It works by capturing weak signals from outside and making them stronger inside your home or business, typically covering areas up to 250 square meters.
- Can this booster work with any mobile network? - Yes, the booster can enhance signals for multiple operators in Denmark, including Three, Oister, Telia, Telenor, and more. It supports both 2G and 4G connections, which means it can improve calls and data for many users.
- How can I tell if my phone supports 4G Calling? - To check if your phone supports 4G Calling, you can follow a few simple steps. On iPhones, just dial *3001#12345#*, press Call, and look for the 'Freq Band Indicator' under 'Serving Cell Info'. If you see 'Band 3', then your phone supports it!
- What do I need to know about signal strength for the booster to work? - The booster amplifies existing signals but can't create them. If there's no signal outside your building, the booster won't work. It's best to check the outdoor signal strength to ensure the booster can amplify it effectively.
- Is it easy to install the mobile signal booster? - Yes! The kit comes with everything you need for installation, including an external antenna, internal antenna, cables, and a power adapter. It's designed for easy setup, so you should be able to get it running quickly!
- What does 'Voice over LTE' mean? - Voice over LTE, or VoLTE, means you can make voice calls over the 4G network instead of the older 2G network. This usually results in clearer and higher-quality calls. If you have 4G calling available in your area, the booster will help improve that experience.
- How many devices can use the booster at once? - The booster supports up to 25 devices simultaneously. This means you and your family or friends can enjoy improved calls and data without affecting each other's connections.
- What should I do if I need a longer external cable? - If the standard 10 meters of external cable isn't long enough for your needs, you can upgrade to a longer cable. This way, you can position the external antenna in the best location to capture strong signals.
- What kind of protection is available for the booster? - You can add a Lightning Surge Protector to your setup. This device protects your booster from damages caused by lightning strikes or power surges, ensuring that your equipment stays safe and functional.
- Can I use the booster in different locations? - Yes, you can use the signal booster in various indoor locations as long as it is set up properly. You just need to ensure there is an external signal available for it to function effectively.
